Abstract
A field experiment was carried out during the winter (rabi) season of 2020–21 on sandy clay loam soil of College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad, to study the effect of incorporation of cotton (Gossypium sp.) stalk on soil-fertility status and yield of succeeding sweet corn (Zea mays L.). The treatments comprised 2 levels of residue management, viz. shredded cotton stalks incorporation and no incorporation, and 5 fertility levels, viz. control, 75% Recommended dose of fertilizer (RDF), 100% RDF, 125% RDF and 150% RDF, making 10 treatment combinations. There was no significant impact of residue incorporation on yield and quality parameters of sweet corn over the residue removal but NPK uptake was enhanced with cotton-stalk incorporation. However, higher net returns and benefit : cost (B : C) ratio were obtained with residue removal plots. An application of 150% RDF (300 : 90 : 75 kg NPK/ha) resulted in the significant increase in yield and was at par with 125% RDF (250 : 75 : 62.5 kg NPK/ha). Quality parameter, viz. crude protein (11.6%), was higher with the application of 150% RDF, being at par with 125% RDF. The higher gross returns, net returns and B : C ratio were obtained with 150% RDF. It would be, therefore, advisable to apply 125% RDF (250 : 75 : 62.5 kg NPK/ha) to sweet corn. The interaction effect between residue management and fertility levels was non-significant for all the parameters of sweet corn.
