Abstract

                                Field experiments were conducted at the Tamil Nadu Agricultural University, Coimbatore during 1991-92 and 1992-93 under irrigated conditions to identify suitable cotton based cropping system under Coimbatore conditions. Results revealed that cotton (MCU 5)-tomato (Co 3) gave a maximum net income of Rs.26,900 and Rs.33, 150 during 1991-92 and 1992-93 respectively. Cotton (MCU'S)- soybean (Co 1) and cotton (MCU 5) - maize (Col) systems also recorded more net income next to the cotton-tomato cropping system.
