Tillering of Sudangrass (Sorghum vulgare var. Sudanense, Hitch.) with Special Attention to the Fffects of Ridging¹

Synopsis: Ridging or "earthing up" reduced the number of tillers per plant in all experiments. Its effects were mainly due to the mechanical hindrance of soil on the emergence of tillers and their consequent etiolation. Low light intensity delayed the tillering process and enhanced the effect of ridging. Nutrient deficiency reduced the number of tillers. Ridging treatments generally increased the plant height and dry weight, which was attributed to the further development of crown parts and root systems.
