Nitrogen fertilization can improve biomass yield and nutritive values of forages, however little research has considered the influence of split spring and fall N applications on pasture productivity. Experiments were conducted at two different locations within the Ridge and Valley of Virginia to evaluate the effect of split N application at different rates on pasture biomass yield and nutritive values. Treatments consisted of seven N rates (0, 46, 92, 138, 185, 231, and 277 kg N ha^-1) that were split applied each fall and early spring. Plots were then harvested the following May. Our preliminary data indicated that both N rate and time of application affected biomass yield and nutritive values of forages.
