Abstract:
A field experiment on effect of incorporation of cotton stalk on soil fertility status and yield of succeeding sweet corn was conducted at Professor Jayashankar Telangana State Agriculture University, Rajendranagar, Hyderabad during rabi 2020-21. The experiment was laid out in randomized complete block design with factorial concept and replicated thrice. The treatments comprise of two residue management viz. cotton stalks incorporation and no incorporation and five levels of fertility levels viz. control, 75% RDF, 100% RDF, 125% RDF and 150% RDF. There was no significant impact of residue incorporation on growth characters over the residue removal. 150% RDF resulted in significant increase in growth parameters like plant height, number of leaves plant^-1, LAI, SPAD meter reading, dry matter production but at par with 125% RDF. It would be therefore, advisable to apply 125% RDF (250:75:62.5 kg NPK ha^-1) to sweet corn.
