Effect of climate on nitrogen content of maize, barley, and red clover
1930
Delwiche, E.J. | Tottingham, W.E.
1. The contention frequently made by practical men that crops growing in northerly latitudes have a greater value as feed because of a higher protein content finds little support in these experiments. On the contrary, in the case of clover, the content of protein in the northern Wisconsin grown crop is less than in that grown in southern Wisconsin. 2. In the case of barley and of corn, the protein content is greater in the northern grown crops. Yet, from the standpoint of feed value, the difference is hardly sufficient to have practical value. 3. Judging from these tests, hays and grains of the same varieties when cut at the same period of maturity, in both northern and southern Wisconsin have little difference in feeding value. Longer trials may confirm an apparently greater content of protein, as a rule, in southern grown clover.
