Conteúdo: |
A grass-legume pasture composed primarily of coastcross-1 bermudagrass (Cynodon dactylon (L.), Pers.) and greenleaf desmodium (Desmodium intortum (Mill) Urb.) was evaluated in a grazing trial during 182 days in the growing season of 1975 at the beef research unit, University of Florida, Gainesville. The pasture was established in 1974 on a soil of the sparr series associated with the blanton series. The main objectives of the study were (a) to determine the effect of grazing period (X1), rest period (X2), and grazing pressure (X3) upon the pasture mixture, (b) to evaluate a response surface design for the statistical analysis of the experiment, and (c) to evaluate the forage residual dry matter as an estimator of grazing presure. Grazing periods studied were 1,2,5,7,10.5, and 14 days; rest periods were 0,14,28,42 and 56 days; and projected grazing pressures were .5, 1.0, 1.5, 2.0, and 2.5 metric tons/ha of dry matter (DM) leaf after grazing. Modifid mon-rotatable central composite design made up of eight factorial, six axial, one central, and five extra treatments was used to study the response surface of the individual response variables. |
