How to save water in sugarcane by switching from flood to drip irrigation?

Drip can cut sugarcane water use by roughly 40 to 50 percent compared to flood while often raising yield because the root zone stays evenly moist. Use subsurface or surface drip with laterals along the cane rows, run fertigation through it so urea and potash go straight to the roots, and irrigate based on soil moisture rather than fixed days. You also save electricity and labour and weeds reduce between rows. Under PMKSY Per Drop More Crop, micro irrigation gets about 55 percent subsidy for small and marginal farmers and around 45 percent for others, with extra top up in some states, so apply through your agriculture or horticulture department. Get a proper design from a registered company for your slope and water quality.
