Fertilizer System

In the conditions of the Komi Republic, the effectiveness of various doses of organic and mineral fertilizers, as well as their combined use in short-term feed crop rotation, was studied in a field stationary experiment on sod-podzolic soil. As a result of scientific research (more than 40 years), it was found that the organo-mineral fertilizer system was the most effective. As a result of long-term research, it was found that the most significant yields of forage crops (on average for 3 rotations) were obtained using 80 t/ha of TNK and NPK: annual grasses – 4.4, perennial grasses – 6.2 and potatoes – 7.1 t/ha of high-quality dry matter. The dry matter content in potato tubers in the variants with NPK was 18.0–18.8%, on an organic background – 18.4–18.9, and with the complex application of fertilizers – 17.1–17.7, in the control – 19.6%. The amount of starch in potatoes slightly differed in the variants of the experiment and was equal to 12.6–13.1%. The nitrate content did not exceed the MPC (250 mg/kg of raw mass). The amount of dry matter of annual and perennial grasses changed slightly and amounted to 19.0–19.8 and 25.0–26.8%, respectively. It was found that fertilizers contributed to the increase in crude protein in annual and perennial grasses to 13.1–15.0 (in the control – 11.2%) and 8.8–10.6% (in the control – 8.1%).

SUMMARYPoultry manure and mineral fertilizers at two rates of application (medium and high) and in different combinations, together with a non-fertilized control, were tested at the Experimental Station of the Agricultural University of Padova, Italy (45° 21′ N, 11° 58′ E) in 1985–89.Compared to the control, all the fertilization treatments increased the incidence of larger-sized bulbs of onion and tubers of potato, improved the fruit colour of processing tomato and the raw protein content of spinach, but reduced the acidity and acids: soluble solids ratio of tomato and the dry matter content of spinach leaves.In addition, the application of 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as mineral fertilizer or as poultry manure gave the best scores of processing suitability of potato, both for sticks and chips. All the fertilization formulae, except for 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as poultry manure alone, showed significant decreases in the extractable sucrose ratio in sugarbeet, compared with the control. In processing tomato, the best scores of suitability for paste transformation were obtained with mixed fertilization (1/3 poultry manure and 2/3 mineral fertilizers) applying 210 kg/ha of N, 210 kg/ha of P2O5 and 150 kg/ha of K2O and the plots receiving only mineral fertilizers produced fruits with less favourable values of pH and electrical conductivity compared to the poultry manured ones.

The purpose of the work is to study the effectiveness of using horny hoofed crumbs from the waste of the meat processing industry as an organic fertilizer, in comparison with mineral nitrogen fertilizers and zeolite-containing trepel in the Chuvash Republic. The direct effect was determined on potatoes and fodder beets, the aftereffect was determined on spring barley. The soil of the experimental plot is light gray forest with a low (2.5 ... 2.6 %) humus content. The application of horn-hoof crumbs to potatoes and fodder beets at a rate of 430 kg/ha, equivalent to N60, together with phosphorus-potassium mineral fertilizers (P60K60), in terms of influence on crop yields, was not inferior to the effect of a complete mineral fertilizer at a rate of N60P60K60. In the variants with the introduction of horn-hoofed crumbs and phosphorus-potassium fertilizers, both independently and with the addition of zeolite-containing trepel at a rate of 2 t/ha, compared with the use of complete mineral fertilization, on average for 2012–2016. an increase in the biological activity of the soil was noted by 7.1 ... 11.0 %; in potato plantings, the leaf surface area increased by 7.0 ... 15.1 thousand m2/ha, the dry matter content in tubers - by 1.4 ... 2.5 %, their marketability - by 0.4 ... 0.7 %, the nitrate content decreased by 1.14 ... 1.45 %. In the crops of fodder beets, the leaf surface area of plants increased by 3.3 ... 5.0 thousand m2/ha, the dry matter content - by 0.8 ... 2.8 %, the concentration of nitrates - decreased by 43.9 ... 40.3 %. The coefficient of energy efficiency of the combined use of horn-hoofed crumb and trepel for row crops was at the level of 1.0. The aftereffect from their introduction was noted the next year when growing barley, the coefficient of bioenergy efficiency was 2.0 ... 2.2

Grass Sward

The longevity and producing capacity of perennial grasses swards was studied on mineral soils at the LUA Research Institute of Agriculture in long-term experiment during 1974-2010. There were applied lime and mineral fertilizers with different NPK doses (0-400 kg ha-1) protractedly many years. In such way there formed soils with various content of P, K, organic matter content and pHKCl level as well. Research results showed that liming of soils and using of mineral fertilizer changed not only productivity of grass mixtures but also botanical composition. Mineral fertilizer N200P100K300 provided the highest yield of dry matter – 7.32 - 12.0 t ha-1 and optimal botanical composition of a sward during many years. On unlimed soils (pHKCL less then 4.0 in 1997) dry matter yields of grass sward was substantially lower and there was observed disappearance of seeded valuable grasses out of the sward and increase of herbs and non-seeded grasses –Festuca rubra L., Agrostis tenuis Sibth., Taraxacum officinale Wigg. and others. Liming of soils increased dry matter yield in treatments with high doses of N (300-400) fertilizer.

The Impact

В условиях Республики Коми в полевом стационарном опыте на дерново-подзолистой легкосуглинистой почве изучена эффективность различных доз органических и минеральных удобрений, а также совместного их применения. Исследования проводили в 1978–2019 годах на опытных полях Института агробиотехнологий ФИЦ Коми НЦ УрО РАН. Целью проводимых исследований было изучение влияния комплексного применения удобрений на продуктивность и качество кормовых культур в шестипольном севообороте. Кормовой севооборот имел следующее чередование культур: картофель, викоовсяная смесь с подсевом многолетних трав, многолетние травы 1 г.п., многолетние травы 2 г.п., викоовсяная смесь, картофель. В результате научных исследований (более 40 лет) установлено, что наиболее эффективной была органоминеральная система удобрений, особенно при внесении 80 т/га торфонавозного компоста (ТНК) и минеральных удобрений. Многолетние исследования показали, что наиболее значительные урожаи кормовых культур (в среднем за три ротации) получены при использовании 80 т/га ТНК и NPK: однолетних трав — 4,4 т/га; многолетних трав — 6,2 и картофеля — 7,1 т/га сухого вещества высокого качества. Содержание сухого вещества в клубнях картофеля в вариантах с NPK составило 18,0–18,8%, на органическом фоне — 18,4–18,9 и при комплексном применении удобрений — 17,1–17,7; в контроле — 19,6%. Количество крахмала в картофеле незначительно различалось по вариантам опыта и равнялось 12,6–13,1%. Содержание нитратов не превышало ПДК (250 мг/кг сырой массы). Количество сухого вещества в однолетних и многолетних травах изменялось незначительно и составляло 19,0–19,8 и 25,0–26,8% соответственно. Установлено, что удобрения способствовали повышению содержания сырого протеина в однолетних и многолетних травах до 13,1–15,0% (в контроле — 11,2%) и 8,8–10,6 % (в контроле — 8,1%) соответственно. The impact of various rates of organic and mineral fertilizers was analyzed in the Komi Republic on sod-podzolic soil with low loam content. The research took place at the Institute of Agricultural Biotechnology in 1978–2019. The goal was to test forage crop productivity and quality under fertilization and six-field crop rotation. Crop rotation happened as follows: potatoes, vetch-oat mixture overseeded by perennial grasses, first-year perennial grasses, second-year perennial grasses, vetch-oat mixture, potatoes. For 40 years the combination of mineral and organic fertilizers was the most effective. The highest yields for three rotations were observed under the application of 80 t ha-1 of peat-manure compost and NPK: annual grasses produced 4.4 t ha-1; perennial grasses — 6.2, and potatoes — 7.1 t ha-1 of high-quality dry matter (DM). Potato tubers accumulated 18.0–18.8% of DM under NPK application, 18.4–18.9 — under organic nutrition, 17.1–17.7 — when using complex fertilization, and 19.6% — in the control. Starch content varied within 12.6–13.1% in potatoes. Nitrate content did not exceed the maximum acceptable concentration (250 mg/kg of raw mass). DM concentrations amounted to 19.0–19.8 and 25.0–26.8% in annual and perennial grasses, respectively. Fertilization increased crude protein amount in annual and perennial grasses up to 13.1–15.0% (versus 11.2% in the control) and 8.8–10.6 % (versus 8.1%), respectively.

An increasing interest has been observed of beetroot leaf as a salad component due to recent studies focusing on their nutritional value. The randomized field experiment was carried out on lowland chernozem soil with 6 varieties, 3 replications and 2 sowing dates. Sampling was performed on 23 of August 2018 at the stage of 30 and 50 days of vegetation, where leaf (30 and 50 days) and root (50 days) were collected. Total dry matter, folic acid and nitrate content were evaluated. The results of this investigation show that higher total dry matter content was measured in the root (8.47–10.30%) compared to the leaf in both developmental stages (6.47–9.20%). Nevertheless, higher folic acid content was found in the young leaves of 30 and 50 days of development (58.77–113.86 µg 100g-1). Among the examined varieties, Bonel has presented great amount of folic acid not only in the leaves (99.35–113.61 µg 100g-1), but also in the root (89.99 µg 100g-1). Finally, lower nitrate content was found in Libero (316.16 mg kg-1) at 30 days and in Akela (340.41 mg kg-1) at 50 days of development. Thereby, fresh consumption of beetroot leaves are highly recommended.

<p>Objetivou-se com o presente trabalho avaliar as características morfométricas e de rendimento da palma forrageira 'Gigante' submetida a diferentes tipos de adubação orgânica, química e organomineral e configurações de plantio<em>. </em>O experimento foi instalado em LATOSSOLO Vermelho-Amarelo distrófico, num delineamento em blocos casualizados, em esquema de parcelas subdivididas, com três repetições. As parcelas constituídas por duas configurações de plantio: 1) 24.0000 plantas ha<sup>-1</sup>, dispostas em fileira tripla, no espaçamento 3,00 x 1,00 x 0,25 m; 2) 26.666 plantas ha<sup>-1</sup>, dispostas em fileira quádrupla, no espaçamento 3,00 x 1,00 x 0,25 m; as subparcelas compostas por 12 tipos de adubação orgânica, química e organomineral. Aos 650 DAP mensuraram-se altura da planta, número, comprimento, largura e índice de área de cladódios, produção de matéria verde e seca e teor de matéria seca. As características morfométricas, o teor de matéria seca e a produção de massa verde e matéria seca foram influenciadas pelas adubações (P&lt;0,05), independentemente da configuração utilizada. Das características morfométricas apenas a largura e área do cladódio não foram influenciadas pelas adubações. A ausência de adubação ou apenas 30 Mg ha<sup>-1</sup> ano<sup>-1</sup> de esterco bovino são insuficientes para obter resultados satisfatórios com palma forrageira ‘Gigante’.</p><p><strong><em>Morphometric traits and yield of forage cactus 'Gigante' under different fertilization and planting settings</em></strong></p><p><strong>Abstract</strong><strong>: </strong>The objective of this study was to evaluate the morphometric characteristics and yield of 'Gigante' forage cactus subjected to different types of organic, chemical, and organic mineral fertilizers and planting configurations.

The plots consist of two plant configurations: 1) 24.0000 pl ha<sup>-1</sup>, arranged in triple row, spaced 3.00 x 1.00 x 0.25 m; 2) 26,666 pl ha<sup>-1</sup>, arranged in quadruple row, spaced 3.00 x 1.00 x 0.25 m. The subplots are composed of types of organic, chemical, and organic mineral fertilizers. On the 650th DAP were measured the plant height, number, length, width, cladode area index, fresh and dry matter yield and dry matter content. Morphometric characteristics, the dry matter content and the green mass and dry matter production were influenced by fertilization (P &lt;0.05), regardless the configuration. From the morphometric features, only the width and cladode area were not affected by fertilization.

Compositional Quality

Wilting grass before ensiling has become a firmly established practice, since it provides economic advantages due to the increment of the dry matter content of the forage before ensiling. Most forage crops contain less than 20 per cent of dry matter when they are cut thus reduction of the weight of crop to be transported provides advantages (Gordon et al., 1999). Also, research has shown that such practices yield improved and reduced effluent loss from the silo and higher feeding value of the silage. Wilting of grass prior to ensiling has been widely adopted as a means of reducing effluents produced and improving the fermentation quality of silage. The aim of this research was to assess the effect of differing wilting periods and silage moisture levels of silage quality and microbial growth levels.

A pot and a field experiment were conducted to evaluate the effects of different nitrogen and chloride fertilizer levels on the nitrate content of beetroot. The yield and dry matter content were also determined. Sulphate fertilization was used as a control to chloride fertilization. There was a considerable decrease in the nitrate content of beetroots during the growing season. High nitrogen fertilization caused nitrate accumulation in both experiments. Chloride had a significant decreasing effect on the nitrate accumulation towards the middle of the growing period in the pot experiment. In the field experiment, chloride also decreased nitrate accumulation towards the middle of the growing period, soon after additional application of ammonium nitrate limestone (13.8 % NH4-N; 13.7 % NO3-N). Chloride tends to decrease nitrate accumulation only at an early stage of root development when nitrate is not the only source of nitrogen in the soil. The yield was higher on high nitrogen supply, in the pot experiment also on chloride application. Nitrogen decreased the dry matter content, but chloride had this effect only in the field experiment.

Fodder oats (Avena sativa L, cv. Cooba) and Sudan grass (Sorghum sudanense cv. Greenleaf) were grown in pots in glasshouses with day/night temperatures of 27/22 and 21/16°C. Plants were harvested at the emergence of each leaf and at various stages after anthesis. Growth rates and changes in dry matter content, nitrogen, cellulose and in vitro digestibility in oats were similar under both temperature regimes, but more primary leaf and less panicle were formed at the high temperatures. Development of Sudan grass was more rapid at the high temperatures, but production of main shoot, panicle and tillers was much less and the nitrogen contents and in vitro digestibilities were consistently lower than at the low temperatures. Sudan grass produced much more dry matter than oats. Differences in composition were in general not large, though stem digestibility remained higher in Sudan grass after anthesis. Tropical species, because of their efficiency of photosynthesis and water use, warrant further study of their nutritive value as forage crops in temperate regions.

The article presents the results of a study of the effect of applying doses of mineral fertilizers (N0P0K0, N30P30K30, N60P60K60, N90P90K90) when cultivating varieties of spring barley (Vladimir, Reliable, Yaromir) on the formation of the area of leaf plates, the growth of green biomass and the accumulation of dry matter by crop plants in different years of moisture in the South of the Central non-Chernozem region. It was found that the use of mineral fertilizers in doses N60P60K60, N90P90K90 contributed to the greatest increase in the area of the assimilation apparatus and the growth of plant biomass. In the phase of entering the tube, the leaf area on the above backgrounds exceeded the control variants by an average of 49,6 and 63,3 % (Vladimir variety), 62,3 and 45,4 % (Reliable variety), and 44,6 and 53,2 % (Yaromir variety). The average growth of biomass in 2017-2019 with the use of N60P60K60, N90P90K90 increased compared to the control variants by 83,3 and 182,7 % (Vladimir variety), by 68,9 and 88,3 % (Reliable variety) and by 82,0 and 107,5 % (Yaromir variety) in the beginning of earing phase with further growth of this indicator to the phase of milk ripeness of plants. The percentage of dry matter in plants depended not only on the doses of mineral fertilizers, but also on weather conditions, namely, on the value of the Selyaninov hydrothermal moisture coefficient (SCC). With an increase in the applied rates of fertilizers, at values of GTC in the range of 0,37 – 0,44, dry matter is accumulated by plants, at values from 0,64 to 1,2, due to the provided moisture and greater water consumption by spring barley varieties, the percentage of dry matter content decreased. Yield – the final indicator of all conditions. Reliable and Yaromir varieties showed the greatest stability in obtaining a good harvest, which exceeded the values of control variants on average for 2017-2019 by 89,1 and 79,0 % on backgrounds N60P60K60 and N90P90K90 respectively. Correlations were determined for all the studied indicators.
