Effect of Different Organic Manures, Green Manuring and Fertilizer Nitrogen on Yield and Uptake of Macro Nutrients by Chickpea in Vertisol

A field experiment was conducted to study the effect of different organic manures with different levels of inorganic fertilizer -N 50% N and 100% N Recommended dose of N (RDN) on grain yield and uptake of major nutrients (N,P,K) in Vertisol. The highest grain yield and uptake of NPK of chickpea were obtained where 50 percent N through subabul/ sunhemp plus 50 percent recommended dose of fertilizer N-was applied under subabul/ sunhemp as green manure.
