Methods and results of spring barley plants treatment with growth biostimulants

Abstract

In the conditions of the Central Black Soil Region of Russia, spring barley plants experimental treatment with Polishans and Energoshans growth biostimulants, which had not previously been tested in the Central Black Soil Region of Russia concerning this crop, was carried out. The Vakula variety spring barley seeds were used for the work. Before planting, the seeds were treated with the fungicide TERRASIL Forte. The experiment was built on the randomized repetitions’ method and is a rectangular scheme. It allows to have an options complete set in each repetition, and each of them occurs in the block (repetition) only once. Thanks to this feature, the method acquires the greatest stability and flexibility. The barley plants height assessment according to the vegetation phases, barley plants general and productive tillering, seeds weight per 1 m2, barley productivity, barley seeds laboratory germination, protein content in barley seeds was carried out. Based on observations and calculations, it can be concluded that growth biostimulants and the way they are used can have a positive effect on the spring barley seeds yield and quality. The most positive effect is achieved when using drug Polishans. The profitability level increased by 4.1% with its application. This is the reason to recommend it as a foliar dressing for growing spring barley.
