A field experiment was conducted to study the direct effect of organic manures (sewage sludge, vermicompost and sesbania) and chemical fertilizers on rice and their residual effect on wheat grown in sequence during 2013-14 at Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. Among the nutrient sources, highest grain yield of rice (4.22 t ha-1) and wheat (3.55 t ha-1), system productivity (25.02 kg-1day-1), system profitability (251.91 Rs-1day-1), rice equivalent yield (80.62 q ha-1) and economics were recorded with 100% recommended dose of fertilizer (RDF) along with S40 kg, Zn5 kg and B1.5 kg ha-1 (T3) followed by customized fertilizer (T4). Lower yield and economics was recorded in control (T1). The use of organics amendment such as sewage sludge, vermicompost and sesbania along with chemical fertilizer were found to supplement 25% RDF along with significant increase of P in post harvest soil of rice and N and P in post harvest of wheat.
