Abstract
Zinc fertilization by broadcast, foliar, and seed‐row application methods were evaluated as a means to enhance sugar beet ( Beta vulgaris L.) production on a calcareous soil with marginal (0.5 to 1.0 ppm) Zn availability. Seed‐row‐applied ZnSO 4 (ZnSO 4 at 6 lb/acre, Zn at 2 lb/acre) resulted in the most consistent benefit to root yield over the three year study, resulting in an 11% (2.8 ton/acre) root yield increase compared to no Zn application. Broadcast and foliar applications of Zn plus B, Fe, and Mn produced lesser and more sporadic yield increases than did seed‐row‐applied ZnSO 4 . Placing the salt‐based ZnSO 4 in direct contact with seed did not appear to have inhibited seedling emergence; rather it enhanced the rate of emergence in two of the three years. There was evidence that seed‐row application of ZnSO 4 resulted in stronger and more vigorous seedlings than those obtained with other Zn application methods. Because this study was conducted at only a single location, additional research at other locations is necessary to validate results and justify changes to current guidelines.
