A field research was undertaken to evaluate the comparative efficiency of Bio-power (a multi microbe) and nitrogen (N) chemical
fertilizer; alone and in combination on the growth, grain yield and N uptake of wheat. The chemical fertilizer was band incorporated
after sowing the crop. The experiment was laid out under Randomized Complete Block Design (RCBD) having 4 replications. The
seeds were treated with bio-fertilizer before sowing. Significant effect was recorded only on 1000 grain weight but all the treatments
performed at par except control. The treatment 100 kg N ha-1 resulted in 30.21 % increase in 1000 grain weight over control. Biopower alone or along with ½ recommended N @ 50 kg ha-1
or full recommended dose of N fertilizer and N chemical fertilizer did not
significantly affect grain yield, biomass and N uptake. Insignificant difference was established between bio-power and N chemical
fertilizer to have any effect on the growth, grain yield and N uptake in wheat. However, the maximum increase in grain yield and N
uptake was attained with 100 kg N ha-1
