328 EXPERIMENT STATION RECORD. 



Yellow Pearl as good ; and Ii-ene and Brocken as medium. Nilsson and Sophie 

 are considered excellent table varieties, White King a good general variety, 

 and Brocken and Gryf good sorts for starch manufacture. In a second potato 

 experiment it was observed that Up-to-Date and White King are badly at- 

 tacked by rot, while Walkiire, Stella, Svatovadavske, and President Ascher are 

 quite resistant to rot. Nilsson, Iduna, Walkiire. and President Ascher were 

 found to be prolifie table varieties, and T'p-to-Date and White King good yielding 

 general sorts. 



Baking tests with the flour of different varieties of wheat were conducted, 

 and it was determined that the best variety in the colle.'^tion was a cross by 

 Rimpau of a very early American variety with Squarehead. 



Arid farming investigations, W. M. Jardine {Utah Sta. Bui. 100, pp. 129- 

 156). — The work reported in this bulletin is with but few changes a continuation 

 of previous experiments (E. S. R., 16, p. 862). The results seciu'ed with dif- 

 ferent crops at the various farms are tabulated. In many instances wide varia- 

 tion existed from year to year with the same varieties grown upon the same 

 farms, as well as in the yields on different farms. 



In the winter wheat experiments the two complete failures recorded are from 

 2 spring varieties of durum wheat, Black Don 8232 and Pellessier 7785. These 

 two varieties, however, show great promise of developing into excellent fall 

 varieties. Turkey wheat led all other varieties tested for any one year on the 

 different farms, with a yield of 33.9 bu. per acre, and also gave the highest 

 average yield on 3 out of the 5 farms on which it was grown. Lofthouse, Gold 

 Coin, and Koffoid are popular and excellent drought resistant varieties. 



It was observed tliat the number of kernels per ounce of wheat varies mate- 

 rially with the rainfall. On the Iron County farm, where the precipitation was 

 very light, wheat showed from 10 to 20 kernels per ounce more than the same 

 varieties grown on the .luab County farm, where the average rainfall was from 

 2 to 3 in. greater, and it is pointed out tliat seeding at the rate of 2 pk.'per acre 

 of the wheat produced on the Iron County farm would probably mean as many 

 kernels per acre as seeding at the rate of 3 pk. per acre of the wheat produced 

 on the Juab County farm. The results of sowing fall wheat at different times 

 indicate that on the Iron and Washington county farms the sowing should be 

 done from September 15 to October 1, on the Juab County farm from October 1 

 to 15, and on the San Juan farm from September 1 to 15. 



Spring varieties of wheat yielded from 5 to 20 bu. per acre less than the fall 

 varieties grown under the same conditions. The leading variety according to 

 yield was Romanow, producing 26.66 bu. per acre in 1905 on the San Juan farm. 

 Mohammed ben Bashir 7792, a durum wheat, gave the best average yields for 

 the 3 years grown, 12.4 bu. per acre on the Juab farm. Other promising spring 

 varieties for dry farms are Kahla 7794. Medeah 7594, both durum wheats, and 

 William Fife, a soft wheat. 



Oats were sown about April 15 with a press drill at the rate of 4 pk. per acre, 

 and the field harrowed thoroughly two ways when the crop was about 3 in. 

 high. The plants grew from 18 to 36 in. high. Black American gave the best 

 average yield for the 3 years, averaging 31.7 bu. per acre. The best yield in 

 any one year, 36.81 bu. per acre, was secured from Sixty Day, which, however, 

 gave an average yield of only 22.62 bu. 



Among the varieties of barley, California led in average yield with 24.3 bu. 

 for the 3 years, and also produced the highest yield, 34.9 bu., in any one year. 

 California Prolific and Success also gave very good yields, and the results as 

 a whole are taken as indicating that barley can be considered one of the promis- 

 ing dry farm crops, especially where the annual precipitation exceeds 14 in.
