Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
and vegetables other than mustard. Collected run-off water helped farmers to pre-irrigate fields
for sowing of rabi crops when September rains were not received. This intervention
significantly increased in shallow acquirer level (2.5 to 4.0 m) and collected approximately
4000 cubic meters of rainwater which was continuously delivered in tube wells. Similar results
have been reported by earlier workers (Palanisami et al. 2006, Kambale et al. 2009, and
Honnannavar et al. 2016).

This low-cost tube-well recharge technology proved highly useful in decreasing irrigation
costs, and soil salinity due to improvement in groundwater quality. This successful intervention
has increased irrigated area as well as percent increase yield of 42.00, 35.20, and 45.50,
