Studies were conducted to note the effect of season and crop rotation on yield, gross income, net profit and cost: benefit ratio as well as to identify suitable intensive and remunerative vegetable cropping sequence for Andaman island. The results indicated that during 1st season, i.e. December to April was the best season for all six crops in general and for tomato in particular which has gave maximum yield (355.96 q/ha), net profit Rs. 3,11,427 and cost: benefit ratio 1:6.99. The crop rotation, such as brinjal-cowpea-radish recorded the highest yield of 748.73 q/ha. gave Rs. 4,79,073/ha net return and cost: benefit ratio (1:4.16), followed by palak-bhindi-poi (701.86 q/ha, net return, Rs 4,06,609/ha and benefit: cost ratio, 1:3.38) per year respectively.
