EFFECT OF THE BROWN ALGA ASCOPHYLLUM NODOSUM AS BIOFERTILIZER ON VEGETATIVE GROWTH IN GRAPEVINE (VITIS VINIFERA L.)

Environmental growing farm technology involves utilization of agricultural inputs which are friendly with the

production and ecosystem. Seaweed extracts are used as biofertilizers in horticulture in special to increase plant growth

and productivity. In this study, we investigated the effect of seaweed extracts made from Ascophyllum nodosum, on

vegetative growth of Vitis vinifera cv. Feteasca Alba. We used three different concentrations of seaweed extracts to asset

the effect on fertility coefficients, shoot length, shoot diameter and leaf area. All treatments with seaweed extract

showed a stimulatory effect for studied parameters. The plants treated with the higher levels of seaweed concentrate

produced the highest absolute fertility coefficient and relative fertility coefficient relative to the plants treated with

lower concentration of or untreated control plants. Foliar spray application at different concentration of seaweed

extract of Ascophyllum nodosum influenced the vegetative growth expressed by leaf area of vine stock. The results

indicate that the 170 ml-1hl concentration of seaweed extract showed the higher enhanced of growth parameters in

grapevine.
