Scope of Using Treated Olive Mill Wastewater in Tomato Production

Abstract An experiment was carried out to evaluate the feasibility of using treated olive mill wastewater (OMW) in irrigating tomato crops. The OMW was filtrated using a home-made filter of a matrix that mimics nature. OMW filtration improved physical and chemical properties of the filtrate as it became clear with neutral pH. The results showed that the 10% dilution of the filtrate gave best results compared with those irrigated with tap water. The 20% dilution gave the second best outcome followed by the 50% which gave an intermediate plant growth and production. Irrigation with untreated OMW killed the plants in a couple of days. Treated OMW was found to be useful in irrigating tomato crops at economic level.
