Abstract

The regrowth of cuttings imposed on a elephant grass stand during the end of the rainy season (2-28, 3-21, 4-11 and 5-2) were evaluated at 28-day intervals during the dry-season (6-18, 7-16, 8-14 and 9-12), during two years at the €œEstação Experimental de Nova Odessa, E. S. Paulo€. During the dry-season the 2-28, 3-21, 4-11 and 5-2 regrowth (average of the 4 cuttings during the dry-season) yielded, respectively: 2,303, 1,005, 366 and 358 ± 61 kg of DM/ha (2-28 > 3-21 > 4-11 = 5-2, P < 0.05); presented. respectively: 5.9; 8.3; 11.0 and 12.2 ± 0.9% CP (2-28 3-21 < 5-2, 2-28 < 4-11, P < 0.05) and 34.0; 31.8; 29.5 and 28.3 ± 0.3% CF (2-28 > 3-21 > 4-11 > 5-2, P < 0.05). The height of the elephant grass stand was measured at each cutting and related with the dry matter production. It was found out that the dry matter production expressed in kg/ha (Y) is related to the height of the elephant grass stand expressed in centimeters by the following equation: log Y = 1.69865 log X €” 0.05435, s = ± 0.07197 and r2 = 0.9673.
