Due to lack of sufficient irrigation infrastructure and also access to water resources farmers helplessly see their crop drying up, often during flowering stage. The plot should be properly levelled and bunded. When large numbers of such pits are dug over a big patch of land say more than 20 hectares, general moisture regime of the patch increases. Impact varied from place to place depending upon some cultural factors. The technique has been studied under Indo-German Bilateral Project.
Findings are positive.
It needs further intensive study to get an in depth understanding about the potential of the technology.
