The purpose of the research is the developing of methods for increasing the productivity of sunflower hybrids culti-vated on the basis of the Clearfield system, when applying fertilizers and up-to-date micro-fertilizing Agromineral mixture within the conditions of the middle Volga forest-steppe. One of main factors increasing the economic poten-tial of sunflower is the introduction on a great scale of highly productive hybrids and the improvement of its cultiva-tion technology. Fertilizers rational use and foliage spraying in order to increase the yield and improve its quality indicators is the basis for effective crop production. The Samara agricultural University experimental field was pro-vided for the research to be conducted. The scheme developed envisaged application of fertilizers at a dose of 10:26:26 NPK with a norm of 100 kg/ha of Diammophos and 60 kg/ha of Nitrabor, followed by treatment of sunflow-er hybrids during 4-6-crop stage with micro-fertilizing agromineral mixture. The results of research for 2017-2019 are presented with an assessment of sunflower hybrid photosynthetic potential, yield and oil content at different fertilizer dose applica-tion and treatment of crops by microfertilizing Agromineral mixture. On average, over three years of research, the maximum photosynthetic potential is observed in hybrids: in the control group without both fertilization and vegeta-tion treatment – 8H358KLDM (3.066 million m2/ha days), when fertilizing use – LH 5555 KL (4.008 million m2/ha days). On average, for 3 years of research, the yield of sunflower hybrid on the basis when no fertilization was used amounted to 22.5...28.7 C/ha, and with fertilization – 27.2...33.3 C/ha. With the use of microfertilizing Agromineral mixture, but no fertilizers added oil yield amounted to 13.23 C/ha. The same result was obtained on a fertilized field 15.60 C/ha.

The work presents the results of studies for 2017-2019, aimed at developing methods for increasing the productivity of sunflower hybrids cultivated according to the Clearfield system when using the microfertilizing mixture Agromineral in the forest-steppe zone of Middle Volga region. The results of the studies showed that the safety of plants at the time of harvesting is up to 91.8%; the maximum safety is achieved when processing crops by vegetation with Agromineral microfertilizing mixture at a dose of 3 l/ha. The leaf area increased until the budding phase, reaching a maximum of 99.2 thousand m2/ha, on a mid-season hybrid when processing crops with a dose of 3 l/ha, and then, due to drying of the lower leaves, it begins to decrease to the phase of the onset of flowering to 37.8 ... 57.9 thousand m2/ha. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8N477KLDM - 4.781 million m2/ha days. The use of fertilizers and micronutrient mixtures increases its value and, as a result, increases productivity by 9.09 ... 9.36 kg/ha with an absolute indicator of 27.2 ... 33.2 kg/ha.

The article presents an assessment of the productivity and quality of oilseeds of the Asteraceae family in the agro-climatic conditions of the forest-steppe of the Middle Volga region. The object of the research: safflower (Carthamus tinctorius), milk thistle (Silybum marianum), guizotia (Guizotia abyssinica). Insufficient amount of precipitation was observed during the growing season of 2019 (Selyaninov Hydrothermal Coefficient (HTC) – 0.68). In 2020, a moderate precipitation deficiency was observed during the growing season (166.9 mm); year was characterized as arid (HTC 0.78). The growing season 2018 was severely arid (HTC 0.34). The length of the safflower growing season during the monitoring years was 108–121 days, guizotia — 111–130 days, milk thistle — from 111 to 117 days. The number of developed flower heads per one safflower plant was 15.3, guizotia – 112.5, milk thistle – 7.5. The productivity of one plant varied from 9.2 to 19.2 g; the coefficient of variation (CV) was 8.1–29.3 %.1000-seed weight did not vary significantly; CV ranged from 2.5 (guizotia) to 7.3 % (milk thistle). All crops in the forest-steppe of the Middle Volga region formed a high yield of oilseeds (0.88–1.68 t/ha) with oil content up to 24.51–40.62 % and were characterized as highly drought tolerant (62.1–71.3 %). Guizotia abyssinica provided a high yield of seeds (1.54–1.68 t/ha) and a significant content of oil in them (40.62 %). The drought-tolerant coefficient (DC) was 68.5 %. Carthamus tinctorius is an amazing drought tolerant plant; DC – 71.3 %. On average, its seed yield amounted to 1.37 t/ha; oil content – 24.51 %. Content of oleic acid in Silybum marianum oil was high (29.43 %), seed oil content – up to 29.31 %, seed productivity – 0.70–0.88 t/ha. In general, these crops combine high oilseeds’ productivity and quality and are of interest for introduction in the forest-steppe of the Middle Volga region.

Castor oil (Ricinus communus L.) is an important commercial product. The climatic conditions of Ukraine determine the possibility of growing the castor as an annual crop. At the Institute of Oilseeds NAAS studied castor collection. The aim of the work was the selection of the most promising samples of castor oil, combining a large yield potential in a narrow range of vertical distribution for optimal technological parameters of mechanical harvesting with a high content of oil in seeds and ricinolic acid in oil. In the experience of 2015-2016, the manifestation of morphological features of 17 castor bean samples was studied. The height of plants, individual samples among themselves differed more than twice. Long-brush samples of ЕР118, К374, М203, К159 are distinguished on the basis of the length of the brush. The shortest brush was observed in sample K1008. The length of the productive brush in the studied samples is from 10.7 to 32.9 cm. Most castor bean samples under favorable conditions form brushes of the second and higher orders. According to this parameter, samples of Ep118 and selection No. 38 with four inflorescences of the second order are of the greatest interest. The largest brushes of the second order are similar in size to the brushes of the first order were observed in the samples: К1127, К810, К153. The adaptability of harvesting castor beads requires that the brushes of the first and second order coincide in height with each other, since the harvester can take a maximum of 60 cm. For the sum of the productive brushes of the first and second orders, the greatest potential yield will be provided by samples K159 and K1127. Among the studied collection stands out the small seed sample K159 and the large seed samples - PRL41 and K80. The average oil content in the seeds of the collection was from 52 to 61.4%. Sample38 had the highest oil content. The content of ricinolic acid in the collection was from 70.9 to 82.9%. Samples were isolated: К134, К1008, PRL41, К430 with the content of ricinoleic acid more than 80%. The results of the study of all parameters make it possible to isolate valuable technological samples. Sample K1064 with a high technological potential of productivity, with a seed oil content of 57.2%, has a not very high content of ricinoleic acid of 74.3%. Sample K1127 with an oil content of 58.6%, a mass of 1000 seeds of 265 g, a high potential of productive brushes has a wide variation in the arrangement of brushes. Sample K134 with a oil content of 57.1%, ricinoleic acid content of 80.7% has small second-order brushes and can be used as a single-cysts in a thicker seeding.

Recognizing the growing interest in the application of organic photovoltaics (OPVs) with greenhouse crop production systems, in this study we used flexible, roll-to-roll printed, semi-transparent OPV arrays as a roof shade for a greenhouse hydroponic tomato production system during a spring and summer production season in the arid southwestern U.S. The wavelength-selective OPV arrays were installed in a contiguous area on a section of the greenhouse roof, decreasing the transmittance of all solar radiation wavelengths and photosynthetically active radiation (PAR) wavelengths (400–700 nm) to the OPV-shaded area by approximately 40% and 37%, respectively. Microclimate conditions and tomato crop growth and yield parameters were measured in both the OPV-shaded (‘OPV’) and non-OPV-shaded (‘Control’) sections of the greenhouse. The OPV shade stabilized the canopy temperature during midday periods with the highest solar radiation intensities, performing the function of a conventional shading method. Although delayed fruit development and ripening in the OPV section resulted in lower total yields compared to the Control section (24.6 kg m−2 and 27.7 kg m−2, respectively), after the fourth (of 10 total) harvests, the average weekly yield, fruit number, and fruit mass were not significantly different between the treatment (OPV-shaded) and control group. Light use efficiency (LUE), defined as the ratio of total fruit yield to accumulated PAR received by the plant canopy, was nearly twice as high as the Control section, with 21.4 g of fruit per mole of PAR for plants in the OPV-covered section compared to 10.1 g in the Control section. Overall, this study demonstrated that the use of semi-transparent OPVs as a seasonal shade element for greenhouse production in a high-light region is feasible. However, a higher transmission of PAR and greater OPV device efficiency and durability could make OPV shades more economically viable, providing a desirable solution for co-located greenhouse crop production and renewable energy generation in hot and high-light intensity regions.

The paper presents studying sedative activity of the combined tincture of motherwort and St. John's wort. The combined tincture of motherwort and St. John's wort was obtained by percolation method in a ratio 1:10. Standardization of the obtained tincture was carried out with quality indicators: description, content of active ingredients and ethanol, relative density, dry residue. According to all quality indicators, the tincture obtained met the requirements of the State Pharmacopoeia of the Republic of Belarus. Specific sedative activity of the combined tincture of motherwort and St. John's wort was assessed by barbiturates hypnotic effect prolongation (sodium thiopental), by the rate of falling asleep in animals and by animals staying in lateral position in relation to the control group to which sodium thiopental was injected. In the studies carried out it was found that injection of the combined tincture of motherwort and St. John's wort at a dose of 0,1 ml / kg increases sleep by 125,63% and also accelerates the process of falling asleep by 327,75% compared with the separate injection of motherwort and St. John's wort tincture at doses of 0,1 ml/kg. It was shown that the injection of the combined tincture of motherwort and St. John's wort at a dose of 0,1 ml/kg exhibits a potentiated effect and enhances the hypnotic effect of sodium thiopental administered at a dose of 10 mg/kg.
