Abstract
An experiment was conducted at an experimental farm in Giridih, India, to investigate the direct effect of organic and inorganic sources of nutrients on the production potential of upland rice (Oryza sativa L.) and to assess their residual effect on succeeding winter crops viz. linseed (Linum usitatissimum L.), niger (Guizotia abyssinica L.) and barley (Hordeum vulgare L.). The objective was to maximize the nutrient use efficiency and productivity of the cropping system in a sustainable way. The maximum grain yield, biomass production, and nitrogen (N) and phosphorus (P) uptake of rice were recorded when grown with the application of 100% NPK through fertilizers. Among the succeeding winter crops, linseed registered the maximum rice-equivalent yield. Irrespective of winter crops, 100% N supplied through vermicompost alone treatment recorded the highest value of rice-equivalent yield of winter crops. The maximum nutrient (NPK) uptake values were recorded for the cropping system grown under the treatment of 25% VC + 75% NPK supplied through fertilizers while the paddy-linseed system removed the maximum amount of nutrients from the soil. The paddy-barley system recorded the highest gross return, net return and benefit cost ratio.
