"Food legume crops occupy about 5% of cropped area of Bangladesh but\r\nplay a significant role in rainfed agriculture. About a dozen legume crops\r\nare grown in Bangladesh of which khesari (lathyrus), lentil, chickpea,\r\nblack gram, mung bean are the major pulses, and groundnut is an oilseed\r\ncrop. Their cultivation is mainly concentrated in the Gangetic floodplain\r\narea. The productivity of these crops is much lower compared to the\r\ncereals, and compared to the potential productivity of these legumes, due\r\nto various biotic, abiotic, and socioeconomic constraints. Among the\r\nbiotic stresses, diseases, pests, seed dormancy, and weeds cause\r\nsignificant yield losses. The major diseases are botrytis gray mold,\r\nfusarium wilt, and collar rot in chickpea; foot rot, stemphylium blight,\r\nand rust in lentil; powdery mildew and downy mildew in khesari\r\n(lathyrus); yellow mosaic, cercospora leaf spot, and powdery mildew in\r\nblack gram and mung bean: and leaf spot, rust, foot rot, and root rot in\r\ngroundnut. Among the insect pests, Helicoverpa armigera is a major pest\r\nof chickpea and black gram; Diacrisia obliqua is a major pest of black\r\ngram, mung bean, and groundnut; aphids are common in lentil, khesari\r\n(lathyrus), and mung bean; Euchrysops cnejus, Monolepta signata, and\r\nBemisia tabaci are the major pests of mung bean and black gram. Among\r\nthe storage pests Callosobruchus chinensis infests all pulses except black\r\ngram, which is attacked only by C. maculatus. Lack of seed dormancy is\r\na major constraint in groundnut and mung bean cultivation. Weeds are a very common problem in all legume crops and in all growing zones.\r\nAmong the abiotic constraints, drought causes severe yield reduction in\r\nsome years. Sometimes excess rain and high humidity encourage\r\nvegetative growth, in turn leading to high disease and pest incidence and\r\nresultant yield loss. Terminal heat stress and rainfall also cause\r\nsubstantial yield loss. In some areas, micronutrient deficiency and soil\r\nacidity limit legume cultivation. Among the socioeconomic constraints,\r\nlow profit, instability of yield, and lack of support price influence the\r\nfarmers to follow the traditional practices for legume cultivation which\r\ninevitably result in poor yields. The area and production of these legume\r\ncrops are generally declining. The government has consequently launched\r\na Pilot Production Program on lentil, black gram, and mung bean to halt\r\nthe declining trend. Details of the constraints and the opportunities to fit\r\nthe legumes in new and diversified cropping systems in Bangladesh are\r\ndiscussed in this chapter."^^ . "2000" . . .
