Title of Presentation: Effect of Planting Date and Starter Fertilizer on Soybean Quality and Yield

Abstract: Variation in Ohio weather patterns has caused soybeans (Glycine max) to be planted early and late in the growing season. Date of planting has been the management decision known to have the largest impact on soybean yield. Starter fertilizer is usually not recommended for soybean production, however, some studies have shown that soybean yield and biomass have increased with the use of nitrogen fertilizer in cool, moist soil conditions. In Ohio, fields that have not been tilled in the spring prior to planting are typically cooler and wetter than those that have. Using starter fertilizer may be beneficial when nitrogen availability is minimal in these soil conditions. The effects of planting date and starter fertilizer interactions need to be tested in Ohio growing conditions. The objectives of this study are to (i) evaluate the effect of planting date and starter fertilizer on soybean canopy development, nodulation, grain quality, and yield; and (ii) determine the economic return of each planting date and starter fertilizer treatment. Earlier planted soybeans may be able to take advantage of starter fertilizer, which could increase above and below ground biomass. If biomass increases, canopy closure can occur sooner and yield potential can be maximized.
