ABSTRACT Basil (Ocimum basilicum L.) is an annual plant that belongs to the Lamiaceae family. It is used as an aromatic and medicinal plant. Basil is grown in different regions with varying climates; the productivity and quality are influenced by both abiotic and biotic factors. This study was aimed to determine the impact of the application of different types of fertilizers on the yield and contents of some bioactive components in basil. The treatments consisted of three different types of fertilizers (mineral, organomineral, and organic) and control (without fertilization). The yield per plant and the essential oil content with fertilizer treatment were better than that in control. The highest fresh yield (450.9 g per plant) and oil content (0.94 mL 100 g-1) were recorded in basil cultivated using mineral fertilizers. Furthermore, the fresh yield (333.9 and 327.8 g per plant) and oil content (0.87 and 0.85 mL 100 g-1) were higher after the application of organic and organomineral fertilizers compared to that in the control treatment. There was no significant effect of fertilizer application on the total phenolics, total flavonoids, and antioxidant capacity. This study demonstrated a suitable practical application of organomineral fertilizers as a nutrient source in basil crop production in areas where the use of mineral and organic fertilizers is limited.

Aim. To determine the specifi ed parameters of the complex model of nitrogen-carbon circulation while using different types of crop rotation, kinds of organic fertilizers and ways of soil cultivation in agroecosystems of the forest-steppe zone of Ukraine. Methods. Field, laboratory, computational, mathematical and statistical. Results. Specifi c types of organic fertilizers affect the emission of СО 2 into the lowest atmospheric layer: in case of humus the typical emission interval is 25–85 t/ha, while in case of secondary products it is 70–160 t/ ha. The impact of the way of chernozem preparation on nitrogen-carbon circulation is manifested in the fact that in case of subsurface tillage the carbon balance in soil was positively increasing compared to ploughing. The interval of СО 2 emission into the lowest atmospheric layer due to the mineralization of humus and organic fertilizers with ploughing changes in a wider range compared against subsurface tillage. Conclusions. The nitrogen-carbon interactions are impaired due to the introduction of humus and removal of secondary products beyond the boundaries of the agroecosystem in the course of ploughing. The application of ground secon- dary products of crop production as organic fertilizers, wrapped up into the surface layer of chernozem during the subsurface tillage of soil, simulates the natural course of nitrogen-carbon circulation in agroecosystems of different types. Natural soil formation process is simulated due to the activation of photosynthetic activity of cultivated crops with СО 2 saturation in the lowest atmospheric layer, which provides for extensive restoration of chernozem fertility in the forest-steppe zone of Ukraine.

The impact of nutrition area on Thymus vulgaris L. accumulation of essential oils in dry raw materials (Thymiherba) was studied and described in the article. Four schemes of cultivation were chosen to be studied: 45×40 cm — 56 thousand plants/ha, 45×30 cm — 74 thousand plants/ha, 45×20 cm — 111 thousand plants/ ha, 45×10 cm — 222 thousand plants/ha. It was shown that the increase of nutrition area helped to increase the content of essential oils in dry raw materials. Dry thyme grass with the highest content of essential oil 21.3 ml/kg was obtained when variants with the largest plant nutrition area were applied (the schemes of cultivation 45×40 cm — 56 thousand plants/ha). Reduction of the nutrition area decreased the essential oil content. According to the scheme of cultivation 45×30 cm (74 thousand plants/ha) content decreased to 20.8 ml/kg, and for the minimal nutrition area 45×10 cm (222 thousand plants/ha) the content of essential oil was 18.5 ml/kg. It was confirmed that main part of the essential oil in the raw thyme is contained in leaves, flowers and small sprouts. At the same time the woody stems contain essential oil only in trace amounts. According to the cultivation scheme 45x10 cm (222 thousand plants/ha) the leaves contained 34.2 ml/kg of essential oil, when the stems only 2.1 ml/kg. When the area of plant nutrition was increased the quality of raw materials slightly improved — for the scheme of cultivation 45x30 cm (74 thousand plants/ha) leaves contained 35.9 ml/kg, stems — 2.1 ml/kg of essential oil. The content of essential oil in the leaves was the highest — 36.2 ml/kg while using the scheme with maximum researched plant nutrition area 45×40 cm (56 thousand plants / ha). The efficiency of four norms of basic mineral fertilizers application was investigated: N0P0K0, N60P60K60, N120P120K120 and N180P180K180. It was found that increasing the rate of fertilizer application increased the yield of dry raw thyme and the content of essential oil. The most effective rate of fertilizer application is N180P180K180, which provided a dry leaves yield of 2.48 t/ha with an essential oil content of 38.2 ml/ha.The results showed that with the increase of the number of plants per unit area, the share of leaves in the total mass of raw materials decreased from 52.3% to 45.1%, but due to a significant increase in plantation productivity, dry leaf yields increased. The highest productivity was recorded for the variant of cultivation schemes 45×10 cm with a planting density of 222 thousand plants/ha, where the yield of dried thyme leaves was 1.52 t/ha.

Climate change, expanding soil salinization, and the developing shortages of freshwater have negatively affected crop production around the world. Seawater and salinized lands represent potentially cultivable areas for edible salt-tolerant plants. In the present study, the effect of salinity stress on plant growth, mineral composition (macro-and micro-nutrients), and antioxidant activity in dune spinach (Tetragonia decumbens) were evaluated. The treatments consisted of three salt concentrations, 50, 100, and 200 mM, produced by adding NaCl to the nutrient solution. The control treatment had no NaCl but was sustained and irrigated by the nutrient solution. Results revealed a significant increase in total yield, branch production, and ferric reducing antioxidant power in plants irrigated with nutrient solution incorporated with 50 mM NaCl. Conversely, an increased level of salinity (200 mM) caused a decrease in chlorophyll content (SPAD), while the phenolic content, as well as nitrogen, phosphorus, and sodium, increased. The results of this study indicate that there is potential for brackish water cultivation of dune spinach for consumption, especially in provinces experiencing the adverse effect of drought and salinity, where seawater or underground saline water could be diluted and used as irrigation water in the production of this vegetable.

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.

Abstract. Land degradation has been a persistent problem in Senegal for more than a century and by now has become a serious impediment to long-term development. In this paper, we quantify the impact of land degradation on crop yields using the results of a nationwide land degradation assessment. For this, the study needs to address two issues. First, the land degradation assessment comprises qualitative expert judgements that have to be converted into more objective, quantitative terms. We propose a land degradation index and assess its plausibility. Second, observational data on soils, land use, and rainfall do not provide sufficient information to isolate the impact of land degradation. We, therefore, design a pseudo-experiment that for sites with otherwise similar circumstances compares the yield of a site with and one without land degradation. This pairing exercise is conducted under a gradual refining of the classification of circumstances, until a more or less stable response to land degradation is obtained. In this way, we hope to have controlled sufficiently for confounding variables that will bias the estimation of the impact of land degradation on crop yields. A small number of shared characteristics reveal tendencies of "severe" land degradation levels being associated with declining yields as compared to similar sites with "low" degradation levels. However, as we zoom in at more detail some exceptions come to the fore, in particular in areas without fertilizer application. Yet, our overall conclusion is that yield reduction is associated with higher levels of land degradation, irrespective of whether fertilizer is being applied or not.

Soybean is known for its high protein content, which is the reason why it is widely used as one of the main food sources for humans and animals. In order to optimize soybean growth, farmers tend to add excessive dosage of chemical fertilizer to this crop. Furthermore, a continuous chemical fertilizer application without organic fertilizer addition may cause a rapid depletion of nutrients in the soil. This study aimed to evaluate the effectiveness of organic fertilizer treatment to reduce the amount of urea as chemical fertilizer needed in soybean cultivation. A complete randomized design was conducted using 21 treatments of organic and chemical fertilizer in triplicate with a 4x3 m plot size. Analysis of variance was carried out to compare the means of measurement data and Duncan multiple range test (DMRT 5%) was applied. The treatment 2,000 kg ha-1 compost + 50 kg ha-1 urea (O2K2A1) resulted the highest dry yield in soybean and had significant differences with urea-only treatment. A mixture of chemical and organic fertilizers had no significant result over the yield compared to the use of chemical fertilizer only. Compost application of 1,000-2,000 kg ha-1 with urea 50-100 kg ha-1 (O2K2A1 and O 2K1A2) showed an increase in seed yield of 35-38 % with a profit reaching 333-340 USD ha-1 compared to standard treatment using urea 50 kg ha -1 + SP-36 50 kg ha-1 + 50 KCl kg ha-1 (O0K0A1).

Farmers use Inorganic Fertilizers (IF) to improve kenaf yield in Nigeria. However, the detrimental effects of mineral fertilizers and its high cost calls for the use of organic fertilizers that are locally available and environment friendly. Combination of Organic Fertiliser (OF) with IF may reduce the bulkiness of OF while harnessing the benefit of both for higher yields. Field trials were conducted at Ibadan and Ilora in 2013 and 2014 to investigate the effects of combined fertilizers on the growth and yield of kenaf. Organic and IF (NPK 20:10:10) fertilizers as: (i) 160 kg ha-1 (sole organic), (ii) 100 kg ha-1 (sole IFl), (iii) Organic and IF at 50:50 ratio and (iv) control (no fertilizer). The experiment was laid out in Randomized Complete block design (RCBD) and replicated three times. Results showed that plant height (220.17 cm, 216.80 cm) and stem diameter (2.27 cm, 1.16 cm). Bast fiber (2.27 t/ha, 2.27 t/ha) and seed yield (1.69 t/ha, 1.78 t/ha) in Ibadan and Ilora respectively were significantly higher in plots with combined fertilizer. Combined fertilizers had the highest fiber and seed yield above sole application and control (no fertilizer application). Hence it is recommended for kenaf cultivation in Southwest Nigeria.

SUMMARYIncreasing recognition of the extent to which nitrous oxide (N2O) contributes to climate change has resulted in greater demand to improve quantification of N2O emissions, identify emission sources and suggest mitigation options. Agriculture is by far the largest source and grasslands, occupying c. 0·22 of European agricultural land, are a major land-use within this sector. The application of mineral fertilizers to optimize pasture yields is a major source of N2O and with increasing pressure to increase agricultural productivity, options to quantify and reduce emissions whilst maintaining sufficient grassland for a given intensity of production are required. Identification of the source and extent of emissions will help to improve reporting in national inventories, with the most common approach using the IPCC emission factor (EF) default, where 0·01 of added nitrogen fertilizer is assumed to be emitted directly as N2O. The current experiment aimed to establish the suitability of applying this EF to fertilized Scottish grasslands and to identify variation in the EF depending on the application rate of ammonium nitrate (AN). Mitigation options to reduce N2O emissions were also investigated, including the use of urea fertilizer in place of AN, addition of a nitrification inhibitor dicyandiamide (DCD) and application of AN in smaller, more frequent doses. Nitrous oxide emissions were measured from a cut grassland in south-west Scotland from March 2011 to March 2012. Grass yield was also measured to establish the impact of mitigation options on grass production, along with soil and environmental variables to improve understanding of the controls on N2O emissions. A monotonic increase in annual cumulative N2O emissions was observed with increasing AN application rate. Emission factors ranging from 1·06–1·34% were measured for AN application rates between 80 and 320 kg N/ha, with a mean of 1·19%. A lack of any significant difference between these EFs indicates that use of a uniform EF is suitable over these application rates. The mean EF of 1·19% exceeds the IPCC default 1%, suggesting that use of the default value may underestimate emissions of AN-fertilizer-induced N2O loss from Scottish grasslands. The increase in emissions beyond an application rate of 320 kg N/ha produced an EF of 1·74%, significantly different to that from lower application rates and much greater than the 1% default. An EF of 0·89% for urea fertilizer and 0·59% for urea with DCD suggests that N2O quantification using the IPCC default EF will overestimate emissions for grasslands where these fertilizers are applied. Large rainfall shortly after fertilizer application appears to be the main trigger for N2O emissions, thus applicability of the 1% EF could vary and depend on the weather conditions at the time of fertilizer application.

Intensification of horticulture in Russia involves planting of new high-density orchards with drip irrigation and fertigation as well as intensification of the exploitation of traditional orchards. This approach involves an increase in mineral fertilizer application imposing the risk of soil fertility loss. For several reasons, the use of traditional organic fertilizers like manure in orchards is currently marginal. Although bacteria-based biofertilizers cannot substitute mineral fertilizers completely, they can significantly reduce the need for mineral fertilizer application. The effect of microbial biofertilizers of the brands “Azotovit” (Azotobacter chroococcum), “Phosphatovit” (Bacillus mucilaginosus), as well as a mixture of bacteria and the fungus, “Organic” (Azotobacter chroococcum, Bacillus subtilis, Bacillus megaterium, Trichoderma harzian) was studied in two field experiments. In the experiment #1, the preparations “Azotovit” and “Phosphatovit” were delivered through a drip irrigation system in various combinations with mineral fertilizers. In experiment #2, the preparation “Organic” was also applied to the soil with irrigation water, also in combination with the mineral fertilizer. When solely applied, none of the studied preparations changed significantly the soil nutrient content and yield as compared with the variant fertilized by the mineral fertilizer at the maximum studied application rate. The combination of the microbial biofertilizer and mineral fertilizers applied at a low rate ensured the yield commensurate to that obtained under high-rate application of the mineral fertilizer.
