RESPONSE OF SUGARCANE TO DIFFERENT LEVELS OF IRRIGATION UNDER HIGH WATER TABLE CONDITIONS

Abstract

Field trial conducted during the year 1980-81 and 1981-82 at Regional Sugarcane Research Station, Navsari on heavy black soils under high water table conditions having treatments of three levels of irrigation schedule based on IW:CPE ratio of 0.5 (R) 0.7 (R) and 0 9 (R,) during 1980-81 and four levels of irrigation scheduled at IW:CPE ratio of 0.3 (R.). 0.5 (R.), 0.7 (R) and 0.9 (R) during 1981-82, with four levels of nitrogen @100, 200, 300 and 400 kg N/ha. The results revealed not significant difference in the yield between the treatment R (10 to 11 irrigations) and R. (16 10 17 irrigations) in both the years as well as in pooled analysis. Further, on lowering the irrigation schedule in second year at an IW:CPE ratio of 0.3 (R.), the yield differences was not observed significant between the sixteen irrigation (R) and six irrigations (R.) indicating the sugarcane crop does not only need more than ten irrigations. Under a situation of high water table conditions, but also there is a possibility to reduce the number of irrigation up to six each of 80mm depth:
