A field experiment was conducted at Kharagpur during 1991 and 1992 to study the effect of varying levels of N and P applied to capsularis jute (Corchorus capsularis L.) and their residual benefits to the succeeding rice (Olyza sativa L.) crop. Jute crop showed response up to N,, P,, level. Sizeable amount of jute biomass was recycled in soil through root stubbles (1,605 kglha) and leaf fall (387 kglha) supplying 23 kg IVIha and 10 kg P,O$ha. Advantage of residual .,.-- fertility to rice improved the grain yield significantly by direct application of chemical fertilizer at sub-optimal dose, i.e. N,, .P, Thus, a saving of 20 kg N/ha and 10 kg P,O$ha could be achieved due to residual fertility derived from jute biomass in jute-rice cropping sequence.References
