Abstract
Many soybean [ Glycine max (L.) Merr.] producers along the East Coast regularly inoculate their soybeans without knowing the yield benefit/loss or economic return. The objective of this research was to determine the soybean response (seed yield, plant height, lodging, and seed weight) to several commercial and experimental inoculants in land cropped with soybean at least once during the previous 3 yr. In 1987 and 1988, plots were established at 10 Coastal Plain environments in Virginia and North Carolina. Each of the following inoculant treatments were evaluated in replicated (4 to 8 reps/environment) plots in at least two environments: control, EXP‐48L, EXP‐504GP, EXP‐557V, EXP‐557VM (experimental inoculants from AS. Paau, Middleton, WI), and Soil Implant and ProTreat 3 (commercial inoculants from Nitragin Co., Milwaukee, WI). Various inoculant treatments were applied to 38 cultivars from maturity groups III to VIII. There were significant ( P < 0.10) differences among locations and among cultivars for seed yield, plant height, and seed weight. None of the inoculant treatments tested, however, were significantly different from the control for seed yield, plant height, lodging, or seed weight. In one of the 10 environments, some experimental inoculants significantly exceeded the control for seed yield, but the differences were less than 1 bu/acre. There was a significant cultivar × location interaction effect, but no cultivar × inoculant or inoculant × location interaction effects. The results from this study and from previous work done on inoculants from Louisiana and the Midwest suggest that a yield response to the addition of inoculants is unlikely where soybeans are regularly in the crop rotation. The use of soybean inoculants as insurance for good nodulation is not necessary and cannot be economically justified.
