Nutritional conditions of plants during the growing season is one of the main factors aimed at realizing the genetic potential of sunflower hybrids for growing them in any soil and climatic conditions. Currently, it is important to study the genetic potential of domestic hybrids under different growing conditions in order to identify their competitiveness, which provides an increase in quality and yield of the crop. The use in the production of a significant range of complex microfertilizers on the background of the main fertilizer helps to increase the efficiency of plant use of nutrients of mineral fertilizers and soil, is one of the ways to increase crop yields and quality of agricultural products. Despite the relevance of sunflower as the main oil crop, the technology of its cultivation is not a perfect study, in addition, previous studies often contain conflicting indicators. An important place among the agronomic techniques aimed at increasing crop productivity belongs to the provision of optimal plant nutrition conditions during the growing season. The purpose of the research was to establish the influence of culture conditions and selection of high-yielding hybrids (NK Diamantis, SI Kupava, NK Neoma) for specific soil and climatic conditions through the formation of their productivity. The purpose of the research was to establish the influence of culture conditions and selection of high-yielding hybrids (NK Diamantis, SI Kupava, NK Neoma) for specific soil and climatic conditions through the formation of their productivity. The research was conducted during 2018–2019 on typical low-humus chernozems. The research program provided for the establishment of a three-factor field experiment, which studied hybrids (factor A) fertilizer options (factor B) and foliar fertilization of crops (factor B) in phase 4 and 8 sunflower leaves with Ecoline Bor, Nertus Bor, Bast Bor. The studied sunflower hybrids are NK Diamantis, SI Kupava, NK Neoma. The results of the research revealed significant changes in the diameter of the sunflower inflorescence under the influence of different nutritional conditions created by fertilizer options. The influence of hybrid characteristics also determined this indicator. Plants of the hybrid NK Diamantis formed baskets, the diameters of which varied from 17.6 to 21.2 cm, SI Kupava - from 18.8 to 22.1 cm, NK Neoma – from 17.2 to 21.6 cm. The maximum value was obtained on variant with the introduction of N36P56K108S28 + N23 + Ecoline Boron (phase 4 and 8 leaves) in plants of the hybrid SI Kupava, which corresponded to 22.1 cm. The weight of 1 000 achenes belonging to genetically determined traits of culture, in plants of the hybrid NK Diamantis, depending on the fertilizer variant varied from 59.3 to 62.3 g, SI Kupava from 69.8 to 74.0 g, NK Neoma from 68.8 to 72.6 g. The maximum value was provided by the variant with the use of N36P56K108S28 + N23 + Ecoline Boron (phase 4 and 8 leaves). Studies have shown that the most productive was the hybrid SI Kupava with the maximum yield on the variant with the use of N36P56K108S28 + N23 + Ecoline Boron (in phase 4 and 8 leaves of 1 l / ha) – 3.46 t per ha.

“…Today, it is necessary to study indepth the potential of hybrids and varieties for growing them in different conditions to determine their competitiveness and popularisation, which will increase the quality and yield of the crop. (Eremenko et al, 2019;Eremenko et al, 2018, Ieremenko & Kalitka, 2016. That is why today much attention is paid to the study of the influence of nutritional conditions on the formation of productivity of hybrids of both foreign and domestic breeding, in specific soil and climatic conditions of Ukraine Domaratskiy et al, 2018).…”

Plant nutrition throughout the vegetation period is one of the main factors aimed at realising the genetic potential of sunflower hybrids when cultivated in all soil and climatic conditions. Currently, it is important to study the genetic potential of domestic hybrids under different growing conditions to identify their competitiveness, thus improving crop quality and yields. The use of a wide range of complex microfertilisers in production along with the main fertiliser helps to increase the efficiency of plant nutrient utilisation of mineral fertilisers and soil and is one of the ways to improve crop yields and agricultural product quality. While sunflower is considered to be a key oilseed crop, its cultivation technology is not fully researched, and previous studies often contain contradictory data. An important part of the agrotechnical measures aimed at increasing crop productivity is to ensure optimal plant nutrition during the vegetation period. The purpose of the study was to determine the influence of crop nutrition conditions and to select high-yielding hybrids (NK Diamantis, SI Kupava, NK Neoma) for specific soil and climatic conditions through the formation of their productivity. The study was conducted in 2018-2019 on typical low-humus chernozems. The research program included a three-factor field experiment in which hybrids (factor A), fertiliser options (factor B), and foliar feeding of crops (factor C) were studied in the phase of 4 and 8 leaves of sunflower with Ecoline Boron, Nertus Boron, and Bast Boron. The sunflower hybrids studied were NK Diamantis, SI Kupava, and NK Neoma. The research results revealed significant changes in the diameter of the sunflower inflorescence under the influence of different nutritional conditions created by fertiliser variants. The influence of hybrid features also determined this indicator. Plants of the hybrid NK Diamantis formed heads with diameters ranging from 17.6 to 21.2 cm, SI Kupava - from 18.8 to 22.1 cm, NK Neoma – from 17.2 to 21.6 cm. The maximum index was achieved in the variant with the introduction of N36R56K108S28 + N23 + Ecoline Boron (phase 4 and 8 leaves) in plants of hybrid SI Kupava, and it amounted to 22.1 cm. The weight of 1,000 achenes, which is one of the genetically determined traits of the crop, in plants of the hybrid NK Diamantis, depending on the fertiliser variant, varied from 59.3 to 62.3 g, SI Kupava from 69.8 to 74.0 g, NK Neoma from 68.8 to 72.6 g. The maximum result was provided by the variant with the use of N36R56K108S28 +N23 + Ecoline Boron (phase 4 and 8 leaves). Studies have shown that the most productive hybrid was Si Kupava with the maximum yield in the variant with the use of N36R56K108S28 +N23 + Ecoline Boron (in the phase of 4 and 8 leaves of 1 l/ha) – 3.46 t / ha

Nanotechnology is seen as one of the key technologies in the twenty-first century, which promises to improve traditional agricultural practices and offer sustainable development by improving management and conservation tactics by reducing agricultural resources costs. The creation and implementation of new environmentally friendly and technological nano preparation designed to increase the efficiency of plant nutrient use from mineral fertilizers and soil - is one of the ways to increase crop yields and the quality of agricultural products. The aim of the research was to determine the effect of pre-sowing seed treatment and fertilizing of sowings by nano preparation Avatar (micro fertilizer of carboxylates of natural acids), Iodis-concentrate (immunomodulator – a stimulator of growth processes), and Super Micro Plus (nanochelate fertilizer), and leaf apparatus formation of soybean Khorol variety. Field research was conducted in 2016–2020 in a stationary experiment at the NULES of Ukraine «Agronomic Research Station» in 10-field crop rotation and also in laboratory «Demonstration collection field of crops» of the Plant Science Department. As a result of the conducted researches, was established that the use of nano preparation Avatar, Iodis-concentrate, and Super Micro Plus for seed treatment and fertilizing intensified leaf surface formation and symbiotic apparatus activity of soybean plants. The obtained results confirm that the application of the complex of nano fertilizers Jodis-concentrate, Avatar, and nano-chelate fertilizer Super Micro Plus in the soybean fertilization helped to increase the yield, which indicates their unconditional effectiveness. The highest efficiency of nano fertilizers was shown by inoculation and seed treatment by Avatar with co-fertilizing Avatar +nano-chelate fertilizer Super Micro Plus, providing formation of 52.4 thousand m2/ha of leaf surface area of soybean variety Khorol, 69.7 pcs/plant tubers on the root system, 785 mg/plant of their weight and yield at the level of 2.79 t/ha.
