1 This document shows in a practical way the use of CROPWAT for design and management of irrigation schemes, taking the user, with the help of an actual data set, through the different steps required to calculate evapotranspiration, crop water requirements, scheme Estimated Reading Time: 14 mins. Apart from a completely redesigned user interface, CROPWAT for Windows includes a host of updated and new features, including: monthly, decade and daily input of climatic data for calculation of reference evapotranspiration (ETo). CROPWAT (Fixed percentage, Dependable rain, Empirical formula, USDA Soil Conservation Service). •In general, the efficiency of rainfall will decrease with increasing rainfall. For most rainfall values below mm/month, the efficiency will be approximately 80%. Unless more detailed information is available for localFile Size: 1MB.
Like CROPWAT , this software, as shown in Figure 16, permits user to set timing and amount of irrigation crop-wise. Figure 16 When How Much to Irrigate Two screenshots that follow this paragraph in Figure 17 18 underline the impact of alteration in irrigation scheduling. ET c during different crop seasons were calculated by the CROPWAT recommended by the FAO. The CROPWAT algorithms are based on the recommendation methods proposed by FAO in the publication No of the Irrigation and Drainage Series of "Crop Evapotranspiration - Guidelines for computing crop water requirements". CROPWAT is a Windows program based on the previous DOS versions. Apart from a completely redesigned user interface, CROPWAT for Windows includes a host of updated and new features, including: monthly, decade and daily input of climatic data for calculation of reference evapotranspiration (ETo).

CROPWAT 8 is a computer program developed by FAO that can calculate crop and. irrigation water requirements and irrigation scheduling from climatic, soil and crop data. (Swennenhuis, et al, ). The program is interactive in nature and can execute the.
