At present, there is a growing consumer interest in high value-added vegetable products. It is therefore necessary to limit the use of fertilizers and synthetic chemical pesticides because of the harmful effect on the environment. In this regard, a melon culture was established in the polyethylene tunnels to which Lignohumat biostimulator product was applied in vegetation as an alternative for chemical foliar fertilization. It is a humic product, granulated with microelements and with the effect of growth and protection against stress factors. Three treatments were applied in three doses of fertilization. The specific of variants was: V1 (Control)-unfertilized; V2-fertilized with 100 g/ha; V3- fertilized with 150 g/ha; V4-fertilized with 200 g/ha. The determinations focused on the quality of the production. The 200 g/ha Lignohumat dose influenced the quality attributes and the dose of 100 g/ha Lignohumat the antioxidant activity of fruit. Thus, was recorded a SUS content of 8.05%, SUT of 12.29%, reducing sugars of 3.73%, vitamin C of 29.4 mg/100 g, TP of 42.03 mg GAE/100 g, carotene of 20.98 mg/100 g f.w. and antioxidant activity of 184.44 μMTE/100 g.
