The Utrisha biostimulator presents a new approach to the use of nitrogen applied to corn crops. A three-factorial experience with corn hybrids was located for two years (2023 and 2024) on the chernozem of Caracal. Three corn hybrids (factor A) fertilized with 3 doses of urea (factor B) were sown after their seed was treated with the Utrisha biostimulator and the Instinct stabilizer with 4 doses (factor C). The corn hybrids used were: P9944, P0260, P0450.
The tested urea doses were: 50 kg/ha, 100 kg/ha and 150 kg/ha and the biostimulator doses: untreated, Instinct 1 liter/ha + Utrisha N 250 g/ha, Instinct 1.7 liter/ha + Utrisha N 333 g/ha and Instinct 2.5 liter/ha + Utrisha N 400 g/ha. The root biomass and plant height were analyzed in terms of the influence of the studied factors and their interaction. Among the factors, only factor C had a very strong influence on the root biomass and among its graduations, the seed treatment with Instinct 1 liter/ha + Utrisha N 250 g/ha had a very significant influence, this being a lower dose than the recommended one.
