The scientists wanted to see how different amounts of water used for drip irrigation affect the growth of sugarcane plants. They tested three levels of irrigation and compared them to a control with no watering. By analyzing different plant traits and factors like rainfall and evaporation, they found that the sugarcane plants benefited the most when they were irrigated with 1.00 times the amount of water that evaporated from the canopy surface. This helped the plants grow taller, produce more stalks, and had a higher sugar content. The irrigation method they recommended led to higher crop yields and water use efficiency compared to other irrigation amounts tested. In conclusion, using the right amount of water for drip irrigation on sugarcane crops can improve their growth and productivity.
