Cultural Problems With Grain Sorghum

The problems related to grain sorghum (Sorghum vulgare Pers.) production are becoming increasingly important to farmers in Tennessee, as well as in other areas of the Southeast. However, the considerable experimental work that has been done on this subject has been confined largely to areas of the more arid Southwest. This information is of comparatively little value to farmers of the Southeast because of the differences in climatic and edaphic conditions. In view of the scarcity of information on these facts, and the increasing importance of grain sorghum in Tennessee, the relationships among row spacing, planting rate, and plaiting date as they might affect grain yield, plant height, and number of days to mid flowering were studied in the investigation herein reported.
