Effect of Drip Irrigation Levels and Emitters Depth on Okra (Abelmoschus esculentus) Growth
A.R. Al-Harbi, A.M. Al-Omran and F.I. El-Adgham

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 (T1), 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 10.29 t ha-1 in 2006 and for D1 treatments were 10.8 t 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.

It is a useful information about drip irrigation. I am a farmer and we have very large fields, before drip
irrigation system was found it was a nightmare to irrigate all those fields because where i live is a place
that does not rain so much. Now we use drip irrigation, saving so many water and it is a lot easier to irrigate
the field with that. I am trying to read everything about drip irrigation and i recommend every farmer to use that
technique, so i am grateful for everyone who gives information about it. I also found a very good guide about drip
irrigation and it may be useful too for those who want to learn more information about that;
