Abstract
The aim of this study was to evaluate the response of corn (Zea mays L.) grain yield to nitrogen (N) fertilizer application and its residual effect on soybean [Glycine max (L.) Merr.] seed yield. During the 2021 growing season, a corn-soybean rotation study was continued at Scandia, KS (USA), evaluating the effect of five N fertilizer rates (0, 53, 107, 161, and 214 lb N/a) applied in corn under both dryland and irrigated conditions. Average corn grain yields ranged from 124 to 147 bu/a for dryland, and from 159 to 203 bu/a for irrigated conditions. However, no significant grain yield response to fertilizer N rate was observed in either dryland or irrigated plots. Average soybean seed yields varied from 46 to 59 bu/a for dryland and from 76 to 86 bu/a for irrigated conditions. A significant effect of previous corn fertilizer N rate was observed under dryland conditions. Also, a significant positive soybean seed yield effect with corn maximum N rate (214 lb N/a) with respect to rates of 53 and 107 lb N/a. No residual effects of previous corn N rate were observed on soybean yields under irrigation.
