Losses of water from rice field through evapotranspiration and percolation during different seasons under shallow water table conditions

Abstract

Experiments were conducted in tha tank irrigated wet lands of th3 University of Agricultural sciences. Bangalore to study the evapotranspiration (ET) and ET/E at different stages of crop growth in rice during different seasons under shallow water table conditions. In ths light of the results obtained, it may be concluded that the seasonal ET in rice rangod from 45.23 to 57.12 crn undortank irrigation with shallow submergence of 5 to 1 cm standing water in ths field. Water usa and ET were comoarativaly more in tha first half of crop growth. The ET/E ratio for ths crop season ranged from 0.76 to 1.06.
