Author(s): BS Gunjal, HM Patil and SC Wadile
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. 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 (12.31 and 13.52 q ha-1) during both the years of rabi season experimentation. The experiment was conducted on same site without changing the randomization of the treatments for successive years.
