Future disseminationThrough dialogue and experimentation with farmers, a consensus has evolved: Thousands <strong>of</strong> farmers (>10,000) who have been exposed to this technologyare now convinced that a second crop, for example, chickpea (other rabicrops such as lentil, lintel, mustard, wheat, etc., need to be tested) after rice,can be grown without irrigation. An effective approach to dissemination has emerged. For new villages, thisincludes– Identification <strong>of</strong> interested and committed farmers and the formation <strong>of</strong>growers’ groups. The groups must agree to plant in a block to facilitatecrop protection.– Provision <strong>of</strong> training on crop production technology (as given above)to group representatives and village-level extension staff.– Provision <strong>of</strong> 200–300 kg <strong>of</strong> seed <strong>of</strong> short-duration chickpea varieties.Currently, only ICCV 2, KAK 2, and JGK 1 are available, but additionalvarieties are being developed using farmer participatory breeding approaches.– Provision <strong>of</strong> “starter packs” (enough Rhizobium inoculum, sodiummolybdate, and single superphosphate for 200–300 kg <strong>of</strong> seeds, i.e.,about 2–3 ha). Assembly and distribution <strong>of</strong> packs <strong>of</strong> Rhizobium andsodium molybdate represent an opportunity for small-scale businessdevelopment in resource-poor communities.– Technical backstopping where necessary.ConclusionsRainfed rabi cropping in rice fallow areas increases income and improves food securityand human nutrition. In many instances, it also improves social organization,agricultural skills, general empowerment, and commitment to the land. According toSingh (2002), “Rainfed areas have the highest concentration <strong>of</strong> poor and malnourishedpeople as these areas are characterized by low agricultural productivity, highnatural resource degradation, limited access to infrastructure and markets, and othersocioeconomic constraints…. There is evidence to suggest that investment in lessfavoredareas can yield relatively high rates <strong>of</strong> economic returns and significantlyreduce poverty and environmental and natural resource degradation.” We believe thatinvestment in promoting rainfed rabi cropping in these five states <strong>of</strong> India is a soundand productive avenue for poverty reduction and rural development and should bepursued more widely.ReferencesCSD (United Nations Commission on Sustainable Development). 2000.
