Compensating Nitrogen Fertilizer Requirement of desi Wheat by Vermicompost and Azotobacter

The aim of the present study was compensating nitrogen fertilizer requirement of desi wheat by vermicompost and Azotobacter. The experiment was conducted during the rabi season of 20172018 at the Agronomy Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar. The soil of the experimental field is sandy loam in texture, slightly alkaline in reaction, low in organic carbon and nitrogen, medium in available phosphorus and potassium. The experiment was laid out in Randomized Block Design replicated thrice with ten treatments viz. T1 (Control) , T2 (Vermicompost @ 6 t ha -1 ) , T3 (Azotobacter + Vermicompost @ 6 t ha -1 ), T4 (30 kg N ha -1 + Vermicompost @ 3 t ha -1 ), T5 (40 kg N ha -1 + Vermicompost @ 2 t ha -1 ), T6 (50 kg N ha -1 + Vermicompost @ 1 t ha -1 ), T7 (30 kg N ha -1 + Azotobacter + Vermicompost @ 3 t ha -1 ) , T8 (40 kg N ha -1 + Azotobacter + Vermicompost @ 2 t ha -1 ), T9 (50 kg N ha -1 + Azotobacter + Vermicompost @ 1 t ha -1 ) and T10 (60 kg N ha -1 ). Among various combinations of nitrogen fertilizer, vermicompost and Azotobacter treatments T10 recorded significantly higher yield attributing characters like number of grains per spike, number of spikelets per spike and spike length, grain, straw and biological yield of desi wheat. But various treatments failed to produce any significant variation in 1000 grain weight of desi wheat.
