A field experiment was carried out during 2000-01 to 2002-03, at Kendrapara, to study the effect of nutrient management on yield, nutrient uptake and economics of white jute (Corchorus capsularis L.)-rice (Oryza sativa L.) cropping system in rainfed medium land. Application of 60 kg N, 30 kg P20, and 30 kg K,O/ha (recommended dose for white jute) along with MgSO,. 7H20 @ 10 kglha + lime (0.5 lime requirement ) to jute crop recorded the highest fibre yield (2.28 tonneslha), and maximum grain yield (3.89 tonneslha) of succeeding rice crop were ob- tained with a fertilizer dose of 60 kg N, 30 kg P20, and 30 kg K20/ha in the system. This resulted in an increased yield of 26.7% in jute fibre and 10.2% of rice grain over the recommended fertilizer dose in both the crops. The nutrient uptake (N,P,K, Ca, Mg and S) of individual crop and the system increased owing to NPK + 10 kg MgSO,. 7 H20 + lime (0.5 lime requirement) in jute, followed by rice with only recommended fertilizer dose in comparison to other treatments. The maximum net returns (Rs 22,628lha) and the highest benefit : cost ratio (1.71) were re- corded with the recommended NPK to both crops along with MgSO, and lime to jute only in jute-rice cropping system under rainfed condition.References
