Biogeninių augimo stimuliatorių poveikis vasariniams miežiams skirtingo drėgmės režimo sąlygomis

Abstract

The experiment was carried out with spring barley "Ūla". Since the beginning of tillering period the plants were grown under stress conditions. Afterwards, spring barley, except control treatment plants, were sprayed with water, solutions of 1,0% nitrogen fertilizers, amino acids, amino acids with humic acids and ainino acids with trace elements. It was identified that under stress conditions the amounts of chlorophyll a and b in the leaves of spring barley were most efficiently increased by solutions of 1% amide nitrogen fertilizers and of amine with humic acids. Amino acids and their combinations with humic acids or with trace elements did not have essential impact on the amount of potassium in the leaves of spring barley.
