Effect of Cotton Stalks Residues to Check Fertility Level of Soil, Yield and Energetics of Sweet Corn

Abstract

A field experiment on Impact of incorporation of shredded cotton stalks to influence soil fertility status along with production of succeeding sweet corn was organized at college farm, Rajendranagar, Hyderabad in the midst of rabi 2020-21. The demonstration was proportioned in Randomized Block Design (factorial) and replicated thrice. Treatments contain two residue management viz., Shredded cotton stalks incorporation and no incorporation and five levels of fertility levels viz., control, 75% RDF, 100% RDF, 125% RDF and 150% RDF (Recommended Dose of Fertilizer). Incorporation of cotton stalks did not significantly influenced the grain and fodder yield. Grain and Fodder yield was significantly higher in 125% RDF which was on par with 150% RDF. Incorporation of cotton stalks @ 5 t ha-1 (Residue management) before sowing of the succeeding sweet corn did not influence the energy ratio, energy productivity, productivity day-1. 125% RDF recorded higher energy ratio, energy productivity, while higher productivity day-1 was observed in 150% RDF.
