Abstract

The field experiment was conducted during rabi season of 2011-12 and 2012-13 C.S. Azad University of Agriculture and Technology, Kanpur with the objectives to find out the combined effect of organic and inorganic fertilizers on grain yield, productivity and profitability of wheat crop. The 10 treatments were tested in Randomized Block Design with three replication. T1- Control, T2 - RDF (150:60:40 NPK Kg/ha), T3 - 125% RDF, T4 - RDF + Vermicompost @ 2.5 t/ha, T5 - RDF + Vermicompost @ 5 t/ha, T6 - RDF + FYM @ 5t/ ha, T7 - RDF + FYM @ 10 t/ha, T8 - RDF + Vermicompost @ 2.5 t/ha + Azotobacter, T9 - RDF + FYM @ 5t/ha + Azotobacter, and T10 - RDF + Vermicompost @ 2.5 t/ha + FYM @ 5 t/ha + Azotobacter. Result showed that the treatment T10 produced higher yield attributes and grain yield than rest of the treatment. The higher yield led to higher NPK uptake by wheat. Further, the available NPK and Organic Carbon (%) content of soil also increased in above integration of organic and inorganic fertilizer along with bio-fertilizer strain over control as well as chemical fertilizers alone. The highest net return (INR/ha 53882) and benefit : cost (1.23) was also obtained from the application of RDF + Vermicompost @ 2.5 t/ha + FYM @ 5 t/ha + Azotobacter and lowest from control (21873) and (0.74), respectively.
