Varietal Photoperiodism in Sorghum

Since sorghum is indigenous to the tropics and has been grown in this country for a comparatively short time, it was thought that the longer days at the higher latitudes might offer at least a partial explanation for the unsatisfactory performance of some of the sorghum varieties introduced into Nebraska. Therefore, the object of these experiments was to determine the influence of day length on the growth and development of several sorghum varieties. Advisor: T. A. Kiesselbac
