Abstract: Field experiments were conducted during boro seasons of 2004-05 and 2005-06 and kharif seasons of 2005 and 2006 at the Regional Research Station, New Alluvial Zone, Bidhan Chandra Krishi Viswavidyalaya, West Bengal to study the of comparative effect of manuring under farmerÂ’s practice, recommended practice and practice on the basis of soil test. Results revealed that manuring on the basis of soil test produced maximum grain yield (10.05 t ha-1 year-1), net return (Rs. 19,996 ha-1 year-1) and return per rupee investment (Rs. 1.51) under rice-rice cropping sequence. This was closely followed by the recommended practice. Soil nutrient status did not change much over initial value due to manuring in different system. On an average total nitrogen content decreased but available P and K content increased slightly..
