With a continuous decline in seed protein concentration in U.S. soybeans, UNL researchers examined how irrigation practices in Nebraska may contribute to this issue for soybean growers.
Figure 1. In 2019 in York County (left), the grower built his own interseeder and tested a nitrogen mix (4 lb/ac crimson clover, 3 lb/ac red clover, 2 lb/ac yellow sweet clover, 4 lb/ac Winterhawk annual ryegrass, 1.5 lb/ac impact forage collards, 1.5 lb/ac Trophy rapeseed) vs. diversity mix (2 lb/ac red clover, 2.5 lb/ac Hubam white seed clover, 4 lb/ac Winterhawk annual ryegrass, 1 lb/ac purple top turnip, 3 lb/ac golden flax, 0.5 lb/ac phacelia Angelia, 0.5 lb/ac chicory) interseeded at V5-V6 corn vs. check treatment. Seward County (right), a Hagie was used to broadcast interseed 10 lb/ac red clover and 5 lb/ac buckwheat into V6 corn vs. check treatment.
