The present study was carried out to examine the impact of biofertilizers and nitrate salts on growth and physiology of maize crop during kharif 2009-2010 at precision farming development centre Indira Gandhi Krishi Vishwavidyalaya, Raipur. Experiment was conducted in split plot design comprising of three varieties (deshi, hybrid and composite) as a main plot while bio-fertilizers and nitrate salts combination in sub plot treatment. Observations were taken at specific growth phases of the crop and clearly indicated superiority of treatment 9 (50% fertilizer + Azospirillum + Calcium nitrate salts) exhibiting maximum leaf area index, treatment T5 recommended NPK showed maximum, relative growth rate and net assimilation rate but seed yield was recorded under the treatment 9 (50% fertilizer + Azospirillum + Calcium nitrate salts).
