Maize in Bangladesh Third most important cereal after rice and wheat New crop: 3100 ha in 1990, 10000 ha in 1995, 202000 ha in 2009-2010 Mostly grown in cool winter Rabi season in North-west and central Bangladesh Expanding at approx 20% per year since early 1990s Production: Approx. 1.37 mill. ton in 2009-2010 Annual requirement: Approx. 2.5 mill. ton 24% maize area is covered by our own seed

  40. 40. Conclusion To keep pace with future demand of maize concurrently decreasing of cultivable land, vertical and horizontal expansion need to be taken through improving maize productivity. It needs to increase maize area in southern belt, hilly area, char land and in drought areas where thousands of hectares of land remain fallow during rabi and kharif seasons by adopting suitable variety.
