Soybean plants have the ability to withstand a certain amount of stress, whether it be from diseases, insects or drought. However, plants can only withstand these pressures for so long before losing yield. Drought stress is no exception. For this reason, a significant number of Mississippi soybean farmers irrigate their soybean acres. Irrigation can substantially increase yield, but the practice does not come without additional costs and labor. Nevertheless, certain practices and tools can make irrigation more efficient and farmers more profitable. This document provides a variety of information on soybean water relations and its connnection to irrigation in the Mid-South.
