Declining water table, indicative of overall negative groundwater balance has emerged as the most serious challenge to sustainability of irrigated agriculture in many states of India. It is resulting in reduced discharge from shallow wells and replacement of centrifugal with submersible purpose. It is more so in marginal ground water quality area such as Assandh block of Karnal district of Haryana, where deep semi-confined aquifers are of relatively good quality as compared to shallow aquifers. Ground water balance of the Assandh block, marginal water quality areas was assessed based on the net annual pumping from the ground water and net annual replenishable recharge. Even under the existing set-up, net annual replenishable recharge was negative and would result in lowering of water table by 80-90 cm annum-1. Temporal changes in pumped water quality revealed some increase in EC of the water of deeper aquifer . Studies revealed that water productivity was low under submersible than under centrifugal pump systems, mainly due to higher water application under the former situation. Under both the situations, pump efficiencies for selected centrifugal and submersible pumps were low ( ICAR-CSSRI |
