Abstract

A long term experiment (1996-2001) was conducted for determining crop evapotranspiration (ETc) of tea (Thea sinensis) using weighing type lysimeter at the Central Soil and Water Conservation Research and Training Institute-Research Centre (CSWCRTI-RC), Research Farm, Udhagamandalm, Tamil Nadu, India. Based on the weekly average crop evapotranspiration for the entire period of observation, the different growth stages were observed and classified as initial season, mid season and late season for increasing growth rate, constant growth rate and declining growth rate, respectively. The average crop evapotranspiration for the corresponding s was 2.77, 3.31 and 2.27 mm/day, respectively. The maximum ETc was observed during mid season followed by initial and late seasons.
