Experiment was done to study the integration of different sources of nitrogen and water management under vegetable based cropping system during rabi season of 2007 – 08 and 2008 – 09 at the Horticultural Research Station, Mondouri of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. The treatments consisted of three levels of irrigation as main plot viz., 15, 30 and 45 CPE, two cropping systems as subplot viz., sole crop and intercrop and three levels of fertility as sub-subplot viz., fertility level consisted of 100% N/ha from inorganic source, fertility level consisted of 75% N/ha from inorganic and 25% N/ha from organic sources and fertility level consisted of 50% N/ha from inorganic and 50% N/ha from organic sources. Tomato was grown as a main crop intercropped with French bean and radish. The recommended doses of fertilizer (RDF) were 120: 80: 80: N: P2O5: K2O kg/ha. Sole crop of tomato with 30 CPE level of irrigation and fertility level consisted of 75% N from inorganic and 25% N from organic sources was found to be the best combination with the production of 28.22 tonnes fruit per hectare. Irrigation at 45 CPE with fertility level containing of equal amount of inorganic and organic N produced highest yield of French bean (intercrop) with 8.04 t/ha. Treatment combination of 15 CPE level of irrigation along with fertility level consisted of 75% N from inorganic and 25% N from organic sources produced highest root yield (36.10 t/ha) of radish (intercrop). It was clear from the experiment that tomato as a sole crop together with application of irrigation of water at 30 CPE and fertility level consisted of 120 kg N (90 kg from inorganic source and 30 kg from organic source + 80 kg P2O5 + 80 kg K2O/ha had beneficial effect to boost up the yield.
