Author(s):

Kumari Namrata and Dr. Ravish Chandra

Abstract:
Water scarcity has become a constrained to attain goals of food security and sustainable natural resource management. In this study, experiments were conducted to determine water productivity, land productivity, process depletion and deep percolation losses of three different varieties of rice namely Turanta, RAU1428, Boro-3 in Pusa Farm of Dr. Rajendra Prasad Central Agricultural University, Bihar for kharif 2009 season. The water productivity values for gross inflow ranges from 0.10 kg/m3 to 0.14 kg/m3. The value of irrigation water productivity was 0.26 kg/m3 for Boro-3, followed by 0.21 kg/m3for Turanta and then 0.16 kg/m3 for RAU-1428.It was revealed that the crop water requirement was lowest for Turanta and highest for RAU1428 and deep percolation losses range from 70 -74 %. (Low water use Efficiency).
