Abstract

An interactive computer program (SCHEDPEN) which utilizes growing-degree-day based crop coefficients for irrigation scheduling was developed and tested on cotton during 1988 and 1989 at two locations in Arizona. The program can directly accept weather data files from Arizona's automated agricultural weather station network (AZMET) via phone access. At both locations the program was compared to two other methods of irrigation scheduling and while yield and water use were not significantly different among the three methods, some algorithmic errors were found in SCHEDPEN which have been corrected. The program continues to be developed for additional crops and incorporation of additional management information.
