Field experiment was conducted between 2002-2004 at Mohanpur, West Bengal to study the effect of inte- grated nutrient management (INM) on the growth, productivity and quality of crops in rice ( Or yza sativa L.) cab- bage ( Brassica olerecea var. capitata) greengram ( Vigna radiata L.R. Wilczek) cropping sequence under irri- gated ecosystem on an entisol. The experiment was laid out in RBD replicated thrice with 8 nutrient management treatments of different organic sources of nutrients in combination with inorganic sources. The highest productivity and quality of the crops in sequence and rice equivalent yield (32.4 tonne/ha) was observed with application of 75% recommended dose of fertilizer (RDF) along with 25% N through Neematex. Application of FYM or Biomax were also as good as the highest yield producing treatment. The highest net returns (Rs 1,43,463/ha) and net B:C ratio (2.92) were obtained when crops in sequence were fertilized with 75% RDF along with 25% N through FYM. Combined application of organic and inorganic sources of nutrients improved the nutrient uptake by the crops in sequence as compared to chemical fertilizer alone.
