Abstract: An experiment entitled “Effect of integrated nutrient management in sweet corn-potato cropping sequence" was conducted during kharif and rabi season of 2014 to 2015 at Instructional Research Farm, Central Campus, Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri. Results revealed that the application of the INM treatments, the various fertilizer levels to preceding sweet corn crop significantly influenced T7 - 125% RDN + 25% N through VC was found superior in growth attributes of sweet corn viz., plant height, number of leaves plant-1, leaf area and dry matter plant-1 at all crop growth stages of sweet corn during both the years of kharif season. The treatment T7- 125% RDN + 25% N through VC recorded significantly higher values of all yield contributing characters of sweet corn viz., length of cob with husk, girth of cob with husk, length of cob without husk, girth of cob without husk, weight of cob plant-1, weight of cob without husk cob-1, weight of husk, weight of grains cob-1, number of grain lines cob-1, number of grain lines-1, number of grains cob-1, weight of shelled cob during both the years of investigation. The maximum and significantly higher green cob yield, green fodder yield, biological yield and harvest index of sweet corn was observed in treatment T7 – 125% RDN + 25% N through VC. On the residual fertility of FYM (100% GRDF) potato plant recorded the highest plant height, LAI, number of haulms and DMA in haulms. Among the INM treatments, the various fertilizer levels to preceding sweet corn crop significantly influenced T1 - 100% GRDF was found superior in growth attributes of potato viz., plant height, number of leaves plant-1, leaf area and dry matter plant-1 at all crop growth stages of potato during both the years of experimentation. The various fertilizer levels to preceding sweet corn crop significantly influenced T1 - 100% GRDF was found superior in yield attributes of potato viz., medium tubers, big tubers, total tubers, weight of tubers per plant. The various fertilizer levels to preceding sweet corn crop significantly influenced T1 - 100% GRDF was found superior in tuber yield (280.21 and 286.96 q ha-1) and haulm yield (12.31and 13.52 q ha-1) during both the years of rabi season experimentation.
