“…The presence of legume (grass-legume system) increased forage allowance (p < 0.05) in all seasons compared to those of the pure grass systems even though the same amount of N fertilizer was used in both cases ( Table 2). The mixed pasture and the T + 200 pure grass systems were similar to each other in spring and autumn because the nutritive value of the pasture was increased at high N fertilizer levels (Barbero et al, 2010;Olivo et al, 2017). For this reason, these systems also had similar annual herbage yields among these systems.…”

“…A good alternative to nitrogen fertilizer use is a mixed grass-legume pasture because legumes fix atmospheric nitrogen and promote nutrient recycling in the soil (Abdul-Baki et al, 2002;Nascimento, 2006). Legumes can, therefore, increase herbage yield and nutritive value, improve seasonal forage distribution (Ames et al, 2014), and decrease nitrogen fertilizer use, thereby reducing its adverse environmental impact (Olivo et al, 2017). Pinto peanut (Arachis pintoi Krap.…”

Mixed pasture grass-legume systems balance forage supply and minimize environmental impacts by reducing the need for nitrogen fertilization. Pinto peanut (Arachis pintoi Krap. and Greg. “Amarillo”) has several traits that are suitable for mixed pastures but have not yet been adequately explored. The aim of this study was to evaluate a mixture of Tifton 85 bermudagrass (Cynodon dactylon) and pinto peanut and evaluate forage yield, crude protein, and stocking density. A two-year study of three grazing systems was used with the following treatment combinations: (a) Tifton 85 (T) + 100 kg N ha-1 yr-1 + pinto peanut (T + PP+100); (b) T + 100 kg N ha-1 yr-1 (T + 100; control, pure grass); and (c) T + 200 kg N ha-1 yr-1 (T + 200; positive control, pure grass). In this study, forage yield, pasture characteristics and responses of lactating cows were evaluated. The experimental design was completely randomized with three treatments (grazing systems), three replicates (paddocks), and repeated measures (grazing cycles within seasons). Forage accumulation, crude protein concentration, and stocking rate were 15.1; 11.3 and 14.1 t DM ha-1 yr-1; 17%, 16%, and 17%; and 5.3; 4.9 and 6.1 AU ha-1 day-1, respectively. The grass-legume system yielded the best results.

“…In these conditions, the forage yield is concentrated in the summer (Seibt et al 2018), with dependence of commercial nitrogen and involves high production costs and environmental issues. Elephant grass under organic production can more sustainable, but few studies have investigated this production system (Olivo et al 2017). The aim of this research was to evaluate elephant grass-based pasture under organic and conventional production systems on the botanical and morphological compositions, herbage yield, nutritive value, grazing efficiency, forage intake, extraction/ export nutrient (N) and forage yield, and stocking rate.…”

Elephant grass (EG) (Pennisetum purpureum Schum.) have great importance in tropical and subtropical climates, especially on dairy farms. Normally, EG is established alone under high fertilization levels. EG in organic production system can improve low production costs and environmental issues, are still little known. The aim of this research was to evaluate the performance of herbage yield, nutritive value, extraction/ export nutrient and forage yield and animal responses. Three production systems of EG were analyzed: (i) EG mixed spontaneous-growing species (SGE) in warm-season and ryegrass (R) in cool-season under organic production; (ii) EG mixed SGE + R under conventional system (positive control); and (iii) EG based under conventional production (control). Holstein cows were used in a rotational stocking. Forage samples were collected to evaluate the pasture and animal responses. Seven grazing cycles were performed during the experimental period (312 days). Herbage yield, forage intake, and stocking rate were 12548; 10270; 19168 kg ha -1 and 2.5; 2.6; 2.7% and 3.3; 2.1; 4.5 AU ha -1 day -1 , respectively. Crude protein of EG was 17.9; 15.4; 16.4%, respectively. Mixed pastures, in conventional and organic production, had a better forage distribution throughout the seasons. Highest forage yield and extraction/ export nutrient was reported in pure EG within the conventional system.

The effects of growing pinto peanut mixed with elephant grass-based pastures are still little known. The aim of the current research was to evaluate the performance of herbage yield, nutritive value of forage and animal responses to levels of pinto peanut forage mass mixed with elephant grass in low-input systems. Three grazing systems were evaluated: (i) elephant grass-based (control); (ii) pinto peanut, low-density forage yield (63 g/kg of dry matter – DM) + elephant grass; and (iii) pinto peanut, high-density dry matter forage yield (206 g/kg DM) + elephant grass. The experimental design was completely randomized with the three treatments (grazing systems) and three replicates (paddocks) in split-plot grazing cycles. Forage samples were collected to evaluate the pasture and animal responses. Leaf blades of elephant grass and the other companion grasses of pinto peanut were collected to analyse the crude protein, in vitro digestible organic matter and total digestible nutrients. The pinto peanut, high-density dry matter forage yield + elephant grass treatment was found to give the best results in terms of herbage yield, forage intake and stocking rate, as well as having higher crude protein contents for both elephant grass and the other grasses, followed by pinto peanut with low-density forage yield + elephant grass and finally elephant grass alone. Better results were found with the grass–legume system for pasture and animal responses.
