Dynamic brings an increased plants vigour, according to the dosage. The plant shows maximum values of vigour with a dosages of 15 1/ ha. More vigorous plants are stronger against biotic and abiotic stress, achieving both a higher photosynthetic efficiency and an improved rooting activity. The values of SPAD prove the phytosanitary status of crops. Higher values suggest a better resistance against biotic and abiotic stress, with higher photosynthetic efficiency levels and bigger yields. SPAD values may increase proportionally to the dosage of Dynamic.

The NDVI value shows if the plant is under stress conditions depending on the color of its vegetative part. Crops with a higher parameter are more vigorous and obtain bigger yields. NDVI values may increase pr Height with stress The use of Dynamic, even under water stress (W1: CIC 50 %), results in a higher crops growth compared with plants getting an 85% water capacity. Amino acids of plant origin give better health conditions also to those crops under stress. Dynamic shows remarkable results even at low supplied quantity. However, the best dosage of such biostimulant (with or without stress)...

Romana x 3 water stress levels 11 12 13 = no stress / medium stress / high stress The use of Dynamic results in an increased plants vigour compared to the not treated ones. Such information confirms its biostimulant activity through a bigger production.

Dynamic results in a higher chlorophyll content, thanks to the carotenoids increasing both photosynthetic efficiency and phytosanitary conditions. Dynamic results in a remarkable increase in plants fresh weight, confirming its biostimulant action.

FIG 6 - Roots volume index between 1 and 5, after 62 IMG 2 - Roots of lettuce crops in the two compared days from transplanting in the two compared treatments, treatments under standard conditions. The use of Dynamic results in increased fresh weight, width and root volume index, thanks to the bioactive substances which stimulate rooting. Plants with a more expanded and deeper root system have a stronger resistance against biotic and abiotic stress, exploring a wider portion of rhizosphere and better exploiting the elements applied with fertilization.

Data proves that the use of Dynamic favours an increased vigour compared to the Control, even without any water and saline stress, thus bringing benefits for production, both under stress and in standard conditions. The SPAD value is higher with water and saline stress when we use Dynamic. This results in an improved photosynthetic efficiency.

FIG 13 - Roots fresh weight in the two compared treatments in standard conditions (SO and 10) and high electrical conductivity (5 ds/m and high stress).

FIG 14 - Roots dry matter in the two compared treatments under standard conditions (SO and 10) and high electrical conductivity (5 ds/m and high stress). Dynamic results in an increase of dry matter compared to the not treated Control, even with water and saline stress. The above experimental tests prove that Dynamic brings the following important benefits to plants: BIOSTIMULANT ACTIVITY even at low application doses ANTISTRESS ACTIVITY (highest yields with water stress, as well as a strong anti-stress effect in all thesis) ROOTS DEVELOPMENT (more abundant and resistant roots thanks to the increased...
