Nutrient management in semi-deep water (30-50 cm) rice (Oryza sativa) and its effect on succeeding lentil (Lens culinaris) crop

An integrated use of farmyard manure with fertilizer gave significantly max imum average grain yield (3.34 tonnes/ha) of rice (Oryza sativa L.) and (1. 02 tonnes/ha) of lentil (Lens culinaris Medikus) during 1995-98. Applicatio n of neem cake-coated urea + P and K to rice resulted in significantly high er yields and uptake of nutrients by rice and succeeding lentil compared wi th rest of the treatments except integrated use of both, and farmyard manur e alone for lentil yield. Soil fertility (N, P and organic carbon) was impr oved significantly with FYM used either alone or in combination with fertil izer over that of initial soil status. Potassium content in soil was reduce d in all treatments.
