Abstract

Within two years, based on theoretical data and research by other scientists in the arid conditions of the Volgograd region, an experiment was laid on the basis of the Federal Scientific Center of Agroecology of the Russian Academy of Sciences in the Kamyshinsky district in the village of Gosselek station on the influence of modern micro fertilizers on spring barley. Our goal was to obtain data on practical application, as well as to analyze and identify the dependence of various yield coefficients and preparations on climatic conditions characteristic of the region. The object was spring barley (Hordeum vulgare) and modern biological products. When conducting research in 2020-21, climatic conditions and adaptive properties of spring barley in the arid zone were taken into account. Observations were carried out according to the methodology of Dospekhov and the state variety testing. After harvesting, a structural analysis of the components of plant productivity was carried out (the number of productive stems per plant, the number of productive spikelets in the ear, the number of grains in the main ear, the number of grains in the spikelet, the number of grains from the plant and the mass of grain from the main ear, the mass of grain from the plant and the mass of 1000 grains). Processing and analysis of mathematical data were carried out in the Excel program. The significance of the difference between the analyzed indicators (NSR05) was determined with a reliable probability of 95%, the arithmetic mean (M) and standard deviation were calculated (±SD). The coefficient of paired correlation (r) between the indicators of the crop structure was calculated with a reliable probability of 95%. The significance level P < 0.05 was taken as reliable. Data analysis showed that the best indicators of the structure of the spring barley crop were obtained on variant B3. On the basis of the data obtained, regression models were constructed that revealed the relationship between yield factors. Based on the processed data for 2020-21, it can be concluded that there is a direct relationship between the yield of spring barley and the signs. The yield of spring barley can be influenced not only by the introduction of various drugs that stimulate the development of plants, but also by the soil and climatic conditions of the region.
