Abstract:

The crop water requirement (CWR) and irrigation requirement (IR) of rice crops were calculated using a web based software. Relevant crop coefficients (Kc), duration of crops and cropping pattern were used to calculate CWR from ETo. These coefficients present the relationship between references (ETo) and crop evapotranspiration (ET crop) or ET crop = Kc * ETo. The covered area of all crops (canopy cover) was collected. The Kc values were taken from FAO. The CWR were calculated for the north central plateau zone of Odisha for which climatic data were available and were applied to the nearest Research station. The effective rainfall was calculated with web based software by using FAO conversion table. The CWR and IR value was also calculated through this web based software Water requirement of summer crop like rice, is 920mm Irrigation requirement of this season rice is 845mm. and irrigation requirement of summer paddy is 844.98 mm. Water requirement of kharif paddy I (90 days), paddy II (120 days), paddy III(150 days), are 815mm, 940mm, 1200mm, respectively and irrigation requirement of kharif  paddy I (90) ,II (120)  &III (150) are 451.1mm,443.9mm and 634.6 mm respectively. By using the software a farmer of this zone can find out the water requirement and irrigation requirement by giving the crop name according to their season and duration of crop.
