Abstract: The study was carried out to estimate reference crop evapotranspiration, develop crop coefficient, area factors and estimates of pomegranate evapotranspiration for Pune region of Maharashtra. The crop coefficient values were estimated on weekly basis from the concept of shaded area approach that is widely used for the deciduous crops. Shaded area was estimated at 12.00-13.00 h with the help of specially prepared plywood board of different sizes with grid marking of size 20 x 20 cm for 5 randomly selected pomegranate trees each from 2 orchards of different ages. The values of water to be applied to pomegranate plantation spaced at 4.5 x 3 m and irrigated by the drip irrigation system of 90 % efficiency were estimated for 1st, 2nd, 3rd, 4th and 5th year of pomegranate orchard for Ambe Bahar, Mrig Bahar and Hasta Bahar. The values of water to be applied presented in this paper would be useful for the appropriate irrigation water management of pomegranate.
