Description
The effects of three frequencies (15; 30 and 45 days) of defoliation were assessed on a five-year-old temperate pasture composed of tall fescue (Festuca arundinacea Schreb.), white clover (Trifolium repens L.) and birdsfoot trefoil (Lotus corniculatus). Total annual DM yield showed a significant lower production for the most frequent defoliation management, 30 and 45 days frequency treatments averaging 32% more forage production with no statistical difference between them. Spring was the only season in which the more lenient defoliation significantly outyielded the 15- day interval treatment, which made up for the annual difference recorded. Through the rest of the seasons evaluated, the difference between extreme frequencies was nonsignificant, highlighting the efficiency under which each management produced harvestable material.
