| Abstract | The objective of this study was to estimate monthly water consumptive use (CU) by sugarcane, from January through December, for four regional sites in Puerto Rico. Temperature and rainfall data", a USDA-SCS computer program, and information from USDA-SCS Technical Release 21 were used to estimate monthly CU with the following relationship; CU = K x kt x H x p x (0.046 x T + 0.8128) ill where, kc = a crop growth coefficient reflecting growth stage; kt = a climatic coefficient which is related to mean air temperature; p = monthly percentage of total annual daylight hours; T = mean air temperature (°C); and H = a humid area factor 0.8. K<. was 0.59 in April, 0.77 in May, 0.93 in June, 1.02 in July, 1.06 in August, 1.09 in September, 1.10 in October, 1.09 in November, 1.05 in December, 0.96 in January, 0.79 in February and 0.73 in March. The average Ke for the growing period was 0.84. It was assumed that sugarcane is planted 1 April and harvested 31 March. Four Agricultural Experiment Substations of the University of Puerto Rico were Fortuna, Gurabo, Isabela and Lajas. These sites correspond to distinct climatic zones of Puerto Rico.
