SCHEFFER-BASSO, Simone Meredith and GALLO, Milena Maria. Morphophysiological and bromatological aspects of Paspalum plicatulum. R. Bras. Zootec. [online]. 2008, vol.37, n.10, pp. 1758-1762. ISSN 1806-9290. http://dx.doi.org/10.1590/S1516-35982008001000007.
This work aimed to evaluate the forage value of a brown-seed grass (Paspalum plicatulum) population, considering bromatological aspects and dry matter accumulation. Plants were obtained from tussocks and they were established in a weed-free area 80 cm apart from each other. The experimental design was completely randomized and treatments consisted of plant age after establishment characterized by days (D) and degree-days (DD) accumulated above 0ºC. Harvests were performed at ground level in late-spring (27 D, 587 DD), mid-summer (68 D, 1534 DD), mid-fall (149 D, 3311 DD), and mid-winter (226 D, 4527 DD). Brown-seed grass showed 11-22% of crude protein, 39-46% of acid detergent fiber and 55-66% of neutral detergent fiber, good tolerance to summer drought, and produced green dry matter during spring, summer and fall. Growth stopped when the temperatures dropped below 15ºC. Morphologically the population showed a high tillering potential (105/plant), compact tussocks (circumference = 53 cm), basal sprouting, and erect growth.
