Abstract

Common guinea grass and new accessions of Panicum and Cenchrus grasses were evaluated in a cutting experiment in the semi-arid Lajas Valley over three periods: 126 days of cool weather and short days; 378 days; and nearly 2 years (672 days). The grasses were fertilized with 3,360 kg.ha-1 of a 15-15-10 fertilizer, divided in eight equal applications. The grasses were irrigated. The grasses were harvested every 42 days. In the 126-day period of short cool days, buffel 13084 and guinea 12917 were the highest dry forage yielders, with 11,371 and 11,061 kg.ha-1, respectively. In the 378-day period, guinea #13093, #12917 and #13092 produced statistically similar dry forage yields, which were higher than those of the other grasses. Among the Panicum grasses, guinea 13093 was the highest dry forage yielder (45,574 kg. X-1); among the Cenchrus grasses, buffel 13084 was the highest yielder (35,247 kg. X-1). In the 672-day period, guinea #13093, #13092, and #12917 outyielded var. common and all buffel grasses.
