Abstract:

Crop water requirement is the water required by the crop in a given period of time to meet its normal growth. PENMEN MONTEITH formula was chosen to calculate crop ETo for safflower crop from which crop water requirement is obtained. The period of 30 years meteorological data (i.e. from 1983 -2017) was collected from WALAMTARI (Water and Land Management Training and Research Institute) meteorological station and computerized. Solar radiation, crop duration, crop coefficient (kc) values for safflower crop and also sunshine hours was taken from a standard values available from FAO-56 tables, CRIDA, Hyderabad and standard textbooks. Then irrigation scheduling is done for safflower crop. GPS was used to calculate the field area of safflower and it was 0.24 ha. The total cropped area of safflower was divided into 6 plots, out of which 3 were irrigated by drip and 3 were by flood irrigation and each plot size was 1×1 m². The growth parameters like plant height, number of branches were noted to know the difference in growth between drip and flood irrigation. The study was concluded that the crop water requirement for safflower crop when estimated by Penman Monteith method was 365mm (Standard value is 250 to 300mm) for its entire crop period of 120-140 days in Rabi season. It was concluded that the yield of safflower under drip irrigation was 12.56 quintal and whereas in flood irrigation was 8.18 quintal. Thus 35% of yield was more in drip irrigation than flood irrigation.
