A Simulation Program to Establish Optimum Crop Patterns on Irrigated Farms Based on Preseason Estimates of Water Supply

摘要: THIS paper describes a simulation program for digital computer that is designed to establish an optimum crop pattern on irrigated farms. The called PLAN make the most efficient use of predicted water supply throughout season in order derive highest net income. A basic part response soil moisture conditions, which varies individual crops over and among periods growth cycle. Schedules adequate conditions reductions yields result from missing specified irrigation turns are input data program. uses three decision points: organization allocates farms, irrigators farm managers decisions as what order. routine determines be grown each based its seasonal availability. results four runs using situations presented illustrate effects planning process acres under different expectations area incomes.
