A field experiment conducted in North Kordofan state of Sudan for two successive rainy seasons (2007/08- 2008/09) to investigate the effect of tillage and farm yard manure on vegetative growth indices of sorghum (Sorghum bicolor L. Monech) in gardoud soil (Red and black). The treatments consisted of three tillage depth (0, 15 and 25 cm) and five concentrations of manure (0,6,12,18 and 24 t/ha). Split plot design with four replications was used. Character studied were plant height, stem diameter, number of nodes per plant, plant density. The results showed that, the tillage and manure had significant effect on most growth measured. Tillage depth (15 cm) was highest in stem diameter, number of nodes per plant and plant density. Concentration manure of 6 and 24 (t/ha) were superior in growth indices of stem diameter and number of nodes per plant. Tillage and manure had no significant different in number of tillers and. Generally black gardoud soil had higher vegetative growth than red soil.
