RESEARCHES CONCERNING THE EFFECT OF SOME BIOLOGICALLY-ACTIVE PRODUCTS ON FORAGE BIOMASS YIELD IN SMOOTH BROME
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.
