OQUEND, G et al. Seed production of Guinea grass (Panicum maximum Jacq.) in an intensive cattle fattening system. Pastos y Forrajes [online]. 2008, vol.31, n.3, pp.1-1. ISSN 0864-0394.

On a sialitic Brown soil of the calcic Cambisol subtype, located at the «Calixto García» Livestock Production Enterprise, in the Holguín province, the production of Guinea grass (Panicum maximum Jacq.) was studied in an intensive cattle fattening system, with irrigation. The treatments were five varieties of Guinea grass: A) Common; B) Likoni; C) Mombasa; D) Tanzania; and E) Tobiatá. The following methods were considered, in turn, sub-treatments: 1) Seeding with gamic seed; 2) Planting with tillers; and 3) Transplanting. The stocking rate remained adjusted at 2 animals/ha. In seed production there were favorable interactions between the planting methods and the varieties: gamic seed-Guinea grass Likoni; tiller-Guinea grass Mombasa, Tanzania and Tobiatá; transplantation-Common guinea grass. In the whole exploitation an additional contribution higher than $1 000/ha was obtained for seed production, without affecting animal production, in which gains higher than 800 g/animal/day and average productions of 46 212 t of meat per fattening cycle were obtained. The seed production of Guinea grass in intensive cattle fattening systems is considered feasible.
