A field experiment was conducted at Agronomy Research Farm of N.D.U.A.&T. Kumarganj, Faizabad, during the Rabi season of 2012-13 to assess the growth, yield and nutrient availability as affected by integrated nutrient management of potato crop. The twelve treatments comprised with various levels of Tata Geo Green (as well matured compost prepared from byproducts of sugarcane industry) and Farm Yard Manure with 75% and 100% NPK fertilizers were tested against 100% fertilizers alone. Application of integrated use of Tata Geo Green @ 3.75 t/ha along with 75% recommended dose of NPK fertilizer (150:60:100) in potato was found superior for higher plant growth. The availability of N, P, K nutrients and organic carbon in soil increased at higher rate by applying TGG and FYM along with fertilizers as compared to chemical fertilizers alone. The application of Tata Geo Green @ 3.75 t/ha along with 75% recommended dose of chemical fertilizers provided highest net returns (Rs.133205) and Rs. /Re invested (1.34). It was concluded that application of TGG @ 3.75 with 75% RDF may be recommended for higher productivity and returns.
