Effect of biofertilizer Barvar-2 and chemical phosphorus fertilizer application on kernel yield and yield components of maize (zea mays SC610) in Gorgan region

In order to investigate Effect of biofertilizerBarvar-2 and chemical phosphorus fertilizer application on kernel yield and yield components of maize (zea mays SC610) In 2014 pilot training and research in the field of Islamic Azad University of gorgan, Split plot in a randomized complete block design with four replications. Treatments included three levels of phosphorus fertilizer [Control (No fertilizer), 200 and 300 Kg/ha] as the main plot and bio-phosphorus fertilizer fertilized -2 at three levels [Control (No fertilizer), Seed treatment, Seed inoculation + topdressing] as a subplot. The results showed that the use of bio-fertilizer the traits Plant height, thousand grain weight and biological yield were significant. Fertilizer phosphorus on all mentioned traits except the Plant height, ear length and biological yield were significant. The highest grain yield in chemical phosphorus treatment 300 kg/ha to amount 3762 kg/ha Its difference with Control 3021 kg/ha Was significant. Interaction between treatments phosphorus fertilizer and bio-fertilizer on corn traits in plant height, thousand seed weight was significant. The highest grain yield in the interaction of biological fertilizer seed inoculation treatments + consumption chemical nitrogen and phosphorus 200 kg/ha With the performance 4107 kg/ha to themselves. The findings of this study indicate that organic fertilizers containing phosphorus can increase the absorption of phosphate solubilizing microorganisms from soil, leading to increased maize grain yield.
