Synopsis A new technique to increase crude protein levels of pangolagrass was studied. Average crude protein contents of mature pangolagrass were increased from 4.5 to 9.2 and to 12.3% when 45 and 90 pounds of N per acre were applied, respectively, about 4 weeks prior to clipping in January. The amount of increase depended upon the rate of N applied and the amount of grass present when fertilized. The N application had little effect on January grass yields. Different late summer and fall dates and rates of fertilizer, however, markedly affected winter yields but had only slight influence on winter crude protein levels.
