The effect of phosphate solubilizing bacteria in combination with phosphorus fertilizer on yield of corn hybrids in the northern of Khuzestan
Abstract
In order to study the effect of phosphate solubilizing bacteria in combination with phosphorus fertilizer on yield of corn hybrids, the experiment was carried out in the north of Khuzestan province during the summer of 2013-2014 by a split plot design in the form of randomized complete block with four replications. Combining biological and chemical fertilizers as main factors at four levels (100% chemical fertilizer, 75%, 50% and 25% chemical fertilizer combined with 100% bio-fertilizer) were used in the main plots and corn hybrids pellets with three levels (S.C 704, S.C Mobin, S.C Karoon) were used in sub plots. In this study the combination of chemical fertilizer with biofertilizer had a significant effect on biological yield at 5% level while the other traits were not significant. Also, the hybrid type had a significant effect on yield components; however, the harvest index was not significant. It seems that combination of chemical fertilizer with biofertilizer was able to increase the performance of single cross hybrids and cross hybrids 704 and Karun while Mobin hybrid showed a lower capability for fertilizer.
