Appendix F
Basal Crop Coefficients for Crops Common to Temperate and Continental Climates
Publication: Evaporation, Evapotranspiration, and Irrigation Water Requirements
Abstract
This appendix presents the basal crop coefficients, , for crops common to temperate and continental climates for use with alfalfa reference , as computed by the American Society of Civil Engineers Standardized Penman-Monteith Reference Method using a growing-degree-day basis. Cumulative growing degree days (CGDD) provides automated flexure, expansion, or compression of the curve basis under varying weather conditions and eliminates the need to specify the time of effective full cover. The appendix describes the conversion and basis for applying CGDD. Automating the estimation of planting and greenup dates for crops is required to enable the computation process to operate for multiyear periods without manual intervention or specification of starting and ending dates for curves. Killing frosts can terminate growing seasons prematurely for crops that grow late into fall or for crops that are sensitive to light frost.
