اثر مایکوریزا بر کاهش مصرف کود شیمیایی فسفره، اجزای عملکرد و عملکرد ذرت

In order to study the effect of mycorrhiza at different levels of phosphorus fertilizer on yield and yield components of maize a factorial experimenta based on randomized complete block design with three replications was conducted at the Research Farm Bu-Ali Sina University. Experimental treatments were included values of 0, 20, 40, 60, 80 and 100% recommended phosphorus with non using and using of mycorrhizal .Effect of phosphorus, mycorrhiza and their interaction on all traits was significant. Means comparison of the interaction showed that the highest value for number of seed rows per ear, 100-seed weight and grain yield belonged to treatment of 40% phosphorus fertilizer with mycorrhiza. The lowest value of these traits with reduction of 22.88, 30.46 and 57.53 percent, respectively, were revealed at control treatment (No using of mycorrhiza and phosphorus). Therefore, using of mycorrhiza increased corn yield and decreased consumption of phosphorus fertilizer.
