plants are too close together to be separated. There is also some 
apparent crowding out of weak plants. The number of plants 
counted per peck of seed sown ranged from 80.500 in the 10-peck 
seeding to 98,500 in the 4-peck seeding. The ratio of grain to straw 
was almost 1 to 1 except in the 8-peck seeding.

EXPERIMENTS WITH BARLEY. 
The yields of the best varieties of barley in pounds per acre on 
the Belle Fourche Experiment Farm have been nearly as large as 
those of oats and spring wheat. Most varieties of barley mature more 
quickly than oats or wheat, and the crop can thus be sown at a later

date. Barley grown on the dry lands of western South Dakota is 
used almost exclusively as a feed crop and its market value is of 
minor importance there. 
Winter barley has been sown several years, but has never survived 
the winter at Xewell.
