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.

Sowing Seed

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.

The article presents the results of vegetation-field studies (for 2018-2020) to study the effect of trace elements on the yield and quality of greens and root crops of parsley on heavy loamy chernozems on loess-like loams. A soil mixture was poured into the vessel at the rate of 10 kg of heavy loamy chernozem. Microelements were introduced into the soil in an amount: boron – 1.0 mg; zinc – 2.5 mg; copper – 0.5 mg; manganese – 5.0 mg; molybdenum – 1.0 mg; cobalt – 1.0 mg; iodine – 2.0 mg of active ingredient per kilogram of soil. In the prepared soil, 100 parsley seeds were sown in vessels at the beginning of May. Trace elements were aplicated in the form of an aqueous solution of salts 20 days before chemical analyzes. Molybdenum in the form of ammonium molybdenum (0.05 % solution), manganese – in the form of manganese sulfate (0.6 %, solution) and boron – in the form of boric acid (0.15 % solution). The experiments were carried out in triplicate. Collecting greens was carried out when the plants reached a height of 20–25 cm, leaving petioles 2 cm high from the head of the root crop. The results of the research found that microelements: boron, copper, manganese, molybdenum and cobalt on chernozem on average over two years contributed to an increase in seed germination by 1.2–1.3 %, and the introduction of iodine into the soil slightly reduced seed germination. Parsley shoots appeared together, which was also influenced by the water–air properties of the soil. At the same time, the plants were well leafy and had a darker green color of the leaves, increased the productivity of greens and parsley root crops. In the variant where organic fertilizers were applied to the soil under the predecessor, the microelements increased the yield. This is due to the fact that organic fertilizers were introduced under the previous crop, when decomposed in the soil, they provide the plants with microelements. The increased yield of parsley root crops was obtained from the introduction of molybdenum and a double dose of copper. An increased yield of root crops compared to the control (without feeding) was obtained, respectively: cobalt – 151 g, double dose of copper – 135 g, copper – 108 g and zinc – 106 g. Thus, the use of trace elements for parsley in order to obtain high yield and quality marketable products are best used on poor soils of these elements.

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 2014–2019, we studied impact of various doses, methods and dates of applying of macro- and microfertilizers on seed and oil yields, oil content of sunflower variety Spartak bred in the Tambov Research Institute of Agriculture. The research was conducted in the Tambov region on typical black soils in 6-field crop rotation. We studied action of a liquid mineral fertilizer Megamix applied for beforesowing treatment of seeds and for foliar fertilizing of sunflower plants of the variety Spartak under application of N30P30K30 and N60P60K60. The scheme of a trial included variants with seeds treatment with the liquid mineral fertilizer Megamix and foliar fertilizing of sunflower plants in various phases of vegetative period, both separately and in complex with mineral fertilizers. For the first rotation (2014–2019), the highest seed and oil yields were obtained in variant five: N30P30K30 + seed treatment with Megamix (2.0 l per t), – 2.78 and 1.42 t per ha, respectively. The most effective method of microfertilizers application appeared to be before-sowing seed treatment. Variant five (N30P30K30 + seed treatment with Megamix (2.0 l per t) increased oil yield relative to control by 0.21 t per ha, and relative to variant two (only N30P30K30) – by 0.09 t per ha. The rest variants in the trial slightly exceeded control (variant one) both in seed and oil yields. We analyzed a role of traditional mineral fertilizers and liquid mineral fertilizer Megamix at cultivation of sunflower variety Spartak on typical black soil in the conditions of the Tambov region.

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.

Specificneed in manganese is a characteristic feature of all plants. At present time, participation of this element in functioning in a number of processes and structures in the plant organism is proved. Indispensabilityof manganese as a component of plant metabolism is evidenced by death of plants aged 2–4 weeks at absolute exclusion of manganese nutrient medium, and symptoms of disorders at all levels of metabolism due to lack of this element. As opposed to symptoms of deficiency which are specific for every element, the signs of excess are more or less the same. In conditions of gradual increase of the concentration of ions as factors of influence, gradual manifestation of plant organism depression is observed: growth inhibition, root dying and leaf chlorosis, etc. Foliar feeding of grain crops including winter wheat with manganese is very important because they have a great need for such elements as manganese and copper. Efficiencyof the types of foliar feeding is connected with the mechanisms of penetration of manganese into the plant cells. Unlike other metals, manganese can be mobilized by sprouts from seed integument: metal absorption from wheat seeds lasts till the seventh day. That’s why, the aim of our work was to investigate the influence of pre-sowing processing of winter wheat seeds with solutions of different concentrations of manganese sulfate for detection of the optimal concentration and studying of phytotoxic influence of the excess manganese action. Vegetation tests were carried out in the laboratory conditions for performing the studies. Winter wheat seeds were steeped into solutions of manganese sulfate in such concentrations as 0.001%, 0.01%, 0.1%, 0.5% and 1%. After that they were couched in multi-component environment (sod-podzol soil). As a control variant, an experiment without treatment was used. The influence of different concentrations on the growth processes such as seed germination, length of the sprout, weight of the plants and their root system was estimated. It was determined that the optimal concentration of manganese sulfate for the pre-sowing processing was equal to 0.001–0.01%. The critical one, at which the phytotoxic action is manifested in growth depression and decrease of sprout biomass, is the use of 0.5–1.0% solution of manganese sulfate for the pre-sowing seed treatment.

Spring Rape

During three vegetation periods (2015-2017), the effect of presowing seed treatment with insecticide and the sowing time on seed productivity and quality of spring rape of Accord variety was studied. Pre-sowing seed treatment was carried out 2 ... 3 days before the planting by Tabu insecticide (active substance - imidacloprid), VSK. Rape was sown at different times: early spring (perhaps early - after 5 days from it), medium spring - after 10-15 days possible early, late spring — after 20-25 days from possibly early. The experiments were laid on the sod-medium-podzolic medium loamy soil, the arable layer of moderate cultivation. The early spring period provided a longer rapeseed growing season (an average of 112 days over three years) and a relatively high seed yield of –235 g/m2. The yield advantage at the early spring sowing period is due to the greater 161 pcs per ton of plant standing before harvesting and plant productivity of 1.48 g. productive plants (164 pieces/m2). When sowing rape in medium spring and late spring, preseeding application of insecticide did not affect the yield. Sowing rape in the early and medium spring periods contributed to obtaining seeds with a higher fat content of 45%. The gross yield of fat was the highest 106 g/m2 when sowing rape in the early spring.
