Yield Capacity

The research purpose was to identify high-quality variety features of formation of yield capacity and quality of soybean seeds when applying seniccation and desiccation in the Left-bank forest-steppe of Ukraine. The research subject is Anna, Romance, Vasilkovskaya varieties of soybean, the elements of technology of cultivation (desiccation and seniccation), yield capacity and quality of seeds. The experiment was carried out according to the two-factor scheme in a 4-times repeat at the Institute of Agriculture of the Northeast of NAAS of Ukraine. The research results showed that the duration of vegetation was influenced both by varietal characteristics and the application of desiccation and seniccation. On average, the smallest period from the growing phase to the full ripeness was stated on the variant with Reglon Super 2.0 l/ga and Basta 2.0 l/ga desiccation (36-37 days). The maximum level of yield capacity on the average in 2007-2009 was obtained from Vasilkovskaya variety – 2.50 t/ga. Annushka variety provided significantly lower yields (2.0 t/ha), as it was proved by the calculated NSR05. In terms of yield capacity Romantika variety took an intermediate position of 2.38 t/ga. On the variants with the application of seniccation and desiccation a positive trend of their influence on the yield capacity of soybean seeds in all studied varieties was stated. So, on average, an increase of yield capacity was stated when applying: seniccation 5.0% solution of ammonium nitrate per 0.38 t/ga; 8.0% solution of urea per 0.45 t/ga; Reglon Super 2.0 l/ga per 0.24 t/ga; Basta 2.0 l/ga 0.3 t/ga as compared to the control. Application of seniccation favored the increase of protein content: urea solution by 0.7%; solution of ammonium nitrate by 0.5% compared to the control. On the variants of desiccation the protein content was at (33.9-34.1%). Oil content of the seed of studied varieties ranged from 20.0 to 24.1%.

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.

Introduction of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea to early ripe potatoes of Zhukovsky and Red Scarlett variety on the planned productivity of 40 t/hectare has allowed to achieve a goal. At the same time in control option without fertilizers the productivity was 23,2-24,8 t/hectare. Use of encapsulated urea has led to decrease in productivity and level of profitability by 26,3-30,9%. Early ripe potatoes of Zhukovsky and Red Scarlett variety on natural fertility of the chernozem leached in the northern forest-steppe of the Tyumen region have created average yield of 23,2-24,8 t/hectare for years of researches. Use of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea on the planned productivity of 40 t/hectare has led to increase in productivity on the first variety to 39,5 on the second variety up to 41,4 t/hectare. Introduction of the encapsulated urea has led to decrease in productivity of the early ripe potato tubers studied. At the same time, the peel was gentle and when cleaning it was strongly injured. As to the content of starch (11,9-12,6%) at both varieties the big difference between ex-perience options isn't revealed. The similar picture was observed also according to tastes of tubers. It has made 3,2-3,5 points at Zhukovsky variety and 3,4-3,7 points at Red Scarlett's variety. Profitability level in con-trol option at Zhukovsky variety was 157,3%, at Red Scarlett's variety – 140,5%. In options with non-encapsulated ammonium nitrate and urea the first variety got 172,6-184,1%, second variety – 190,4-207,2%. In option with encapsulated urea at varieties under study the profitability level has decreased 26,3-30,9.

Rotation Scheme

The purpose of the research was to find out the effect of the main fertilization system in the crop rotation scheme on the yield and quality of seeds of moustachioed pea varieties in the Eastern Forest-Steppe of Ukraine. Materials and methods. Field studies were carried out in the period 2016–2020 in the stationary crop rotation scheme of V.Y.Yuriev Plant Production Institute of NAAS of Ukraine. The soil is powerful, poorly leached chernozem. The object of study were seven zoned varieties – Deviz, Tsarevych, Otaman, Oplot, Korvet, Haiduk and Malakhit. The experiment scheme included three backgrounds: 1 – crop rotation (without fertilizers); 2 – organic (manure aftereffect); 3 – organo-mineral (aftereffect of manure + N30P30K30 in the main application). The cultivation technology is generally accepted for the zone. The experimental results were statistically processed by the method of analysis of variance. Results and discussion. In unstable weather conditions 2016–2020 on the unfertilized background, the highest yield level was provided by the varieties Tsarevych (2.33 t/ha), Haiduk (2.28 t/ha) and Oplot (2.27 t/ha) with an excess of the standard variety Deviz by 0.19–0, 25 t/ha. Depending on the year of research, the maximum yield of these varieties varied within 3.04–3.21 t/ha, the minimum yield was 0.77–0.88 t/ha, and the range of variation was 2.27–2.38 t/ha. The productivity of the above mentioned varieties (2.75–2.77 t/ha) exceeded the standard by an average of 0.43–0.45 t/ha on the organic background, and compared with the unfertilized background, the increase in grain yield was 0.44–0.45 t / ha or 18.9–21.5 %. The highest yield (3.04–3.07 t/ha) and an increase in grain (0.77–0.84 t/ha) were provided by the varieties Tsarevych, Haiduk and Oplot on the organo-mineral background. This testifies to their good response to fertilizers and the possibility of cultivation using intensive technology. During the years of research, the maximum yield of these varieties was 4.16–4.39 t/ha, the minimum – 1.27–1.51 t/ha, and the highest range of its variation was from 2.79 t/ha to 2.89 t/ha. The smallest increase in grain on the organo-mineral background of fertilization was obtained in the varieties Malakhit and Korvet – 0.47 t/ha and 0.56 t/ha respectively. At the same time, the range of yield variation over the years was the smallest – 2.43–2.44 t/ha. The most favourable weather conditions for peas were in 2016, 2017 and 2020. Accordingly, this provided the highest level of average yield of varieties in terms of backgrounds: without fertilization – 2.70–2.72 t/ha, organic – 2.87–3.23 t/ha, organo-mineral – 3.14–3.83 t/ha. In the most unfavourable weather conditions of 2019, regardless of the nutritional background, the Tsarevych and Otaman varieties were more resistant to drought. The average yield of these varieties on the unfertilized background was 0.81 t/ha. At the same time, organic and organo-mineral nutritional backgrounds provided a significant increase in the grain – respectively 0.39 t/ha and 0.48 t/ha. Conclusions. On average for 2016–2020, the Tsarevych and Haiduk varieties were the most responsive to fertilization. The increase in grain of these varieties were consistently high – 0.44 and 0.47 t/ha on the organic background (aftereffect of manure) and 0.84 and 0.79 t/ha with the main application of N30P30K30 on the organic background respectively. On average, organic and organo-mineral fertilizer backgrounds for Tsarevych and Haiduk varieties ensured an increase in their productivity 0.38 t/ha and 0.69 t/ha respectively, with a yield under control (without fertilizers) of 2.21 t/ha. The dependence of the quality of pea grain on the variety and nutrition background was revealed. The highest protein content of grain was obtained in less productive varieties of Korvet and Malakhit with indicators, in the control of 24.09 and 23.35%, and on the organic-mineral background – 24.63% and 23.39% respectively. The possibility of the simultaneous increase in yield and protein content in the grain of the Haiduk variety has been established. The most significant gross protein harvest was obtained on the organic-mineral nutritional background in the Haiduk, Oplot and Tsarevych varieties (0.682–0.689 t/ha) with an increase of 16.8–17.8% in comparison with the standard variety Devyz. The increase in the gross yield of protein per hectare, in most varieties, depended on the level of their yield rather than on the protein content in the grain

In the Siberian District, including the Tyumen region, a great contribution into production of foodgrain has been made by valuable and strong varieties of spring soft wheat Iren, Omskaya 36, Novosibirskaya 31. It should be noted that elements of cultivation technology of these varieties for seeds have been developed insufficiently. In the article, the 2016-2018 data have been analyzed according to the productivity and quality of seeds of the chosen wheat varieties in dependence to the level of mineral nutrition (for planned productivity of 4.5 and 6 t/ha). It has been established that in the conditions of the northern forest-steppe of the Tyumen region the level of mineral nutrition for productivity of 4-5 t/ha provided high quality of seeds. In the variant with NPK of 4 t/ha the yield of seeds of the general productivity was 73.0-77.8%, the mass of 1000 grains – 33.9-38.5, the protein content – 15.3-16.8%, the energy of germination – 58.0-67.3%, the laboratory viability – 94.3-96.5%. The main part of seeds (67-74%) sprouted in 5-6 seminal roots and when resowing in 2017-2018 it gave dense, strong shoots. Seeds from the chosen variant had advantage before the control without fertilizers and before variants with higher level of mineral nutrition in many quality indicators.  It has been established that germination energy of seeds closely correlated with protein content (r = 0.72…0.82) and insignificantly – with the mass of 1000 grains (r = 0.27…0.28). Between productivity and energy of germination of seeds the correlation was negative(r = -0,32…-0,40)

In Ukraine and Austria in 2012 − 2014 was researched the features of yield formation and grain quality of six varieties winter wheat of Ukrainian and Austrian selection with different seeding and fertilizing rates. Field research conducted in three field experiments: 1) Right Bank Forest-Steppe of Ukraine (PC NULES “Agronomic Research Station,” v. Pshenychne Vasylkiv district, Kyiv region); 2) zone of sufficient moisture in Austria (Wald und Myulfirtel, p. Kauttsen, North of Lower Austria); zone of unstable moisture of Austria (Nordostlyhes Flah und Hyuhelland, v. Leopoldsdorf, East of Lower Austria). Field multifactor experiments was laid on the same pattern in each of the farms in 2012 – 2014: variety (factor A); rate of nitrogen nutrition (factor B), seeding rate (C factor). Were chosen six varieties, genetically different by baking quality and origin: strong varieties – Lybid, Joseph, Midas, Capo; valuable – Balaton, Polis’ka90. Nitrogen was applicated by next four graduation(with introduction during vegetation under phases: autumn tillering – ВВСН 10-21 / spring tillering – ВВСН 25-29 / booting – ВВСН 30-31 Earing – ВВСН 51- 59): D1 – control without nitrogen; D2 – 120 kg / ha a.i .(0/60/60/0); D3 – 180 (0/60/60/60); D4 – 150 kg / ha a.i. (30/60/60/0). The article presents experimental data from two options of nitrogen supply – con­ trol without nitrogen (D1) and the maximum standards for nitrogen fertilization in three applying – 180 (0/60/60/60) kg / ha a.i. (D3). Seeding rate: 3,0; 4.0 and 5.0 million germinated seeds per hectare. Phosphorus and potassium – 90 kg a. i., applied as background during primary tillage. Preceded of winter wheat – winter rape. In average during years of research the highest yield made – 9.07 tonnes / ha in conditions of East Austria (p. Leopoldsdorf), North Austria (p. Kauttsen) – 9,42 and Right Bank Forest-Steppe of Ukraine (v. Psenychne) – 8.65 t / ha with application of nitrogen (D3). In control variant was observed significant fluctuations in yield – from 3.51 (v. Psenychne) to 5.21 t / ha (v. Leopoldsdorf). There is significant dependence between wheat yields with weather conditions of the year. Find out the optimum seeding grades for conditions of Ukraine and Austria. Estimation of the ecological plas­ ticity and stability of winter wheat varieties were studied. Determinants of wheat quality formation were acertained. The highest mass fraction of protein was achieved by growing strong varieties and introduction of 180 kg / ha N (D3) in all experiments, in average of the study years, in section of soil and climatic conditions (untypical droughty 2012 for v. Leopoldsdorf was excluded). The highest protein content in conditions of Right-Bank Forrest-Steppe of Ukraine obtained at level 15.8%; East Austria – 15.4% and North Austria – 15.0%. Control variant, without nitrogen, allowed to evaluate the potential of soil and variety in the studied environmental conditions – the aver­ age protein content in grain in conditions of Austria reached 12.2% (v. Leopoldsdorf) and 12.4% (v. Kauttsen), of Ukraine – 11.6% (v. Psenychne).

ABSTRACT The objective of this study was to identify the spatial distribution of the physiological quality of soybean seeds during storage from a production field of 39 hectares using geostatistical techniques in the 2012/2013 harvest. Seeds were sampled at geo-referenced points for the determination of physiological quality and spatial dependence analysis. The results were submitted to analysis of descriptive statistics, Pearson's linear correlation and geostatistics. The grid of one point per hectare and a georeferenced sampling mesh with spacing of 100 meters between points was efficient in the evaluation of the spatial variability. It was verified the existence of a negative correlation between the variable protein content and bed bug attack and a significant correlation between the intensity of bed bug damage and the protein content with the variables related to seed quality. Physiological quality is not uniform, particularly in relation to vigor, providing better diagnosis through interpolation maps. Precision agriculture, coupled with the monitoring of seed quality during storage, indicated spatial variability of quality from harvest to the end of storage. Areas with high rates of bedbug and unit damage presented low quality physiology and reduced protein levels. The geostatistics allows to determine the spatial distribution of the physiological quality of soybean seeds in the area of seed production, facilitating the decision making, regarding the areas to be harvested.

AbstractThe article presents the results of the research on the peculiarity of response ofPinus sylvestrisL. growth in height and diameter in young pine forest stand of the Left-Bank forest-steppe of Ukraine under the influence of surface fire that happened in May 2011. Forestry taxation, comparative ecology, standard dendrochronological methods were used. Response of trees was different for the height growth and the radial increment in the year of fire (2011). The radial growth got depressed in the year of fire; at the same time, the height of trees showed positive trend of growth against the background of favourable weather conditions. The growth in height was more ductile and completed its recovery to a particular level in 2014, unlike the radial growth, which recovered only in 2016. The relationships between radial growth on one side and stand sanitary state and height of bark char on the other were approximated by quadratic and cubic regression equations. Dynamics of pine growth depends on climatic factors also. Percentage of the late wood should be used to assess the condition of stands after fire. Research of post-pyrogenic development of forest ecosystems will allow more effective planning of forest management measures, and also allow the adjustment of the monitoring duration for pine forest stands damaged by fires.
