To study the effect of deficit irrigation and zeolite application on water use efficiency, oil yield and phenology of hemp, a split plot experiment was conducted in a randomized complete block design with three replications in Shahrekord University. Treatments included irrigation at four levels (supplying 40, 60, 80 and 100% water requirement of crop) as the main plot and application of zeolite at three levels (no application, application of 5 and 10 tons of zeolite per hectare) as sub plot.
The results showed that the length of the reproductive period was affected by irrigation and zeolite treatments and their interactions. By decreasing irrigation water supply, the length of the growth period decreased, although the reproductive stages were more sensitive than the vegetative stages. With increasing defficit irrigation intensity, oil yield, as a function of grain yield and oil content, decreased significantly. But, zeolite application prevented the oil yields to be reduced to some extent. Zeolite improved the water consumption per unit of yield on low and medium levels of drought stress with 19.9% and 17.5% than control treatment. Application of 10 tons of zeolite per hectare, at 60 and 80 percent supplying of the crop water requirement, modified the adverse effects of drought stress to hemp.

Mung bean is one of tropical and semitropical pulses that is important in food، fodder، green manure and improves soil fertility and is a cheap source of protein in human direct consumption. The use of zeolite in soils with heavy texture، because it keeps moisture and nutrients around the seeds and roots is very important. On the other hand، the application of techniques of improving seed quality such as priming، improves seed germination in condition of nutrients limitation. This experiment was conducted as a factorial in Randomized Completely Block Design (RCBD) with three replications in the farm of the Ramin University in August 2011. Experimental factors included Culture System Optimization (CSO) in six levels Zeolite application+ seed priming (O1)، Zeolite application (O2)، seed pelleting+ seed priming (O3)، seed pelleting (O4)، seed priming (O5) and control (O6) with three mung bean cultivars included Hendi (C1)، NM-54 (C2) and VC11-18b (C3). The results showed that cultivar was a significant effect on all of the traits; however the effects of CSO on spad index، nitrogen harvest index (NHI)، rate of biological yield accumulation and grain yield production rate weren’t significant. Hendi cultivar showed the highest grain filling rate. Combination of Hendi seed pelleting with zeolite and zeolite application and Hendi cultivar were obtained highest of grain yield، grain protein content and harvest index. Priming of Hendi seeds produced the highest biological yield and showed that the reactivity of Hendi cultivar in usage agronomic factors was higher than other cultivars and was promising for green manure planting.

Garlic is one of the important medicinal plants that it''s plants in many origins. The intercropping of plants is a view of sustainable agriculture that it''s very useful. To evaluate the potential of Garlic in intercropping with medicinal plants، this study was conducted as a Randomized Complete Block Design (RCBD) with three replications at the Ramin Agriculture and Natural Resources University in 2011-2012. Treatments were includingGarlic intercropping with Psyllium (Plantago ovata)، Black Seeds (Nigella sativa)، Ajowan (Carum copticum)، Fennel (Foeniculum vulgare)، Marigold (Callendula officinalis) and Dill (Aniethum graveolens) that planted withthe 50:50 proportion inan interstitial cultureand also، pure culture of above plants. Relative advantage of Garlic intercropping with medicinal plants in terms of Relative Value Total (RVT) was only shown in Garlic intercropping with Black Seeds with 2. 04. The most of the amount of increasing actual yield was related to intercropping of Garlic with Psyllium with 1. 78. The pure yield of Garlic (7330 kg/ha) and intercropping of Garlic with Ajowan (2300 kg/ha) were the highest and lowest yield، respectively. There was a high significant difference with high correlation between intercrop treatments in terms of the number of bolblet in Garlic. When the number of irrigation (water required plant) increased، Garlic yield was reduced. However، a direct relationship was found between total relative value and number of irrigation. Finally، intercropping of Garlic with Psyllium and Marigold because of the high amount of Actual Yield Total (AYT) is proposed in this region.
