tons per acre, ami each of these made about .i tons. In a seed test 21 varieties 

 were gi-own and the range of yield was from !t bu. of seed for Early (Jreen to 

 32.1 bu. for No. 19180. Seven varieties produced 20 bu. or over and only two 

 fell below 12 bu. 



Brief notes are given on tbe yield of miscellaneous forage crops, including 

 millets, rape, buckwheat, Kafir corn, and sorghum. The results of top-dressing 

 meadows with cijuimercial fertilizers show the greatest i)rofits from the use of 

 160 lbs. of nitrate of soda, 320 lbs. of acid phosphate, and 80 lbs. of nniriate of 

 potash i)er acre. Practically the same profits were secured from the use of 240 

 lbs. of nitrate of soda and 320 Ib.s. of acid i)hosphate jter acre as from the use 

 of 320 lbs. of nitrate of soda, 320 lbs. of acid phosi)hate, and SO lbs. of nniriate 

 of i)otash per acre. 



Results of cooperative tests of varieties of corn, wheat, oats, soy beans, 

 and cowpeas. 1907, A. T. Wiancko and ('. O. Cromer {Iiidiitnii ,^ta. But. 12.'i, 

 pp. :i5-(;0}. — The work here reported is in continuation of experiments previ- 

 ously noted and described (E. S. R., 18, p. 925). This year the experiments 

 were conducted <m about 650 different farms throughout the State and included 

 078 tests of 4 to 5 varieties each. There wei'e 415 tests of 4 to 5 varieties of 

 corn, 75 of 5 varieties of winter wheat, 55 of 5 varieties of oats, 62 of 4 vari- 

 eties of soy beans, and 71 tests of 4 varieties of cowpeas. The results secured 

 by the diffei'ent experimenters are shown in tables. 



The backwardness of the season seriously affected the results of the experi- 

 ments in many cases and much immature corn was reported. In sections 1 and 



2 the average of the reports showed the order of maturity to be as follows: 

 Early Yellow Dent, Cook Yellow Dent, Dunn Yellow Dent, and Anson White 

 Dent, the difference between the first and last being about 10 days. In sections 



3 and 4 of the State, Early Yellow Dent was fully 2 weeks earlier than the 

 three other varieties with which it was compared. In section 5 Golden Dent 

 ripened first, being followed by Riley Favorite, Reid Yellow Dent, Leaming, and 

 Boone County White, all varieties rii)ening within a period of about 10 days. 

 In section 6 Reid Yellow Dent was the earliest, and in section 7 Golden Dent, 

 Reid Yellow Dent, Learning, Boone County White, and Pride of Indiana ripened 

 in the order mentioned, Golden Dent ripening about 3 weeks earlier than Pride 

 of Indiana. In section 8 the yellow varieties apparently were only 4 or 5 days 

 ahead of the white. In sections 9, 11, and 12 the order of maturity was prac- 

 tically the same, the rank being Golden Standard, Johnson County Yellow, Pride 

 of Indiana, Johnson County AVhite, and Vogler White Dent, the difference be- 

 tween the first and the last being a little over a week. In section 10 Reid Yel- 

 low Dent ripened first, being followed by Golden Staudai'd, Pride of Indiana, 

 Johnson County White, and Vogler AVhite Dent, the first riiieniug about 2 weeks 

 earlier than the last. 



The results of tests with winter wheat varieties showed that Michigan 

 Amber was a little superior in yield. Dawson, Golden Chaff, Abundance, New 

 American Banner, Mealy, and Rudy have also given good results. 



The experiments with oats showed that Great Dakota, Silver Mine, and Czar 

 of Russia are quite similar in appearance and habits of growth. National and 

 Swedish Select have a plumper grain and are better than average yielders. 

 Early Champion was found to be a week or 10 days earlier than the other 

 varieties. 



The yields f)f varieties of soy beans showed important differences. Dwarf 

 Early Yellow, Ito San, and Early Brown, which are very similar in their gen- 

 eral characteristics, ripened from September 10 to 15, or about 115 days from 

 planting. No. 12399 ripened in about 130 days and was found to be a good 

 vielder both in grain and forage. Medium Early Yellow matured in about 150
