Abstract: Two field experiments were carried out at Mattaana Agricultural Research Station , Esna, Qena Governorate during 2000 and 2001 seasons to study the effect of weed control treatments i.e. Fluroxypur at 200 cm/fed, fluroxypur at 200 cm/fed plus one hand hoeing , hand hoeing twice and Untreated (control) under three N-fertilizer rates (80,100 and 120 kg/fed) on weeds, some agronomic characters and grain yield of Sorghum. Hand hoeing twice was the best weed control treatment in controlling grassy weeds, while fluroxypur controlled broadleaf weeds in both seasons. Hand hoeing twice gave the best control of total weeds followed by fluroxypur plus one hand hoeing in both seasons. The highest N-fertilizer at rate (120 Kg) and hand hoeing twice interaction had a significant effect on yield and yield components. All characters of yield and yield components were increased with increasing N-fertilizer rates.
