The influence of density and nitrogen in seed production stands of S48 timothy and S215 meadow fescue


The influence of density and nitrogen in seed production stands of S48 timothy and S215 meadow fescue



J Agr Sci 63(1): 35-42



-Seed production stands of S 48 timothy and S 215 meadow fescue were obtained with varying plant densities by utilizing two drill widths, removing sections of drill, or oversowing drilled material. All density treatments were operative at two levels of N, 61 or 122 lb N/acre/per year. Annual tiller counts were made in preselected quadrats, and performances of tiller populations were assessed from these quadrats. Timothy seed yields were generally reduced by removing sections from the drills, compared with 2 ft continuous drills at the high level of N, but one removal treatment increased yield. Meadow fescue yields were not increased by any gapping treatment, and in many instances were considerably reduced. Oversown plots, which gave the lowest yields in timothy, gave better yields than several gapping treatments in meadow fescue. The overall effect of N on seed yields was generally positive but not significant. Tiller numbers increased in most treatments over the course of the experiments. Higher tiller numbers per quadrat were obtained with lower plant densities. Nitrogen generally had small but positive effects on tiller numbers. Percentage fertility of tillers was generally higher with lower plant densities and lower tiller numbers per quadrat, other factors being equal. In meadow fescue, percentage fertilities were higher than in timothy, and were not so much affected by plant density. In timothy there were no significant effects of N on percentage fertility, but, as tiller numbers tended to increase with high N as the stand aged, so fertility tended to decline. Nitrogen had a positive effect on the fertility of meadow fescue tillers in the 2nd year. The weight of seed per ear was very variable, but it appeared to be reduced by increased plant density, and by increased tiller density per quadrat with age. It was slightly increased by N in timothy, and was increased by 20% by N in meadow fescue in 1958.
