E.  aEffect of nitrogen rate and clipping frequency upon lignin content and digestibility of Coastal Bermuda grass.  c1958  aThis study was conducted to ascertain the effect of nitrogen fertilizer and clipping frequency upon the lignin content and digestibility of Coastal Bermuda grass when fed to lambs. When the grass was fertilizer with 100 pounds or less of nitrogen per acre, clipping frequency did not affect lignin content; at higher nitrogen rates, lignin increased with age of the grass. Grass ferilized with 600 pounds of nitrogen per acre increased from 9.45 to 12.05% lignin with an age increase from 2 to 8 weeks. Total digestible nutrient values of 69.64, 67.81, 67.23, 67.24, and 59.07% were obtained from 1- to 2-, 3-, 4-, 6-, and 8-week-old grass, respectively, fed to lambs. Not more than 6 weeks should elapse between cutting if top-quality Coastal Bermuda hay is desired.  adigestibility  aCarneiro  aDigestibilidade  aPastagem  aCoastal Bermuda grass  aEfeito  aEffect  aLamb  aNitrogen rate  aPasture  aTaxa de nitrogenio1 aBURTON, G.
