Abstract: Okra Abelmoschus esculentus (Climson Spineless CV.) growth, rooting, yield and water use efficiency were evaluated in a field trial, where four irrigation rates at 60 (T,), 80 (T2), 100 (T3) and 120% (T4) of the estimated evapotranspiration (ETo) and four drip irrigation emitters depth: surface 0.0 m depth (D0), sub-surface at 0.15 m depth (D1), at 0.25 m depth (D2) and at 0.35 m depth (D3) were imposed following a split-plot in a randomized complete block experimental design with three replications in 2005 and 2006 seasons. Vegetative growth characters (plant height, number of leaves, shoot fresh and dry weight), rooting (weight, length, width and root/shoot ratio), early and total yields were measured. Marketable Total Yield (MTY) increased significantly with the increase of irrigation level in both seasons. MTY for T3 treatments were 14.32 t ha-1 in 2005 and 10.291 ha-1 in 2006 and for D! treatments were 10.81 ha-1 in 2005 and 9.75 t ha"1 in 2006 season. The Crop Water Use Efficiency (CWUE) ranged from 1.45-2.93 kg m"3 and 1.29-2.43 kg m"3 in 2005 and 2006, respectively. MTY increased significantly as emitter depth increases from surface to 0.35 m in both seasons. Crop Water Production Function (CWPF) was done on the results. It reflects the beneficial of applied water in increasing yield. The CWPF was represented by quadratic polynomial equations.
