Legumes in the Indo-Gangetic Plain of India uri icon

abstract

  • Cropping in the Indo-Gangetic Plain of India covering 44 million ha ispredominantly cereal based. Rice-wheat and rice-based cropping systemsare the most important systems, with rice-wheat rotations covering about10 million ha. Legumes account for about 5 million ha, which amounts toabout 14% of the total area in the country. This region has large spatialvariation in rainfall pattern (268 mm in the extreme north to 1600 mmin the extreme east), and is largely dominated by Inceptisol soils. There islarge variation in other agroclimatic characteristics such as temperatureregime, length of growing season, and evapotranspiration. Despite thislarge variation chickpea, lentil, and pigeonpea are cultivated as majorlegumes across the region. Their production in this diverse part of thecountry is severely constrained by a number of diseases, insect pests, andabiotic stresses. Socioeconomic constraints are also important indiscouraging their production. The Government of India increasedresearch outlay to develop improved technologies for increasing legumesproduction in the country. The results of Government investment werepromising, and a number of improved cultivars and technology optionswere developed to alleviate biotic and abiotic constraints. The Governmentalso initiated several policy measures to alleviate socioeconomicconstraints for increasing legumes production. The available trends showthat in some parts, legumes area is gradually increasing. The region showshuge potential for legumes production (either as a catch crop, summer crop,or sole crop in different cropping systems), provided appropriate cultivars/technologies reach farmers' fields
