Comparative effect of manuring on yield, under farmers’ practice, recommended practice and practice on the basis of soil test under rice-rice cropping system was studied at Regional Research Sub-Station, Bidhan Chandra Krishi Viswavidyalaya, West Bengal. The results revealed that the highest growth, yield attributes, grain and straw yield (4.15 and 4.61 t ha^-1 during wet season and 5.90 and 6.10 t ha^-1 during boro season) as well as system productivity (10.05 t ha^-1) were recorded when the crop received 100 % recommended doses of NPK on the basis of soil test along with Zn @ 20 kg ZnSO₄ ha^-1 during both the seasons resulting in 53.90 % yield increase over control. This treatment also gave the highest value of net return (Rs. 25730 ha^-1) and return per rupee investment (1.70). Thus a nutrient management system can be adopted for sustained crop production, which involved nutrient application on the basis of soil test along with micronutrient application in the deficient soil.
