Using Historic Weather Data to Automatically Determine Length of Time for Crop Coefficient Growth PeriodsPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: 5th National Decennial Irrigation Conference Proceedings, 5-8 December 2010, Phoenix Convention Center, Phoenix, Arizona USA IRR10-9988.(doi:10.13031/2013.35840)Authors: Joseph C Henggeler Keywords: irrigation scheduling, modifying crop coefficients, plant height, canopy coverage, cardinal temperatures A computer irrigation scheduling program is no more accurate then the crop coefficient (Kc) values and corresponding coefficient curve being employed. The Kc values proffered by the widely accepted FAO-56 procedure were developed for regions with mild climates. In the cases where local weather conditions differ from these, FAO-56 provides straightforward methodologies to adjust those values. (Download PDF) (Export to EndNotes)
