Productivity of Coastcross-1 pastures mixed with cool-season legumes/ Produtividade de pastagens de Coastcross-1 em consorcio com diferentes leguminosas de ciclo hibernal

The objective of this research was to evaluate three grazing systems with Coastcross-1 (CC) + 100kg N [ha.sup.-1] [year.sup.-1] + common vetch; CC + 100kg N [ha.sup.-1] [year.sup.-1] + arrowleaf clover; and CC + 200kg N [ha.sup.-1] [year.sup.-1]. Thirteen grazing cycles were performed during the experimental period (345 days). Lactating Holstein cows were used in the evaluation. The forage mass, botanical composition, leaf/stem ratio; daily accumulation rate, production and forage intake; grazing efficiency and stocking rate were evaluated. The average of forage production and stocking rate were 21.0, 20.3, 24.3t [ha.sup.-1] and 7.0, 6.5, 7.7 animal units [ha.sup.-1] [day.sup.-1] for the respective forage systems. Better results were found on Coastcross-1 mixed with common vetch and Coastcross-1 alone.
