Effect of Biofertilizers and Levels of Nitrogen on Productivity of Wheat (<i style="mso-bidi-font-style:normal">Triticum aestivum</i> L.)

74-79Data showed that inoculation of biofertilizers (Rhizobacteria, Azatobacter) significantly increased the growth and yield of wheat over uninoculated control during both the years. However. both the biofertilizer produced at par grain yield of wheat. Data also revealed that the maximum mean net return of Rs. 1477 I/ha was recorded from the application of Rhizobacteria. The mean grain yield of wheat (45.06 Q/ha) was recorded with 120 kg N/ha in respect of nitrogenous fertilizer during the experimentation. However. maximum nitrogen use efficiency of applied N was observed with 60 kg N/ha. It is evident from the data that the biofertilizer inoculation of wheat markedly increased the organic carbon and total N in soil over uninoculated control after wheat crop in both the years of stud
