Different Types

Currently, sunflower is the main oil crop in the Tambov region. The most important task of modern agricultural production is the use of technologies that increase the yield and quality of field crops. Data on seed and oil yield of sunflower are very important when choosing different types of mineral fertilizers. In this regard, the purpose of our research was to study the effect of various doses, methods and terms of application of macro- and microfertilizers on yield, crop quality and oil yield of sunflower in a link of the 6-year crop rotation: fallow – winter wheat – corn (for grain) – barley – sunflower – spring wheat. The research was conducted at the Tambov Research Institute of Agriculture – a branch of the I.V. Michurin Federal Research Center, which is located in the Tambov region. On typical black soil, application of both traditional mineral fertilizers (N16P16K16) for plowing, and liquid mineral fertilizers (Megamix) during pre-sowing treatment and for plants treatment during vegetative period contributes to obtaining an additional seed and oil yields. For 2014–2020, the highest seed and oil yields were obtained in variant (5) with N30P30K30 for plowing + seed treatment with Megamix (2.0 l/t) and amounted to 2.84 t/ha and 1324 kg/ha, respectively. The fat content varied depending on the variant of the experiment. The maximum indicator of 53.6% was in the variant with the application of N30P30K30. But due to the lower seed yield, the oil yield amounted to 1.21 t/ha. All variants for seed and oil yields were superior to the control one (without fertilizers).

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.

The Impact

In the last decade, Ural and Siberian breeders have created a series of valuable and strong varieties of spring soft wheat, which have mainly successfully passed the State Variety Testing and are included in the Register of breeding achievements in 10 regions. These include the Irene variety, which is sown not only in Western Siberia, but also in Eastern Siberia and other regions of the country. It is well adapted to the conditions of the Tyumen region. The variety has been grown here for 13 years, but the variety technology has not yet been fully developed. It is cultivated according to generally accepted technology. Taking into account the current situation with the variety, we are conducting research on the development of elements of varietal technology. The article analyzes the results of the impact of mineral nutrition levels on the yield and quality of grain of spring soft wheat variety Irene in KRiMM Uporvo district of Tyumen region. Over the years of research (2016–2018), it was established that the leached black soil in the control version without mineral fertilizers yielded 2.57 t/ha of early maturing Irene variety. The variety reacts positively to the application of mineral fertilizers up to the yield level of 5 t/ha. At the same time, the yield is combined with the quality of grain. Profitability of application of mineral fertilizers for the yield of 4 and 5 tons per hectare was 130.7 and 139.5 %, respectively. In the control version it was 61.3 %. Irene variety is well adapted to the conditions of the Tyumen region, it is necessary to continue the study of other elements of the variety.

The article presents the studies carried out in 2017 and 2018 in the central zone of the Krasnodar Territory on the basis of the Agrotechnological Department of the FSBSI «National Center for Grain named after P.P. Lukyanenko». The purpose of the research was to study the dose and frequency of application of mineral fertilizers with a complex of NanoSilicon microelements, stimulating growth and development of corn and, ultimately, its yield and quality of the obtained products. Two year studies revealed the effectiveness of the positive effect of the studied drug on grain corn in all studied options. It was noted that at low or high doses of its application, a number of indicators that determine the structure of the crop and, ultimately, yield, decreased. It was found that foliar treatments increased the growing season of corn for a day. The introduction of the preparation promoted the formation of taller plants, the height of which varied from 201,3 to 212,4 cm, while in the control it was 184 cm (milk ripeness phase). In the same phase the plants had a large biological weight, which in the control was 1010,1 g/plant, and when the preparation was applied, it was 90,2–275,5 g/plant higher. Ultimately, mineral fertilization with the NanoSilicon microelement in all studied dosages had a positive effect on the corn yield, the maximum value, which was obtained when it was applied at doses of 40/75/75 (seed treatment with NanoSilicon with a rate of 40 g/ha + application by seedlings at a dose of 75 g/ha + in the phase of 7–8 leaves 75 g/ha) and 40/100/100 (seed treatment – 40 g/ha + seedlings – 100 g/ha + in the phase of 7–8 leaves – 100 g/ha), which amounted to 59,9 and 59,8 c/ha, respectively.

The purpose of research: to improve the technology of growing flax in the Western region of Ukraine on the basis of the introduction of systems for minimizing tillage, which will increase the yield of trusts and seeds. Research methods: field, laboratory, visual and comparative calculation method. Research results: Field experiments included the study of three tillage systems (traditional, canning and mulching) and determining their impact on growth and development and yields of trusts and flax seeds. The traditional tillage system included the following operations: plowing with a reversible plow to a depth of 27 cm, cultivation with simultaneous harrowing and pre-sowing tillage. The conservation system is based on deep shelfless loosening of the soil and provided for chiseling to a depth of 40 cm, disking to a depth of 15 cm, cultivation with simultaneous harrowing, pre-sowing tillage. During the implementation of the mulching system, disking to a depth of 15 cm, cultivation with simultaneous harrowing and pre-sowing tillage with a combined unit was carried out. Tillage implements and machines were used to perform tillage operations: disc harrow BDVP-3,6, reversible plow PON-5/4, chisel PCh-3, cultivator KPSP-4, pre-sowing tillage unit LK-4. The SZ-3,6 ASTPA grain seeder was used for sowing long flax of the Kamenyar variety. Simultaneously with the sowing of flax seeds, local application of mineral fertilizers (nitroammophoska 2 c/ha) was carried out. The application of conservation tillage allows to obtain the yield of flax trust at the level of 3,5 t/ha, which is 0,4 t/ha (12.9 %) more than from the area of traditional tillage and 0,7 t/ha (25 %) in comparison with mulching. In the area with canning treatment, the seed yield was the highest and amounted to 0,64 t/ha. The difference between this option and traditional and mulching tillage reaches 0,06 t/ha (10,3 %) and 0.10 t/ha (18.5 %), respectively. Conclusions. Preservation tillage, which is based on shelf-free tillage to a depth of 40 cm and disking to a depth of 15 cm has a positive effect on plant growth and development, yield and quality of flax.

The aim of the work is to study the effectiveness of the use of trace elements on potato varieties of different ripeness groups in the northern forest-steppe Ob in the Novosibirsk region. Experimental data were obtained on leached black soil of Novosibirsk region in 2017–2019. The generally accepted technology of potato cultivation was used for the experiments. Since autumn, fertilizers at a dose of P90K90 were applied as a general background for potatoes. Nitrogen fertilizers (60 kg / ha) were applied in the spring for pre-sowing cultivation. Foliar dressing with microelements (Cu, B, Zn) was used at the beginning of the budding phase of potato plants: copper – 20, boron – 45, zinc – 50 g of active ingredient per 1 ha with a working fluid consumption of 300 l/ha. Trace elements increased the growth and development rates of potato varieties of three groups of ripeness. In varieties Liubava (early), Svitanok Kievsky (mid-early), Tuleevsky (mid-season), the use of trace elements contributed to an increase in the development indicators of the photosynthetic apparatus (maximum and average leaf area and plant productivity) by an average of 21%, especially against the background of boron and zinc. Foliar dressing of potatoes increased the yield parameters by an average of 24 % relative to the control (water). The increase in the marketability of tubers reached 12 %. A greater effect was achieved against the background of boron use: a significant increase in yield, dry matter, starch, vitamin C. In variants with microelements, the susceptibility of potatoes by rhizoctonysis decreased.

The article considers the effect of increasing doses and various combinations of mineral fertilizers applied to the cover crop on the yield and quality of a mixture of perennial grasses of two - years use, as well as the effect of fertilizers on the agrochemical parameters of sod-podzolic light loamy soil. The objects of the study were Stodolich meadow clover and Leningradskaya 204 meadow timothy grass. The studies were carried out in two crop rotations - with standard and reduced single doses of mineral fertilizers. The research results showed that in the years (VIII rotation) when the unit dose of fertilizers was increased to N20P20K25, the yield of perennial grasses was higher compared to the harvest in the VII rotation. The most appropriate dose in the VII rotation on perennial grasses of the 1st year was N30P30K45, on grasses of the 2nd year - doses of N30P30K45 and N40P40K60. In the VIII rotation, the highest yield of perennial grasses of the 1st year of use was obtained at a dose of N160P160K200 (8.4 t / ha), of grasses of the 2nd year of use at doses of N80P80K100 and N100P100K125 (6.5 t / ha). Positive effect of increasing doses of mineral fertilizers on the content of soil organic matter has been noted. On the contrary, the soil acidity increased from 4.7 to 4.3 units with an increase of mineral doses. Higher doses of fertilizers increased the content of mobile forms of phosphorus and potassium in the soil.

Для обеспечения населения РФ качественной, полезной и экологически безопасной овощной продукцией в требуемом количестве необходимо изучение потенциальной продуктивности новых сортов и гибридов овощных культур, применение современных элементов технологии и продуктов в области агротехнологий выращивания. Хороший вкус, высокое содержание ценных для человека витаминов, микроэлементов и органических кислот вывело сладкий перец в ранг наиболее популярных овощных культур. В мире выведено и культивируется огромное количество сортов сладкого перца. В нашей стране наиболее распространенным сортотипом является перец сладкий (Capsicum annuum), или болгарский. На обыкновенных черноземах Бирючекутской селекционной опытной станции (Новочеркасский район Ростовской области), имеющих слабощелочную реакцию среды, мощный гумусовый горизонт, среднюю обеспеченность подвижным фосфором и высокую обменным калием, в 2017–2018 годах была исследована потенциальная продуктивность перца сладкого гибрида Темп при высоком уровне обеспеченности растений влагой и питательными элементами. Оценено комплексное действие основного внесения расчетных доз минеральных удобрений, капельного орошения, трехкратной подкормки водорастворимыми удобрениями «Мастер» и органоминеральным наноудобрением «Арксойл» на урожайность и качество перца сладкого. Выяснено, что основное удобрение и подкормки влияют, в первую очередь, на число плодов на одном растении, увеличивая их в 2–3,3 раза при незначительном повышении массы плода. Установлено, что без применения минеральных удобрений при капельном поливе было получено 25–27 т/га плодов. Использование рекомендованной дозы удобрений N120P120K120 увеличило урожайность перца до 50,5 т/га, а комплексное применение основного удобрения с 3-кратной корневой подкормкой водорастворимым удобрением «Мастер» позволило получить урожайность перца до 64,8 т/га. Наиболее высокая продуктивность растений была получена при комплексном использовании расчетной дозы на урожайность 90 т/га в сочетании с корневой подкормкой – 86,8 т/га при хорошем качестве плодов перца. To provide the population of the Russian Federation with high-quality, healthy and environmentally friendly vegetable products in the required amount, it is necessary to study the potential productivity of new varieties and hybrids of vegetable crops, use modern elements of technology and products in the field of agricultural technologies. Good taste, high content of vitamins, microelements and organic acids valuable for humans have made sweet peppers one of the most popular vegetable crops. A huge number of varieties of sweet peppers have been bred and cultivated in the world. In our country, the most common cultivar type is bell pepper (Capsicum annuum) or Bulgarian. On ordinary chernozems of the Biryuchekutskaya selection experimental station (Novocherkassk district of the Rostov region), which have a weakly alkaline reaction of the environment, a powerful humus horizon, an average supply of mobile phosphorus and high exchangeable potassium, in 2017-2018, the potential productivity of sweet pepper the level of supply of plants with moisture and nutrients. The complex effect of the main application of the calculated doses of mineral fertilizers, drip irrigation, 3-fold top dressing with water-soluble fertilizers Master and organomineral nanofertilizers Arxoil on the yield and quality of bell peppers was evaluated. It was found that the main fertilization and feeding affect, first of all, the number of fruits per 1 plant, increasing them by 2-3.3 times with a slight increase in the weight of the fruit. It was found that without the use of mineral fertilizers with drip irrigation, 25-27 t/ha of fruits were obtained. The use of the recommended dose of fertilizers N120P120K120increased the yield of pepper to 50.5 t/ha, and the complex application of the main fertilizer with 3-fold root feeding with the water-soluble fertilizer Master allowed to obtain the yield of pepper up to 64.8 t/ha. The highest plant productivity was obtained with the integrated use of a calculated dose for a yield of 90 t / ha in combination with root feeding - 86.8 t/ha with good quality pepper fruits.
