Effect of harvest time and cutting height on the grass growth, yield and botanical composition in pasture mixtures



Effect of harvest time and cutting height on the grass growth, yield and botanical composition in pasture mixtures



Research Reports of the Rural Development Administration 34(1 LIVEST ): 75-80



A field experiment was carried out to determine the effects of harvest time (grazing, soiling and hay stage) and cutting height (3, 6 and 9cm) during the growing season on the grass growth, dry matter (DM) yield, DM distribution and botanical composition in pasture mixtures dominated by orchardgrass, 1987 and 1988. Average height of grasses was 35cm in grazing, 51cm in soiling and 77cm in hay stage, and the height was increased with higher cutting height. Total DM yield was not significantly influenced by harvest time and cutting height. However, the regrowth yield and good seasonal distribution of DM were obtained in high stubble height, regardless of harvest time. Also, cutting height of 6 to 9cm maintained higher percentage of pasture plants and lower weed development in all harvest time. 6cm of cutting height in spring and 9cm of stubble height in summer and autumn season are recommended regardless of harvest time of grazing, soiling and hay stage.
