Control Analysis

Barley is a crop, requires the availability of available nutrients in the soil, especially at the be-ginning of the growing season. The aim of the research was to determine the effectiveness of the aftereffect of using vermicompost when growing spring barley on different backgrounds in the Donetsk region. The studies were carried out according to the methodology of the field experiment of B. A. Dospehova. Research methods: field, supplemented by analytical studies, measurements, calculations and observations. The studies were conducted in 2017–2019 by laboratory-field method in field crop rotation in the experimental sections of the Donetsk SSES NAAS. The repetition in the experiments is 3-fold. The location of the plots is systematic. The soil is alkaline-chernozemic carbonate, having an average supply of mineral nitrogen and mobile phosphorus, low – potassium. The humus content of 4,2 % indicates a high potential soil fertility, but to realize the potential of the culture, additional application of phosphorus-potassium fertilizers is necessary. The technology for growing crops is generally accepted for the farms of the region, with the ex- ception of the factors studied. Variety of barley spring Avers. The experience scheme provides for: control (without fertilizers); background – saturation of crop rotation with vermicompost granular 2 t/ha; background + N30P30K30; background + N60P60K60; N30P30K30. The use of organic fertilizers under the predecessor in crop rotation provided improve nutriti-on conditions for plants, which positively affected the growth and development of spring barley plants. So, on the variants with the use of mineral fertilizers, the highest indices of the number of productive stems and the structure of the crop were noted in the background. The variant where N60P60K60 was added in the background produced the largest mass of 1000 grains – 49,8 g, which is 4,6 % higher than the control. Analysis of the study indicates the positive effect of the aftereffect of organic fertilizer (ver-micompost) on the yield of spring barley. The maximum yield of spring barley was obtained against the background of aftereffect of vermicompost 2 t/ha and the application of mineral fertilizers N60P60K60 – 5,05 t/ha, but due to high production costs, the profitability level is 114,9 %. The application of organic fertilizers under the background provides a yield of 3,67 t/ha and the highest level of profitability of 140,6 %. The optimal technological option provides for the introduction of mineral fertilizers in the norm N30P30K30 amid predecessor saturation with vermicompost. This allows increasing the yield up to 4,90 t/ha (by 1,46 t/ha or 42,4 % to the control) and obtaining a profitability level of 136,1 %. The use only of mineral fertilizer N30P30K30 in severely arid weather conditions of the steppe zone allows increasing the yield by 0,70 t/ha compared to the control but, due to the high cost of pro-duction, leads to a low production profitability of 99,6 %. Key words: spring barley, background, vermicompost, mineral fertilizers, yield, economic effici-ency.

Different Doses

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The Impact

The issue of scientifically sound fertilizer application in fruit plantations, which are long-term and re-grown in one place remains insufficiently studied. To solve this problem is possible only in long-term stationary studies, as the impact of different fertilizer systems on changes in soil properties and tree productivity for a long period of their use. The results of researches of long-term fertilizer influence on the main fertility indices of dark gray podzolic heavy loam soil and productivity of repeatedly grown apple trees of Idared varieties on seed and vegetative (M4) rootstocks and Calville snow on seedling rootstock are considered. During the 85-year period of growing the first and second generation of apple trees in the experimental garden, the organic fertilizer (40 t/ha of cattle manure), mineral fertilizer (N120P120K120) and their combination (20 t/ha of manure + N60P60K60) were applied in the old plantation every two years in autumn in plowing in rows at 18–20 cm, and in the new repetition: manure, phosphorus and potassium fertilizers as well, and nitrogen fertilizer in half doses annually in spring for cultivation or disk plowing to a depth of 12–15 cm. As a result of research it was found that organic fertilizer better than mineral fertilizers provided the formation of soil fertility (humus and mobile compounds and forms of nutrients, soil reaction) and yield capacity of experimental apple trees, which for all years of fruiting exceeded the total yield of Calville snow and Idared on seedling and vegetative rootstocks, respectively, by 34.8, 27.7 and 23.4 % compared with the yield of the control non-fertilized areas and 16.0, 15.8 and 13.2 % – on those fertilized with N120Р120К120. Similar parameters of soil fertility indicators are formed by the organo-mineral fertilizer system with systematic long-term application of half the norms of organic and mineral fertilizers of manure 20 t/ha together with N60P60K60. However, the mineral system (N120P120K120) significantly less increases the humus content and content of macronutrients available for plant nutrition and does not enrich the soil with trace elements, acidifies the reaction of the soil environment

Corn is among the short-cycle annual species used in agroforestry systems due to its adaptation to intercropping. Thus, this study aimed to evaluate the corn yield, cultivar BIO Z 2365, in two types of agroforestry systems. The experiment was carried out in a forestry agroforestry system in two treatments: mechanized with mineral fertilizer and semi-mechanized with organic fertilizer. The experiment was carried out in a forestry agroforestry system (AFSs), with two treatments, mechanized with mineral fertilizers (MEC) and semi-mechanized with organic fertilizers (SMEC). Each treatment was composed of four crop strips (4 x 24 m) distributed with plants arranged at a distance of 0.50 m between lines, totaling four plots per treatment. A random collection of 20 plants per strip was used, and different variables related to production were evaluated. The productivity was estimated using the EMATER and Reetz methods and by estimating the direct yield. The t-test was adopted to verify the difference between treatments. The mechanized system was superior for all the variables evaluated, obtaining average yield of 41.6 bags ha-1. In the semi-mechanized system, the average yield was 29.2 bags ha-1. The performance of cultivar BIO Z 2365 was better in the mechanized system. However, the results revealed that the cultivation of short-cycle crops, despite technological restrictions in the experimental area, can mean an increase in income for small producers or act in reducing the costs of the implementation and maintenance in agroforestry systems; operating as an agent of economic sustainability.

The results of a study of the effectiveness of the joint application of potato mineral and organic fertilizers are presented. The studies were carried out in 2017–2018. on the drained lands of the Tver region. Objects of research - potatoes of the Scarb variety, mineral and organic fertilizers in various doses. Organic fertilizers are products of the processing of organic raw materials based on fermentation processes - multipurpose compost (KMN) and BiGuEM. Mineral fertilizers - ammonium nitrate, double superphosphate and potassium chloride. In the work we used experimental methods - field experiments and theoretical research methods - mathematical statistics. Evaluation of the optimal fertilizer doses showed that BiHuEM organic fertilizer at a dose of 3 t / ha, when used together with mineral fertilizers at a dose equivalent to 3 t BiGuEM, provided potato resistance to late blight compared to the version where KMN was used - almost 8% in 2017 and 12% - in 2018, and compared with the option without the use of fertilizers (control) - by 61% and 23%, respectively. This combination of fertilizers provided the maximum yield (both general and marketable) in comparison with the control by 45% when calculating both types of yield in 2017, and in 2018 by 38% of the total and 53% of the commodity yield. A greater increase in potato yield was also revealed in the variant with BiGueM in comparison with the variant of using KMN - by 4.5% and 5.7% in 2017 and in 2018 by 6.1% and 10%, respectively. An increase in the quality of potatoes was noted, which is confirmed by the low content of nitrates in them, as well as by the increased content of starch, which was especially noted in 2017 - 34.3 g / kg and 15.99%, respectively.

SummaryThe purpose of this study is to evaluate the effect of organic farming technologies on the yield of alternative types of wheat: hard wheat (Triticum durum), spelt (Triticum aestivum ssp. spelta) and a common variety of (soft) winter wheat (Triticum aestivum ssp. vulgare). The experiment was carried out during 2010-11 and 2011-12, at the Radmilovac experimental field of the Faculty of Agriculture in Belgrade, according to the randomized block design in four replications. In addition to the control treatment (without fertilizers), microbiological fertilizers were applied in topdressing (alone) and in combination with organic fertilizer before sowing. Crops were grown under a four-crop rotation on leached chernozem in the rainfed water regime. The average yields of the varieties examined were not significantly different depending on the growing year, whereas fertilization showed a highly significant effect on the grain yield. The combined application of microbiological and organic fertilizers resulted in the highest yields in both years (5,209 and 4,992 kg ha-1, respectively). The selected wheat varieties exhibited different responses to the treatments applied. The highest yield was observed in the common soft wheat variety examined (5,170 and 5,611 kg ha-1), whereas the lowest in durum wheat (3,138 and 2,429 kg ha-1). The analysis of experimental factor interactions showed that statistically significant effects on the yield could be attributed to the year-fertilization interaction. The wheat yields obtained are similar to those observed in the conventional production system due to favorable weather conditions and a proper selection of the type and sequence of crops that are part of the four-crop rotation (winter wheat, maize, spring barley + red clover, and red clover).

The article presents results of the research concerning impact of mineral, organic and organic-mineral system of fertilization with a different share of organic fertilizers on the fertility of dark-grey podzolic soil during the period of four cycles of a short cycle cereals-growing crop rotation. It is argued that application of organic-mineral fertilization with the share of 15.0 ton/ha of organic fertilizers secures increase of the content of total humus in the soil (+ 0.24% and + 6.24 ton/ha to the indicator of the first cycle) after the fourth cycle of a short cycle field crop rotation. Mineral system of fertilization does not supply an extended reproduction of humus share in the soil (-0.06% and -1.56 ton/ha, as compared to the similar variant of the first cycle of crop rotation). It is determined that the dynamics of the content of the main elements of mineral nutrition in the soil also depends on fertilization system. Under conditions of stationary field experiment the largest share of low-hydrolysed compounds of mineral nitrogen (139 mg/kg of soil), phosphorus (113 mg/kg of soil) and potassium (109 mg/kg of soil) in one layer (0–20 cm) was secured by organic-mineral system of fertilization with the share of organic fertilizer of 15 ton/ha at the end of the fourth cycle of crop rotation. Comparing to the first cycle, the share of the main nutrition elements in the variant increased by 27.1, 36.1 and 39.7% respectively. Such a system of fertilization supplied the highest level of the yield of agricultural crops during the four cycles of crop rotation. However, one should note that payback of yield was reduced from a cycle to cycle in case of fertilizers application. Key words: fertilization system, crop rotation, humus content, nutrition elements, yield.

Research on the effectiveness biomodified mineral fertilizers were carried out on the basis of Ulyanovsk SRIA – SamSC RAS branch during the rotation grain fallow five fields crop rotation: pure steam – winter wheat – spring wheat – barley – oats in 2013-2018. The field experiment scheme included options (except control): with the introduction of biologics BisolbiFit (introduction with seeds that were treated before sowing), azofoski N15P15K15, in pure form, modified with biopreparation azofoski in the same dose N15P15K15, half a dose of modified azofoski (N7, 5 P7, 5 K7, 5). The effectiveness of fertilizers and biopreparations in crop cultivation was studied on three backgrounds: natural (control), ammonium nitrate at a dose of 40 kg ai/ha (NH4NO3), and modified ammonium nitrate at a dose of 20 kg DW/ha. It was established that modification of azofoski with Bisolbifit biopreparation can significantly increase the coefficients of use of elements from it by plants. The latter allows to reduce the dose of fertilizer, without reducing the productivity of cultivated crops, twice. Long-term cultivation of crops using only mineral fertilizers and biological products led to a relative decrease in the humus content in the soil and its acidification. For 6 years, the content of humus in the arable layer of leached chernozem decreased by 0.12 %, and the acidity of the soil solution increased by 0.5 pHKCI units. In the conditions of the Volga forest-steppe, when cultivated on chernozems, the highest-yielding winter wheat is (up to 4.00 t / ha or more, in our experiments 3.88-4.80 t / ha). The average yield of spring wheat was 2.68-3.31 t / ha, spring barley 2.67-3.21 t / ha, oats 2.15-2.71 t / ha. The highest productivity of crop rotation was observed against a background with modified ammonium nitrate at a dose of 20 kg ai/ha (½NH4NO3) when applying modified azofoski (N15P15K15). Grain harvest for 2013-2018 in this variant was 13.36 t / ha, exceeding the control variant on this background by 1.31 t / ha.
