INFLUENCE OF TECHNOLOGY ELEMENTS ON THE PHOTOSYNTHETIC PRODUCTIVITY OF SOYBEAN CROPS

Abstract

The use of mineral fertilizer and seed inoculation is extremely important for the development of agronomy, since soybean is one of the main crops that is widely grown in many countries, including Ukraine. Inoculation of soybean seeds promotes the formation of nitrogen-fixing nodes on the roots of plants, which increases their ability to absorb nitrogen from the atmosphere. This not only reduces the need for nitrogen fertilizers, but also improves the general condition of plants, which can positively affect the yield. In general, to achieve high and stable soybean yields, it is important to take into account all these factors and optimize their interaction The purpose of the article is to summarize the results of the features of the influence of technology elements on the photosynthetic potential of soybean varieties in the conditions of the Left Bank Forest-Steppe of Ukraine.To identify key strategies for optimizing soybean cultivation technologies, a review of the existing literature on the impact of technology elements, nutrient management, andphotosynthetic productivity improvement was conducted.In addition, field experiments and observations were conducted to assess the effectiveness of modern soybean varieties, seed inoculants, and controlled doses of mineral fertilizers in increasing photosynthetic potential.Studying the dynamics of soybean aboveground mass growth under the influence of technological cultivation measures allows us to determine ways to manage this process in order to maximize the potential of crop productivity.Phenological observations and biometric measurements of soybeans have shown a significant impact of mineral nutrition and the use of inoculants on the growth and development of soybean plant varieties. These indicators were best for the mineral nutrition system on the background of N30P45K45+ N15 top dressing and seed inoculation with the preparation BioMag Soya. The use of the inoculant BioMag Soya in combination with the microfertilizer Orakul was also effective in obtaining a larger leaf surface area in the Samorodok variety.
