1. In-season Nitrogen Application Method Influence on Grain Sorghum Performance

Grain sorghum production in the United States is concentrated in the great plains. This region is prone too harsh environments that may provide opportunities for extensive N losses when relying on pre-plant N application alone. This problem may be alleviated through moving N application later in the growing season to optimize N availability when plant N uptake is most required to prevent yield loss. However, fertilizer application equipment availability may be limited for many producers in the... R.L. Sharry, B. Arnall
