FIG 2-Average SPAD after 36 days from transplanting in the two compared treatments. The SPAD index measures the chlorophyll content in leaves, therefore proving their health status. Plants with a higher content of chlorophyll and superior photosynthetic efficiency have a stronger resistance against biotic and abiotic stress. Vigor L Rapido favours a bigger SPAD value compared to the Control.

cS FIG 6 - Volume index of roots in the two compared treatments. The use of Vigor L Rapido results in a superior fresh weight, dry matter and volume of the roots. Plants with more vigorous roots are stronger against biotic and abiotic stress, exploring a wider portion of rhizosphere and better exploiting the elements applied with fertilizers.

The use of Vigor L Rapido results in an increased vigour of lettuce, even in conditions of water and saline high stress. The use of Vigor L Rapido results in a superior vigour and SPAD, thus resulting in bigger yields and in a better phytosanitary status, even under water and saline stress.

Experimental results Zucchiniin growth chamber MATERIALS AND METHODS Vigor L Rapido increases the number of flowers per plant compared to the not treated Control, thus resulting in a higher GSP.

Vigor L Rapido increases the fresh weight of plants compared to the Control. The action of brown seaweeds results in bigger yields. Vigor L Rapido also increases the dry weight per experimental plot compared to the Control, thus allowing a better use of the fertilizers. Vigor L Rapido increases roots length and volume index. A longer and voluminous roots system makes the plant stronger against biotic and abiotic stress.

Experimental results Tomato cropsin growth chamber MATERIALS AND METHODS FIG 1 - Fresh weight per plot in the two compared treatments. The use of Vigor L Rapido is apt to achieve a gain in fresh weight compared to the not treated Control. Seaweeds, vitamins and amino acids positively influence cell development and yields.

FIG 2 - Dry weight per plot in the two compared treatments. The seaweeds contained in Vigor L Rapido allow to obtain an increased dry weight per plot compared to the Control. The biostimulant action of the product allows a better absorption of nutrients and a healtier status of the plant. The biostimulant action of Vigor L Rapido increases the root growth with a consequent larger soil exploration. That's because the roots volume of the not treated Control is smaller than the one of the biostimulated plants. Vigor L Rapido increases the content of dry matter in roots. Such roots with a higher...

1,6 FIG 2-Average plants width in the two compared treatments. Vigor L Rapido increases both width and height of plants compared to the not treated Control, also improving leaves quality and photosynthetic efficiency (SPAD).

Fresh weight (roots) FIG 5 - Average fresh weight of roots in the two compared treatments.

Vigor L Rapido increases both the vegetative and reproductive development, as well as the roots growth. This proves that plants with a good hair-root balance have a better phytosanitary status. In fact, deeper and more voluminous roots are able to explore a wider portion of rhizosphere and to absorb nutrients in a more efficient way with a stronger resistance against biotic and abiotic stress.

FIG 8 - Fresh weight of fruits in the two compared treatments. FIG 9 - Dry matter of fruits in the two compared treatments 15230,2 FIG 10 - Average yields in the two compared treatments. Vigor L Rapido positively influences yields values, namely size, fresh weight and dry matter of fruits.

Experimental results Olive treesin open field MATERIALS AND METHODS FIG 1 - Yields per plant in the different compared treatments. The use of Vigor L Rapido results in increased yields per plant (kg) proportionally with the doses supplied, even at low dosage. The seaweeds contained in the product favour a better absorption of soil substances after NPK fertilizations. Besides, they also promote a superior roots development and so more vigorous plants, with a better phytosanitary status.
