Abstract

The field studies on the effect of irrigation scheduling and N levels on water use, yield and quality of sugarcane ratoon during 1982-1983 and 1983-1984 revealed that irrigation scheduling and N fertilization significantly influenced the yield of ratoon. Maximum ratoon yield was obtained when the crop was applied irrigation at IW/CPE of 1.25 (CPE 60 mm) and fertilized with 200 kg.ha¹ of N. Increase in N application and frequency of irrigation increased consumptive use but decreased water use efficiency. Irrigation scheduling did not influence the juice quality but beyound 120 kg.ha' N the juice quality deteriorated.
