孟加拉北部的库里格拉姆地区有222个字符(新开发的土地)，其中有23,000公顷耕地。本研究的目的是在喀里夫(夏季)地区引进绿豆和短时安曼水稻。这两种作物都于2013年在Kurigram Sadar和Nageshwary upazillas的30名农民的4公顷炭化土地上成功种植。为了在大量农民中推广这种模式，2014年在库里格拉姆地区的Kurigram Sadar、Nageshwary和BhurunGamari三个upazillas的8个木炭上种植了133.33公顷的绿豆和短期Aman水稻，涉及1,000名农民。然而，2014年4月，伴随着极端高温的严重干旱，绿豆受到了严重的破坏。Aman水稻于2014年7月20日至8月10日移栽。那年8月中旬发生洪水，并持续了三个多星期，严重破坏了稻米收成。有几项建议，如在小麦或马铃薯(冬季作物)之后种植的作物不应在绿豆上施肥，灌溉制度应根据干旱的强度和当时的气温设计，如果水稻作物完全淹没两周以上，可以考虑二次育苗床，这可能是从与农民和推广人员的讨论中提出的，以确保作物的成功生产。
The Kurigram district of northern Bangladesh has 222 chars (newly-developed lands), which have 23,000 ha cultivated lands. This study was initiated to introduce mungbean and short duration aman rice in the Kharif (summer) seasons in the chars. Both of these were grown successfully in 2013 on 4 ha of char land of 30 farmers in both Kurigram Sadar and Nageshwary upazillas. To introduce the pattern among large number of farmers, both mungbean and short duration aman rice were grown on 133.33 ha, involving 1,000 farmers on eight chars of three upazillas, namely Kurigram Sadar, Nageshwary and Bhurungamari of Kurigram district in 2014. However, there was serious drought concomitant with an extreme high temperature in April 2014 and the mungbeans were damaged seriously. Short duration aman rice was transplanted from 20 July to 10 August 2014. That year the flood appeared in mid-August and continued for more than three weeks, damaging the rice crop severely. Several recommendations, such as no fertilizers should be applied in mungbean if the crop is grown after wheat or potato (winter season crops), irrigation scheduling should be designed based on the intensity of drought and prevailing temperatures, a second-time seedbed, which may be called ‘backup’or ‘insured’seedbed, may be considered if the rice crop is totally submerged for more than two weeks, were made from the discussion meetings with farmers and extension personnel for successful crop production in the chars.
