Conclusions 



Yield: Broniegrass fertilized with high rates of nitrogen properly bal- 

 anced with phosphorue and potassium produced the highest dry matter 

 yield in the third stage of maturity. Nitrogen applied after the first cut- 

 ting greatly increased the yield of the second cutting. 



Fertilization: The best results were obtained where nitrogen was ap- 

 plied at the rate of seventy-five to one-hundred pounds per acre before 

 the first cutting. After an early harvest ( middle of June I . fifty to seventy- 

 five pounds of nitrogen per acre should be applied to encourage rapid 

 growth of the second crop. Whei*e the nitrogen carrier is acid and ap- 

 plied at a high rate, additional lime should l)e used. For, where a total 

 of eight-hundred pounds of urea nitrogen was applied over a two year 

 period the pH of the plots dropped from 6.2 to 5.5. 



Persistency : Without sufficient phosphorus and potassium, high rates 

 of nitrogen resulted in severe lodging and a reduction in persistency. At 

 the low rates of nitrogen, the persistency of the stand was lowered by 

 the invasion of red clover. Figure 8. 



Protein: The protein content of broniegrass generally increased as the 

 rate of nitrogen increased.
