The objective was to estimate the value of water used in the irrigation of citrus in the Central Ridge Section of Florida. Production functions were estimated to explain the relationship of irrigation water to citrus yields. Marginal value productivities were calculated from these estimated relationships. Two sources of data were used: yield and irrigation records for citrus plots at the Lake Alfred Agricultural Research and Education Center, and a citrus irrigation response study at Lake Alfred by R. C. J. Koo. Least-squares regression techniques were used to estimate response coefficients from yield data for the period of January, 1930, through June, 1956. The 1960-61 crop year through the 1967-68 crop year were used from the study made by Koo. Estimates of the marginal value of irrigation water per acre-inch for four selected time periods ranged from $7.23 to $148.39 for the plot data and from $6.51 to $20.64 for the study by Koo.
