Abstract :

The aim of this study was to investigate the effects of nitroxin and super nitro plus biofertilizers on morphological and agronomical characteristics of Maxima and 704 hybrid maize in Nizam Abad area of ​​Qazvin. This study was conducted as factorial in a randomized complete block design with 3 replications. Cultivar factor at 2 levels (H1: hybrid 704 and H2: maxima hybrid) and biofertilizer at 4 levels (B1: nitroxin, B2: super nitroplus, B3: nitroxin and super nitroplus, and B4: non-inoculated (control)) were considered. The results showed that the effect of biofertilizer and cultivar levels at 1% level on grain number per ear was significant. Nitroxin + Super Nitroplass treatment with mean of 788 seeds had the highest number of grain per ear and the lowest amount was observed in non-inoculated treatment. Maxima cultivar with mean of 796 seeds had a significant superiority to 704 cultivars. The results showed that the effect of biological fertilizer levels, cultivar and their interaction on grain yield was significant at 1% level. Comparison of the means of interaction between biofertilizer and cultivar levels on grain yield showed that Maxima cultivar with Nitroxin + Super Nitroplus and Super Nitroplus alone had the highest grain yield.
