Abstract

Vegetal biostimulants are organic products (natural or synthesized) that exert upon
plant growth an action similar to the phytohormones’ one, when they are applied in
small amounts, in certain stages of plant development. Biostimulants change
organisms or organs’ development, nutrition or resistance, under various stress
conditions, by inducing changes into the vital processes leading to the improvement
of crop quality and quantity, to a better and more operative mechanical harvesting
and to an improvement in the agricultural products’ preservation. The application of
biologically-active products in the smooth brome crop determined growth of the dry
matter yield of up to 1.11 t/ha depending on the product used, and the foliar surface
index increased in the variants with application of biologically-active products with
up to 1.16 m2
SA/m2
land, compared to the control variant.
