CEREAL EXPERIMENTS AT THE WILLISTON SUBSTATION.

was broken in June of the previous year. After breaking to a depth 

 of 6 inches, the ground was disked and harrowed and kept free from 

 weeds during the remainder of the season. 



In 1911 the varieties were grown on ground that produced a corn 

 crop the previous year. In 1912 the plats were on breaking, as in 

 1909 and hi 1910. In 1913 and 1914 they were on summer-fallowed 

 ground. 



In the spring of each year the ground was worked sufficiently to 

 put it in good condition for seeding. It was disked when necessary 

 and was harrowed two or more times. In the case of fallow, harrow- 

 ing or disking was done frequently enough to keep down all weed 

 growth throughout the season. The plats were given no further cul-

TREATMENT OF CROPS. v 



The seeding lias been done with a double-disk 8-foot drill with a 

 6-inch spacing between the disks. The wheat and oats were seeded 

 usually during the last part of April, and the barley and flax somewhat 

 Later. With the exception of flax, which should not be sown very 

 deep, I lie small grain-, were seeded from 2 to 3 inches in depth. The 



seeding in each ease was at the rate which was considered best for 

 the locality. 



After the crops headed they were freed from mixtures by roguing. 

 The cutting was done with a binder and the bundles placed in shocks, 



where they remained until thrashed. Thrashing has heen done with 



mall eparator with a L2-inch cylinder. Great care was used to 

 avoid the mixing of varieties in harvesting and thrashing.
