cover of ag water management guide Irrigation and water management information is housed on the Nebraska Extension website Water.unl.edu in the Agricultural Production section. Sub-sections include:

Also see the Agricultural Water Management Guide, a Nebraska Extension publication on irrigation management — both why it is used and more importantly, strategies to improve irrigation efficiency.  Also included are definitions of basic irrigation terminology and a brief history of irrigation. This publication is targeted to farmers, crop consultants, agriculture educators, science instructors, students, and anyone interested in increasing their knowledge of irrigation management.

Soybean pods
Figure 1. Soybean pods collected from stage R7 plants (one mature pod per plant) that were opened to determine if the pod wall interior membrane was still clinging tightly to the seeds (leftmost pod), or if it was beginning to detach from the seeds (second pod), or if the membrane was now permanently attached to the pod wall (third pod). After attaining physiological maturity, seeds undergo a dry-down period from about 60% moisture to about 13% moisture. Note that the Rx.x numbers used here are pod-based stages, not plant-based stages.

Understanding Ending Reproductive Stages in Soybean

August 27, 2021
The timing of the ending R stages in soybean is governed by planting date (PD) and varietal maturity group (MG), though the date of R7 can be hastened if water stress and high temperatures prevail in August — something we are seeing in portions of Nebraska this year.
