اثر کود بیولوژیک حاوی میکوریزا آربوسکولار بر عملکرد و اجزای عملکرد ارقام مختلف برنج

In order to study the efficiency of biological fertilizer consumption in rice fields, an experiment was conducted in ۲۰۱۱ as factorial experiment based on randomized complete block design with three replications. The experimental treatments consisted of mycorrhyza in two levels of inoculation and lack of inoculation and four rice cultivars (unknown, Ali Kazemi, Hasan Saraie and Tareme Hashemi). The results of analysis of variance showed highly significant difference in yiled and yiled components the number of seeds, height and length of the main panicule. Biological fertilizer inoculation lead to significant increase in yield and also yield components, so that  the highest yield has been related to the interaction treatment of anonymous cultivar  and mycorrhiza fungi and produced yield was more than ۶.۰۸ t/ha. In general the results of this experiment showed that fertilizering rice with mycorrhiza can lead to improving rice nutrition and this can increase yield and other agronomic traits of this plant.
