EXPERIMENT STATION RECORD. 



turnips indicated the need of fertilizers particularly rich in available 

 phosphoric acid and potash. Dissolved boneblack and muriate of pot- 

 ash were found to be useful forms of these fertilizers, but the author 

 believes that other available phosphoric fertilizers would be as good as 

 dissolved boneblack. A combination of these fertilizers seemed essen- 

 tial to a large increase of crop. The test with soy beans showed that 

 potash had the greatest effect upon the increase and the quality of the 

 crop. Muriate of potash was used, but it is stated that the sulphate 

 has been found superior to it for beans. In the soil tests with corn 

 potash was found to be the controlling element. 



Manuring the corn crop (pp. 10--51). — Applications of cords of barn- 

 yard manure per acre and 4 cords of manure with 100 lbs. of muriate 

 of potash per acre were made annually during years of corn culture 

 on the same land. Manure alone gave the best results. Under the same 

 conditions the mixed fertilizer corresponding in composition with the 

 "special" corn fertilizers found upon the market in 1891 was compared 

 with a fertilizer rich in potash but furnishing less nitrogen and phos- 

 phoric acid. The " special" fertilizer gave rather more grain and less 

 stover, but the author considers the financial advantage to lie with the 

 fertilizer richer in potash. In connection with these experiments hill 

 and drill culture were tested. Drill culture produced the largest yield. 



For green manuring in continuous corn culture white mustard sown 

 in standing corn when last cultivated was found recommendable. 



Variety tents (pp. 1G-34). — Among 00 varieties of potatoes Carman 

 No. 1, Fillbasket, New Satisfaction, Early Maine, and Dutton Seedling, 

 in the order named, produced the largest yields. White Flint, Sanford, 

 Compton, Early Giant, Long White, and Longfellow were the best 

 among 21 varieties of flint corn. Yellow Kose, Mastodon, Eeed Yellow 

 Dent, New Golden Triumph, Learning, and Sibley Pride of the North 

 were the best among 40 varieties of dent corn. 



Mammoth clover gave better yields than common red clover, and is 

 recommended for sowing with timothy. Alsike and crimson clover 

 proved to be short lived. The total yields and the amounts of dry mat- 

 ter contained are given in tables. Sulphate and muriate of potash 

 were compared on clovers. The results are given in the following 

 table:
