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 P2O5 and 30 kg K2O/ha (recommended dose for white jute) along with MgSO4. 7H2O @ 10 kg/ha + lime (0.5 lime requirement) to jute crop recorded the highest fibre yield (2.28 tonnes/ha), and maximum grain yield (3.89 tonnes/ha) of succeeding rice crop were obtained with a fertilizer dose of 60 kg N, 30 kg P2O5 and 30 kg K2O/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 MgSO4. 7 H2O + 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 22,628/ha) and the highest benefit: cost ratio (1.71) were recorded with the recommended NPK to both crops along with MgSO4 and lime to jute only in jute-rice cropping system under rainfed condition.
