Relevance. The most popular cucumber in Russia is pickling type (lenght 10-12 cm). There are not a lot of varieties this type cucumber for high wire and LIT crop in Russian seeds market.Methods. Were tested russian varieties F1 Ciborg, F1 Bavarets (Gavrish company) in compare F1 Bjorn (Enza Zaden, Netherlands) – the most popular in Russia now. Russian customer prefer pickling type because of traditional Russian cuisine. Prices of pickling type cucumber at autumn-winter time in 1-1.5 times more than middle size type cucumber. We had artificial light 240 Wt/sq.m, sodium lamps, our substrate was rockwool – Belagro (company from Belarusian republic). This rockwool have normal quality for short crop (3-4 month for growing cucumber), our plant density 2.76 plant/sq.m it was optimal for our light conditions (natural light in our region and artificial light).Results. Fourteen days after we put plants on slabs we had problems with plants of both russian varieties (F1 Ciborg and F1 Bavarets). We saw yellow parts in leaves, decrease length of stems, lost flowers. We made a decision about too high level of artificial light. We had only one opportunity for decrease it switch off 50% of lamps. We made it and we had 120 Wt/sq.m that. Therefore, we spent 50% less electricity for russian varieties. We think varieties F1 Ciborg and F1 Bavarets not very good for winter crop and we had good results because in our situation we have winter-spring crop, and every day the part of artificial light decrease and the part of natural light increase. F1 Ciborg had a problem with CGMMV and was deleted in 24th week of 2020. But we suppose it depend from a lot of conditions: quality of labor, protection plants. We think it is necessary more additional research. Total yield (for ten weeks of harvesting in winter-spring crop) F1 Bavarets – 32.4 kg/sq.m., F1 Ciborg – 31.9 kg/sq.m more then had F1 Bjorn – 28.9 kg/sq.m. The best marketable condition was F1 Ciborg, the second F1 Bjorn.

Summary. The effect of plant density on growth, development, yield and quality of kabocha (buttercup squash) (Cucurbita maxima) was examined during 1992–93, at a field site in Cambridge, Tasmania. Plant densities ranged between 0.5 and 4.7 plants/m2. Marketable and total yields were fitted to a yield–density model. Total yield followed an asymptotic trend, approaching 33 t/ha at 4.7 plants/m2, while marketable yield had a parabolic relationship with density. Marketable yield increased to a maximum of 18 t/ha at 1.1 plants/m2, while declining at higher densities because of increased numbers of undersized fruit. Yield of vine marked and callused fruit did not vary with density, but represented a significant proportion of the total yield at all densities. High plant density reduced vegetative growth per plant due to competition for limited resources; as shown by decreased leaf area, number and length of vines, and plant dry weight. Yield tended to decline at high densities because of fewer female flowers and increased fruit abortion per plant. Plants at low densities had more vegetative growth but decreased yields, as increased abortion of fruit relative to the higher plant densities left only 1–2 large fruit per plant. Economic returns varied with plant density. At high densities, variable costs increased (particularly due to high seed cost) while gross income declined reflecting the relationship between marketable yield and plant density. The gross margin therefore declined at high densities.

investigations were made on the relationship between plant density and plant height, and on the yield, thousand seed mass, and ratio of diseased and broken seeds of varieties with different seed sizes. Experiments were carried out to analyse the effects of potassium on the yield, bacterial diseases and nutritive quality of the seed of bean varieties. Three dry bean cultivars representing the small, medium and large seed size groups were investigated. Six plant density treatments were chosen based on theoretical seed norms, taking the germinative value of the seeds into consideration. The correlation between plant density and yield average showed that the volume of yield increased for varieties with large and medium-sized seeds up to a plant density of 285-400 thousand/ha, after which it declined. On the basis of the results, yield averages at plant densities of 285-334 thousand plants/ha were 0.17 t/ha higher than those achieved at low density (200 thousand plants/ha). At greater plant density the plant height increased in the case of large-seeded varieties and there was a considerable decrease in the thousand seed mass. With an adequate water supply a high level of potassium decreased the number of pods and seeds per plant compared with the basic level, which gave a yield of 2.5 t/ha. The use of high rates of potassium fertilizer decreased the number of infected seeds, but the differences were only significant for the small-seeded variety. A moderately high potassium level was advantageous for food quality, particularly during drought.

The correlation between plant density and yield average shows that the volume of yield increases in varieties of large and medium-size seeds up to a plant density of 285-400 thousand/ha, after which it declines. On the basis of the results, yield averages at plant densities of 285-334 thousand plant/ha are 0.17 t/ha higher than those achieved at low density (200 thousand plant/ha). High levels of potassium fertilizer did not enhance the yield of dry beans. With adequate-water supply the high level of potassium decreased the number of pods and seeds per plant compared with a basic level of fertilizer, which could ensure 2.5 t/ha yield.

ABSTRACT Obtaining a high yield of good quality fruits is one of the main challenges of the tomato crop. The enhancement in plant density promotes a reduction in the fruit fresh mass and an increase the yield per area. On the other hand, commercialization parameters take into account number and fresh mass of fruits. This study aimed at evaluating the yield and fruit quality of indeterminate growth hybrid tomato (Rebeca), cultivated in a hydroponic system, with different planting densities and number of bunches per plant. The experiment was conducted under greenhouse conditions, in a sub-irrigation system containing expanded clay as substrate. A split-plot randomized block design, with three replications, was used. In the plots, four planting densities (11.1 plants m-2, 8.3 plants m-2, 6.6 plants m-2 and 5.5 plants m-2) were allocated and, in the subplots, the number of bunches per plant (one or two). The total yield was influenced by the interaction planting density x number of bunches per plant. The treatment that allowed the highest yield was 11.1 plants m-2 with two bunches, with 22.61 kg m-2 or 226.1 t ha-1, in a crop cycle of 134 days. The observed variations for the nutrient contents of leaves and fruits of tomato plants with one or two bunches, at densities of 5.5-11.1 plants m-2, do not compromise the fruit quality nor influence the production of tradable fruits, using the hydroponic system.

ABSTRACT Watermelon farming has a high economic and social importance. In parallel, the consumers’ demand for distinctive products has led to niche markets, where mini watermelons stand out. This study aimed to assess the agronomic performance and fruit quality of mini watermelon grown in coconut husk fiber, as a function of number of stems per plant and plant density. The Smile hybrid was used, as well as a randomized block design, in a 2 x 2 factorial scheme, with eight repetitions, being the first factor the number of stems per plant (1 or 2) and the second the number of plants per pot (1 or 2). Characteristics related to yield, physiological parameters and fruit quality were assessed. Interaction between number of stems and plant density was only observed for leaf area, average fruit fresh weight, total yield and percentage of large fruits. The factors were evaluated separately for the remaining traits. Two-stemmed training systems, at a density of one plant per pot, produce the highest yield, without compromising the quality of the fruits, being, in these conditions, the most suitable method for farmers.

The article presents the results of research on the yield of crushed cereals, its culinary quality depending on the index of grain peeling of different varieties of spelled wheat. Holikovska wheat grain and LP 1152 line were used as raw materials for cereal production. A significant (p≤0.05) effect on the total yield of crushed cereals of different grain peeling duration was established. A decrease in the total yield of cereals was accompanied by an increase in the yield of flour. The use of larger grains (line LP 1152) provides a significant increase in the total yield of crushed cereals. Peeling of grain helped to reduce the total yield of cereals and crushed cereals № 1 and № 2. At the same time, there was an increase in the yield of fine fraction of cereals № 3. The use of grain with a higher content of shells provides a higher yield of larger grains. The total yield of wheat spelled from line LP 1152 varied from 83.6 to 86.0 % depending on the grain husking index. When using grain, the yield of cereals № 1 was 9.3±0.3 %, cereals №2 – 54.5±0.6, cereals № 3 – 22.2±0.9 %. The use of husking of spelled wheat grain reduced the yield of cereals №1 to 6.0±0.3 %, cereals № 2 – to 50.4±0.4 %. The grain yield №3 increased to 27.2±0.7 % in the variant with the highest peeling index. The lowest amount of flour (9.0 %) was obtained using unhulled grain. Peeling causes an increase in yield to 11.5 % with the use of hulled grain (peeling index 11 %). No association has been established between mechanical losses, category I, II wastes, and the use of grain husking. The total yield of Holikovska spelled wheat groats varied from 77.5 to 76.0 % depending on the grain-husking index. The yield of cereals by numbers varied like a line of spelled wheat. The main importance in changing the duration of cooking, boiling ratio and organoleptic characteristics is the coefficient of grain peeling. Varietal features did not have a significant impact and had similar meanings. The reduction in cooking time was observed with an increase in the index of grain peeling, as well as with the use of cereals of a smaller fraction. The main factor that influenced the improvement of the overall culinary quality of cereals is the improvement of color and consistency during chewing because of increasing the peeling index. With a grain-peeling index of 3–6 %, the culinary quality was at a high level. Very high culinary quality of cereals is ensured by the use of grain husking for 120–160 s (peeling index 9–11 %). When producing crushed groats from spelled wheat grain, it is optimal to use LP 1152 grain with a peeling index of 3–6 %. This ensures a high total yield of cereals (85.0–84.6 %) and high culinary quality of porridge. Key words: spelled wheat, grain, peeling, crushed groats, culinary evaluation.

SUMMARYThree maize hybrids (Kelvedon 75A, Kelvedon 33, and Anjou 210) were grown under irrigated conditions at a wide range of density from 5·4 to 21·6 seeds/m2 at a rectangularity of 1:1. For yield of digestible dry matter at the time of silage harvest (7 October) a seed rate of 10·8 seeds/m2 (44000/acre) appeared adequate, as doubling the density to 21·6/m2 only resulted in 7% higher yield. K 33, which is a late·maturing hybrid bred for silage in south-east England (50·5–52·5 °N) produced the highest total yield of digestible dry matter due to a high yield of digestible stem. However, the dry matter % of this material would be too low for good ensilage and for a high level of feed intake. In the early grain hybrid K 75 A, 62% of the digestible dry matter was contained in the ear at the silage stage which improved the digestibility and dry matter % of the whole crop with only a 12% lower yield than K 33.The optimum density for grain was 10·8 seeds/m2. This is a higher response to density than is believed to occur in field crops in Britain as in these experiments the seed was planted on the square and irrigation was applied at moisture sensitive stages. The parabolic relationship between grain yield and density was closely related to grain number per unit area. At 10·8 seeds/m2 all three hybrids were of similar yield and grain number per unit area. In Anjou 210 this was achieved with one large ear per plant, whilst for the two Kelvedon hybrids mean ear production was 1·34/plant but with 27% fewer grains per ear.

Research background and hypothesis. Replete schedule of competitions and intense training are features of contemporary team sports. Athletes, especially the most involved ones, may not have enough time to recover. As a consequence, aggregated fatigue can manifest in some undesirable form and affect athlete’s performance and health.Research aim. The aim of this study was to evaluate the changes in heart rate recovery (HRR) and investigate possible relations with sport-specifi c measures of effi cacy in professional basketball players during competition season.Research methods. Eight male high-level basketball players (mean ± SD, body mass, 97.3 ± 11.33 kg; height 2.02 ± 0.067 m, and age 23 ± 3.12 years) were investigated. The same basketball specifi c exercise was replicated several times from September till April during the practice sessions in order to assess the personal trends of HRR. Heart rate monitoring was performed using POLAR TEAM SYSTEM. Investigated athletes were ranked retrospectively according to the total amount of minutes played and the coeffi cients of effi cacy. Research results. There were signifi cant differences in the trends of HRR between the investigated players. The most effective players showed decreasing trends of HRR in all cases of ranking.Discussion and conclusions. Research fi ndings have shown that the quality of heart rate recovery differs between basketball players of the same team and could be associated with sport-specifi c effi cacy and competition playing time.Keywords: adaptation, autonomic control, monitoring training.

The continuous modernization of the education system makes the problems of the quality of teacher training increasingly relevant. Moreover, the measures taken to improve the system of teacher education are largely confined to the introduction of new organizational and managerial mechanisms and practically do not affect the internal content and technological structure of the teacher training process.Modern pedagogical universities are constantly looking for innovative models of training teachers that will be able to solve non-standard social and professional tasks. However, recent studies in this area do not fully take into account the nature of pedagogical activity and conditions of its formation. Thus, the need arises for a special study of the processes and means of updating the content and technologies of teacher training in order to control the level of students’ professional competencies development, as required by educational and professional standards. This means the creation of a special educational system in a pedagogical university, which can provide a harmonious and synchronous mastering by future specialists of both subject knowledge and methods of pedagogical activity.The article provides a theoretical study aimed at identifying key patterns of designing a new content for teacher education, the basis of which is the formation of a future teacher as a subject of his own professional activity. The author describes the experience of using a subject-oriented model of education, implemented at Bashkir State Pedagogical University n.a. M. Akmulla. The effectiveness of this model is confirmed by the high level of students’ mastery of designing methods and constructing the educational process, as well as their positive experience in the implementation of educational activities.
