A study of some of the factors that influence the yield and the composition of growing pasture grass . uly and August to percent in In-crease develops,however,in the late October grass ranks second inash content, about one-half to one percent above the early grass. Considered from both the fresh basis and the water free basis, afterJune, the grass suffers a decline in ash content until the last month of thepasture season, when a rise of about percent develops. Influence of Tillage The data for the influence of tillage upon the ash content of pasturegrass is found in the first column of Tables 37 and 38 and the first curvein Charts XXVIII. From the results upon this point it appearsthat during the summer months of the pasture season the effect of tillage isto lower the ash content of the grass. Charts XXVIII. show thispoint quite clearly. The effect upon the early and late grass, however,is to increase the ash content. This depressing effect of tillage upon theashcontent amount to from to percent, while the benefits derived. -69- amount to increases varying from to percent .on the fresh basis. The Influence of Manure The data for the effect of manure upon the percent ash in pasture grassis found, as in the other cases, along with the tillage data in Tables 37,and 38, and Charts XXVII. and XXVIII. This particular data is found in thesecond column of the tables and the second curve of the charts. From a study of the charts, it is evident that manuring has a tendencyto increase the percent ash in grass. With the latter part of the seasonas an exception, this statement is prompted by the trend of the second curvein Chart XXVII. The corresponding curve of the water free basis data isstrong evidence supporting the statement. It appears, therefore, thatthroughout the season a uniform increase (water free basis) of about in the ash content is produced by manure. The October grass is thesing
