An Integrated Approach to Evaluating Crop Water Requirements and Irrigation Schedule for Optimizing Furrow Irrigation Design Parameters in Kurnool District, India

In Kurnool district, due to the hot, arid climatic conditions, proper study of crop evapotranspiration and its effect on water demand for various crops is an extremely important issue. More focus will be given design development surface irrigation systems based mostly furrow irrigation, as rainfall pattern this district was irregular in 2005. The requirement parameters optimising beneficial utilisation available resources field performances are studied research. Some major crops, such cotton, sugarcane, sorghum, maize, sunflower, considered when adopting a suitable system soil conditions types black clay, red loamy, medium loam. reference estimated 2005 Penman–Monteith equation per FAO guidelines by CROPWAT 8.0 model. Crop Water Requirement (CWR), Net Irrigation (NIR), Gross (GIR) were determined conditions. Soil characteristics using AQUACROP 6.1 compared with model accuracy. Various conservative non-conservative under limited set correlation equations developed between different parameters. Moreover, FURDEV (a module SURDEV model) three modes operation (i.e., fixed flow, cutback tailwater reuse method) modified SCS (Soil Conservation Service) families infiltration characteristics. NIR values 200 mm, 1423.2 220 150 mm respectively. A maximum significant dry yield observed maize (13.586 tonnes/ha). Additionally, application efficiency storage obtained at 95.5% sorghum 99.3% which would outcome general, results research might very effective authority District plan approaches designing developing management systems.
