A field experiment was conducted during 2006 and 2007 rainy season on a silty loam soil at Pusa, Bihar to study the effect of inorganic fertilizer in combination with organic sources, viz. vermicompost, poultry manure, FYM and green manuring under four dates of transplanting (5, 15, 25 July and 4 August) on rice ( Oryza sativa L.). Rice Rajendra Suwasani recorded significantly higher values of yield attributes (panicles/m2, panicle length, grains/ panicle, panicle weight, 1000-grains weight), yields and nutrient accumulation under integrated source of nutrients than inorganic fertilizer alone. Maximum grain yield (4.12 t/ha) was with 75% recommended dose of nitrogen (RDN) + 25% N from dhaincha ( Sesbania aculata L.) and it was 14.8 and 26.1% higher over 100 and 75% RDN, respectively. There was significant reduction in yield attributes, yields and nutrient uptake due to delayed trans- planting. Transplanting on 5 July recorded 13.6 and 25.3% higher grain yield than transplanting on 25 July and 4 August, respectively.References
