Farming in Bhal region of Gujarat, India is dependent on vagaries of monsoon as the sources of irrigation water are limited. Topography of land is slightly concave with poor drainage. The soil infiltration rate varies from 0.04 to 0.19 cm per h, whereas, hydraulic conductivity of heavy black clay is very poor (0.012 cm per h). The soil profile shows upper 1.0 to 1.5 m layer of clay soil while beneath 4 m layer of silty loam. The water bearing strata at a depth of 4.5 m is observed at 6 m from the ground surface and has limited quantity of usable water. However, adequate water for irrigation as well as for domestic use is available at 31 to 36 m depth from ground surface. The average rainfall of 650 mm is not adequate to meet the requirement of crops grown in the region. Further, the crop production is affected due to the occurrence of dry spells (15 to 60 days) in the region. To mitigate the effect of dry spells/drought condition, supplementation of moisture through lift irrigation is the only way. Survey conducted in respect of command area by each bore well is indicative of 5 to 20 acres irrigated crops, viz., cotton, wheat and cumin [Cuminum cyminum]. The increment in cotton yield ranged from 30 to 50% with one supplementary irrigation of 6 cm depth. Wheat is a traditional crop grown on conserved soil moisture, but one irrigation at CRI or tillering stage increased 40% grain yield on farmer's field. New cash crop of cumin has been introduced in the area to insure high returns using bore well water. With 3 to 4 light irrigations, the farmers obtain 500 to 1000 kg/ha seed yield of cumin. Thus, to sustain and improve socio-economics in water scarce areas, lift irrigation has a better scope.
