Вплив мінеральних добрив та передпосівної обробки насіння біопрепаратами на продуктивність ячменю ярого

Abstract

The aim of the work was to establish the effect of mineral fertilizers and seed treatment with a biopreparation on the productivity of spring barley. The data on the results of the research of spring barley of the Avatar variety for seed treatment with the biopreparation Azotophyt-r on different backgrounds of mineral nutrition in the conditions of the Educational and Practical Center of the Mykolaiv National University from 2022 to 2023 are given. It was established that the level of harvest depended and changed depending on the treatment of seeds with a biological preparation and the level of mineral nutrition. Over the years of research, biologics and fertilizer doses affected plant height, above-ground biomass, performance elements, and yield of spring barley. The conducted studies confirmed the expediency of pre-sowing treatment of seeds with biopreparation Azotophyt-r to optimize nutrition of spring barley plants with the aim of forming a high yield.
