A study of some of the factors that influence the yield and the composition of growing pasture grass . ases steadily throughout the season. Startingwith and ending with percent. 4. The ether extract is increased the first two months from percent and decreased the remainder of the season from to per-cent. 5. The ash cortent of the grass is increased in May, July, August to percent and decreased in June, September and October from percent. 6. The carbohydrates are decreased from to percent. Thegreatest decrease occurs the last two months. 7. The nutritive ratio is narrowed from to points. This ismost apparent in August and September. .Influence of Frequency of Cutting 1. The yield of grass is decreased by frequent cutting. Comparedwith the biweekly cut plot, the annual loss on the weekly cut plot is Compared with the plot cut twice yearly, the loss is pounds. 2. Cutting grass biweekly instead of weekly decreases dry matter inmid-season, for the untreated plot. In case of the disced plot, in the. -110- majority of cuttings,the dry matter is decreased. The dry matter in thedisced manured plot is increased, except in the latter part of May and Au-gust. The increase varies from to percent, while the decreaserange- from to percent. The dry matter for the grass cut twiceyearly, is nearly .12 percent more than that cut weekly. 3. The protein content is largest in the grass cut weekly. Cuttingbiweekly decreases the percent protein percent (yearly average) andcutting twice a year, percent. The difference is more evident in thegrass from the treated plots. The disced plot lost percent, while thedisced, manured plrts lost percent. 4. Ether extract decreases the latter part of the season for the un-treated plot, in the biweekly cut grass. It increases for the discedplot and the disced, manured plot. An increase in one case of percentis noted.
