“…Present world consumption of oils is 123.8 million tons and expected to increase to 137 million tons per year in the next decade (ISTA, 2016). Sunflower is the third largest source of vegetable oil worldwide next to soybean and groundnut both in terms of area and production (Yeremenko et al, 2017). In terms of production, the top countries are Ukraine (11.9 million tons), Russia (9.7 mt), European Union (7.72 m t), Argentina (2.7 m t), Turkey (1.1 m t), India (0.52 m t) and others (7.18 million tons) (FAOSTAT, 2017).…”

“…Yeremenko et al found that, although both hybrid and plant growth promoters affect yield of sunflower. They found influence of hybrid (85%) is much much more than the PGR (7.5%) [29]. Naik et al [30] observed the effect of 2,4-Dichlorophenoxyacetic acid and its lanthanide complexes, and indole 3 acetic acid-derived Schiff base and their lanthanide complexes on the germination and growth activity on wheat seeds, and found the best results at 10 -6 M concentration.…”

Although the development of organic products have been a decisive factor in rapid development for the last two centuries, hazardous solvents, nonbiodegradable catalysts, and long reaction times have always been a serious issue in organic synthesis. The solution to all issues highlighted above lies in the environment-friendly synthesis and green chemistry. In such synthesis, reaction time is decreased by using energy-efficient methods of heating (like microwave irradiation), high yield, biodegradability, good selectivity of solvents, good performance of catalysts, and usage of environment-friendly greener solvents like water, ethanol, acetone, etc. in an all-in-one approach [1]. Auxins, a class of naturally organic compounds, are plant growth hormones found in and required by plants in very little amounts, yet their presence is very critical. This class of compounds contain acetic acid-based Pol. AbstractPreparing novel compounds using environment-friendly protocols for plant growth has remained a major goal for plant scientists. In this research, effect of a novel plant growth promoter on sunflower (Helianthus annuus L.) was assessed hydroponically as well as in soil acclimatized plantlets at 1, 10, and 100 µM. The plants were also assessed for antioxidant enzymatic and antifungal activities. The synthesized derivative 2 produced significantly better results in terms of overall growth as compared with standards at 1 µM concentration among all compounds. Increased catalase and superoxide dismutase levels in plant seedlings treated with synthesized compounds were observed when grown in hydroponics, but these values were found to be significantly low as compared to soil-acclimatized plants. No significant zone of inhibition was found on agar plates in antifungal bioassay.

The use of microfertilisers against the background of the main fertiliser helps to increase the efficiency of using nutrients of mineral fertilisers and soil by plants, which ensures an increase in yield and an improvement in the quality indicators of the grown crop. The purpose of the study was to establish the influence of crop nutrition conditions and select highly productive hybrids (NK Diamantis, SI Kupava, NK Neoma) for specific soil and climatic conditions through the formation of their productivity. Field studies were conducted during 2018-2019 on typical low-humus chernozems of the Chernihiv region. The study programme provided for the laying of a three-factor field experiment, in which hybrids (factor A) fertiliser options (Factor B), and foliar top dressing (factor C) were examined in the phases of 4 and 8 sunflower leaves with Ecoline Boron, Nertus Boron, Bast Boron products. Sunflower hybrids under study are NK Diamantis, SI Kupava, and NK Neoma. Studies showed that the most productive was the SI Kupava hybrid with the maximum yield indicator in the option with the application of N36R56K108S28 + N23 + Ecoline Boron (in the phases of 4 and 8 leaves of 1 l/ha) – 3.46 t/ha. The fat content in sunflower seeds was determined by the morphobiological features of the hybrid and fertiliser options. The use of foliar top dressing with microelements had a positive effect on the fat content in the seeds of sunflower hybrids, which allowed obtaining the maximum indicator in the option with the application of N36R56K108S28 + N23 + Ecoline Boron (5-6 leaves) in plants of the SI Kupava hybrid – 51.1%. The maximum content of oleic acid was identified in the SI Kupava hybrid in the option with added N27R42K81S21 + N23 + Ecoline Boron (5-6 leaves) – 77.2%. Due to the use of fertilisers containing boron, the content of this polyunsaturated acid can be increased, improving the quality indicators of sunflower seed oil. The highest oil yield, according to the calculations performed, was obtained in the option with the application of N36R56K108S28+N23 + Ecoline Boron (5-6 leaves) in plants of the SI Kupava hybrid, which amounted to 1.64 tonnes per 1 hectare
