Effect of water stress and absorbent materials application on yield and components yield of fall wheat

Effect of water stress and absorbent substance such as animal manure, zeolite and bentonite in a field trial training - Islamic Azad University in agricultural research is conducted 2010 - 11. Tested in a split plot randomized complete block design with three replications. The experiment consisted of three irrigation treatments (100%, 85% and 70%) required water treatment plant in the main,Use absorbent materials on six levels (controls, 30 tons of manureper hectare, 15 tons of manure + 4 tons zeolite per hectare, 15 tons of manure per hectare consumption of + 2 tons of bentonite, zeoliteof 4 tons per hectare consumption of+ 2 tons of bentonite per hectare and 15 tons of manure+2 tons bentonite + 4 tons of zeoliteper hectare)in sub plots on wheat type alvand. Results showed that the effect of water stress on traits such as plant height, seed weight and seed yield and harvest index of the level of a cluster was significant at five percent. The results show that the use of fertilizers a significant effect on panicle harvest index, number of spikelets per panicle and grain has. highest levels of water stress on grain yield average of 8 / 5 tons per hectare to irrigation based on plant water requirement was 100 percent and lowest average yield of 4/03 tons per acre to plant irrigation was 70% water requirement. The results show that the zeolite used with manure can increase performance. Given the multi-year drought and water restrictions that exist in the country and Zeolite and its five-year price stability can be recommended to reduce the damage caused by irrigation farmers.
