Field experiment was conducted at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirappalli to enhance productivity of sodic soil thorough bio intensive complementary cropping systems with organic amendments. The soil of the experiential field was alkali with pH: 8.8, EC: 0.96 ds/m and ESP: 17.1. The experiment was laid out in split plot design and replicated thrice. Main plot comprises three complementary cropping system ie. M1: Maize + Cowpea + Daincha, M2: Sunflower + Greengram + Daincha and M3: Bhendi + Onion + Daincha and sub plot comprises five treatment combinations like S1: 100% recommended NPK through fertilizers, S2: 50% recommended NPK through fertilizers + 50% N through FYM, S3: 75% recommended NPK through fertilizers + 25% N through FYM, S4: 50% recommended NPK through fertilizers + 50% N through poultry manure and S5: 75% recommended NPK through fertilizers + 25% N through poultry manure. Based on the results, it is concluded that complementary cropping of maize + cowpea + daincha with application of 75% recommended NPK through fertilizers + 25% N through poultry manure may be recommended for sodic soils for soil health improvement and obtained maximum economical benefits.
