Water is the physical basis of life in the living organism. Water is required by plants for the manufacture of carbohydrates and as a means for transportation of foods and mineral elements. The present study was undertaken to examine the effect of watering regime on early growth of Acacia senegal (LINN) Willd provenances at Usmanu Danfodiyo University (UDU), Sokoto. Seeds from four provenances (Yobe, Borno, Kano and Jigawa) were sown in a randomized complete block design with 4 replicates each. Seedlings were monitored under 4 different watering regimes (once daily, twice daily, once in 2 days and once in 3 days) and growth parameters were measured forthnightly for 12 weeks. The result indicated that, Yobe and Borno provenance performed better when watered once in three days. Jigawa and Kano Provenance also showed good growth performance when watered once in two days, and this reflects the capability of these species in coping with the drought stress. The Study therefore recommends that watering of A.senegal seedlings once between two to three days should be adopted in the semi-arid zone, since it ensures proper growth performance of this species.
