Topological Sustainability of Crop Water Requirements and Irrigation Scheduling of Some Main Crops Based on the Penman-Monteith Method

The following method was used to apply the topology of current study evapotranspiration ETo, net irrigation demand, schedules, and total effective rain fall different crop models: using Food Agriculture Organization's (FAO) CROPWAT 8.0 standard software CLIMWAT 2.0 tool FAO-56 Penman-Monteith approach examine variable ETo. Due high temperatures in summer with an annual mean 6.33 mm/day, topological demonstration reference (ETo) increases from 2.84 mm/day January a maximum 9.61 July. Effective rainfall fluctuates 0 mm 53.4 mm. Total indices requirements were 308.3 mm/dec, 335.9 343.6 853 1479.6 mm/dec for barley, wheat, maize, rice, citrus, respectively. physical due low demand winter summer, irrigation, gross clay loamy soils wheat (210.6 147.4 mm), barley (176.6 123.6 citrus (204.5 143.2 maize (163.9 114.7 but not rice. This demonstrates that has 4, 12, rice 12 schedules year.
