The Cost

A powerful factor in increasing the yield of feed mixtures is the use of mineral fertilizers. On average, over 4 years of research, the yield of green mass increases from 13.8 tons per hectare at the control (without fertilizers) to 27.4 tons per hectare (almost 2 times). However, the effectiveness of the use of mineral fertilizers depends on how the sunflower and annual herbs are placed in space. Thus, on all backgrounds of mineral nutrition, the highest yield of green mass was obtained by sowing sunflower and annual herbs in separate strips with strip widths of 180 cm: N85P38K46 - 28.2 tons per hectare; N99P44K54 - 32.9 tons per hectare; N113P51K61 - 34.2 tons per hectare. In the same conditions, both narrowing the bands to 90 cm and expanding to 360 cm reduce the yield of the object of study. Mineral fertilizers also have a great influence on the gross yield of raw fat (an increase of 2.8 times), feed units - from 2,562 to 3,904, crude protein - 1.9 times, exchange energy - 2.4 times. As a result, the payback of each ruble of the cost of mineral fertilizers provides for the production of 1.5 rubles, and the bioenergy coefficient increases to 4.4, versus 2.2 for mixed sowing of sunflower and annual herbs.

We can expect to receive from 0.81 to 0.97 tons of sunflower oil seeds per hectare in the soil-climatic conditions of the forest-steppe zone of the Middle Volga region without the introduction of mineral fertilizers. As the doses of mineral fertilizers are increased, the productivity of 1 hectare of arable land is increased 2.8 times and the gross collections of oilseeds are 2.14 tons per hectare at the non highest background of mineral nutrition, against 0.86 tons per hectare in the control variant of the experiment (without fertilizers). The optimization of seeding rates of the studied culture is of great importance in the formation of highly productive agrocenoses. In the variants of supplementary supply of plants with nutrients, especially when N98P38K124 is introduced, the seeding rate of 70 thousand pieces per hectare of virgin seeds raises the yield of sunflower by 0.51 tons per hectare (a very solid increase in yield), compared with the sowing rate of 60 thousand pieces per hectare.

The research explores the relation between productivity of binary grass mixture and mineral nutrition. The hypothesis assumes that nutrient value of the same forage depends on mineral nutrition of forage grasses. According to purpose of research, the authors specified the task which is seen to analyze the impact of mineral fertilizers on productivity and nutrition of forage mass of binary grass mixture sown under the cover. The object of the research is a binary grass mixture based on alfalfa (Medicago + sainfoin). Sowing was carried out under the barley and Sinapis cover on two mineral backgrounds: control (without fertilizers) and fertilized. Fertilizers were applied the day before sowing. Crop yield and the quality of harvested mass were assessed in the appropriate period which was the stage of Medicago budding. Two-year industrial and economic experiment highlighted necessity and efficiency of sowing Medicago binar grass mixtures under Sinapis cover with 25% lower sowing rate and apply mineral fertilizers dosed as N23P60K60 in the forest-steppe of Novosibirsk region. This application contributed to the highest output of metabolic energy in dry matter (37 GJ/ha). The authors observed a positive tendency on harvesting from 1 ha of fodder units (2.14 tons), digestible protein (0.35 tons), as well as the yield of dry (3.58 tons) and green mass (13.7 tons). In this variant the authors observed the highest output of metabolic energy in dry matter (37 GJ/ha). There was a positive tendency to harvest fodder units (2.14 tons), digestible protein (0.35 tons) pro 1 ha and get dry (3.58 tons) and green mass (13.7 tons).

The article presents the results of research conducted in different soil and climatic conditions of the Middle Volga region on the influence of regulated factors, as well as environmental factors on the production process of plants of various types of spring wheat. The amount of photosynthetically active radiation (PAR) is enough to obtain yields within 12–13 tons of dry biomass or 6–7 tons of grain. Natural precipitation is able to provide 3.82–4.36 t of spring wheat grain from 1 ha, and 4.5–6.3 t/ha by the total influence of solar energy, heat and moisture supply. Natural level of soil fertility without application of organic and mineral fertilizers allows to receive about 2 tons of spring wheat grain from 1 ha. Application of nitrogen in the form of ammoniac water (N-20.5 %) increased the yield in comparison with the use of nitrogen in the form of ammoniac saltpeter: the increase was 0.14 t per 1 ha. In the conditions of grey forest soil in the Predkamye region of the Republic of Tatarstan the optimal norm of sowing of spring wheat Triticum dicoccum Schuebl (spelt) depending on the feeding background was established. Growth of yield at sowing of 6 million seeds per hectare at all levels of nutrition in comparison with sowing rate of 4 million tons per hectare was 0.18 tons per hectare against the natural background, against the estimated background of NRC on 2.0 tons of grain – 0.19 tons and 2.5 tons of grain – 0.24 tons per hectare. The maximum yield increase was received at a combination of a mineral foodstuff with an optimum norm of sowing and has made on a settlement background 2 tons of grain from hectare – 0.20 tons, on 2.5 tons of grain – 0.34 tons from hectare. Thus, the aim of our research was to develop methods of growing high yielding quality grain of different types of wheat adapted to the conditions of forest-steppe in the Volga region.

The Impact

The article presents findings of the influence of different levels of mineral nutrition on plant growth and development, the impact of fertilizers on the botanical composition, on the productivity and forage benefits of cereal-bean agrocenoses in the forest-steppe zone of the Baikal region. The objects of research were mixed crops of oats with peas and millet with vetch, peas, and Austrian winter pea. Legumes are the main source of protein increase in feed. In the field, the most widespread, among legumes, were vetch, sowing peas, field peas (Austrian winter pea). As a result of phenological observations, it was found that the growth and development of plants depended on the biological characteristics of crops, weather conditions and directly on the mineral nutrition level. The millet reacted most effectively to the application of mineral fertilizers, starting from the exit phase into the tube. The introduction of mineral fertilizers in pre-sowing tillage contributed to an increase in the proportion of legume components in the total green mass yield and a decrease in cereals. The highest competition in agrocenoses of millet with legume components was vetch, its share in the mixture increased, compared to the unfertilized background, by 6 and 14.5%, depending on the background of fertilizers. It was found that, compared with the unfertilized background, mineral fertilizers increased the yield of green mass from 1.5 to 4.9 tons per hectare, the collection of dry matter from 0.4 to 2.0 tons per hectare and the collection of feed units from 0.3 to 1.3 tons per hectare. Digestible protein content in 1 unit increased with the introduction of nitrogen fertilizer (N45), depending on the type of components in the mixture, from 3.2 to 6.6 g, and with the introduction of complex mineral fertilizer (N45P30K30) from 2.5 to 9.6 g. All are millet-bean mixtures at all levels of mineral nutrition comply with zootechnical standards.

The article studies the reaction of new Bellarosa potato variety on the introduction of calculated doses of mineral fertilizers and the density of planting in the forest-steppe soil of the Middle Volga region. The research shows that increased nutrition appropriately raises the yield of Bellarosa potato variety. The introduction of calculated fertilizer doses aimed at obtaining 30 tons of potato per hectare has increased the yield by 8.17–10.96 t/hectare depending on the planting density. Over 4 years of research the highest yield of 31.18 t/hectare was obtained when the planting density was 66.6 thousand tubers per hectare. It’s worth noting that higher planting density increased the effectiveness of the fertilizer introduced in calculated doses for this level of yield. The increase in potato harvest, in this case, was 4.22 and 5.81 t/hectare. The following increase in planting density with further enhancement of nutrition didn’t show such high effectiveness. For example, in the case of fertilizer dose calculated for the yield of 35 t/hectare the increase of density to 60.6 and 66.6 thousand tubers per hectare (in comparison with 55.5 thousand) gave the rise of 1.62 and 2.62 t/hectare in yield. Over 4 years of research the introduction of the fertilizer dose calculated for the yield of 40 t/hectare gave an additional 1.60 and 2.90 tons of potato per hectare.

With the development of modern floral business, Callistephus chinensis (L.) Nees is among the top three of the most popular crops, yielding only chrysanthemum and calendula in commercial cultivation. This is one of the most widespread seasonal decorative annual flower crops, which is beautifully cultivated in open ground, pots and bouquet flowers. The researches presented in the article were conducted in order to determine the influence of weather conditions during the growing season of C. chinensis on the research sites of the educational scientific-production complex of the Sumy National Agrarian University (Northeast Forest-steppe of Ukraine) and the effectiveness of the application of various norms of complex mineral fertilizers, introduced at the planting of seedlings into open ground, on the processes of growth, flowering and other qualitative characteristics of the five varieties. During the growing season, the climatic conditions of the region of conducting research, variety characteristics, and also the variability of the parameters of height, number and diameter of C. chinensis inflorescences of the varieties 'Olenka', 'Leleka', 'Litnia Nich', 'Tsarivna' and 'Yabluneva' were influenced by variability mode of mineral nutrition. Weather conditions of vegetation have an impact on the number and size of inflorescences. According to research results, it has been established that there is a certain relationship between the weather conditions of the year and the number of inflorescences. So, the increase in the amount of precipitation during the growing season contributes to the development of the vegetative mass, but also negatively affects the formation of the number of inflorescences C. chinensis. For most varieties, the optimal conditions for the development of the generative sphere were the normal conditions for moisture of the year, and for the 'Litnia Nich' variety it was dry. The greatest increase in height when fertilizing compared to control was observed by the variety 'Tsarivna' (15.9 %), the smallest - by the variety 'Olenka' (2.0 %). The formation of inflorescences of greater diameter by the plants of the varieties 'Olenka', 'Litnia Nich' and 'Tsarivna' was observed in 2016, and by the 'Leleka' and 'Yabluneva' varieties in 2017. For most varieties in 2015, the diameter of inflorescences was the smallest. Studies have shown that weather conditions do not have a significant effect on the diameter of inflorescence, unlike mineral nutrition. The diameter of the inflorescences was the highest in comparison with the control by the variety 'Olenka' (18.3%), the smallest - by the variety 'Tsarivna' (1.1 %). The most valuable morphological and decorative features of C. chinensis plants of the five varieties under study were formed according to the norms of complex mineral fertilizers (nitroamofoska) 6.0 g/m2. The further increase of norm was not appropriate.

Chernozem Soils

The influence of various levels of mineral nutrition on the accumulation of plant-root residues of spring wheat and oats in the conditions of the forest-steppe zone of Western Siberia is studied. The natural agricultural background of leached chernozem was taken as a control. The research was carried out at the station of the Department of Soil Science and Agrochemistry of the State Agrarian University of the Northern Trans-Urals. In the experiment, various doses of mineral fertilizers were used, ensuring the yield of grain crops from 3.0 to 6.0 t/ha. It was found that the mass of plant-root residues of spring wheat and oats has no significant differences and depends on the level of mineral nutrition. On the natural agricultural background, the mass of plant-root residues is 3.24-3.88 t/ha. Fertilization increases the yield of grain crops to 6.0 t/ha, and also increases the amount of plant-root residues: spring wheat - 4.47; oats – 6.04 t/ha. Increasing the doses of mineral fertilizers reduces the ratio of yield to the mass of plant-root residues from 1:1.6 to 1:1.10 units. It was found that almost half of the root system of spring wheat and oats is located in a layer of 0-10 cm, while the share of roots in a layer of 30-40 cm accounts for no more than 16% of the mass.

The Cost

In modern socio-economic conditions, the production of high-quality grain remains the main task of agricultural production. The main way to solve it is to increase productivity by introducing new varieties and crops with high potential and improving the cultivation technology with minimal costs. Agrarians of the North-East of the Non-Chernozem Zone of Russia, having in their land, use poorly fertile sod-podzolic soils of varying degrees of cultivation. To increase the productivity of grain crops, they use adapted resource-saving technologies, in which the level of mineral fertilizer is determined by the magnitude of the dose of the nutrient established experimentally. The high productivity of the variety, along with the quality of the grain, is the most important indicator of the ultimate goal of every breeder. To assess the economic efficiency of the cultivation of spring triticale, studies were carried out on nine varieties: Saur, Dobroe, Zaozerye, KNIISH 9, KNIISH 11, KNIISH 22, Savva, Timur, Rovnya. The results of our studies convincingly indicate that in the conditions of the republic, even against an unfertilized background, cultivated varieties of spring triticale, provide grain yield from 2.5 to 3.8 t/ha. Some of the most important economic indicators characterizing production efficiency are such indicators as the cost of production and the degree of efficiency of grain production, expressed by the level of profitability. The main application of mineral fertilizers (N60P60K60, (P60K60) and the introduction of nitrogen fertilization in tillering at a dose of N30 increases the cost of 1 kg of grain by 5-8%, thereby reducing the profitability of production when cultivating varieties. The cultivation of varieties Rovnya, Zaur, Zaozerye, KNIISH 22, KNIISH 11, Timur was economically profitable, but less profitable than varieties KNIISH 9, Dobroe and Savva. The cost of production of a kilogram of grain was on the option without mineral nutrition from 5.1; 7.0; 5.9; 5.1; 4.8; and 6.4 rubles, respectively. On fertilized options, the cost decreased to a minimum of 4.1 rubles in the Timur variety with the main application of N60P60K60 with nitrogen fertilization N30 during tillering. The maximum increase in the cost price was shown by the varieties Timur, Zaozerye: 4.8 and 4.9 rubles against the background of the main application of N60P60K60. On average for 2020 according to the results of economic analysis, the lowest cost price and the highest level of profitability indicator are observed when cultivating varieties KNIISH 9, Dobroe and Savva at all levels of mineral nutrition.

The productivity of annual feed grass mixtures (vetch + oats, Sudan grass + white mustard, Sudan grass + oilseed radish), sown after the winter rye harvesting during the “shooting” phase (the 1st time of sowing), during the “heading” phase (the 2nd time of sowing), and during the phase of complete ripeness (the 3d time of sowing), was studied in the conditions of forest-steppe soils of the Volga Region (the Republic of Mordovia). The experiment was carried out in 2018-2020 on heavy loamy soils against the background of three doses of mineral fertilizers use (without fertilizers, N16P16K16 + N30, N16P16K16 + N60). It has been established that the duration of vegetation of feed mixtures according to the time of sowing when harvesting for green mass was: at the first the time of sowing - 63-85 days, at the second - 63-76 days, at the third - 56-62 days. The highest height of the plant was at the first time of sowing with the use of fertilizers at a dose of N16P16K16 + N60, the lowest - at the third time of sowing. The highest growth was achieved by Sudan grass (48-116 cm), the lowest - by the mixture of vetch and oats (18-67 cm). The highest yield of green mass (14.0 t/ha) was observed when cultivating Sudan grass mixed with oilseed radish on the background of N16P16K16 + N60 at the first time of sowing. For mixture of Sudan grass with white mustard, the yield was 2-7 % lower, and for vetch + oats mixture - 32-45 % lower. The same was observed according to the yield of dry matter and feed units. As to the protein content, mixtures of Sudan grass with cruciferous crops exceeded the vetch + oats mixture by 7-26 %. The fiber content in the grass mixtures was decreasing from the first time of sowing to the last. The greatest amount of fiber (28.11-28.72 %) was observed during the second time of sowing. The economic assessment showed that the cultivation of annual grass mixtures after winter rye without mineral fertilizers was the most cost-effective (29-208 %). The highest efficiency (202-208 %) was provided by the mixture of Sudan grass with oilseed radish and white mustard.
