Abstract/Contents:"The effect of nitrogen fertilization (0, 50 and 100 kg/ha) and regrowth age 1 to 12 weeks on the chemical composition of Coast Cross cv. No. 1 bermuda grass was studied during the dry season using sprinkler irrigation. Crude protein tended to decrease with age, increasing with the N levels up to 20% with 100 kg N/ha. Total soluble carbohydrates (TSC) were influenced by age (P < 0.001); the same did not hold true for N. The adjustment of regression equations for lignin and cellulose showed increasing values with respect to age. In vitro DM digestibility (IVDMD) showed significant differences (P < 0.001) only when 100 kg N were applied (50.46%). The two other levels did not differ between them, being 43.45 and 46.11% for 0 and 50, respectively. The highest value obtained was 62.07% in the fourth week with 100 kg N. From the 8th week a sharp trend to decrease was found for all the treatments. Suggested is the use of 100 kg N/ha every twelve weeks an cuts between the fifth and sixth weeks in order to obtain good quality pastures."
