The influence of agronomic practices on forage production and chemical composition of grass-legume pasture mixture was studied at the Utah State University Dairy Farm, North Logan, Utah, during spring and summer, 1970. The soil is a well-drained Millville silt loam that has about a 1 percent slope . It is high in potash, phosphorus, and lime, having a pH of 7.9.
Analysis of the clipping management showed that the early spring clipping decreased the yield of forage. The losses in total yield due to spring clipping were approximately four to five times the yields received in early spring clipping. The grasses were affected more than the legumes.
The yields of dry forage increased with the increase in fertilizer rates from 0 through 300 pounds of nitrogen per acre. There was no advantage to splitting the nitrogen fertilizer of 300 pounds per acre into three applications. Most of the effects of spring clipp1ng and nitrogen fertilization were re fleeted in the first summer harvest.
The plots fertilized with nitrogen produced a higher yield and nitrate content than the check plots. Legumes were higher in nitrate on the unfertilized plots than the grasses, but lower on the fertilized plots.
