Role of Pulses in Sustaining Agricultural Productivity inthe Rainfed Rice-Fallow Lands of India in ChangingClimatic Scenario uri icon

abstract

  • With the growing recognition of the possibility of global climate change, an increasingemphasis on world food security in general and its regional impacts in particular have come toforefront of the scientific community. Agriculture production of rainfed regions is expected tosuffer severe water crisis due to delayed monsoon, uneven distribution of rain as a result ofclimate change. The impact of climate change on pulses appears to be more serious. It is mostunlikely that any additional area will be available for pulses cultivation in future, due to morereturns with cereals under irrigation and also due to shrinking land base for agriculture. However,about 12 million hectares remains fallow during the post-rainy season after harvest of rainyseason rice in the India and diverse soil types and climatic conditions of the rainfed rice fallowlands (RRFL) are suitable for growing both cool season and warm season pulses profitablyduring post rainy-season. The residual moisture left in the soil at the time of rice harvest will besufficient to raise a short-season pulse crops. Further, by use of short duration and highyielding varieties of rice allowing rice to vacate fields in September-October, the traditionalRRFL cropping can be converted into rice-pulses system. Inclusion of cool season and warmseason pulses such as chickpea, lentil, mungbean, urdbean, fababean, lathyrus, peas etc. inRRFL will increase the productivity as well as the sustainability of the rice. This paper discussesthe opportunities for the introduction of pulses and its expansion in RRFL with best bettechnological interventions of crop establishment, integrated crop management and need forpolicy support for their use as an integral part of daily diet and a source of income to millionsof resource poor farmers in the above regions
