Water-Conserving Wheat Irrigation Schedules Based on Climatic Data

摘要

Irrigation schedules were developed based on correlations between yield and rainfall for the Oklahoma area. Historical records show that wheat yields are best when rain falls within a five day interval in late March. Past irrigation scheduling did not call for water applications to begin until after April 1. The records used to develop the correlations were for spring rainfall and grain yield on winter wheat grown between 1960 and 1977 at Stillwater and Goodwell, Oklahoma.
