Abstract

Field experiments were conducted during the summer season of 1994 and 1995 at Cotton Research Station, Srivilliputtur to study the effect of intercropping and foliar nutrition on the productivity of summer irrigated cotton. Cotton + blackgram raised in paired row system (2:1) produced higher mean seed cotton yield equivalent (1815 kg/ha), mean net return (Rs. 17,724/ha) and mean benefit cost ratio (1.96). Spraying DAP two per cent + KCI one per cent (1:1) solution was found more economical. Raising cotton + blackgram in paired row 2:1 ratio and spraying DAP two per cent + KCI one per cent (1:1) solution resulted in the highest net return of Rs. 20,225 and benefit cost ratio of 2.12.
