blooiniii«r. tlioiia-h the potash plats still shoAvod the thickest stand. 

 A table of results at hnr\'est shows little dilf'ereiice in the actual 

 yields, thus MppMi'cntly iiidicatiiii:- that "this soil did not need fer- 

 tilizers for wheat. Conchisions, however, should not be made from 

 one year's triah as the season may have a marked etfect. These 

 experiments will be conlimied from year to year on the same plats." 



A series of plats used in held experiments with fertilizers on wheat 

 for two years pivvious was again seeded in the autumn of 188S with 

 wheat of tlie Kxtra Early \'ariety, to observe the effect of fertilizers 

 renuiinino- in the soil. " While the effect of the fertilizers is not well 

 mai'ked. it is still evident that there is a slight advantage in favor of 

 the fei-tilize(! ])lats. and the yields of the last season show perceptibly 

 the effects of the fertilizers applied in former years.''

Bl'LLETIN No. 22. DECEMBER, 1889. 



Potato EXPEraMEXTS ix 1880 (pp. :)-:2;)'). — A report of the contin- 

 uation of experiments on the Station farm. '" The soil on which all 

 of our experiments are made is what is called a ' Blue-grass ' soil. It 

 is (lerive(! fi'oni tlu' limestones of the Trenton group of the Lower 

 Silurian. These limestones in general are rich in j^hosphoric acid. 

 The subsoil of the farm is a light-colored clay, not easily permeable 

 by water, and therefore the ground is generally wet and cold in the 

 early spring. The soil is well worn by contiiuied cultivation."" 



7'c.sts of r'/r/cfics (pp. -1-10). — Tal)ulate(l notes of growth and yield 

 for 57 varieties, and of the dry substance, wat^^r, average weight of 

 one ])otato. and specific gravity for each of 51 varieties. 



McfJindx of pl.'dif'nig (pp. 10-14). — (1) The trench system was 

 com])ai-e(l with the usual method of planting for Early Rose and Bur- 

 b;uik potatoes. ( li ) The yields from planting 14 and 20 inches apart 

 in the row are compared. 



Preparation of seed (pp. 14-16). — The yields are compared from 

 planting northern grown seed of Early Rose on five small plats, as 

 follows: Large potatoes, two eA'es, cut in two, and whole: small, 

 w'hole; medium, two eyes. The amounts planted |»m- acre varied 

 from () bushels of medium, cut to two eyes, to 48 bushels of large 

 whole potatoes. 



Field exjyeriments with fertUizcr,s (pp. 1(5-23). — Xitrate of soda, 

 acid phosphate, and sulphate of potash, singly and in combination, 

 and land plaster were comi)ai-ed with no maniii-e on ten plats. The 

 tabular records include data for the yield, i)rofit or loss, and effect of 

 the fertilizers on the quality of the product. Photo-engravings of 

 the piles of i)otatoes harvested on each of six ])lats are given.
