Abstract:
Bangladesh is an abode of 5,000 species of vascular plants and is the secondary centre of origin of a good number of crop plants. Evidence is mounting about the rapid wane of its genetic resources. The National Agricultural Research System (NARS) started cropping systems research as far back as in 1974 with a special focus on crop diversification. A number of potential cropping patterns have been identified. As a result cropping system is gradually transforming from traditional practices to improved management practices with improved varieties.
