Abstract: An experiment was conducted at Mahatma Phule Krishi Vidyapeeth (MPKV), Rahuri a representative place for the vertisols of Deccan plateau of India to study the effect of integrated nutrient management in sweet corn-potato cropping sequence on crop yield and soil physical, chemical and biological properties in the sweet corn-potato cropping sequence. There were seven treatments applied sweet corn and each plot of rabi potato was equally divided into two parts to potato. Results revealed that the application of the INM treatments, the various fertilizer levels to preceding sweet corn crop T7 - 125% RDN + 25% N through VC significantly higher cob yield in sweet corn, however it was at par T6 – 125% RDN + 25% N through FYM. Potato registered significantly higher tuber yield and sweet corn equivalent yield in residual fertility of 100% GRDF to preceding sweet corn, however it was at par with in T6 – 125% RDN + 25% N through FYM. The soil physical, chemical and biological properties determined at the end of two crop cycles were improved due to the application of FYM in combination with chemical fertilizers. The data recorded for two years indicated that available nutrient (N, P and K) under integrated nutrient management in kharif sweet corn and rabi potato during both years was significantly increased as influenced by 100% GRDF to preceding sweet corn in the main plot, 100% GRDF to rabi potato in the subplot while interactions showed non significant differences concerning the previous parameters.
