Stete. Tlio details of tlioso ('xpcriiiiciits arc not yet ready for publi- 

 cation, but the followiuii- bi-icf snunuiu'v of th(^ residts thus far ob- 

 tained is given : 



( 1) On stei'ile lands both nilrou'en and phosi)horic acid must be 

 present in a fertilizer, the nitrogen in relatively lar<>-e proportion, in 

 order to produce any beneficial eH'ect upon the crop. 



(-2) On soils of niediuni fertility nitrogen (in niti-ate of soda) 

 seems to produce a more marked effect than ])hosi)horic acid, yet both 

 seem to be essential. 



(3) On soils cai)ab]e of prochicing :',0 to 40 bushels of wheat to the 

 acre with good tillage alone, we have failed to gain any increase of 

 crop l)y the use of any fertilizer or combination of fertilizers. 



(4) Potash seems to be less often required than either nitrogen or 

 phosphoric acid. We have thus far failed to gain any increase on 

 any soil from the use of potash alone, but it has sometimes produced 

 a slight increase when added to nitrogen and phosphoric acid. 



COMPARA'IIVK TEST OF VAIUI:T]P:S OF WHEAT, J. F. HiCKMAX, M. A. S. 



(pp. 1-21-1H12).— " Previous to the fall of 1888 the ' south field ' (about 

 16 acres) had been used for six successive seasons in variety and cul- 

 tural tests of wheat. The plats nsed Avere of various sizes, most of 

 them being one thirty-second acre in size, and were laid out so that 

 they \\ere drilled north and south. A diagram represents the field as 

 rejilatted in the fall of 1888. Most of it was laid out in tenth-acre 

 plats, ruiniing east and west. These plats are IG feet wide by 2T2t^ 

 feet long, and are separated by spaces 2 feet wide. * * * On one 

 section, however, nearly three hundred differently named sorts of 

 Avheat are grown in plata about 5 feet square. The results of this 

 work will be discussed in a subsequent article.'*' 



The results of comj^arativc tests of 9G varieties in 1889 are given in 

 tabular foi'ui. Another table contains a compilation of results of 

 tests of ()T varieties for nine years, showing the yield of each variety 

 for each year that it has been grown at the Station, and also the aver- 

 age yield for the period during which it has been grown here. A 

 third table gives the yearly and ax'erage yield of IT varieties grown 

 at the Station for five years. 



Synonyms. — '" Eed Fultz and Poole b;'ar a close resemblance to the 

 old Michigan Amber. Ivoyal Australian seems to be the old Clawson 

 under a new name. Diehl-Mediterranean is also called Hybrid ]Medi- 

 terranean. and appears to be synonymous with IJaub's Black Prolific, 

 Missouri Bhie Stem, Brady Lake, Seneca Ohief, Michigan Bronze, 

 Andrews" No. 4. Sibley's Hybrid, and (ilolden Cross. Silver Chaff, 

 ^Martin's Amber, and I^tindrcth are probably one \ariety. Tasmanian 

 Ived bears a close reseniblan.ee to Mediterranean, and Finlev and Rice 

 seem to be scarceh^ variations of Fultz.'' 



Bearded vs. smooth, and red vs. lohite ivheats. — " In averaging 

 the yields for 1889 we find that thirty-one varieties of bearded 

 wheat give an average of 40i bushels per acre, while the thirty-six
