irrigations ranges from 30 to 36; while in the subtropics 5 to 10
irrigations are required with a depth of 80 mm. The water
requirement of sugarcane in India varies widely from 1143 to
3048mm(Hapase et al., 1990). In Maharastra where the annual
rainfall is about 500 mm, the water requirement of sugarcane
varies from 2400 to 3000mm for the suru crop (12 months
duration) and 3200 to 3500mm for the adsali crop (16–18
months duration).
