Abstract

Thirteen treatments corresponding to the elephant grass clones CUBA CT-169, Cuba CT-115 and king grass cut 2, 4 and 5 times per year, were compared to the sugar cane varieties Jaronu 60-5 and V-C21 cut once ortwice yearly A random block design with 5 replications was used during 4.5 years of evaluation. Cumulative dry matter yield of the elephantgrass clones decreased (P<0.001) on increasing the cutting frequency. The cumulative maximum values per cutting frequency were: 185.1; 95.8and 72.4 MR DM.ha(-1) for the lung grass (2 cuttings) and Cuba CT-169(4 and 5 cuttings), respectively. The 21 sugar cant clone (114 Mg Dm.ha(-1) surpassed (P<0.001) the Jaronu 60-5 (87.5 Mg DM.ha(-1)) cut once yearly. Yield of the elephant grass clones was higher (P<0.001) to that of sugar cane when cut twice parry. While sugar canes (100%) whichare cut in the dry season, had the highest yield, the second place inthis period was for elephant grass (63-70%) cut 4 times per year The lowest height was obtained with the Cuba CT-115 in all cutting frequencies. With 2 cuttings per year it was of 154.1; 223.9 and 221.2 cm forCuba CT-115, king grass and Cuba CT-169, respectively. The sugar canes Jaronu 60-5 and done 21 accumulated 209 and 283 cm, respectively with one cutting, also they showed the lowest leaf percentages (12-14%) and the greatest cutting resistence. The high influence of the cutting frequency on biomass production of elephant grass, as well as the alternatives it offers to livestock production the characteristics of the clones and their exploitation are discussed.
