A field study was conducted during rabi season of consecutive two years i.e. 2014-15 and 2015-16 at university farm at Bihar Agricultural University, to assess the effect of resources conservation practices and nutrient management on yield, yield attributes and economics under wheat crop. The experiment was laid out in split plot design, replicated thrice with three main plot viz. Conventional tillage, Conventional tillage + 30% rice residue incorporation, Zero tillage + 30% rice residue retention and four sub plot viz. 100% of Recommended dose of fertilizer (RDF) through inorganic sources, 75% of RDF through inorganic sources + 25% of RDF through organic sources (vermicompost), 50% of RDF through inorganic sources + 50% of RDF through organic sources (vermicompost) and 100% of RDF through inorganic sources + mungbean as green manuring. A preferential influence was found with the resources conservation practices. The results clearly indicated that the wheat crop under zero tillage +30% residue retention (M3) produced significantly higher grain (47.44 q ha-1) and straw yield (63.55 qha-1). Among the sub plot treatments 100% RDF + green manuring (S4) recorded more grain yield (46.33q ha-1) as compared to other treatments. It was statistically at par with 100% RDF through inorganic sources. Besides this, the superiority of resource conservation practices was observed over conventional practices in terms of cost saving (` 37565 ha-1) and more efficient use of inputs. Hence, zero tillage with 30% residue retention could be an economically viable option for wheat cultivation.
