Abstract:\u00a0<\/strong><\/span><\/p>\n

The research was carried out in an olive orchard belonging to the General Commission for Scientific Agricultural Research (Hama Research Center) during the two seasons (2020-2021) with the aim of studying the effect of different levels of conventional and Nano-fertilizers on the productivity of the olive tree (Kaisi cv.) and its oil content. The experimental trees were chosen to be as homogeneous in growth and age as possible. Traditional nitrogen fertilizers were added according to the following parameters: K (control without fertilization), T100<\/sub> (according to the previous fertilizer recommendation of the Ministry of Agriculture at 555 g\/tree), T75<\/sub> (25% less than the fertilizer recommendation at 416 g\/tree), T50<\/sub> (less Of the 50% fertilizer recommendation, 278 g\/tree), T125<\/sub> (25% more than the 694 g\/tree), T150<\/sub> (50% more than the 833 g\/tree), and Nano-fertilizers were added according to the following parameters : N10<\/sub> (10 g\/tree), N20<\/sub> (20 g\/tree), N30<\/sub> (30 g\/tree), N40<\/sub> (40 g\/tree), and phosphate and potassium fertilizers were added to all previous treatments according to the approved fertilizer recommendation and at a fixed rate, and the experiment was designed. Completely randomized block method, with three replicates for each treatment. The results showed that the greater the amount of traditional nitrogen fertilizer (urea) than the 25% fertilizer recommendation in the treatment (T125<\/sub>), the productivity increased to (33.67, 41.47 kg\/tree) in both seasons and without a significant difference with the treatment N40<\/sub> (40 g\/tree) Nano-nitrogen fertilizer. Which also excelled in terms of oil percentage, reaching (20.25 and 21.12%) respectively.<\/span><\/p>\n
