One plot in each area was seeded in mid-December and one about 

 March 25, without any working of the soil. Only a few stray plants of 

 sweet clover resulted. (Purnell Fund.) 



Variety Tests of Legumes 



A half acre of the Heater lot on the University farm was laid off by 

 F. S. Prince into eightieth-acre plots in 1926 and seeded to different 

 varieties and strains of alfalfa and sweet clover and to red clover and 

 sweet clover from different sources. 



The plots were observed in 1927 for thickness of stand, winter kiUing, 

 and general habits of growth. 



The alfalfa varieties rank for 1927 in the following order: Ontario 

 Variegated, Cossack, Hardigan, Grimm. Grimm seemed to be the only 

 variety which suffered from winter killing, and that only slightly. 



Sweet clover seedings were made as follows: Yellow and White Blossom 

 from Canada, White Blossom from Michigan, Ohio, and Alabama. 



There was no winter-kilhng in any of the sweet clover plots; the only 

 difference observed was that the farther north the source of the seed, the 

 earlier was the maturity. As between Canadian White Blossom and 

 Alabama White Blossom sweet clover, this difference appeared to be about 

 ten days, a variation that has held throughout the season. 



Plots were sowed with red clover seed from Poland, Germany, Minne- 

 sota, Chile, Michigan, Hungary and France, obtained from the United 

 States Department of Agriculture. The only strain which suffered from 

 winter killing was that from Poland. 



All the plots in this test were in duplicate, limed at the rate of two and 

 one-half tons per acre, and fertilized with 500 pounds of acid phosphate 

 per acre. (Hatch Fund.) 



EFFECT OF SICCATIVES ON VITALITY OF SEEDS " 



If potato seed is cut in advance of planting and sacked, the stand 

 obtained will be better if the pieces are freely dusted with sulphur before 

 being bagged, finds 0. Butler. 



Tubers of certified seed were carefully halved along the major axis and 

 each half was cut into seed pieces. One lot was dusted with sulphur and 

 sacked, and the other lot was sacked without treatment. Both lots were 

 placed in storage in a dark cellar at 15.9° C. for four days and planted. 

 The seed that was sulphured produced 2.9 per cent weak hills, the non- 

 treated seed 4.48 per cent. (State Fund.)
