Abstract:
>This research was conducted at the Agricultural Scientific Research Center in Latakia/General Commission for Scientific Agricultural Research (GCSAR) in 2018/2019, to study the effect of Olive Mill Wastewater (OMWW) irrigation on the growth and yield of Quinoa crop. The experiment included five treatments which were investigated in a Randomized Complete Block Design (RCBD) with five replications in a greenhouse pot: T0 represents the control treatment using water only, T1 represents using 3% of untreated OMWW diluted with water, T2 represents using diluted 5% of untreated OMWW, T3 represents using diluted 3% of anaerobically treated OMWW, and T4 represents using diluted 5% of anaerobically treated OMWW. The addition of Phosphate Solubilizing Bacteria (PSB) to OMWW, with no dilution, was adopted for the application of anaerobic treatment, which was performed using a laboratory designed digester. Quinoa pots were watered periodically according to the treatments applied. At the end of the growing period, Quinoa was harvested and several indicators were compared, including: plant height (h), flower length (l), total number of crop seeds (n), total weight of crop seeds (w) and weight of 1000 crop seeds per plant (w1000).The results showed the superiority of T0 in terms of (h) and (l) compared to other treatments, followed by T4.On other hand, T4 outperformed T0, in terms (n) and (w). In terms of (w1000), the results showed that T0 outperformed all the treatments, followed by T3, T4, T1 and T2. The statistical analysis showed that there was no significant difference between T0 and T4 treatments for all the studied measurements.
Key words: Olive Mills Wastewater (OMWW), Quinoa, Irrigation, Phosphate Solubilizing Bacteria (PSB).
