Sunflower is the main oilseed crop in Russia, at the same time it is widely used in the feed production. The purpose of the research was to improve the technology of sunflower cultivation in the zone of Southern chernozems in the Volgograd region by conducting a comprehensive presowing seed treatment in an electric field with subsequent seed treatment with a growth regulator in order to increase the yield and quality of oilseeds studied sunflower hybrids. According to the chosen experimental plan, three types of experiments have been carried out. During the first experiment, seeds of sunflower hybrids NK Neoma, LG 5550, EC Petunia have been treated in the alternate current electric field, in the second experiment the seeds have been treated with a growth regulator (the drug “Zerebra Agro”), in the third experiment the seeds have been subjected to a complex effect of electrophysical and biological factors. The level of profitability on sunflower hybrids NK Neoma, LG 5550 and EC Petunia in the control (without treatment) varied in the range of 147–200 %. Processing of sunflower seeds with the drug “Zerebra Agro” contributed to the increase in the level of profitability. On the sunflower hybrid of NK Neoma the profitability level was 178 %, on the sunflower hybrid LG 5550 it was 232 % and on the sunflower hybrid EC Petunia it was 171 %. When processing seeds in the alternate current electric field, the level of profitability was higher than when processing with the drug “Zerebra Agro”. On the sunflower hybrid of NK Neoma, the profitability level was 190 %, on the sunflower hybrid LG 5550 it was 252 % and on the sunflower hybrid EC Petunia it was 184 %. When using complex pre-sowing treatment, the maximum profitability value was achieved for sunflower hybrids NK Neoma, LG 5550 and EC Petunia 230 %, 271 and 201 %, respectively.

The results of studies of scientifically grounded use of microelements in sweet pepper crops, as an important factor in increasing the yield of vegetable crops and improving the quality of products, are presented. The purpose of our research was to substantiate the influence of the use of trace elements in the technology of sweet pepper cultivation on the growth and development of plants, the productivity and quality of the products of this culture. The experimental part of the work was carried out in 2014-2019 in the subzone of light chestnut soils of the Volgograd region. Experiments on the study of trace elements were carried out by pre-sowing seed treatment and foliar feeding of plants. Chemically pure compounds of manganese sulfate, zinc sulfate, copper sulfate, ammonium molybdate, boric acid were used as microelements. The use of trace elements in the dry-steppe zone of the Lower Volga region is an important agricultural technique that helps to accelerate growth, development, increase productivity and improve the quality of pepper fruits. It is recommended to carry out pre-sowing treatment of seeds with solutions of boric acid (0.29 g / 1 l of water), copper sulfate (0.20 g / 1 l of water) and manganese sulfate (0.16 g / 1 l of water) (the ratio of the weight of seeds to the solution 1: 2) as a way to increase seed vitality, speed up yield and improve seedling quality. In order to increase the yield and improve the quality during the budding period of peppers, it is necessary to carry out foliar dressing, first of all, with solutions of boric acid (0.29 g / 1 l of water), ammonium molybdenum (0.10 g / 1 l of water), water consumption 1 l / 10 m2. Due to its high efficiency, simplicity and availability, pre-sowing seed treatment and foliar feeding of plants with microelements will find wide application in vegetable growing.

The study was conducted to evaluate the effect of 0.05% KCl on yield and quality of two peanut varieties L12 and L18 grown in Thanh Hoa province. The experiment was arranged in a completely randomized design with two factors (varieties and chemicals). After careful selection, L12 and L18 seeds were divided into two parts. Part 1 was treated with distilled water as control and part 2 was treated with 0.05% KCl. The results showed that pre-sowing seed treatment with 0.05% KCl increased the yield components and yield of both L12 and L18 when compared to the control, in which the yield of L18 in both treatments reached 37.37 quintals/ha and 39.54 quintals/ha and was higher than that of the L12 variety at 35.77 quintals/ha and 36.40 quintals/ha. Pre-sowing seed treatment with 0.05% KCl also increased the quality of peanuts such as starch content, reducing sugar, lipid, saponification value, protein, B vitamins, total amino acids and content of some mineral elements in peanuts such as N, K, Ca, Mg. Briefly, the results of this study indicated that pre-sowing seed with KCl increased the yield and quality of peanuts.

In this study, we conducted an experiment to evaluate the effect of pre-sowing seed treatment with 0.05% KCl to the yield and quality of two peanut cultivars L14 and L23 grown in Bac Ninh province, Vietnam. After careful selection, the seeds of L14 and L23 were divided into two parts. Part 1 (control) was treated with distilled water and Part 2 (experiment) was treated with 0.05% KCl. The field experiment was arranged in a Split-plot design with four replications. The results show that pre-sowing seed treatment with 0.05% KCl increased the yield components (weight of 100 pods, weight of 100 seeds, mass ratio of unshelled peanuts, number of pods per plant) and yield of both L14 and L23 when compared to the control, in which the yield of L14 is higher than that of L23. Pre-sowing seed treatment with 0.05% KCl also increased the quality of peanuts such as starch content, reducing sugar, lipid, saponification value, protein, B vitamins, total amino acids and content of some mineral elements in peanuts such as N, K, Ca, Mg. The results of this study demonstrate the importance of pre-sowing seed treatment for peanuts.

AbstractPresented paper investigates the application of a line voltage changer to an installation for pre-sowing seed treatment by pulsed electric field (PEF) in order to increase the sowing quality of seeds and to suppress pathogenic microflora. The installation comprises an AC voltage regulator, a high voltage source, a voltage inverter, a working chamber for seed treatment, a control unit, and current and voltage sensors. The proposed installation differs from the existing apparatuses as it automatically provides the transformation of the pulsed electric field parameters by constant monitoring of power processes in a layer of treated seeds and feedback sending to the control unit. Seed treatment efficiency depends on the dose being determined by the parameters of electric field, namely, intensity in the seed layer, pulse duration, pulse repetition frequency, and seed treatment time. The parameters of rational treatment were determined, and the minimum treatment dose was calculated on the basis of results from the laboratory tests on the effect of pulsed electric field on sowing qualities of winter wheat seeds. It was experimentally confirmed that the proposed installation provides automatic transformation of electric field parameters depending on the changes taking place in the seed layer on the example of seeds with different moisture content maintaining the necessary treatment dose, ensuring the stability and repeatability of results.

Complex dressers with growth stimulated components should be used to protect lupin seedlings against a number of diseases. The most efficient way to use growth regulators is their use with seed dressers as protect-stimulated compositions. High effectiveness of protect-and-stimulated mixture of the dresser Vitaros (tyram 198 g/l + carboxin 198 g/l) 2.0 l/t and the growth regulator Artaphyt (polydiallyldimethylammonia chlorid 100 g/l) 0.4 l/t for seeds’ disinfection against anthracnose and other diseases has shown. Its effectiveness against anthracnose made 95%. This mixture is effective against risoctonia and fusaria too. Use of this tank mixture for pre-sowing seed treatment of white and narrow-leafed lupin allows significantly decrease harmfulness of anthracnose and the main other diseases and increase productivity of this high protein crop.

The article presents the results of the experiment on the efficiency of different rates of herbicide Prima Forte 195 (0.5; 0.6 and 0.7 l/ha) under different application methods of plant growth regulator of a natural origin Wuxal BIO Vita (1.0 l/ha, 1.0 l/t) (spraying of vegetative plants, pre-sowing seed treatment) on weed infestation of emmer wheat. The objects of the research were emmer wheat plants (Triticum dicoccum (Schrank) Schuebl.) of the cultivar Holikovska (originator – the Plant Production Institute named after V.Ya. Yuryev, Ukraine), herbicide Prima Forte 195, с.е. (Syngenta) (active substances: florasulam 5 g/l, aminopyralid 10 g/1, 2- ethylhexyl alcohol 2.4-D 180 g/l), and plant growth regulator Wuxal BIO Vita (Unifer) (active substance – extract from seaweed Ascophyllum nodosum, nitrogen (N) – 52 g/l, manganese (Mn) – 38 g/l, sulphur (S) – 29 g/l, iron (Fe) – 6.4 g/l, zinc (Zn) – 6.4 g/l). Experiments were performed in the conditions of the crop rotation of the Department of Biology on the experimental field of Uman National University of Horticulture during 2017–2018 according to the scheme: without the use of preparations (control I), without the use of preparations + manual weeding during the growing season (control II), Prima Forte 195 at the rates of 0.5; 0.6 and 0.7 l / ha applied separately and together with Wuxal BIO Vita at the rate of 1.0 l/ha, applied separately and at the background of pre-sowing seed treatment with Wuxal BIO Vita 1.0 l/t. It was found that the herbicide Prima Forte 195 had the highest efficiency when it was applied at the rates of 0.5; 0.6 and 0.7 l/ha in combination with the plant growth regulator (PGR) Wuxal BIO Vita at the rate of 1.0 l/ha at the background of pre-sowing seed treatment with the same PGR at the rate of 1.0 l/t. Thus, the technical effectiveness against dicotyledonous weeds was on average within 86-88 % depending on the rate of the herbicide and the method of using PGR. Therefore, there is every reason to state that the herbicide Prima Forte 195 (0.5-0.7 l/ha) is effective in destroying the vast majority of dicotyledonous weeds in emmer wheat
