Economics, evaluation of different sources and levels of organics for sustainable production under cereal- cereal cropping system in Maharashtra

摘要

A field experiment is being conducted since 1984 with integrated nutrient supply to sorghum- wheat system in vertisols to study, the contribution of organic manures to nitrogen economy and sustainability of soil fertility, and productivity with 12 treatments Viz. Control, 50 % RDF, 75 % RDF, 100 % RDF, 50 % RDF + 50 % N through FYM.,75 % RDF + 25 % N through FYM, 50 % RDF + 50 % WCS, 75 % RDF + 25 % N through WCS, 50 % RDF + 50 % N through green manuring, 75 % RDF + 25 % N through green manuring andlast is farmers practice (45 kg N :20 kg P_2O_5 kg/ha) in randomized block design with four replications.farm yard manure (0,54 % N),green manuring (Glyricidia 2.73 % N), wheat cut straw (0.46 % N) were incorporated into the soil before sowing of the cro
