Background: This study of the large-flowered azalea cv. ‘Anneke’ investigated the impact of two factors, i.e., methods of fertilization and mycorrhization, on the nutritional status of plants during three years of nursery cultivation. Methods: Single mineral fertilizers, a slow-release fertilizer Hortiform pH (SRF), and fertigation in combination with mycorrhization of plants, were applied. Plant roots were inoculated with fungi from the genera Oidiodendron and Hymenoscyphus sp. The nutritional status of the large-flowered azalea in the first three years of cultivation was assessed based on macroelements. Results: The analyses revealed significantly higher content of nitrogen, phosphorus and calcium in the leaves of plants inoculated with fungal mycelium. A beneficial effect of plant mycorrhization on plant nutritional status, i.e., higher levels of nitrogen, phosphorus, potassium, calcium, and magnesium, was noted in the second and third years of azalea cultivation. Conclusions: Significant amounts of the nutrients were utilized in the middle of the growing season and almost fully utilized after the season. Hence, the necessity to supplement nutrients in each subsequent year of plant vegetation was postulated. Fertigation was shown to require further improvement of the nutrient solution.

Relevance. One of the most important elements of the technology of cultivation of strawberries for increasing productivity and improving the quality of berries is the use of fertilizers that can regulate the growth, development, yield and quality of products.Methods. During 2016-2018, the impact of pre-planting application of complex mineral fertilizers on the yield and quality of strawberries in the Udmurt Republic was studied. The analysis of meteorological conditions during the growing season of the crop according to the research results is carried out.Results. The results of the use of complex fertilizers Azofoska, Perm-yagodnoye and Fusco-yagodnoye on garden strawberries when grown in the conditions of the Udmurt Republic are presented. It was found that the use of these fertilizers in comparison with the control (Azofoska) contributes to an increase in yield and has a positive effect on the quality of berries. The aftereffect of the studied fertilizers on the second and third year of fruiting of wild strawberries is noted. According to the results of research, the highest yield of berries of the garden strawberry was obtained in 2016 in the first year of fruiting when applying Chamfer-berry (1.33 kg/m2 ). The pre-planting application of the FaskoYagodnoye fertilizer provided a reliable increase in yield at all times of berry harvesting, and on average for three years by 0.13 kg/m2 with an NSR of 0.04 kg/m2 . The content of dry matter, water-soluble sugars and vitamin C in the berries corresponded to the characteristics of the Darenka variety and to a greater extent depended on the meteorological conditions of the growing season of strawberries.

AbstractCranberry (Vaccinium macrocarpon Ait.) is a species that is becoming increasingly popular due to the health value and taste qualities of fruits. Studies on cranberry ‘Pilgrim’ were carried out in 2012-2013 in the nursery farm. Plants were grown in containers in open space. The effect of method of fertilization and application of mycorrhizal vaccine on the growth, development and nutritional status of plants during the first two years of cultivation in the nursery was evaluated. Fertilizer characterized by a controlled release of nutrients (CRF) – Osmocote 6M, agent with sustained-releasing components (SRF) – Hortiform pH, fertigation and fertilization using Hortiform pH combined with fertigation, were applied. The vaccine contained fungi of Hymenoscyphus sp. genus that are characteristic for Vaccinium genus. Significantly greater weight of plant shoots as well as nitrogen, phosphorus, potassium, calcium and magnesium contents were recorded in plants supplied with the mycorrhizal vaccine. A positive effect of slow-releasing fertilizers on plant weight and their chemical composition has been demonstrated, whereas plants fertigated developed lower mass of shoots and contained less nitrogen, phosphorus, potassium, calcium and magnesium.

Growth of Japanese black pine (Pinus thunbergi Parl.) seedlings in containers was enhanced by incorporating a slow-release fertilizer (Osmocote) and micronutrient source in the growth medium while dolomite was detrimental. Seedlings transplanted into the field showed excellent survival, regardless of propagation treatment, however, plants grown with Osmocote and micronutrients in the container medium were significantly larger after 1 growing season. Root-to-shoot ratio was not related to survival or growth. Container-grown seedlings were larger after 3 months than 2-year-old conventional bed-grown plants and continued to outgrow the bed-grown seedlings after one year in the field.

The article presents the results of research conducted during 2016-2019 on the impact of different rates of mineral fertilizers and by-products of the predecessor on the content of chemical nutrients in plants and the yield of maize hybrids in the Forest-Steppe. The aim of the research was to establish the peculiarities of nitrogen, phosphorus and potassium accumulation in maize plants in ontogenesis in relation to the yield of hybrids of early and middle-early maturity groups to optimize the mineral nutrition of the crop. The research was conducted on dark gray wooded soil using field, chemical, calculation-weight and mathematical-statistical methods. According to the stages of growth and development of BBCH, the peculiarities of the dynamics of nitrogen, phosphorus and potassium content in plants of hybrids with FAO 190 and 280 depending on the agrochemical load of growing technology are established. Varietal regularities of concentration of chemical elements in maize plants in connection with the accumulation of dry matter by crops in ontogenesis and yield were revealed. Hybrids with the corresponding genetically determined level of nitrogen, phosphorus and potassium content in plants have been identified and its influence on the realization of genotype productivity potential has been shown. The decisive role of potassium and nitrogen in the formation of the corn crop on dark gray wooded soil has been experimentally proved and confirmed on the basis of statistical and correlation analyzes. All hybrids were characterized by high tightness of correlations between yield and content in plants of nitrogen (r = 0.760–0.934) and potassium (r = 0.755–0.943) during the growing season as opposed to phosphorus, where these connections were of medium strength (r = 0.334–0.589) and only partially close (r = 0.702–0.806). According to the results of plant diagnostics of mineral nutrition of plants, the most effective growing technologies with different agrochemical loading are singled out, which ensure the yield of early and middle-early maize hybrids in agro-climatic conditions of the Forest-Steppe at 9.56–10.39 and 11.21–12.10 t/ha.

Sanderson, K. R. and Fillmore, S. A. E. 2012. Slow-release nitrogen fertilizer in carrot production on Prince Edward Island. Can. J. Plant Sci. 92: 1223–1228. The impact of nitrogen management using slow-release fertilizers has not been examined for carrot (Daucus carota L.) production in Atlantic Canada. To assess the effects of such products, we evaluated five slow-release fertilizers over a 3-yr period. Treatments consisted of sulphur coated urea (SCU) (42–0–0), isobutylidene diurea (IBDU) (31–0–0), Nutralene® (methylene urea) (40–0–0), Sirflor® (urea formaldehyde) (38–0–0), UFLEXX™ (urea, dicyandiamide, N-(n-butyl) thiophosphoric triamide) (46–0–0) compared with industry standard (ammonium nitrate) (34–0–0). All slow-release fertilizer treatments supplied N at 50 kg N ha–1 pre-plant. Slow-release fertilizer treatments were compared with the industry standard of 50 kg N ha−1 pre-plant plus 50 kg N ha–1 as a top dress. UFLEXX™ increased biological and marketable yield by 7.5 and 18.7%, respectively, compared with the industry standard. Sirflor® produced the lowest yield. GreenSeeker® NDVI reading and LECO N were correlated at the mid-season sample. GreenSeeker® technology has potential as an in-field crop health assessment tool, however, further research is required to develop GreenSeeker® algorithms appropriate for carrot production in Prince Edward Island.

The article presents the results of research to assess the impact of technological methods on the productivity of single and compatible crops of sugar sorghum with soybeans, and in particular the methods of sowing and fertilizing. The main organ of the plant that absorbs the most solar energy and has the highest intensity of photosynthesis is the leaf. The use of mineral fertilizers had a positive effect on the total leaf surface. During years of the research with the study methods of sowing and the timing for determination of total leaf surface in areas under mineral fertilizers were applied, it was greater than in areas without fertilizers. Thus, on average for 2018-2019 in the phase of ejection of panicles in areas where sugar sorghum was sown together with soybeans according to the scheme one row of sorghum + one row of soybeans under applying N120P90K120 leaf surface was 30.1 thousand m2/ha, and in areas without fertilizers - 21.0 thousand m2/ha It was found that the largest area of assimilation surface of leaves on average for two years (41.3 thousand m2 / ha) was in the phase of milk ripeness of grain under sowing two rows of sorghum + one row of soybeans and N120P90K120 consumption. For the efficient use of solar energy is important not only the size of the leaf surface area but also the duration of its active work. Photosynthetic potential is used as an indicator for characterizing of the photosynthetic work of crops during the growing season. The maximum value of the photosynthetic potential of sorghum plants on average for two years of research (2018-2019) was obtained at the end of the growing season (2.81 million m2 days/ha) in areas where it was sown together with soybeans in the method of sowing two rows of sorghum + one-row soybeans and under application of N120P90K120 doses. Keywords: Leaf surface area, photosynthetic potential, sugar sorghum, method of sowing, fertilizer.

The influence of systematic application of mineral fertilizers, on the background (BG) of the after-effect of 30 t on ha of manure, on the content of nutrients in spring wheat plants of “Myronivska Yara” regional variety and winter wheat plants of “Myronivska 61” variety, and on nutrients removal by plants, during cultivation on Meadow-Chernozemic Carbonate Soil, was studied. The results indicate a close relationship between external conditions and internal metabolic processes in winter and spring wheat plants. Thus, a balanced ratio of nitrogen, phosphorus and potassium provides a more intensive supply of these elements from the soil, what increases their content in plants. The highest content of total nitrogen, phosphorus and potassium in winter wheat plants was observed in the variant, where 1.5 rate of mineral fertilizers was applied with the background of 30 t on ha of manure, in the tillering phase and was 4.86; 2.17; 3.48 %, respectively, what is almost 2 times higher, than the control. During the growing season, the nutrients content in all variants decreased. The same pattern was observed in plants of spring wheat. The maximum nutrients content was recorded in all variants in the phase of spring tillering, and also was recorded significant reduction in their adsorption from the soil and using by plants during the growing season. The content of total nitrogen in spring wheat plants in the tillering phase fluctuated in fertilized variants in the range of 2.21-2.51 %, compared with the control – 2.10 %; phosphorus – in the range of 1.20-1.47 %, compared with the content on the control – 1.04 %; potassium – 1.88-3.08 %, in the control, respectively – 1.68 %. The results of research indicate, that long-term application of fertilizers in crop rotation affects, as a result, also on the removal of nutrients with the crop. Thus, the removal of basic nutrients by plants of winter and spring wheat was the highest in the variant “BG + N110P120K120”. Under winter wheat it was 210 kg on ha N, 122 P2O5, 157 kg on ha K2O, compared with the control variant – 86.3 N, 48.2 P2O5, 57.8 kg on ha K2O. Under the spring wheat it was 119 N, 66.4 P2O5, 85.4 kg on ha K2O, and in control variant, respectively, – 46.6 N, 26.5 P2O5, 32.8 kg on ha K2O.

The nutrient status of apple trees was assessed in two productive orchards on different soils in southern Tasmania. The concentration of nitrogen, phosphorus, potassium, calcium, and magnesium in leaf samples was determined over three growing seasons, once in the first year and at three-weekly intervals in the second and third years. Comparisons were made with overseas standards of sufficiency in the elements, and relations were sought with apple yields and tree growths. For most of the elements there was a period of relative stability in concentration towards the latter half of the growing season (late January-early February). The representative concentration of all elements, estimated during this period, declined only slightly in the successive years but remained at sufficient levels, even though growth of the trees and apple yields increased greatly. A moderately high concentration of potassium in the leaves of a number of trees appeared to be associated with a depressed yield of the apples, apparently because it lowered the concentration of magnesium in the leaves.
