Afield 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 yield components growth and yield 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 number of panicles/m2 , number of grains per panicle, 100-seed weight and final grain yield (t/ha). The results showed that, the tillage and manure had significant effect on yield and yields attributes measured. Tillage depth (15 cm) was highest in highest in number of panicles/m2, number of grains per panicle and final grain yield (t/ha). Concentration manure of 24 t/ha were superior in grain yield. Tillage and manure had no significant different in 100- grain weight. Black gardoud soil had higher grain yield (1.96 t/ha) than red soil (1.75 t/ha).
