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

A field experiment was conducted in Ezraa Research Station in Daraa during the seasons 2022 and 2023 to study the effect of concentration and addition method of humic and amino acids on the vegetative growth characteristics and productivity parameters of plum cultivar Al-Jawhara (P.salicina<\/em> var Black Amber). Three concentrations of humic and amin acids were tasted (1 ml\/l, 2 ml\/l, 4 ml\/l) in addition of control (without treatment), with two addition methods (Folair spray, Ground water), The experiment was factorial according to randomized complete block design (RCBD). The results showed significant superiority of Folair spray, where it reached the highest average for each of stem circumference (21.43 cm), length of the shoots (139.07 cm), leaf area (37.77 cm2<\/sup>\/leaf), fruit set % (5.64%), ripe fruits number (800.27 fruit\/tree), The average of fruit weight (70.14 g), one fruit size (63.18 ml), the highest value of tree productivity (56.71 kg\/tree), and per donum (2.83 ton\/d). The amino acids treatment at 4 ml\/l concentration alone or with humic acid at 4 ml\/l concentration achieved a positive effect in improving the vegetative growth characteristics (stem circumference, length of the shoots, leaf area) and fruiting characteristics (fruit set percentage, ripe fruits number, weight and size of one fruit, yield per tree, and yield per dunum) significantly superiority to the rest of the treatment including the control. Regarding the interaction effect between concentration and addition method of humic acid and amino acids, the highest values of stem circumference (22.01 cm), fruit set percentage (6.33 %),\u00a0 ripe fruits number (876.9 fruit\/tree), one fruit size (84.66 ml), tree yield\u00a0 (71.6 kg\/tree), and unit area yield (3.58 ton\/d) were achieved when the foliar spray treatment of amino acids at 4 ml\/l\u00a0 concentration, while the highest values of length of the shoots (154 cm), leaf area (45.33 cm2<\/sup>\/leaf), one fruit weight (84.4 g) were recorded when foliar spray treatment of amino acids and humic acid at 4 ml\/l\u00a0 concentration for both of them, while the lowest values were achieved in the control treatment.<\/span><\/p>\n
