Abstract
This work is aimed at monitoring the interaction effect among soil organic fertilization, the best suitable irrigation water scheduling under modern irrigation system and maximizing olive production under the dominant drought and water scarcity conditions in both Egypt and Tunisia. The study is conducted to evaluate the interaction effect of soil organic fertilization, (compost rates of 5, 10 and 15 Ton/fed), and suitable irrigation water scheduling by 70%, 80%, 90% and 100% quantities calculated from penman - monteith equation under the modern irrigation system, (i.e. surface and sub-surface drip irrigation systems in one and two laterals) on maximizing olive (Olea europacal) production grown in Egypt and Tunisia. The obtained results could be summarized as follows: Percentages of fruit flesh weight to initial were significantly the highest (90.90% and 90.66%) when trees received annual water quantities that were equivalent to 100% ETc to both considered seasons.2. The highest yield values were 52.50, 55.84 and 58.50 kg/tree for the first season while they were 48.80, 55.60 and 57.10 kg/tree for the second season under irrigation water scheduling 100% when applying surface drip irrigation with the compost rates of 5, 10, 15 ton /fed., respectively. 3. WUE values surpassed under sub-surface drip irrigation system. 4. Concentration values of the nutrient ”N” was as high as the largest amounts of irrigation water 100% and a higher rate of compost i.e., 15 ton/fed.5. The highest ”Ca” and ”Fe” concentration values were higher in the second season comparing to the first season.6.The percentages of carbohydrates or protein were as high as the largest amounts of irrigation water 100% and a higher rate of compost i.e., 15 ton/fed., while they decreased with minimal amounts 70% and a lower rate of compost application, i.e. 5 ton/fed. Furthermore, it was noticed that surface drip irrigation system with two laterals surpassed to one lateral as a good water management. 7
