"Fall irrigation in 1891, when tbe ram brongbt the grain all up, was detrimental 

 to liotli yield of grain and straw, wbile in the succeeding fall, when there was not 

 rain enough to bring the grain up till late, the fall irrigation was beneficial, the 

 average being a little in favor of the fall irrigatiou. The increase over no irrigation 

 is not enough to justify the expense of fall irrigatiou. It would appear, too, that 

 2 irrigations in tbe spring is about the proper aniouut of water to give fall grain on 

 exceedingly dry ground. . . . It seems that a good fall wheat might save 2 irriga- 

 tions and give the same returns as our spring wheat is doing." 



Experiments with wheat and barley, R. H. Miller and E, H. 

 BiJiNKLLY {Marijland Sta. Bui. J^s, pp. 137-149). — Taking the average 

 results for 1893 and 1894, the following were the most prolific varieties 

 of wheat: Fultz (yielding 44.4 bu. per acre), Garfield, Valley, Wis- 

 consin Triuini)h, Badger, and Currell Prolific. 



The yield of wheat following a crop of cowpeas turned under August 

 17 was 39.8 bu. ; that following- crimson clover sown March 30 and 

 plowed under July 19 was 41.3 bu. per acre. 



On a plat which had been limed for the preceding- crop of corn, wheat 

 yielded at the rate of 31.3 bu. per acre. On a check plat which had 

 not been limed the yield was 22.8 bu. of wheat per acre. Nitrate of 

 soda applied April 14 did not increase the yield of wheat which had 

 been fertilized in the fall, but increased by 7.7 bu. per acre the yield of 

 wheat which had not been fertilized in the fall. 



In a comparison of the yields of wheat and barley the yield of wheat 

 was 30.7 bu.; of winter barley, 50.5 bu.; of 2-rowed spring barley, 24.2 

 bu., and of Crowed spring- barley, 29.2 bu. 



Experiments in rolling and hoeing -wheat, J. W. Sanborn ( Utah 

 Sta. Ept. 189.J, pp. 139-150). — The difterence between the yields of 

 wheat on plats rolled and unrolled was slight. Soil temperatures and 

 percentages of moisture in the soils of rolled and unrolled plats are 

 tabulated. '' It seemed that the unrolled area had a lower temperature." 



Wbeat not hoed yielded 15.5 bu. per acre; hoed 1 in. deep, 12.58 bu.; 

 hoed 2 in. deep, 13.44 bu.; hoed 3 in. deep, 9.61 bu. ; and hoed 4 in. deep, 

 9.75 bu. Determinations of soil temperatures and moisture on plats 

 hoed at different dejiths are tabulated. 



Time of harvesting wheat, J. W. Sanborn ( Utah Sta. Rpt. 1S93, 

 pp. 164-16(i). — The average resnlts for 4 years were as follows: When
