Abstract:
As the current farming system is heavily reliant on chemical fertilizers, which negatively affect crop growth and crop productivity. Improving crop production on a sustainable basis is a challenging issue in the present agricultural system. To address this issue, a field experiment was conducted during Rabi 2020 at Crop Research Farm of Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj to know the interaction effect on assessment of Inorganic Fertilizer and Organic Manure on growth, yield and economics of Wheat. The experiment consisted of 9 treatments which includes 3 levels of inorganic fertilizer (0, 50 and 100%) and 3 levels of organic manure (0, 50 and 100%). The treatment T9 receiving @ 100% (NPK + Zn) + @ 100% FYM produced significantly higher plant height (113.76cm), length of spike (12.13cm), number of grains per spike (84.73), grain weight per spike (5.83g), test weight (44g), grain yield (8.16 t ha-1) and straw yield (7.85 t ha-1). However, Gross Return (199367.5 ₹ ha-1), Net return (131827.1 ₹ ha-1) and B:C ratio (1.95:1) was also obtained maximum with the application of T9 @ 100% (NPK + Zn) + @ 100% FYM. This experiment reveals that treatment T9 receiving @ 100% (NPK + Zn) + @ 100% FYM provides a sustainable nutrient management strategy to improve crop yield with high economic returns.
