Randomized trial estimates irrigation water requirements for major crops, suggesting improved scheduling methods.

The study aims to determine irrigation water requirements and scheduling for major crops in Hyderabad using the CROPWAT model.
Utilized the CROPWAT model for estimating crop water and irrigation requirements based on climatic, soil, and crop data.
Analyzed data for major crops including sugarcane, banana, cotton, and wheat over the growing season.
Evaluated the impact of rainfall on irrigation requirements during different growth stages.
Total CWR for sugarcane was 3,127.0 mm, while IWR was 2,964.0 mm.
CWR for banana was 2,012.3 mm and IWR was 1,966.7 mm; for cotton, CWR was 1,073.5 mm and IWR was 1,052.7 mm; for wheat, CWR was 418.9 mm and IWR was 407.6 mm.
Rainfall contribution varied: 163.0 mm for sugarcane, 45.6 mm for banana, 20.8 mm for cotton, and 11.3 mm for wheat.
