| dc.description | Crop production in Bangladesh is focused mainly on rice production; where 79.4% land
area under this crop produced 28.849 million tons in 2007-08 (BBS, 2008). To increase
productivity in agricultural and non-farm activities, the development of small and
medium enterprises with specific focus on the promotion of agro-based industries, the
diversification of agricultural production into higher value crop chains such as fruits and
vegetables, all of which imply the promotion of a knowledge-based, high-tech
agriculture. | en_US |
