Purpose. Determine the efficiency of photosynthesis of soybean varieties ‘Ustia’, ‘Kordoba’, ‘Estafeta’ as affected by the use of microfertilizers and growth regulators. Methods. Field, laboratory. Results. The article presents the results of research to study the effectiveness of photosynthesis in the cultivation of different varieties of soybean. It was found that the treatment of plants with microfertilizer Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) + in the flowering phase (0.25 l/ha) in combination with the growth regulator Radostym ensured a leaf area (1000 m2/ha) increase of 7.2 m2/ha in variety ‘Ustia’, 7.6 in ‘Kordoba’ and 5.2 in ‘Estafeta’, compared to control. At the same time, the efficiency of using the growth regulator Biosil against the background of double treatment with the microfertilizer was at the level of the treatments with single treatments with Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) in combination with appropriate growth regulators. Conclusions. It was investigated that the leaf surface area of ‘Ustia’ variety with foliar fertilization using Yara Vita Mono Molitrak microfertilizer in the budding phase (0.25 l/ha) in combination with growth regulators Biosil and Radostym was 38.8 and 39.2 thousand m2/ha. The use of microfertilizers twice in combination with the above-mentioned growth regulators contributed to the increase of leaf area to the level of 38.9 and 39.5 thousand m2/ha, respectively. Similarly, in ‘Kordoba’ soybean variety, the best option was the use of Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) + in the flowering phase (0.25 l/ha) in combination with the growth regulator Radostym, which helped to increase the leaf area to 39.5 thousand m2/ha. Foliar fertilization with microfertilizers combined with the use of growth regulators provides the formation of maximum NPP. Thus, in ‘Ustia’ variety, it was 1.47 and 1.45 g/m2, in ‘Estafeta’ 1.82 and 1.82 g/m2 of dry matter per day.

Photosynthesis is the most important biochemical process of plant life, as a result of which they absorb the energy of solar radiation and with its help synthesize organic matter from inorganic substances. The purpose of the research is to establish the influence of the growth regulator "Vermiyodis" and seeding rates on the photosynthetic productivity of winter oilseed rape plants and the Mercedes hybrid in the conditions of the Western Forest-Steppe. The study was performed during 2017-2020 in the research field of the Precarpathian State Agricultural Research Station of the Institute of Agriculture of the Carpathian region of NAAS on sod podzolic soils. The results of researches of photosynthetic productivity of winter oil seed rape plants and Cheremos hybrid at different sowing rates and application of growth regulator "Vermiyodis" are highlighted. It was found that pre-sowing treatment of rapeseed of winter variety Cheremosh with growth regulator Vermiyodis (5 l / t) and single or double spraying during the growing season with the same drug at seeding rates of 0.6; 0.8; 1.0 million / ha of similar seeds during the entire growing season had a significant impact on the formation of the assimilation surface. The area of leaves increased depending on the phase of plant development. At the beginning of the growing season, it grew slowly, reached its maximum during the budding-flowering period and began to decrease. In the variant of pre-sowing treatment of winter rapeseed Cheremosh with growth regulator "Vermiyodis" at a dose of 5 l / ha on average over the years of research at sowing rates of 0.8 million / ha of similar seeds in the stalk phase, the increase in leaf area to control was 3.5 thousand m2 / ha, in the budding phase - 6.3 thousand m2 / ha, in the flowering phase - 9.4 thousand m2 / ha. Determination of the leaf area of rapeseed plants of the winter hybrid Mercedes showed that all methods of application of the growth regulator Vermiyodis in all phases of growth and development of plants depending on seeding rates provided an increase in the leaf surface of plants of winter rapeseed. The largest leaf surface was observed in the stalk phase of 14.1 thousand m2 / ha or 2.3 thousand m2 / ha more control, in the budding phase 22.5 thousand m2 / ha or 5.9 thousand m2 / ha more control and in the flowering phase 43.7 thousand m2 / ha or 7.0 thousand m2 / ha more control was on the option, which carried out pre-sowing treatment of seeds with growth regulator "Vermiyodis" at a dose of 5 l / t and double spraying of rapeseed plants winter hybrid Mercedes growth regulator "Vermiyodis" at 4 l / ha at sowing rates of 0.6 million / ha of similar seeds. Studies have shown that in the variants where pre-sowing treatment of seeds with Vermiyodis growth regulator (5 l / t) and double spraying of winter oilseed rape plants during the growing season was used, the photosynthetic potential in the germination-wax ripening phase was 2 million million in winter rapeseed.6 million67. days / ha, which is 0.407 million m2 days / ha more than the sowing rate 0.8 million / ha, the Mercedes hybrid - 2.612 million m2 days / ha, which is 0.364 million m2 days / ha more than the sowing rate 0.6 million / ha of similar seeds. It was found that the highest net productivity of winter oil seed rape plants was 8.68 g / m2 per day or 1.46 g / m2 per day more than the control over sowing rates of 0.8 million / ha of similar seeds and 8.58 g / m2 per day in the hybrid Mercedes, which is 1.44 g / m2 per day at the sowing rate of 0.6 million / ha of similar seeds was on the option, which carried out pre-sowing treatment of seeds (5 l / t) and double spraying with growth regulator "Vermiyodis" at a dose 4l / ha during the growing season. It was found that the largest accumulation of dry matter in winter rapeseed crops Cheremosh in the budding phase is 2.98 t / ha or 0.38 t / ha more control, in the flowering phase 4.67 t / ha or 0.77 t / ha more control, in the phase of wax ripeness 8.22 t / ha or 1.36 t / ha more control, was on the option, which carried out pre-sowing treatment of seeds with growth regulator "Vermiyodis" (5 l / t) and carried out double spraying of rapeseed plants winter during the growing season growth regulator "Vermiyodis" - 4l / ha from sowing rate of 0.8 million / ha.

As a result of the conducted in 2016–2018 studies on the study of the features of photosynthetic activity of the Ratnik hybrid sunflower found that the indicators of the leaf area of one plant and one hectare changed under the influence of the use of mineral fertilizers and growth regulators and were large according to the classical system of basic tillage. The largest indices of the leaf surface area of one plant in all systems of basic tillage were noted with the introduction of full fertilizer N60P60K60. The use of growth regulators in all combinations resulted in an increase in leaf area per plant and per hectare. Large indices of net productivity of photosynthesis were noted in crops according to the classical system of basic tillage, which were, depending on the scheme of drug use: on the control (without fertilizers) – 5,95–6,16 g/m2 × day, in variants with the introduction of N40 – 6,31–6,56 g/m2 × day, in variants with the introduction of N40P60 – 6,25–6,47 g/m2 × day in the variants with the introduction of N60P60K60 – 6,29–6,42 g/m2 × day. The application of mineral fertilizers in various doses contributed to an increase in the net productivity of photosynthesis: according to the classical system by 0,31–0,44, according to the moldboard-free system by 0,02–0,24, at the minimum 0,01–0,08 g/m2 × day. The most favorable conditions for the formation of productivity by sunflower plants have developed according to the classical system of basic tillage with a yield depending on the dose of fertilizers and the option of using growth regulators 2,62–3,46 t/ha. The highest yields of the Ratnik hybrid sunflower – 3.46 and 3.45 t/ha, were obtained when growing according to the classical system of basic tillage, applying mineral fertilizers in a dose of N60P60K60 for pre-sowing cultivation of the second and fifth options for using growth regulators: 2. Rost-concentrate + Chelatin oilseeds (6–8 pairs of real leaves) 5.1 processing: Chelatin phosphorus-potassium + Chelatin мultimix + Chelatin mono boron (3–4 pairs of real leaves), 2 processing: Chelatin mono boron (6–8 pairs of real leaves). The formation of the crop was largely influenced by the system of basic tillage (r = -0.66) and the use of mineral fertilizers (r = 0.61) and the weak use of drugs (r = 0.17). It should be noted the close relationship between yield and leaf surface area (r = 0.78), CPF (r = 0.78), dry matter weight per plant (r = 0.99) and seed weight (r = 0.97 ). Key words: sunflower, system of basic tillage, mineral fertilizer, growth regulator, leaf area, net productivity of photosynthesis, yield.

The article analyzes the research on the formation of the leaf surface area of spring wheat of Darya variety in different cultivation technologies on the chernozem soil of Kursk Region. The aim of the research was to study the peculiarities of the formation of the leaf surface of spring wheat depending on the cultivation technology and to identify the conjugate relationships of indicators under the conditions of chernozem soils of Kursk Region. The results of the conducted studies indicate that intensive cultivation technology contributes to the activation of the assimilation apparatus of leaves during the entire growing season of the crop. A high direct correlation between the leaf surface area in the Z 13 and Z 55 phases and the application of mineral fertilizers was established (r = 0.73; 0.80, respectively). At Z 25 the leaf surface area has a direct noticeable relationship with primary tillage (r = 0.51) and a moderate one with the application of mineral fertilizers (r = 0.36). The use of sugar beet tops as organic fertilizer had a positive effect on the leaf area of one plant at Z 25 and Z 55, as evidenced by a noticeable correlation (r = 0.52; 0.52, respectively). It was found that the area of the flag leaf, as well as its length and width, increased with a decrease in the density of standing plants per square meter of cropped area. The flag leaf area and width decreased depending on the height of the plants, while the length increased. The development of the flag leaf area directly affected the accumulation of dry weight of plants (r = 0.53), the formation of the total assimilation surface of plants (r = 0.72), as well as a high direct relationship with the length of the ear (r = 0.75), which in turn is closely directly correlated with the weight of grain from one ear (r = 0.70). Thus, the evidence of the direct influence of the area of the flag leaf on the formation of the crop yield is presented.

Work on going through the adaptation stage of rooted micro-stalks comes down to searching for new growth regulators and studying the influence of external conditions, which include, among other things, light effects. The data of 2018-2019 on the effect of growth regulators Siliplant, EcoFus and experimental LED phytoradiators on the adaptation of rooted micro-stalks of garden strawberries (Fragaria x ananassa duch) in vivo are presented. The object of research is rooted micro-stalks of garden strawberries of the Korona variety. It was revealed that, at the adaptation stage of rooted micro-stalks of strawberries, the most effective was the treatment of plants by spraying with Siliplant at a concentration of 1.0 ml/l and the combined treatment with Siliplant and EcoFus at concentrations of 0.5 ml/l: regardless of lighting, the survival rate averaged 99.4 - 99.7%, the leaf surface area increased significantly from 291.85 mm2 to 334.4 mm2. The number of normally developed leaves of strawberry microplants increased significantly after treatment with all preparations from 3.5 to 6.0, 5.8 and 6.5 pcs/plant, and a significant increase in the height of strawberry rosettes was facilitated by treatment with Siliplant and Siliplant together with EcoFus. Regardless of growth regulators, the most effective was the experimental LED phyto-irradiator with a changing spectrum, which contributed to an increase in leaf surface area, height of rosettes and the number of normally developed leaves in strawberry microplants. When illuminated with a flashing phytoradiator, these indicators are lower than in the control version, but not significantly. By the end of the rooting stage, all microplants of garden strawberries corresponded to GOST R 54051-2010.

Wheat is the main and most important food crop in most countries of the world. It is cultivated in more than 80 countries. The purpose of the work was to study the effect of the growth stimulator Agrostimulin on the sowing traits of wheat seeds. The growth regulator Agrostimulin promotes accelerated division of plant cells, the development of a more powerful root system, an increase in the leaf surface area and chlorophyll content, reduces the phytotoxic effect of pesticides, has an antimutagenic effect, improves the quality of grown products, increases productivity, plant resistance to diseases, stress factors, resistance to adverse environmental factors (hypothermia, overheating, lack or excess of light and moisture). Its use makes it possible to reduce the rates of application of pesticides when using the drug 3–5 times during the vegetation period. The use of the growth stimulator Agrostimulin in the cultivation of spring wheat Omskaya 36 has been reflected in the article. Studies on the sowing traits of spring wheat seeds, phenological observations have been carried out. The yield of wheat Omskaya 36 variety with the use of the growth regulator Agrostimulin was 20 c/ha, which was by 2,1 c/ha or 11,7 % higher compared to the previous year. It has been revealed that the length of the vegetation period in wheat treated with the growth regulator Agrostimulin was 89 days, which was by 7 days less compared to the control. Thus, it has been experimentally proved that the treatment of spring wheat seeds Omskaya 36 with the growth regulator Agrostimulin shortens the growing season and increases its yield.

There has been conducted laboratory assessment of drought resistance of winter soft wheat samples on an osmatic solution (sucrose 16 atm.). The maximum values of this indicator ranged from 70.0% (“Lidiya”) to 79.3% (“Asket”). According to the results of vegetation trials, it was established that in conditions of insufficient moisture supply (aridity of 30% PV) during the flowering phase, the total leaf area of winter wheat varieties and lines varied from 45.2 cm2 (“Volny Don”) to 63.4 cm2 (“Kazachka”), and in the phase of milky ripeness of grain, the total leaf area ranged from 3.5 cm2 (“260/09”) to 17.7 cm2 (“Polina”). The varieties “Krasa Dona”, “Kapitan”, “Lidiya”, “Asket” showed the best ratio of the upper leaves area to the lower ones under arid conditions (in favor of the upper ones in the flowering phase). In the phase of milky ripeness, the presence of lower green leaves was identified in the varieties “Kapitan”, “Krasa Dona”, “Izyumnka”. The amount of accumulated pigments (chlorophyll) in the leaves remains the highest during the flowering period and the milky ripeness of the grain in the varieties “Kapitan” (3.1 and 2.6 m/100g of dry matter), “Kazachka” (2.9 and 2.4 mg/100g of dry matter), “Krasa Dona” (2.8 and 2.4 mg/100g of dry matter), “Asket” (2.7 and 2.3 mg/100g of dry matter), “Lidiya” (2.6 and 2.4 mg/100g of dry matter), “Izyumnka” (2.5 and 2.1 mg/100g of dry matter).

The intense vegetative growth is one of the problems faced by soybean producers, causing the lodging, making difficult and damaging the harvest and, even, the efficiency of the application of agricultural defenses. The use of growth regulators is an important tool in the management of growth, in addition, it can favor the transport of photoassimilates for grain filling. Therefore, the objective was to evaluate the best dose and time of trinexapac-ethyl application in the development and yield of soybean varieties. The experiment was conducted in the Selvíria County, Brazil (20°20′53″ S, 51°24′02″ W). The experimental design was used in randomized blocks with treatments arranged in a factorial scheme 5 x 3 (doses x times), with four replications. The varieties used were the BRS Valiosa RR and the BMX Potência RR, the doses of the growth regulator were 0; 50; 100; 200 and 400 g ha-1 of trinexapac-ethyl (Moddus®) and the application times were at the phenological stages V7, V10 and R2. The varieties BRS Valiosa and BMX Potência, respectively, were obtained at the phenological stage V10, with application of 200 g ha-1 of trinexapac-ethyl, greater dry matter accumulation of leaves and pods. Nevertheless, the same did not act on the foliar area of the BRS Valiosa RR variety in the same way that it did not induce changes in the production components of the BMX Potência RR variety. Regardless of the application period (V7, V10 and R2) and the dose (up to 400 g ha-1), the application of trinexapac-ethyl was not a management capable of influencing the agronomic characteristics and the lodging of the plants in both varieties.

The objective of this study was to evaluate growth regulators with purpose of reducing the size of heliconia ‘Red Opal’ potted plants. The experiment was carried out in randomized block design with five treatments (trinexapac-ethyl and paclobutrazol at rates of 37.5 and 75.0 mg of active ingredient per pot and control without growth regulator) and five replicates. The treatments were applied 40 days after planting the rhizomes in pots filled with soil. Thirty and 150 days after the growth regulator application, plant height, number of leaves and shoots, petioles length and leaf area were evaluated. One year after planting the rhizomes in pots the number of inflorescence and leaves (leaves, sheathing leaf bases and inflorescences) and rhizomes (rhizomes and roots) dry mass were determined. Trinexapac-ethyl had no differences compared to the control in any of the variables evaluated. Paclobutrazol proved effective in reducing plant height, leaf area and petiole length and increase in number of leaves and shoots but the effect was temporary. Also, it did not affect the inflorescences production and leaves and rhizomes dry mass. Paclobutrazol is efficient to promote height reduction and to increase the number of shoots in heliconia ‘Red Opal’ potted plants without affect the inflorescence formation but its effects is temporary.
