THE EESEEDING OF DEPLETED GRAZING LANDS. 7 



RESULTS. 



COMPARATIVE SUCCESS OF THE VARIOUS SPECIES. 



Of the 449 experiments observed during the calendar year 1911, 

 168, or 37.42 per cent, were failures ; 112, or 24.95 per cent, were par- 

 tial successes ; 71, or 15.81 per cent, were fully successful ; 64, or 14.25 

 per cent, were undeterminable at the end of the season; and in the 

 case of 34 experiments, or 7.57 per cent of the total, the results were 

 not definitely declared. Grasses were used in most of these experi- 

 ments. The following table is presented to show the results in the 

 case of single or pure sowings.

Table 1 shows that by far the best results were secured with timo- 

 thy, 64.37 per cent having been successful or partially successful. 

 It will be observed that this species was employed in 87 projects, from 

 the Canadian to the Mexican boundaries. Despite the fact that the 

 results of a part of these experiments were not declared, over three- 

 fifths gave good returns. 



Next in the category of successful results are : Smooth brome grass 

 with 58.14 per cent, perennial rye grass Avith 50 per cent, Italian 

 rye grass with 37.5 per cent, Kentucky blue grass with 31.82 per cent, 

 and redtop with 33.33 per cent. It is interesting to note that the 

 more drought -resistant species, notably smooth brome grass, perenniaj 

 rye grass, etc., rank among the first in the successful seeding. The 

 figures given in Table 1 are comparable in each case to the results 

 obtained where these species were seeded in mixtures. As far as the 

 returns show, all trials of meadow oat grass and hard fescue gave 

 negative results. 



Very few of the nongrasses yielded satisfactory returns. Those 

 worthy of consideration are white and alsike clovers and alfilaria. 

 Of the trials with white and alsike clover, 41.67 and 14.82 per cent,
