Abstract

Irrigation scheduling is rapidly gaining acceptance as a valuable tool for
developing an on-farm water management program. Irrigation scheduling
develops the optimum timing and amounts of irrigation applications and provides
the ability to manage the soil-moisture reservoir. Improving the
timing and amounts of irrigation applied will reduce the adverse environmental
effects of irrigated agriculture. Improved management of the soil-moisture
reservoir directly benefits the irrigator economically. A computer
is used to maintain a daily water budget, give the current status of the
soil-moisture reservoir, and predict evapotranspiration for the next 14 days.
Data required are basic soil-moisture properties, estimated rate of crop
development, and daily climatic data. By applying these parameters as
they individually and comprehensively relate to an irrigation project and the
local cultural practices, an optimum irrigation schedule can be developed.
This schedule gives attention to the many decision considerations that an
irrigator needs to make in his day-to-day operation.
