Abstract

The article is devoted to the study of the influence of a complex of amino acids of plant origin with microelements on the yield and quality of the Lobo apple tree in 2019-2020. In our studies, we studied the effect of a complex of amino acids of plant origin with microelements in three doses of 0.5, 1.0 and 1.5 l/ha on the main factors of plant development to obtain a high-quality yield. We have found that during the growing seasons 2019–2020. When assessing the effect of two-time foliar feeding of apple trees of the Lobo variety with amino acids of plant origin + microelements, a positive effect of the fertilizer was found, most manifested at a fertilizer consumption of 1.5 l/ha and a working solution of 800 l/ha. Thus, the use of an agrochemical contributed to the development of generative productivity of plants: an increase in yield in 2019 by 13.9%, by 14.5% in 2020, the average weight of one fruit - by 12.1% in 2019, by 16.4% in 2020, fruit set - in 2019 by 0.4%, in 2020 by 0.6%, as well as in improving the biochemical parameters of the fruit. The vitamin C content in 2019 in this variant was 11.8%, in 2020 – 10.4%.
