| Long term field studies were conducted in the subhumid region of Mauritius on deficit irrigation practices to optimise use of limited water supply in sugar cane var. R570. Different irrigation regimes based on Penman potential evapotranspiration and crop factors were applied on a daily basis using drip irrigation. Cane and sugar yields together with climate and irrigation data were analysed after four years to establish an irrigation strategy that would optimise yields with respect to water availability. A linear programming approach was used to simulate the effects of different irrigation regime combinations on cane and sugar yields. Agronomic results showed a yield decline with reduced ifrrigation but the simulation exercise demonstrated that, with limited water supply, optimum yield would be achieved by irrigating a larger area at 0.50 ETc. Lowest yield would be obtained if all the water were to be concentrated on a small area at 1.0 ETc, with the remainder of the perimeter rainfed. These results are interesting enough to warrant further investigations in view of optimising cane water use in water deficient regions. | |
