- Abstract
The paper presents a biostimulant (codified Bios) containing algae extract (Ascophyllum nodosum), hydrolysed proteins, as well as humic substances with effects on plant growth and mineral nutrition, thus reducing the negative effect of climate and technological stress. The application of the biostimulant indirectly stimulated the plants for the additional absorption of nutrients as well as the increase of the photosynthesis process. The foliar application of the Bios product (as a 0.5% solution) led to the increase of the yield of wheat and tomato crops compared to the unfertilized control. The production increases were 36.46% for wheat and 50.12% for tomatoes. The stimulation of the photosynthesis process for both crops tested is evidenced by the increases of the concentrations of chlorophyll a and b measured in the treated leaves as compared to the control. The same trend was found for the carotene content. The nitrogen, phosphorus and potassium content of the leaves were also determined, and there were found significant increases compared to the unfertilized control.
