Deepwater rice grown in Asia is a cultiver of Oryza sativa, probably evolved from perennial grass, Oryza rufipogon, via annual wild relative, Oryza nivara. There are more than 2, deepwater rice cultivars in Bangladesh and more than 6, in Asia. Almost all the deepwater cultivars are strongly photo-period sensitive. Rice varieties: Rice ( varieties): Binasail: It is a low input tall variety ( cm) released in , specially suitable for late transplantation after the flood water recedes which helps the rehabilitation of the people of flood prone areas. This variety File Size: 1MB. Rice yield also improved in the last decade, from a low of t/ha in to almost t/ha in These increases in rice yield and area harvested contributed to growth in rice production, which nearly doubled from over 26 million t in to 50 million t in Rice is the staple food of Bangladesh’s million people. Rice production in Bangladesh is a crucial part of the national economy. The dominant food crop of Bangladesh is rice, accounting for about 75 percent of agricultural land use (and 28 percent of GDP). Rice production increased every year in the s (through ) except FY , but the annual increases have generally been modest, barely keeping pace with the population.

A deep water rice variety evaluation is presented in this paper. Thirty-three varieties were sampled. It appeared that the varieties were largely zone-specific and strongly photoperiod sensitive; the mean yields of 6 exceeded 25 t/ha. The highest yields were associated with water depths of to m; late maturing varieties yielded less than medium and early maturing Author: H. D. Catling, P. R. Hobbs, B. Alam. About BRKB, Bangladesh Rice Knowledge Bank. A dynamic source of rice knowledge, rice production technology, a repository of rice knowledge, a hub of online rice and rice based technology informations. Replacement of deepwater rice (DWR) by modern rice in wetlands seriously impedes plant diversity and conservation in Bangladesh. Many DWR varieties have been lost and the remainders are in danger of extinction. Modern rice production has increased chemical fertilizers and pesticide uses. Rice in Bangladesh. Rice is the staple food of about million people of Bangladesh. It provides nearly 48% of rural employment, about two-third of total calorie supply and about one-half of the total protein intake of an average person in the country.

Welcome to Presentation on “Bangladesh perspectives on high yielding rice variety production for food security and experience-sharing on adoption of hybrid rice” Drought tolerance ScreeningRegional Seminar on Rice Production and Mechanization December ,Sanya, China Dr. ASM Masuduzzaman Principal Scientific Officer. major deepwater rice areas of Bangladesh carried out over a three-year period in the late s when deepwater rice was grown on more than two million hectares. This was the first time that the fauna of deepwater rice was systematically studied anywhere in Asia, and new field methods were developed to work in this deeply flooded environment.   AsianScientist (Oct. 12, ) – Farmers in drought-prone regions of Bangladesh can now look forward to a more bountiful rice harvest as the wet season ends and water becomes scarce, with two recently released drought-tolerant rice varieties: BRRI dhan56 and BRRI dhan Drought has been one of the biggest enemies of Bangladeshi farmers, so much so that the . Of them, 25 are varieties of Boro, 36 of Aman and 10 are Aush. In addition, Bangladesh Institute of Nuclear Agriculture (BINA) has developed another 18 rice varieties since its inception. Yet, statistics show that the most popular rice varieties among farmers are two Boro varieties – BRRI Dhan 28 and BRRI Dhan
