. Bulletin of the Department of Agriculture. Agriculture; Agriculture. 28 BULLETIN 219. U. S. DEPARTMENT OP 30 * to X. 5; 30 \ O 40 1 WILL tSTC At ⢠SC :ott SBLL y / Figure 6, prepared from Table VIII, shows graphically the average relative profit or loss attending the use of each of the five methods at each of the stations. Table XVIII, illustrated in part in figure 4, shows that during the years covered by this work creditable average yields of grain have been obtained by all methods at Huntley, Williston, Dickinson, Scottsbluff, North Platte, and Akron, and by one method at Belle Fourche and Dalhart. No grain has been produced either at the Judith Basin Field -*â Station or at Garden City. Little difference is shown in the average yields of grain by the different cultural methods in use at Williston, Edgeley, Hays, and Amarillo. At Dickinson, Belle Fourche, and Dalhart the only method of preparation giving yields departing far from the others has been that of summer tillage. At Dickinson summer tillage has been responsible for a decrease in yields and at Belle Fourche and Dalhart for an increase. Between the yields following fall and spring plowing little general difference is to be noted, except that at Huntley fall plowing has been better than spring plowing, and at Scottsbluff fall plowing after corn has been better and fall plowing after small grains poorer than spring plowing after either. At some stations more difference is to be noted as a result of crop sequence than as a result of difference in time of plowing. At Huntley corn has been better after small grain than after corn. At both North Platte and Akron corn after corn by both fall and spring plowing has been markedly better than corn after small grain. c VCKj AtSC A/ AtC 7RTH PLA TTE o Fig. 4.
