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

The research was carried out at Al-Hanadi Research Station of Lattakia Agricultural Scientific Research Center during 2019-2020 , to study the effect of humic acid HA ( from Humantic \u2013Company-Germany) application (500, 1000 and 1500) ppm ,on Spunta potato growth and productivity at two levels (80% and 40% ) of the field capacity under greenhouse conditions. The experiment included 8 treatments repeated 3 times. The experiment design used a split plot system. After 35 days of planting, plants were sprayed with humic acid three times with an interval of ten days . The results showed a decrease in some vegetative and productive indicators at 40% level than at 80%. The lack of irrigation decreased plant height and the number of leaves and plant production (kg \/ plant) without affecting leaf area. Humic treatment at 1000 ppm gave the highest rate of photosynthesis (0.199 g \/ cm2 \/ day) at 40%level of field capacity . The highest number of leaves (25.125) leaf \/ plant and leaf area were recorded at 80%. Stem height, relative water content in leaves (64.93%), and photosynthesis rate increased with 1500 ppm at 80% level. the highest productivity (2.66) kg \/ m2 achieved at humic 500 ppm at 80%. Whereas, the best HA used efficiency was at 1000 ppm under water stress.<\/span>
