The purpose of research was to determine the optimal method of applying mineral fertilizers with drip irrigation in strawberry plantations and the level of available forms of nitrogen, phosphorus, and potassium in sod-podzolic mediumloam soil. The studies were carried out on strawberries of Honeyoe and Troitskaya varieties, the experiment was two-factor, the replicates were isolated. The determination of NPK in soil and pH were performed according to the generally accepted recommendations for sod-podzolic soils. Weather conditions during the years of research were sufficiently diverse and determined the irrigation rates of plantings. The results showed that the maximum yield of strawberries (13.3 t / ha) is possible with combined fertilization in reserve and with fertigation, but with fertigation, the yield is stable and varies least of all. The highest content of alkaline hydrolysable-nitrogen and plant-available potassium in the average over the years of research was observed in the variant with fertilization in reserve. It has been established that the most optimal way to fertilize strawberries with drip irrigation is a combined application. Drip irrigation accelerates the mineralization of organic nitrogen. Doses of mineral fertilizers should be increased with the age of plantings, while taking into account the level of basic macronutrients in the soil.

The aim of this study was to evaluate the influence of an application of different rates of mineral fertilizers and their combination with associative N-fixing Klebsiella planticola and Enterobacter spp., and sampling period on the number of fungi in Cambisol and grain yield of maize. The investigation was conducted on Mladenovac experimental station and in the Laboratory of Institute of Soil Science, Belgrade, during 2006. Unfertilized soil was used as the control soil. Each of the studied variants was carried out in three replications. The effect of the studied fertilizers was determined three times during the maize growing season, the number of fungi being determined by indirect dilution method on Czapek nutritive medium. The results of the study showed that all fertilization variants studied influenced, more or less, fungal growth in the study soil. However, the applied high content of mineral nitrogen, phosphorus and potassium, as well as their combination with bacterial inoculants brought about the highest increase in the number of fungi during all studied vegetation periods of maize. The highest increase in the number of soil fungi was registered in the second sampling period. The highest increase in the grain yield of maize was obtained by combined application of microbial inoculants and high rates of mineral NPK fertilizers.

This article describes the effect of various doses of mineral fertilizers with trace elements based on pure silicon – “Nanosilicon” on corn plants. It is important to point out that new and perfect varieties are created every year, although, without the use of fertilizers, they will not be able to give the maximum yield. The main nutrients are nitrogen, phosphorus and potassium, often forgetting silicon, even though it also plays an important role in growth and development, as well as in the crop yield; in this research, we studied corn in the central zone of the Krasnodar Territory. Fertilizer “Nanosilicon” increased the height of corn plants by an average of 17 cm or 9.9 %; wet weight by 100.4 g/plant or 17.5 %; yield, as one of the main indicators, by 7.68 kg/ha or 15.4 %.

The experimental studies were carried out on the fields of the Sumy NAU Training Research and Production Complex (TRPC) during 2016–2018.The soil of the experimental plot is typical deep-medium humus, large-dusty and medium-loam black soil on forest trees. The subject of the research was a white mustard variety of Oslava created at the Institute of Feed and Agriculture of the Podillya NAASU, entered in the Register of varieties suitable for cultivation in Ukraine in 2010. The aim of the research is to optimize the nutrition of the white mustard variety of Oslava through the complex application of mineral fertilizers and foliar fertilization under the conditions of the northeastern forest-steppe of Ukraine. The analysis of weather conditions, in particular the hydrothermal coefficient of Selyaninov (HTC), established that 2016 season was wet (HTC = 1.60), 2017 and 2018 were dry (HTC = 0.59 and 0.46). During the research, the cultivation technology was generally accepted in the experimental area, except for the elements studied. The results of the three-year study on the influence of foliar fertilizing under different mineral nutrition backgrounds on the yield of the white mustard variety Oslava are presented. It was found that the application of mineral fertilizers and complex fertilizers for the foliar feeding had a positive effect on the morphometric parameters of the white mustard, in particular, increased the plant height and the number of branches of the first order. The use of mineral fertilizers at the rate of N30P30K30 provided an increase in the yield by 0.34 t/ha, N60P60K60 – by 0.55 t/ha, N90P90K90 – by 0.61 t/ha on an average compared to the control. Therefore, for the maximum yield (2.14–2.21 t/ha) with a mass of 1000 seeds (5.39–5.54 g) of the white mustard under the conditions of the Northeastern Forest-Steppe of Ukraine, foliar fertilizing of Vuxal boron (3.0 l/ha) + Vuxal bioaminoplant 3.0 l/ha) and Spectrum B + Mo (2.0 l/ha) + Spectrum Ascorist (3.0 l/ha) should be applied on the background of N60-90P60-90K60-90, what provided an increase in the yield compared to the control of 0.58-0.65 t/ha.

Agricultural practices in agrocenoses of different ages and in fallow lands of Yamal-Nenets Autonomous Region of the Russian Federation were studied with account for post-agrogenic transformations of soils under cryogenic conditions. Agricultural practices in the YNAR are much consistent with those in Finnish Lapland, Southern Greenland, and remote fishing villages in Alaska. Well-drained areas with sandy, light and medium loamy, sod-meadow or sod-podzolic soils, which are easily warmed and not floating in cases of heavy rainfall, are selected for gardens and fields. The depth of permafrost is reduced in plowed areas and depends on the age of their development. The content of available forms of phosphorus and potassium in the upper layer of fallow soils remains very high even through 5-20 years. The use of agricultural techniques, including mulching, drainage, and application of manure and compost derived from fish, increases soil fertility. Currently, agriculture in YNAR decays for such reasons as remoteness (logistics problems), dependence on weather conditions, difficulties in field cultivation, lack of market for agricultural products, and limited choice of products due to natural conditions and the specifics of the agricultural industry. The small indigenous peoples and the landscapes of the North are inseparable and may be sustainable only based on the traditional ways of life harmonized with the natural and social environments.

Rotatable Design

The response surface methodology (RSM) is a collection of mathematical and statistical techniques useful for the modeling and analysis of problems in which a response of interest is influenced by several variables, and the objective is to optimize the response. The objective of the study was to model the rose coco beans (Phaseolus vulgaris) through an existing A-optimum and D-efficient second order rotatable design of twenty four points in three dimensions in a greenhouse setting using three inorganic fertilizers, namely, nitrogen, phosphorus and potassium. Thus, the objective of the study was accomplished using the calculus optimum value of the free/letter parameter f=1.1072569. This was done by estimating the parameters via least square's techniques, by making available for the yield response of rose coco beans at calculus optimum value design for the first time. The results showed that, the three factors: nitrogen, phosphorus, and potassium contributed significantly on the yield of rose coco beans (p<0.05). In GP3G, the second-order model was adequate for 1% level of significance with p value of 0.0034. The analysis of variance (ANOVA) of response surface for rose coco yield showed that this design was adequate due to satisfactory level of a coefficient of determination, R2, 0.8066 and coefficient variation, CV was 10.30. This study demonstrated the importance of statistical methods in the optimal and efficient production of rose coco beans. We do recommend a randomize screening of all the fertilizer components with which it has influence on rose coco beans be done to ascertain the right initial amount of each fertilizer that could achieve maximum yield than this study realized.

Abstract A modification of an inductively coupled plasma (ICP) emission spectrometer is described that enables the simultaneous determination of nitrogen, phosphorus, and potassium in water-soluble fertilizers. A quartz extension tube is added to the ICP torch to exclude air from the plasma, thus allowing accurate nitrogen determination without adversely affecting sensitivity for other analytes. The modification also requires an 18 mg/L argon coolant flow to protect the tube from the heat of the plasma. Detection limits are 20 mg/L for nitrogen and 50 μg/L for phosphorus and potassium. Three NBS reference salts and 2 commercially available fertilizers were analyzed by the method, and results are in excellent agreement with known values.

The field experiment was conducted to estimate the native nutrient supplying capacity of soil in western terai of Nepal during 2013/14 and 2014/15. The experimental site consisted three areas: Pakadi VDC ward no.-3, Barrohiya of Kapilvastu district; Ramgram municipality ward no.-1, Sanda of Nawalparasi district and Tukuligadh VDC ward no.-1, Rehara of Rupandehi district. The indigenous nutrients supplying capacity of the soil was determined by establishing omission plots for wheat cultivation with six treatments each of 50 m2 and 4 farmers from each site was taken assuming one farmer as one replication. Among the six treatments, -N, -P, -K, –Zn and –B were set to estimate the inherent N, P, K, Zn and B supplying capacity of soil respectively. From two years of experiment, it has been clear that inherent N and K supplying capacity of soil in selected areas is very low. The highest grain yield of 3.33 t/ha and 2.75 t/ha was measured from fully fertilized plots in 2013/14 and 2014/15 respectively and the lowest grain yield of wheat was obtained from nitrogen missing plots in both years (1.74 t/ha and 1.51 ton/ha) followed by potassium missing plots (1.74t/ha). Farmers manage their field in a different way, so large variation was seen even in small area. Nitrogen was found to be most limiting nutrient for wheat growth followed by potassium and phosphorous in all sites. Therefore, use of optimum dose of nitrogen, phosphorus and potassium should be used for efficient nutrient uptake which ultimately increases wheat productivity.

Analysis of modern scientific literature and patents has shown the absence of acid-free production technology of a mechanically activated multicomponent mineral fertilizer containing water-holding substances. Experimental researches connecting with mechanochemical activation and physicochemical properties of Karatau phosphorites prove a possibility of development of a new multicomponent mineral fertilizer. Application of inorganic and organic activators considerably improves qualities of fertilizers because the developed fertilizer mixtures contain nitrogen, phosphorus, potassium, humate and microelements. The suggested technology intends to use wastes of coal mining that leads to presence of humates and microelements in the end product. It was determined, that content of total nitrogen, phosphorus and potassium depends on a form of nitrogen-phosphorus-potassium-containing substances. The given article contains data of researches connecting with use of multicomponent mineral fertilizers in field conditions for cotton cultivation on irrigated light sierozems consisting of soil-forming rocks of loess and loess-type clay loams. The research results show the increase of soil’s fertility and cotton’s productivity. Studying of agronomic efficiency of the new kinds of mechanically activated multicomponent mineral fertilizers at the cultivation of a bean-cereal mixture has been carried out in the Negorelsk experimental nursery-garden of the Belarus State Technical University on a sod-podzol sandy-loam soil and has shown the essential influence on productivity and quality of the bean-cereal mixture. The researches fulfilled on a sod-podzol sandy-loam soil have revealed the essential increase of key indicators of feed productivity. Application of the mineral fertilizers has promoted increase of nitrogen, phosphorus and potassium content in green plants. In so doing content of calcium and magnesium in green mass depends from quantity of the fertilizer used to a smaller extent. An essential difference of crop capacity and feed productivity indicators depending on forms of the applied mineral fertilizers has not been found.

В статье представлены результаты испытания новых отечественных сортов свеклы столовой в Московской области на различных фонах минерального питания: контроль без удобрений, N120P60K180 (расчетная доза) и N240P120K360 (двойная доза). Количество удобрений рассчитывалось согласно схеме опыта по фонам питания и по процентному содержанию действующего вещества. Почва опытного участка относится к типу аллювиальных луговых, среднесуглинистая, насыщенная, влагоемкая. Погодные условия наиболее благоприятно для роста и развития растений свеклы столовой складывались в периоды вегетации 20142017 годов. Особенность погодных условий 20182019 годов неравномерное выпадение осадков, что повлияло на время прорастания семян. Дефицит влаги в период вегетации компенсировали поливами методом дождевания, поддерживая НВ на уровне 7580 . В 20142019 годах изучали сорта свекла столовой селекции Агрохолдинга Поиск для товарного производства: с округлой формой корнеплода Креолка, Мулатка, Русская односемянная, Эфиопка цилиндрической Славянка округло-плоской Смуглянка. Урожайность корнеплодов на фоне без удобрений изменялась от 36,5 (Мулатка) до 47,9 т/га (Славянка). Внесение удобрений в рекомендуемой дозе способствовало прибавке урожая, в среднем, на 20,3 без снижения товарности продукции. Наиболее отзывчивы на минеральные удобрения в расчетной дозе (N120P60K180) оказались сорта Мулатка (33,1) и Смуглянка (29). Внесение удвоенных доз минеральных удобрений не повлекло за собой дальнейшего увеличения урожайности культуры. Сорт Креолка показал на фоне (N240P120K360) наибольшую урожайность 58,6 т/га. Выращивание свеклы столовой с применением удобрений в расчетной и удвоенной дозах уменьшает вариабельность урожайности сортов по годам.Results of testing of new domestic cultivars in the Moscow region on various backgrounds of mineral nutrition: control (without fertilizers), N120P60K180 (calculated dose) and N240P120K360 (double dose) are presented. The amount of fertilizers was calculated according to the scheme of the experiment by nutrition backgrounds and by the percentage of active substance. The soil of the experimental site belongs to the type of alluvial meadow, medium-loamy, saturated, moisture-intensive. Weather conditions were most favourable for the growth and development of table beet plants during the growing season of 20142017. A feature of the weather conditions of 20182019 was uneven precipitation, which affected the time of germination of seeds. The lack of moisture during the growing season was compensated by irrigation by sprinkling, maintaining the HB at the level of 8085. In 20142019, we studied varieties of beet of table selection of Poisk Agro Holding for commercial production: with a rounded root crop Kreolka, Mulatka, Russkaya odnosemyannaya, Efiopka cylindrical root crop Slavyanka round Smuglyanka. The yield of root crops on the background without fertilizers varied from 36.5 (mulatto) to 47.9 t/ha (Slavyanka). Application of fertilizers in the recommended dose contributed to an increase in yield, on average, by 20.3 without reducing the marketability of products. The most responsive to mineral fertilizers in the calculated dose (N120P60K180) were varieties Mulatka (33.1) and Smuglyanka (29). The introduction of doubled doses of mineral fertilizers did not lead to a further increase in crop yield. The Creole variety showed a maximum yield of 58.6 t/ha against the background (N240P120K360) growing table beet with the use of fertilizers in calculated and doubled doses reduces the variability in the yield of varieties over the years.
