The chemical analysis was carried out in the laboratories of Faculty of Agriculture, Damascus University. The study contains 9 treatments and the data was calculated using Simple Random Design. The combination treatment of humic acid (10 g\/l) and yest (6 g\/l) resulted in the best morphological parameters (57.06 cm, 3.50, 150.54 cm\u00b2 for plant height, stem number\/ plant and leaf area respectively), physiological parameters (22.24 %, 17.25 %, 8.77 % for dry matter, starch, total soluble solids, respectively), and productivity parameters (3.03, 225.07 g, 30.32 ton\/ hectare for tubers number\/ plant, tubers weight, productivity). The lowest values for all studied parameters, however, were obtained in control plants.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Key words:<\/strong> Potato, Sponta, Humic Acid, Yeast, Growth, Productivity.<\/span><\/p>\n<p><strong><span style=\"font-family: 'times new roman', times, serif;\">Full Paper in English: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v12n2p9.pdf\">pdf<\/a><\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Roula Bayerli (1)* (1). \u00a0Department of Horticulture Science, Faculty of Agriculture, Damascus University, Syria.
