A field experiment was conducted during Rabi season 2014-15 on ‘Vertisol’ in kymore plateau and Satpura hills Agro-climatic zone of Madhya Pradesh to study the effect of tillage and nutrient management on productivity and profitability of wheat (Triticum aestivum L.).Treatments comprising 4 tillage management (main plots) viz., conventional tillage(TM1), minimum tillage with broad bed furrow(TM2), minimum tillage with roto-seed drill (TM3) and zero tillage (TM4) and 6 nutrient management (sub-plots) viz., 100% RDF through inorganic fertilizer (NM1), 75% RDF inorganic+25% organic manure(NM2), 50% RDF inorganic+50% organic manure (NM3), 25% RDF inorganic+75% organic manure (NM4), 100% RDF through organic manure (NM5) and Control (NM6).The experiment was laid out in a Split plot design with 3 replications. Among tillage management treatments, significantly higher grain and straw yields, harvest index, Production efficiency and gross monetary returns (GMR) were registered under conventional tillage followed by zero tillage. However just reverse result was found in terms of net monetary returns and benefit: cost ratio. Similarly under nutrient management, treatments where 75% recommended inorganic fertilizer was applied along with+25% organic manure proved significantly superior over 25% RDF inorganic+75% organic manure, 100% organically treated plots and Control but found at par with 100% RDF through inorganic fertilizer and 50% RDF inorganic+50% organic manure in terms of grain and straw yields, harvest index, Production efficiency and gross monetary returns (GMR). However, maximum net monetary returns (NMR) and benefit: cost ratio were observed under 100% chemical fertilizers alone and followed by 75% RDF inorganic+25% organic manure treatments. Hence, the benefit: cost ratio of wheat was decreased with supplementation of recommended dose of fertilizer with increased rate of organic manures. But owing to the beneficial effect of organic manures on soil health, wheat can be grown under zero tillage condition with combined application of nutrient sources 75% RDF inorganic fertilizer+25% organic manure for getting higher production and net returns.
