The growth and development of crops are permanently affected by various environmental factors, and environmental stress is one of the most important factors that reduce the yield of crops in the world. Drought is one of the most important abiotic stresses in plants. Drought stress also aggravates the effect of other stresses or causes them to appear. Considering that Iran is one of the dry and semi-arid regions, water management in the agricultural sector is of particular importance. In this regard, the aim of this research was to investigate the effect of deficit irrigation and foliar application of amino acid on some morphological traits and grain yield of soybean.

The experiment was carried out in the two years of 2018 and 2019 in the farm of the Faculty of Agriculture of Tarbiat Modares University. This research was designed and implemented as a split plot based on a randomized complete block design with three replications. The experimental factors include three irrigation levels (full irrigation, moderate deficit irrigation and severe deficit irrigation), which were placed in the main plots, and foliar spraying of amino acids with five levels (leucine, valine, cysteine, commercial amino acids, without foliar spraying) as sub-plots were considered. The number of experimental plots was 54. In each repetition, three main plots were created at a distance of one meter from each other and 6 sub-plots were created inside each main plot. The distance between the plants on the cultivated rows was 8 cm. Some morphological traits and grain yield of soybean were measured.

Based on the results of the interaction of the year in the irrigation regime, the height of the plant decreased in each year with the decrease in irrigation, but this decrease was not significant in the first year. The results showed that by spraying the plants with amino acids, the height of the soybean plant increased significantly compared to the control, and among the amino acids, commercial amino acid (91.77 cm) and cysteine (91.06 cm) had the greatest effect on the height of the plant, although there was no significant difference with other amino acids. The highest leaf area was related to the plants sprayed by valin in the second year. The results showed that in each year, with the application of amino acids, the leaf area of the soybean plant increased significantly compared to the control. Valine amino acid with the greatest effect on leaf dry weight increased it by 29.57% compared to the control treatment. The results showed that foliar spraying of all four types of amino acids had a significant increasing effect on the dry weight of the stem compared to the control, and cysteine had a 34.6% increase in the dry weight of the stem compared to the control, although there was no significant difference with other amino acid treatments. The results showed that in both years, with the application of amino acids, the wet weight of pods increased compared to the control, and it was significant in the second year. The three interaction effects of the year in the irrigation regime in amino acids had a significant effect only on the characteristics of stem wet weight and pod dry weight.

The results indicated that foliar spraying of amino acids had a positive increasing effect on morphological traits. Valine and cysteine amino acids had the most significant positive effect on grain yield of soybean.

In order to study foliar application of amino acids on morphophysiological properties and thyme essential oil under different irrigation regimes, an experiment was conducted as a split plot based on a randomized complete block design with three replications in the Research Farm of Tarbiat Modares University Faculty of Agriculture in the year 2020 crop season. Experimental factors were irrigation regimes at three levels including normal irrigation, moderate water stress, severe water stress (withholding irrigation until  25%, 45% and 65% of soil available water depletion in the root zone respectively and then irrigation up to field capacity from plant establishment to harvest time), were randomized to the main plot units and spraying at 6 kinds (aspartic acid, tyrosine, proline, commercial amino acids, distilled water and without spraying) were located in subplot units. The results showed that with reduction of irrigation to the level of severe water stress, plant height, fresh and dry weight of leaves, leaf area, total chlorophyll, percentage of essential oil decreased, and glycol peroxidase and proline showed a significant increase compared to optimal irrigation. Catalase activity also increased under moderate water stress and decreased under severe water stress. Foliar application of amino acids had a positive additive effect on the studied traits. The highest essential oil yield (about 11.20 kg/ha) was assigned to plants under commercial and proline amino acid foliar application under full irrigation conditions. Based on the general results of proline foliar application, increasing the concentration of osmolites such as proline under water stress conditions was able to help the plant withstand drought stress by helping to maintain osmotic pressure and compensate for part of the reduction in growth and dry weight. Therefore, consumption of this type of amino acid under stress conditions is recommended to reduce the effects of drought stress. Under non-stress conditions, foliar application of this type of amino acid had the greatest effect on plant growth and yield.

In order to evaluate the effect of water deficit stress and foliar application of zinc oxide nano particles on morphophysiological characteristics in Withania coagulans L. landraces, a factorial experiment in a completely randomized design with 3 replications was setup. The experiment included various irrigation regimes (control), (medium stress), (severe stress), four landraces (Fanuj, Khash, Saravan and Sarbaz), with and without foliar application of zinc oxide nano particles. The experiment was conducted in green house of the faculty of Agriculture, Tarbiat Modares University, during 2018-2019. The highest leaf area (538.92 cm2) was related to Sarbaz in control irrigation and the lowest leaf area (245.88 cm2) was related to Khash in severe water deficit stress. Based on the comparison results, the mean of maximum plant dry weight (1.76 g) was related to Sarbaz and control irrigation and the lowest plant dry weight (0.63 g) was related to Fanuj and severe water deficit stress. Also, the highest amount of chlorophyll a (2.55 μmol.g-1) was related to Khash, control irrigation and foliar application of zinc oxide nano particles. The highest amount of chlorophyll b (1.26 μmol.g-1) was related to Fanuj, control irrigation and foliar application of zinc oxide nano particles, which was not significantly different from other landraces. Also, the lowest amount of chlorophyll b (0.62 μmol.g-1) was related to Khash, severe water deficit stress and without foliar application of zinc oxide nano particles. Sarbaz had the highest amount of anthocyanin (0.3 μmol.g-1) in the treatment of severe water deficit stress and lack of foliar application of zinc oxide nano particles, which was not significantly different from Saravan. Also, the lowest amount of anthocyanin (0.146 μmol.g-1) was related to Fanuj in the treatment of severe water deficit stress with foliar application of zinc oxide nano particles. Severe water deficit stress reduced the amount of traits tested. Also, the Sarbaz showed good tolerance to water deficit stress conditions compared to other landraces. The foliar application of zinc oxide nano particles also improved plant growth and increased some of the tested traits under stress conditions.

A split-split plot field experiment using the randomized complete block design with three replicates was carried out to investigate drought tolerance of wheat inoculated with mycorrhiza fungi and its interaction with copper nanoparticles. The factors included two irrigation levels (optimum irrigation and deficit irrigation), two levels of fungal symbiosis (with or without a symbiotic relationship), and three spray concentrations of copper oxide nanoparticles (50, 250, and 450 ppm).The results of ANOVA revealed that Analysis of variance showed that proline content and spike/m2 were significant in irrigation regime, mycorrhiza, foliar application, and all the interaction effects of double and triple factors.The effect of irrigation regime, mycorrhiza and foliar application of copper nano oxide was effective on grain yield, but the effects and interactions of irrigation regime×foliar application, mycorrhiza×foliar application and irrigation regime×mycorrhiza×foliar application have no significate effect on that characteristic;Comparison of mean traits showed that the maximum number of spikes/m2 in mycorrhizal fungi application with50ppm copper nano oxide foliar application in optimum irrigation was780numbers.The highest hectolitre weight of wheat was related to triple interactions,optimum irrigation with fungus and foliar application of450ppm copper nano oxide that was not statistically significant effect with triple interactions,optimum irrigation without fungus and foliar application of 250ppm copper nano oxide.Maximum proline content was obtained in non-mycorrhizal fungi treatment with50ppm foliar spray under deficit irrigation (23.8mg/g fresh weight) which was statistically significant at least at5%level with other treatments. The highest grain yield (309.61g/m2) belonged to optimum irrigation treatment and minimum grain yield was observed in severe deficit irrigation.

Sufficient soil fertilization is one of the main requirements for production of barley improvment. To study the effect of different organic fertilizers on yield and yield components of barley cv. Reyhan, an experiment was conducted based on randomized complete block design with three replications with 16 fertilizer compounds. Barley morphological traits, yield and yield components were measured. Treatments were included wood vinegar, 5, 10, and 150/00 as soil application, azocompost, zeolite, wood vinegar, 5, 10, and 150/00 as foliar spraying, wood vinegar, 5 and 100/00 + azocompost, wood vinegar, 5 and 100/00 + zeolite, humic acid, wood vinegar, 5 and 100/00 + humic acid. Application of wood vinegar at 50/00 rate + zeolite significantly increased leaf area and plant dry weight. Also, using vinegar at 100/00 rate + zeolite significantly increased spike length and grain yield. Application of vinegar at the rate of 100/00 with zeolite is recommended in barley cultivation.

Barley is one of the most adapted cereals cultivated in favorable weather conditions, in fertile soils with high water retention potential, as well as in soils with acidic properties of between 7 and 8. This plant is more resistant to wheat than drought and therefore in a climate where water limits the production of cereals, barley can produce the highest yield, and in rainfed conditions, barley performance is higher than wheat and rye. The phenomenon of dryness in Iran is one of the most important factors limiting agricultural production. A large part of the cultivated land is located in arid and semi-arid regions of Iran. In these areas, yields are drastically reduced due to lack of water resources. The use of water stress strongly reduces the components of yield and biological functions and grain. The use of nanofertilizers leads to increased nutritional efficiency of nutrients, reducing soil toxicity, minimizing the negative effects of excessive use of fertilizer and reducing the frequency of application of fertilizers. Fertilizer particles can be scaled with membranes Nano-coating that facilitates the slow release of nutrients. Covering with nanoparticles, makes it possible to regulate the release of nutrients from the fertilizer capsule, which causes the fertilizers to release nutrients regularly and prevent their general fixation. To evaluate the effect of foliar application of iron and manganese in the form of nanoparticles on yield and yield components of barley (Hordeum vulgare L.) under drought stress at different growth stages in the plot field experiment with a randomized complete block design with water stress factor in barley varieties of basil in the main plot factor of iron and manganese fertilizers with manure micro nano iron and manganese (as usual) in the sub-plots and three replications 95-94 conducted in Tarbiat Modarres University. Foliar fertilization of iron and manganese nano-silicates (in the usual manner) with the application of manganese nitrogen fertilizer application of 11 levels, including concentration of one per thousand manure of iron nano-chelate, three per thousand manure of iron nano-chelate, one and a half per thousand nanoseconds Manganese chelate three per thousand manganese nanoclat manure, one per thousand manure of nano chelate of iron and one and a half per thousand of nano manure Manganese chelate, one in a thousand manure of nano-chelate of iron and three in a thousand manganese nano-manganese manure, one and a half per thousand manganese nano-manganese manure and three in a thousand manure of iron nano-chelate, three in a thousand manure of iron nano-chelate and three in a thousand manure nano Manganese clath, without spraying (control), pure water dispersion and recommended iron and manganese nano chelate fertilizer, as a substrate and And irrigation regimes at three levels: 1) No stress and irrigation time when the amount of water available for use in the plant was at 50% FC level; 2) Water deficit at irrigation and vegetative stage was performed when the amount of plant water available on the surface 30% FC of the field was in the vegetative stage, and 3) dehydration in the reproductive and irrigation stage was performed when the amount of plant water available at the level of 30% FC in the reproductive stage was the main factor. Findings:
The results showed that application of nano-iron and manganese levels in vegetative and reproductive stages, increased the yield, especially in the vegetative growth stage, while the control foliar application (without spraying) had the lowest yield. The interaction of nano-iron and manganese and different levels of water deficit stress was significant on all measured traits. The results showed that withholding irrigation at reproductive stage, reduced the yield and the use of nanoparticles cause to increase the yield and yield components. Therefore, the harmful effects of water deficit on plants can be reduced by foliar application of nano-iron and manganese micronutrients.

IntroductionCanola (Brassica napus L.) is one of the most important plants to produce edible oil in Iran and in the world and also one of the negative factors for crop plants is the relative salinity of irrigation water in some areas of Iran. According to the researchers, salinity incorporates high concentration of minerals that prevents plant growth. Effects of Salinity significantly in arid and semi-arid areas, areas with limited rainfall, high temperatures combined with high evaporation with high chemical fertilizers, and poor water and soil management, is observed and is an important crop production problem in these areas. Zeolites are a group of natural porous minerals that acts as a molecular sieve with its crystal structure practices and allow some passage of some ions and block the passage of some others, due to open channels in their ionic lattice. Due to zeolites high porosity and stems from its crystal structure, they can absorb up to 70% of bulk with water. Recent research on various applications of zeolites in crop plants as well as its effect on the process of how to prevent the entry of toxic ions such as sodium and absorption of essential nutrients has been concentrated crop and the interaction effect of the two substances necessary to appear on canola This experiment intends to determine the ways of control damage caused by 5 and 10 10 ds m-1 salinity on yield and yield components on four canola cultivars with application of 8 ton hec-1 zeolite.
Materials and methodsThe experiment was conducted as split plot factorial in randomized complete block design with three replication at the greenhouse research station of Agricultural Faculty of Tarbiat Modares University started in autumn 2013 and at the end of spring 2014 greenhouse operation was ended. Treatments were salt stress from beginning of flowering at three levels included control, 5 and 10 ds m-1, zeolite application with two levels included control and 8 ton hec-1 and varieties with foul levels Zarfam, Sarigol, Hayola and RGS. From 29 October 2013 (sowing) to 20 May 2014 (harvesting), Greenhouse environment was with normal light and temperature conditions. The soil of pots was sand mixed with field soil in ratio of 1:1. Applied zeolite was clinoptilolite. To creation of appropriate drainage and prevent the accumulation of salt, three holes with one centimeter diameter was generated at the bottom of each pot. Salinity was started by adding salt mixture to irrigation water, before flowering. The final salt was mixed with salt water of Tehran, Gom and Kashan wells with ration of 2:2:4:3:4 and after standardization calculated with electrical conductivity meter and finally the salt water was transferred to each pot with graduated containers. On this experiment grain yield, yield components, yield and oil percentage and SPAD were measured. Mean comparisons were performed by LSD test using in SAS 9.2.
Results and discussionThe results showed that the effect on all traits except harvest index was significant, and none of the treatments had no significant effect on oil percent Number of grain per pod, and salt stress did not affect harvest index and zeolite on grain yield, number of pods, number of grain per pod, harvest index and greenness significant effect. Results showed that application of zeolite increases grain yield 9 and 26 percentage in control and average stress levels of RGS. But in severe stress condition because of severe prevent water absorption by increasing the osmotic potential into the roots environment, had not significant effect on experimental varieties. Application of zeolite in control condition and non-application of zeolite in severe stress on Zarfam number of pod were the highest and lowest with the difference of 36 %, respectively. Sarigol in control condition and Zarfam in severe showed the highest and lowest of 1000 grain yield with the difference of 22 %, respectively and RGS in control condition and Hayola in severe showed the highest and lowest of number of grain in pod with the difference of 54 %, respectively. It was also observed that application of zeolite in control stress condition on RGS and non-application of zeolite on Hayola in severe stress condition showed the highest and lowest of dry weight with the difference of 50 %, respectively. Results showed that, Sarigol in control condition of salt stress and zeolite was the highest of oil yield compared to Zarfam in condition of severe stress and non-application of zeolite with 66 percentage. Results of the experiment was shown, Zarfam in average stress and non-application of zeolite showed the highest amount of SPAD compaire to the same variety in severe stress and non-application of zeolite with more than double.
ConclusionsApplication of Zeolite increases grain yield of Zarfam and all three levels of salinity reduces this trait in canola varieties, significantly. Due to the low price (500 rials per kg) of zeolite and abundance of this mineral in our country, it can be used to prevent performance degradation of the material used in high salinity lands. Sarigol showed higher values of SPAD index than other cultivars, in terms of salinity and application of zeolite prevent the reduction of SPAD index values in terms of stress.

In order to evaluate the effect of calcium silicate on salt stress tolerance of four canola varieties, a factorial experiment was conducted as randomized complete block design arrangement in factorial with three replications at the Greenhouse Research Station of Agricultural Faculty of Tarbiat Modares University. Treatments were salt stress levels at the beginning of plant flowering to seed maturation including (control, 5 and 10 dS m-1), calcium silicate (control and 8 kg hec-1) and canola varieties Zarfam, Sarigol, Hayola and RGS. Application of calcium silicate was performed with irrigation the pots simultaneously. Results showed that Sarigol in control condition of stress and Zarfam in severe stress condition produced the highest and lowest seed yield with difference of 67 percent. Application of calcium silicate increased HI. In rate of 8 percent. Zarfam and Hayola dry weight was decreased 24 percent more than the Sarigol in severe stress condition. Severe salt stress decreased oil yield significantly in all of varieties, compared to the control. In general, calcium silicate application increased yield and some yield components. At severe salt stress, calcium silicate increased spad in Zarfam and Sarogol varieties.

Wheat (Triticum aestivum L.) is one of the most important and strategic products in the world with 217 million hectares of the world's highest cultivation area and a total production of 651.4 million tons with an average yield of three tons per hectare (Anonymous, 2015) and more than any other product that supplies calories to the world (Ahmadi Lahijani & Emam, 2013). Drought is one of the most important environmental stressors in crop production around the world (Omidi et al., 2012). One of the most important environmental stresses that most plants face is drought stress (Afzal et al., 2006). Fathi Amirkhiz et al. (2010) also observed that the iron absorption and iron concentration increased significantly with iron nitrous oxide compared with iron oxide in wheat. Pahlavan Rad et al (2007) reported an increase of 21% yield in wheat grain in the study of the effect of iron plowing in wheat.
To study the impact of nano iron and manganese chelates foliar application on mitigating the effects of water deficit and foliar application of nano iron and manganese chelated on yield, yield components of wheat an experiment was carried out in 2014-2015 in the Agricultural Research Farm Station of Tarbiat Modarres University, Tehran as split plot in a completely randomized blocks design with three replications. Iron and manganese nano-silicate fertilizers with iron and manganese micro-chelate fertilizers include 11 levels of concentration of 1 in 1,000 nanoclusters of iron (F1), 3 in 1000 nano chelate iron (F2), one and a half per thousand nano chelate of manganese F3), three per thousand nano chelate of manganese (F4), one per thousand nano chelate of iron, one and a half per thousand nano chelate manganese (F5), one per thousand nano chelate of iron and three per thousand nano chelate of manganese (F6), one And half a thousand nanoclat of manganese, and three in a thousand nano chelate iron (F7), three in a thousand nano chelate of iron, three in a thousand nano chelate of manganese (F8), without spraying (F9), purification of pure water (F10), and Recommended micro-fertilizer complex (F11) as a substrate and drought stress At three levels without irrigation cut (S1), irrigation cut off at vegetative stage until a 70% crop was unloaded (S2) and irrigation was discontinued at the reproductive stage until the 70% crop was unloaded (S3) as factor The main one was examined.
The results showed that factors interaction on Seed yield, Spike number, Grain number in spike, Leaf, Shoot and Spike dry weigh and Leaf area (P≤ 0.01). The results of the comparison showed that the highest Seed yield (2611 Kg/ha) and Grain number in spike (number 52 per m2) was obtained the Three in thousand nano-iron and thousands and a half nano- manganese in without stress treatment. According to Movahdi Dehnavi (2001), drought stress at reproductive stage limits the transfer of iron and manganese to grain. The stress in grain filling stage reduces grain yield by reducing the length of the period (Alizadeh et al., 2010). The number of seeds per spike decreases with drought stress and the number of seeds per spike in vegetative stage is more sensitive than the reproductive stage. In fact, drought stress reduces the growth period of vegetative growth. By reducing the length of this period and passing the plant faster than this stage, the number of nodes and the length of the internode decreases in the plant, and subsequently the plant height decreases (Daneshian, 2000). The cause of lower plant height due to water stress can be due to the reduction of thoracic pressure and prolonged cell growth (Upadhyaya and Panda, 2004).
The results showed that drought stress reduces yield and Application of nano iron fertilizer with magnesium reduces the negative effects of drought stress. Therefore, in case of drought stress by using nano iron and manganese fertilizers to reduce stress.

Organic matters are useful sources to improve soil quality and increase the yield in plants. In order to assess the effects of different fertilizers application on yield and yield components of barley (Hordeum vulgare L. Makoii cultivar) under water stress, a field experiment was conducted on Research Farm of Faculty of Agriculture of Tarbiat Modares University at growing season 2014-2015. The experiment was conducted as split plot arranged in a randomized complete blocks design with three replications. The main plots were three water stress (optimal irrigation, withholding irrigation at vegetative growth stage and reproductive growth stage) and six levels of fertilizers (control, manure, municipal waste chopped, vermicompost, azocompost and urea) were in subplots. There was a significant effect of water stress and fertilizers on the plant height, grain yield, biological yield, grains per spike and number of spike per m2. Overall, the plants were more sensitive to water stress at the reproductive stage and vermicompost and azocompost could moderate disadvantages of water stress on plants.

Proper plant nutrition is an important factor in improving product quality and quantity. In plant nutrition, not only must every element available to plants is enough, but respect the balance and balance of nutrients is very important. Over the years with the indiscriminate use of chemical fertilizers, especially nitrogen and phosphorus, and failure to comply with nutrient balance considerable damage to agricultural land and thus entered (Tohidi Moghadam et al., 1386). Beneficial soil microorganisms one of the determinants of plant health and soil fertility, because in several key processes, such as biological control of pathogens, rotation of nutrients and seedling establishment (Rosas et al., 2008). While chemical fertilizers in the last 50 years have had a major role in increasing crop yield but the problems were created which dropped their positive effects and negative outcomes. Although nitrogen is not a limiting resource, but converts atmospheric nitrogen into nitrogen fertilizers requires the use of fossil fuels is limited besides these sources, the cost of production of these fertilizers will also increase (Herzog et al., 2008). Soil microorganisms are important components of the soil system, because not only help to access elements in the soil, but also sticking soil particles and aggregates stability and thereby improves soil structure and reduce vulnerability to erosion (Stamford, 2008). Soil and plant growth promoting bacteria (PGPR) are soil free-living bacteria. These bacteria are often seen near or even inside the plant roots (Rasouli et al., 1382).
In order to study the effects of integrated application of bio and chemical fertilizers as well as application method of biofertilizer on the yield and yield components of maize (Zea maize L.), an experiment was conducted in 2015 in Babol, in a factorial arrangement with completely randomized block design with three replicates. Treatments were integrated application of biological and chemical fertilizers in four levels (chemical fertilizer, ¼ chemical fertilizer biofertilizer, ½ chemical fertilizer biofertilizer, biofertilizer) and biofertilizer application method in three levels (seed inoculation, fertigation and seed inoculation fertigation).
Result showed that integration of biological and chemical fertilizer affected yield and yield components. The highest grain yield was obtained by application of biofertilizers ½ chemical fertilizer. The greatest and lowest harvest indices were recorded in chemical and biofertilizer treatments, respectively. The highest number of grains per ear (41.3) related to treatment (50% chemical fertilizer biofertilizer). The highest 1000 seed weight belonged to treatment (chemical fertilizer biofertilizer) by 394 Biological fertilizer application methods had no significant effect on 1000 grain weight but highest 1000 seed weight were treated with inoculation fertigation by 346.67. The method of application seed treatment irrigation method compared to the other two methods showed more favorable results, although the difference was not statistically significant. Vessy (2003) Stated that biological fertilizer material that has live microorganisms that when the seed, the plant or the soil used in soil or in plant root growth area occupied and plant growth by providing access some essential elements, stimulate. Vessy (2003) also reported that the importance of bio-fertilizers for biological nitrogen fixation by them. This researcher said that with the growth promoting bacteria capable of fixing molecular nitrogen, This consolidation was small and major biological fertilizers through the secretion of growth hormone auxin was especially Which increases the total volume of root hairs Thereby increasing the permeability of the roots and increasing the absorption of nutrients.
The results showed that combined application of these resources while increasing corn yield a significant decrease in the consumption of chemical fertilizers.

One of the main reasons of crop yield reduction in Iran is salt stress and providing proper strategies is necessary for mitigating the effect of this stress. So, a factorial experiment was conducted to improve the salt stress damages on two canola varieties in a randomized complete block design with three replications at the Research Greenhouse of Agricultural Faculty of Tarbiat Modares University. Treatments included 3 levels of control, moderate, and severe salt stress (0.4, 5 and 10 dS m-1), calcium silicate at two rates (0 and 8 kg ha-1), two levels of zeolite (control and 8 ton ha-1) and two varieties, namely, Zarfam and Sarigol. Results showed that application of zeolite increased Zarfam yield in soil with a light texture and had no significant effect on Sarigol. Under moderate salinity, zeolite, and calcium silicate treatment, Zarfam produced higher oil percentage (more than 57%) compared to Sarigol at severe stress and without application of zeolite and calcium silicate. Also, Sarigol in the treatment with no salinity stress and zeolite and only application of calcium silicate had the highest oil yield while the lowest oil yield (60 percent lower) was obtained at severe stress, application of zeolite and without application of calcium silicate . In the treatment with moderate salinity and non-application of zeolite and calcium silicate, Zarfam had the highest SPAD, while Sarigol, under moderate stress, application of calcium silicate and without application of zeolite, had the lowest SPAD (more than 32% difference). Generally, salt stress reduced yield and yield components of both varieties and application of zeolite and calcium silicate decreased the damages of salt stress in some traits. Besides, Zarfam showed better response to the calcium silicate and this treatment was more effective in comparison with zeolite in both canola varieties.

Background and objectives Nitrogen is one of the limiting factors for crop production in the world. However, a large percentage of the fertilizer used in the leaching and evaporation loss, need more material to help illustrate the effect of nitrogen fertilizers better. Studies have demonstrated various sources of nitrogen have a significant effect on its performance. Some researchers has reported the influence of ammonium absorption in plants. Application of superabsorbent materials can increase root surface and dry weigh 27 percent compare to the control. In this study, zeolite, super absorbent polymer clay as an effective material for reducing leaching and gelatin capsules as a barrier to reduce evaporation and leaching of fertilizers and nitrogen partly urea, ammonium sulfate, potassium Nitrate were compared.
Materials and methods To improve the effect of nitrogen fertilizers on the yield of oilseed rape, factorial experiment in a randomized complete block design with three replications was conducted as a pot in Tarbiat Modarres University research. Treatments were auxiliary materials in six levels (control levels, 8 and 4 mL gelatin capsules, zeolite (8 ton ha-1), super absorbent polymer (100 kg ha-1) and clay (to the extent that the clay soil Level 25% required) and without application auxiliary materials. And chemical fertilizers in four levels (urea, potassium nitrate and ammonium sulfate, respectively. The amount of each chemical fertilizers based on the delivery of 40 kg N ha for each pot was calculated in two steps by installments. All treatments were applied to the soil.
Results In the present experiment there was no significant difference in the number of seeds per plant between different levels of fertilizers in terms of the on use of auxiliary materials. The results showed that the use of gelatin capsules plus urea and the use of clay without the use of fertilizers had the highest and lowest yield respectively, with the1.6 grams difference. The use of gelatin capsules and clay in terms of urea were found highest and lowest percentage of oil, respectively, with 8.8% difference between. Zeolites and clay with 0.211 grams difference, urea and potassium nitrate with 0.17 grams of oil were the highest and lowest oil yield. It was also found urea fertilizer with zeolite or clay could increase SPAD index values relative to control.
Conclusion The results of this experiment showed that the use of these substances, especially gelatin capsules, can help to increase the impact of nitrogen fertilizers and yield, especially rapeseed oil to improve performance.

To reduce the damages of water deficit stress on safflower with zeolite and chitosan, an experiment was conducted as split plot factorial in randomized complete block design with three replication at the field Research Station of agricultural Faculty of Tarbiat Modares University. Treatments were water deficit stress {(control (Irrigation after 50 percent), moderate stress (Irrigation after 65 percent) and intensive stress (Irrigation after 80 percent) discharge of available moisture}, zeolite (control and 4.5 ton hec-1) and chitosan (non sprayed, distilled water, 1 percent acetic acid, 0.05 percent chitosan and 0.5 percent chitosan). Result showed that intense stress decreased yield, half the maximum value compared to control but whit zeolite and 0.05 percent chitosan this amount was reduced to 19 percent. Oil yield increased under non-zeolite application and intensive water deficit with foliar application of 0.05 percent chitosan, about 63 percent. Application of zeolite and 0.5 percent chitosan showed the highest number of capitol that was 26 percent higher than zeolite application and non sprayed. We conclude that zeolite and chitosan application can reduce damages of water deficit stress and increase growth and yield of this plant.

Due to reduction the crops yield and yield components in water stress condition, a factorial experiment was conducted in a randomized complete block design with three replications to evaluate the effect of water deficite stress and growth improver materials on canola (Brassica napus L.) yield and yield components in research greenhouse of Agricultural Faculty of TarbiatModares University. Treatments includes water deficit stress {Control (50% discharged available water) (S1), average stress (65% discharged available water) (S2) and sever stress (80% discharged available water) (S3)} and foliar application {Control (F1), distilled water (F2), calcium silicate (F3), Hexaconazole (F4), propiconazole (F5), and penconazole (F6)}. Results showed the highest of yield was related to S1F6 that showed 2.1 gr higher than S2F1. Also S1F6 and S3F1 With more than 2-fold difference were the highest and the lowest of thousand seed weight. Also in S2, control and foliar application of F4 were the highest and the lowest of oil percentage respectively with 34.4% difference. S1 and S2 with no significant difference were lower than control with a significant difference proximately 5.8 µmol co2 m-2 Leaf s-1 in photosynthesis rate. S1F2 and S3F1 were the highest and lowest stomatal conductivity with 0.154 mol H2O m-2s-1 difference. Also S1F1 was the highest amount of intercellular Co2 concentration with 229 µmol CO2 mol air -1 difference with S3F2. So foliar application of triazoles (penconazole) and calcium silicate somewhat reduces the water deficit stress damages.

This study aims to design a causal business management competency model for managerial jobs of Ansar Bank. This study uses a descriptive-survey method in which 150 Ansar Bank managers were sampled by purposive sampling and then studied in 2012. Data collection was made by a researcher-made questionnaire. The instrument validity was assessed and verified based on the comments of university professors who were dealing with the subject of this study, while taking advantage of principal component analysis method and latent variables measurement fitting using confirmatory factor analysis. The reliability was measured by Cronbach’s alpha which revealed a reliability of (R=864%), and as it can be claimed the instrument enjoys a good reliability. To test the hypotheses of this research, structural equation modeling was used. The results verify all primary and secondary hypotheses of this study and reveal the effectiveness of competencies included in Business Management Competency Model for Managerial Jobs of Ansar Bank.The variable of customerorientation enjoys the highest level of effectiveness. In other words, it enjoys the most significant relationship with business management and afterwards the variables of communications, modifications, resource management come respectively.

In order to investigate some qualitatives indices of sunflower (Helianthus annuus L. var. Azargol) with zeolite application and different levels of irrigation، an experiment was carried out in Varamin، Iran، on 2012. Field experiment was conducted based on randomized complete block design with factorial split-plot arrangement each at three replications. Irrigation factor was chosen at three levels including: normal irrigation، drought stress at flowering stage and drought stress at seed filling stage in main plots. Zeolite was used at three levels، no application، 6 ton per hectare and 12 ton per hectare in sub plot. Germination percentage، germination rate، seedling dry weight، radicle، plumule dry weight and oil percentage were measured. The results showed that normal irrigation increased all of the traits and drought stress at flowering and seed filling stages decreased all of the traits. The highest values of the measured traits related to normal irrigation with 12 ton per hectare zeolite application and the differnence was not significant with 6 ton per hectare zeolite treatment.

In order to study the effects of free living nitrogen fixing bacteria and nitrogen chemical fertilizer on yield components of corn cultivar SC 647, a factorial experiment based on randomized complete block design with four replication was conducted at Varamin, Iran in 2010. The factors in this study included Azospirillum, Azotobacter and nitrogen chemical fertilizer. Azospirillum consisted of two levels (non application-application), Azotobacter consisted of two levels (non application-application) and nitrogen chemical fertilizer consisted of two levels (application of net nitrogen chemical fertilizer at the rate of 200 Kg ha-1 and application half of net nitrogen chemical fertilizer at the rate of 100 Kg ha-1. Results revealed that with application free-living nitrogen fixing bacteria with half rate nitrogen chemical fertilizer increased all of traits except seed number in row.
