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. The experiment was laid out in a Randomized Block Design with three replications. The treatment consisted T1 – 100% GRDF, T2 - 75% RDN + 25% N through FYM, T3 - 75% RDN + 25% N through VC, T4 – 100% RDN + 25% N through FYM T5 -100% RDN + 25% N through VC, T6 – 125% RDN + 25% N through FYM and T7 – 125% RDN + 25% N through VC for kharif sweet corn as a main plot treatment, whereas for rabi potato two sub plot treatment levels of GRDF viz., F1 - 75 per cent GRDF and F2 - 100 per cent GRDF replicated two times in split plot design resulting in seven treatment combinations replicated thrice during kharif season and fourteen treatment combinations during rabi season in RBD-split plot design replicated thrice. The experiment was conducted on same site without changing the randomization of the treatments for successive years.Among 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.
