CEKEAL EXPERIMENTS ON THE CHEYENNE EXPEEIMENT FAEM. 11 



were grown in triplicate tenth-acre plats. In 1915 the wmter-wheat 

 varieties were grown in triphcate thirtieth-acre plats and most of 

 the spring cereals in duphcate twentieth-acre plats. 



PREPARATION OF THE LAND. 



In the preparation of the seed bed the aim at Archer has been 

 to do the work in as practical a manner as possible. However, at 

 tunes the land has probably been given better preparation than 

 would be profitable on the average farm. 



XW crops were grown on breaking in 1913 and on fallow land in 

 1914. In 1915 the winter wheats were grown on fallow and all 

 spring crops on land which had produced corn the previous year.

HATES AND DATK.S OK SEEDING. 



lu the varietal experiments at Archer, winter and spring wheats 

 have been seeded at the rate of 3 pocks per acre. The smaU-kernelcd 

 early oats have been sown at tlic rate of 4 pecks, and the larger 

 kemeled midseason varieties at the rate of 5 pecks per acre. Barley 

 has been sown at the rate of 4 pecks and flax at 15 pounds per acre. 



Winter wheat, except in the fall of 1912, has been seeded between 

 September 1 and 15. Sf)ririg wheat, oats, and barley have l)een
