Changes in mechanical and plant technology: the Corn Belt, 1910-1940
1983
Bogue, A.G.
Extract: During the period 1910-1940 some changes were occurring in the production practices of the Corn Belt. Three of the most important were the substitution of the tractor for horse power, the introduction of hybrid seed corn, and the development of viable mechanical picker-huskers for harvesting corn. This paper examines the background of those innovations, evaluates current assumptions about them, presents data concerning the relative per acre savings or additional income involved in adoption, and notes the possibility that assumptions about the economic rationality involved in corn improvement research, as well as the implications of the "dry hole effect," may require some revision.
