بررسی اثرات کشت مخلوط نسبت های مختلف بذر واریته های سویا در افزایش راندمان

A mixed soybean seed is a mixture of two or more seeds cultivars that its yield is usually equal or more than performance of each cultivar in pure cultivation. the othe advantage is that the mixture is protective against the some diseases and pests accidentally some years. According to various degrees of susceptibility to various stresses, including of drought, salinity, and continuous rainfall, planting mixtures is better than pure cultivation. So in order to investigate the effects of mixed cvropping of two different soybean cultivars, a randomized complete block design with four replications for three years was carried out.Treatments included of four varieties ( ) B- / - , ( ) B- / - , sari and Telar and different ratios of seed mixing % ا %, % ا %, % ا % for different varieties. At the end of each year analysis of variance was done by Duncans test.. At the end of the third year of combined analysis of variance conducted to determine the profit mix. all treatments in different years in terms of major disease area charcoal rot were considered. Meanwhile, treatments compounds (Sari(Jk- ) % + %), (Sari(Jk- ) % + %) were produced the highest yield . and . tons per hectare, respectively. The rate infection of mixed cropping was and . percent that had less pollution than pure cultivation.
