Early Harvest

Timothy, tall fescue, reed canarygrass and Kentucky bluegrass plots were harvested at weekly intervals from the vegetative stage through to seed maturity for 3 yr in order to evaluate the effect of harvest and species on nutrient production. The forage of the early harvest regimes was cut after 5 wk of regrowth and all plots were harvested in the fall. In vitro dry matter digestibility (IVDMD) values ranged from above 80% down to 45%, with an average rate of decrease during June of 0.74, 0.84, 0.85 and 0.45% per day in timothy, tall fescue, reed canarygrass and Kentucky bluegrass, respectively. Similarly, crude protein (CP) in first-cut forage ranged from 28% to 6% and had respective decreases of 0.47, 0.40, 0.39 and 0.28%/day. Regrowth forage in the midsummer and fall harvests averaged from 63 to 59% IVDMD and from 16 to 20% CP, respectively. With the exception of reed canarygrass, delaying the initial cut resulted in continued increases in total annual dry matter (DM) yield, significant increases in total IVDMD yield until flowering, and decreases in total CP yield from stem elongation onwards. Reed canarygrass reached its optimum CP yield at early heading and had significant increases in IVDMD yield until the flowering stage. Harvesting all forages at the stem elongation stage substantially reduced the yield of DM, IVDMD and CP. Although most of the DM was obtained in the initial harvest, almost half of the total CP was obtained in the final harvest.Key words: Timothy, tall fescue, reed canarygrass, Kentucky bluegrass, growth cycle, forage quality

Forage Yields

Four broadleaf herbicides and combinations were compared for two years with mefluidide, a growth regulator, for effects on ‘Ky 31’ and ‘Fawn’ tall fescue. Seedhead densities averaged 33% of the check with 8.4 g ai/ha of metsulfuron, 17% with 70 g ai/ha of imazethapyr, and 9% with 280 g ai/ha of mefluidide, while forage yields were reduced to about 40% of the check. Forage crude protein (CP) concentrations were increased by mefluidide, imazethapyr, and 8.4 g/ha of metsulfuron. Neutral-detergent fiber (NDF) of Ky 31 but not Fawn forage was reduced by mefluidide, imazethapyr, and metsulfuron at 6.3 and 8.4 g/ha, but Fawn NDF was increased by dicamba plus 2,4-D. In vitro dry matter digestibility was increased by metsulfuron at 6.3 and 8.4 g/ha, mefluidide, and imazethapyr in one of two years. Adding 2,4-D to metsulfuron reduced some effects of metsulfuron. Total CP/ha was no more adversely affected by imazethapyr and metsulfuron than mefluidide. Imazethapyr and metsulfuron can thus be used to control weeds without reducing fescue forage value.

Rate Of Decline

The in vitro dry matter digestibility (IVD) of timothy, orchard, brome, reed canary, tall fescue and mountain rye grasses decreased at the rate of approximately 0.5 per cent per day throughout the growing season. The most rapid decline in IVD began with head emergence. The earliest maturing grasses tended to be higher in IVD than the other grasses at the flowering stage. The decline in IVD as the season progressed was observed in all portions of the plant, the rate of decline for the heads and stems being greater than for the leaves. The upper segments of the stems tended to have a lower IVD than the basal segments.

Percent Composition

Silicon (Si) is distributed throughout plant tissues, but its role in forages has not been clarified. Although Si has been suggested as an antiquality factor which limits the digestibility of structural carbohydrates, other research indicates that its presence in plants does not affect digestibility. We employed x-ray microanalysis to evaluate Si as an antiquality factor at specific sites of two cultivars of bermuda grass (Cynodon dactvlon (L.) Pers.). “Coastal” and “Tifton-78” were chosen for this study because previous work in our lab has shown that, although these two grasses are similar ultrastructurally, they differ in in vitro dry matter digestibility and in percent composition of Si.Two millimeter leaf sections of Tifton-7 8 (Tift-7 8) and Coastal (CBG) were incubated for 72 hr in 2.5% (w/v) cellulase in 0.05 M sodium acetate buffer, pH 5.0. For controls, sections were incubated in the sodium acetate buffer or were not treated.
