Abstract
The article reflects the results of a study on the effect of fertilizers and plant protection on the photosynthetic activity of seed crops of winter wheat when grown in South Ukrainian. One of the most important elements of the technology of growing wheat seeds is the formation of the optimal nutritional regime and the introduction of integrated plant protection. These important agrometeorological measures are able to enhance the photosynthetic activity of plants, contribute to the production of high and high-quality harvests, greatly enhance the economic and energy efficiency of domestic agriculture. The aim of the studies was to study the effect of the background of mineral nutrition and plant protection on the photosynthetic activity of seed sowings of winter wheat, depending on conditions in the south of Ukraine. The aim of the study was to determine the influence of the factors under study on the dynamics of leaf surface area formation, the photosynthetic potential, the net productivity of photosynthesis, and the absorption parameters of FAP by winter wheat crops. Field experiments were carried out according to the technique of an experimental case according to a scheme that provided for the study of the effect of mineral fertilizers with their application for basic soil cultivation and fertilizing, as well as the protection of plants from pests. It is established that the use of fertilizers significantly increases the area of the leaf surface of winter wheat. The use of plant protection from weeds, diseases and pests has a positive impact. The best conditions conducive to the formation of a large area of the leaf surface and its long-term functioning are created by applying N30-60P40 and N60 in the spring in combination with integrated plant protection from autumn. Also, the improvement in the background of mineral nutrition and plant protection promoted the growth of the photosynthetic potential of crops and the net productivity of photosynthesis. The high level of absorption of FAR by winter wheat crops - more than 75%, was with the application of fertilizers in a dose of N90-120P40 in combination with integrated protection grew.
