Irrigating Soybeans (1993)

Abstract

Missouri's growing season is characterized by excessive moisture in the spring followed by inadequate moisture during the middle of the growing season. Because of the lack of moisture during the crops' peak demand, some producers have invested in irrigation systems. The cost of maintaining and using these systems is high, so it is imperative to manage moisture in the most efficient way possible. The following discussion should help Missouri soybean producers understand the crop's need, the soil's ability to hold and supply water, and the agronomic practices that can result in maximum economic yields under irrigation.
