Effect of defoliation frequency and severity during winter on herbage regrowth and water‐soluble carbohydrate content of perennial ryegrass (Lolium perenne L.) dominant swards

摘要

Perennial ryegrass is one of the world's primary grazed grasses in temperate regions.To retain the low costs of production vital to the prosperity of industries that rely on ryegrass,it is necessary to maximise herbage growth.Grazing management decisions can have a positive or negative impact on regrowth.Although results have been inconsistent,two such decisions include the frequency and severity with which swards are defoliated.
