نحوه تاثیر قارچ میکوریزا و کود فسفر در کاهش اثرات تنش کم آبی در لوبیا قرمز

To investigate the consequences of the application of mycorrhiza to reduce the use of water in agriculture, phosphate and resistance to bean field experiment in 1391-1392 at the Agricultural Research Center, Arak city as split factorial in the form of randomized complete block design with three replications. Experimental factors include water stress at three levels ( irrigation after 60 , 90 and 120 mm evaporation from pan class A) in the main plots , the second factor, Triple super phosphate, in 3 levels ( zero , 50 and 100 % of the recommended amount) and the third factor mycorrhiza in two levels ( no application, and the application of fungus Glomus mosseae) , respectively. The results showed that with increasing water stress, plant height, pod length and seed weight decreased, but the application of mycorrhiza significantly increased all the characteristics. Also, 50 percent of the required amount of phosphate fertilizer also resulted in improved traits were estimated. Finally, it can be stated that the average severity of dehydration effective application of mycorrhiza fungi and small amounts of phosphate fertilizers in agriculture beans can be partly the effect of dehydration overcome.
