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

 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 Newell.
