Sward structure effects on light interception in rotationally-grazed orchardgrass (Dactylis glomerata L.)

摘要

Grazing managers need to know the relationship of sward height and mass to photosynthetic capacity. The aim of this study was to measure the interception of photosynthetically active radiation (PAR) and relate it to sward structure throughout the grazing season on rotationally-grazcd orchardgrass/cocksfoot (Dactylis glomerata L.) pastures.
