Abstract :

To study the effects of bio fertilizers and Nano zinc and their interactions on yield and yield components, this survey was conducted as factorial based on randomized complete block design with three replications in 2013 at Natural Resource Research Institute in Damavand city. In this experiment factors including biological fertilizer and chemical fertilizers at four levels including control or without the use of chemical and bio fertilizers, bio fertilizers application only(Nitragin),applying chemical fertilizers(100%dose) recommended based on soil test, chemical fertilizer(75%dose) recommended based on soil test and bio fertilizers (Nitragin) application and zinc fertilizer treatment including three levels control or no application zinc ,application of chelated zinc and application of Nano zinc respectively. The results showed the impact of bio fertilizers combined with chemical fertilizer was significant in all traits. Between chemical and bio fertilizers levels, 75% chemical fertilizer + nitragin had the highest number of seeds per row, grain yield and biological yield and had the greatest impact than the other levels. The results showed the impact of zinc fertilizer on the number of rows, grain yield and biological yield was significant. Also interaction effects of treatments on number of seeds per row and biological yield were significant. The results of this study indicate that the use of bio fertilizers in combination with chemical fertilizers on improve the yield and yield components of maize and also in order to sustain production and environmental protection had a positive impact and it seems bio fertilizers are a suitable alternative for chemical fertilizers.
