The study aimed to evaluate the effects of irrigation water salinity on the growth of mango seedlings (Timor cultivar) and to assess the effectiveness of humic acid and potassium silicate in mitigating salinity stress and improving seedling growth and soil characteristics.<\/p>\n

The findings revealed that increasing irrigation water salinity led to reduced vegetative growth of the seedlings and increased salt accumulation in both the soil and plant tissues. In contrast, the application of potassium silicate and humic acid, either individually or in combination, significantly improved plant growth, enhanced nutrient uptake efficiency, and alleviated the adverse effects of salinity stress. The combined treatment produced the best results under moderate salinity levels.<\/p>\n

The study recommended relying on irrigation water without additives under low-salinity conditions to reduce costs and avoiding the use of highly saline water without applying ameliorative treatments. It also recommended foliar application of potassium silicate at a concentration of 1.5 g\/L<\/strong> combined with humic acid at a concentration of 2 g\/L<\/strong> under moderate to high salinity conditions, due to its effectiveness in improving seedling growth, increasing nutrient uptake efficiency, and mitigating the effects of salinity stress.<\/p>\n

The defense session was attended by a number of academics, researchers, students, colleagues, and the researcher\u2019s family.<\/p>\n
