Evaluation grain yield and quality of corn (MaximaCv) in responses to Nitroxin bioferilizer andc hemical fertilizers

ABSTRACT: In order to evaluate the effect of Nitroxin bioferilizer and chemical fertilizer on yield and yield components of Maxima corn, a randomized complete block design with factorial layout was conducted in an Agriculture Research farm in Shiraz, during 2010. The first factor included three levels of Nitroxin bioferilizer 0, 50 and 100 percentage of the recommended amount (1 liter of bioferilizer for 30 Kg of grain) and chemical fertilizer as the second factor included: no fertilizer (control), 200 Kg.ha -1 along whit 150 Kg.ha -1 and 400 Kg.ha -1 Urea along with 300 Kg.ha ammonium phosphate. The result indicated that Nitroxin bioferilizer and chemical fertilizers have significant impact on leaf chlorophyll at anthesis stage, 1000 grain weights grain and biological yield, harvest index, protein, soluble carbohydrate, K and Na content of seed. The highest values of these traits were obtained by using 100 percentage Nitroxin bioferilizer and the maximum chemical fertilizer. Bioferilizer and chemical fertilizer interaction affected significantly on leaf chlorophyll, 1000 grain weights grain, biological yield, soluble carbohydrate and K content of seed. The maximum biological yield was obtained by 100 percentages of bioferilizer and combination of 400 Kg.ha Urea with 300 kg.ha -1 ammonium phosphate. It seems the application of bioferilizer along with chemical fertilizer is robust method for constant production and environment pollutions reducing. -1 -1
