A study of some of the factors that influence the yield and the composition of growing pasture grass . uction, succeeded by further decreasefor the last week, - the second week in October. A good growth in Kay and early June diminishing to August, with areturn to May and June yields in the fall is characteristic of the growthcf Blue Grass. The results here presented vary from the expected,in thatthe month of June is the poorest of the pasture season. The date inTable 2, which is a condensation of Table 1, brings out this point. Afurther inspection of the data in this table reveals monthly intermittentvariations in yield, starting with May as the high point and alternatinghigh and low yields per month throughout the season. This observationis presented graphically in Chart 1. Influence of Tillage upon the Yield The data upon this point is presented in Table 3. The results areexpressed in weight increase and in increase in percent of undisced plotyields. From this table, it will be observed that the increase in yielddue to tillage is small, outside the initial cutting, at the forepart of. -li- the pasture season. A pronounced effect is first produced,beginning withthe month of July. From this time on an increase of from 25 to 62 per-cent of the undisced plot yields is observed. Chart II. presents thedata of Table 3 in a more comprehensible form. It will be noted thatwhile the comparative increase; that is, the percent increase in yield islarge ,the actual weight increase is snail. The effect upon the total monthly yields is tabulated in Table 4 andplotted in Chart III. This chart presents the results in a still morecomprehensible form than Chart II. From these data it is evident thattillage has a beneficial effect upon the growth of pasture grass. Thiseffect is most pronounced during the latter part cf the pasture season,particularly during the months of July and September. The total annual increase expressed in weight is poundswhile in terms of percent
