Per hectare gross cost of Ash gourd production in farmers field found to be Tk. 52140 and
Tk 50317, while net return above cash cost and full cost were 44789, 51553 and 27460,
Tk 33283 in Gazipur and Hathazari, respectively. The study indicated that selected factors
of production have sufficient impact on Ash gourd production. It also revealed that farmers
allocated inputs for Ahs gourd production inefficiently. The farmers used inputs excessively
and some inputs were underutilized so that there was ample opportunity to increase
production by reorganizing and using all the factors of production efficiently. |
