ABSTRACT
A field experiment was conducted to study the integrated nutrient management practices on yield components and production efficiency of cotton and soybean intercropping system in 1:2 row proportion during kharif 2015 Dharwad. The field experiment was laid out in randomised complete block design with three replications and twenty treatments. Results revealed that all the yield components like number of bolls per plant, boll weight, seed cotton yield and cotton stalk yield in cotton and number of pods per plant, seed weight per plant, seed yield and haulm yield in soybean were higher under sole crop, followed by 150% RDF for cotton and soybean intercropping system. However, the land equivalent ratio (LER), area time equivalent ratio (ATER) and cotton equivalent yield (CEY) were higher in 125% RDF for cotton and soybean intercropping system, which was on par with 100% RDF for cotton and soybean + vermicompost 1.25 t ha-1 + gliricidia 2.5 t ha-1. These treatments proved most optimum for better use of growth resources in intercropping system.
Key words: Yield, LER, ATER, Cotton Equivalent Yield, RDF
