Data were collected from 20 bottle gourd farmers, 30 brinjal farmers and 20 cucumber farmers by using purposive sampling method. The averages total cost per hectare were calculated at Tk. 4,12,713, Tk. 2,69,627 and Tk.2,56,258 for bottle gourd, brinjal and cucumber production.Net return per hectare was the highest for brinjal (Tk. 7,32,811) and the lowest for bottle gourd (Tk. 5,79,431).The benefit cost ratios (BCR) considering variable cost were 2.83, 4.88 and 4.57 for bottle gourd, brinjal and cucumber respectively. The highest BCR was for brinjal (3.72) and the lowest for bottle gourd (2.40) on the basis of total cost.
