Description
This experiment was conducted with the aim of studying whether the frequency and intensity of defoliation of the temperate grass fromental (Arrhenatherum elatius (L.) Presl.) affected its total dry matter (DM)/ha yield as well as the seasonal distribution of forage. Plots were seeded in 1988 and data collected from 1989 to 1991. Two frequencies and two intensities of defoliation were combined in a two factor randomized complete block design with six replications. Treatment plots were cut each year from early autumn to late spring. ANVA, Tukey and Dunnett tests were applied to find out differences between treatments and between treatments and control. Statistical significance was assumed at p<0.05. For the environmental conditions of this experiment cutting intervals were consistently responsible for differences in total DM yield: BI and BII were superior. The more productive treatment (BI) differed from those of better forage seasonal distribution (AI and AII).
