Abstract:

The research deals with additional fertilizing of leek cultivars Goliath and Tango with bacterial preparation Organic-balance and mineral fertilizer DripFert N20P20K20 + Ме in combination with adhesive agent of a natural origin Liposam. Field research was performed on the experimental plots of the Department of Vegetable Growing of Uman National University of Horticulture. The research focused on microbiological processes and formation of productivity in the leek crops depending on the combination of preparations.
It has been established that the number of bacteria Azotobacter in the rhizosphere of leek increased 2.8 times after a four-time fertilizing with bacterial preparation Organic-balance and bioadhesive Liposam during vegetation. The maximum number of bacteria, including Azotobacter, in the rhizosphere of leek, was recorded after a four-time fertilization with DripFert N20P20K20 + Ме in combination with Organic-balance and Liposam. The share of influence of additional fertilization on the microbiota of the rhizosphere made up 77–97%.
Leek cultivar Tango produced a larger assimilative leaf surface. Depending on the fertilizing the maximum leaf surface and photosynthetic potential of leek cultivars Tango and Goliath were recorded under combination of Organic-balance + DripFert N20P20K20 + Ме + Liposam. The yielding capacity of variety Goliath was better than that one of the variety Tango regardless of fertilizing. To make the growing technology of leek more environmental friendly it is advisable to introduce in the growing technology bacterial preparation Organic-balance together with Liposam. Utilization of these preparations improves crop yield, which makes up 0.6–0.7 t ha-1 for variety Goliath and 1.1–2.7 t ha-1 for variety Tango correspondingly. The investigated leek varieties had the maximum yields under combined application of Organic-balance + Liposam with fertilizer DripFert N20P20K20 + Ме, which is by 18–24% higher than provided by plants grown without fertilization.

Abstract:

The development and yield of Chinese cabbage is influenced by soil moisture. The objective of this study was to evaluate the physiological indicators, development, and yield of Chinese cabbage (Brassica rapa subsp. pekinensis (Lour.) Rupr.) grown at different soil water tension ranges. Two experiments were conducted (2016–2017) in the Olericulture Sector of the Federal University of Technology of Paraná. Two cultivars of the Chinese cabbage, Eikoo and Kinjitsu, and four soil water tension ranges 13–17, 23–27, 33–37, and 43–47 kPa were studied. Eikoo presented higher relative chlorophyll index, photosynthesis, and fresh leaf mass than did Kinjitsu. Physiological indicators transpiration (5.8 mmol H2O m-2 s-1), photosynthesis (14.5 μmol CO2 m-2 s-1), stomatal conductance (0.31 mol H2O m-2 s-1), and WUE (39.4 kg m-3) were higher at 13–17 kPa soil water tension. Soil water tension ranges with high water restrictions reduced the fresh leaf mass of both cultivars. Fresh leaf mass decreased by 236.2 and 191.7 g plant-1 in the highest soil water tension range in 2016 and 2017, respectively, when compared with the fresh leaf mass at the 13–17 kPa tension range. The lowest water consumption was observed at the 13–17 kPa tension range. The year 2017 resulted in higher internal CO2 concentration, transpiration rate, fresh leaf mass, number of irrigations and water consumption compared to the year 2016. Thus, the irrigation regime for the most optimal Chinese cabbage cultivation should maintain the soil water tension range at 13–17 kPa.

Abstract:

The use of absorbents from Maximarin for growing spinach contributed to its faster germination, increased plant growth and development, and resulted in an increase in yields of commodity products by 2.0–6.1 t ha-1 and an increase in chemical composition. The use of absorbents in open ground for spinach made it possible to obtain the highest amount of contingent net profit for making the drug Maximarin in the form of a gel and the company Eco – with small granules, and in the Krasen Polissia variety – 2,160 and 2,102 USD ha-1, in the Malakhit variety for introduction the drug Maximarin in the form of a gel 1,949 USD ha-1 and the company Eco absorbent with potassium – 1,575 USD ha-1. Profitability for the Matador variety has reached 75%, Malakhit grade – 69–75%, Keb – 3.0–3.2. It was established that in the closed ground application of the drug Maximarin in the form of gel and granules for spinach made it possible to obtain the highest amount of contingent net profit, which was Matador 3,079 and 3,025 USD ha-1, in the Malakhit variety for the introduction of gel 4,304 USD ha-1 and granules – 4,245 USD ha-1. Profitability for the use of drugs for the Krasenʹ Polissia variety reached 84–77%, Malakhit – 118–116%, the bioenergy efficiency ratio – 3.0–3.3.

Abstract:

The density of the plants of Dolichos bean significantly influenced the economically valuable indicators, because there is always competition for light, moisture and nutrients between plants in the life process. The period from mass sprouting to the technical ripeness was reduced with increasing the plant density. Such a pattern was characteristic of all phases of the growth and development of the Dolichos bean. The plants with high population (71 thousand units ha-1) took short period (60 and 119 days) from germination to the beginning of technical and biological ripeness, respectively, turned out to be the earliest ripening crops. The plants are better illuminated, the soil nutrition conditions are improved and the sanitary-hygienic climate of the crops improves with thinned crops, thereby plant productivity has raised. However, the average yield of scapulabeans and unripe Dolichos seeds is regulated by the density of the plants, and increased in density due to the greater number of plants. The optimum density for Dolichos bean was 71 thousand plants per hectare, at which yields of green shoots and green peas were formed 7.3 and 3.3 t ha-1, respectively.

Abstract:

In this study, the geographically weighted principal components analysis as an alternative method for agro-ecological characterization of the region was provided. The spatial and temporal distribution pattern of soybean yield was analyzed by using spatial statistics technology, which provided a good reference for agricultural development planning. The soybean yield was selected for the present study because it is a comprehensive indicator reflecting the production potential of the regional agroecosystems. The organized data set, which included the average per year yields of soybean in 10 regions (206 administrative districts) of Ukraine, was used for analysis. The regular temporal trend, specific for each district, was previously extracted from the time series data. The principal components analysis of the detrended data allowed to identify four principal components, which altogether can explain 58% of the soybean yield variation. The geographically weighted principal components analysis allowed to reveal that four spatially determined processes were influencing the yield of soybeans and had the oscillatory dynamics of different periodicity. It was hypothesized that the oscillating phenomena were of ecological nature. Geographically weighted principal component analysis revealed spatial units with similar oscillatory component of soybean yield variation. Our study confirmed the hypothesis that within the studied territory there are zones with the specific patterns of the temporal dynamics of soybean yield, which are uniform within each area but qualitatively different between zones. The territorial clusters within which the temporal dynamics of soybean yield is identical can be considered as agro-ecological zones for soybean cultivation.

Abstract:

The purpose of investigation is to study the biological and morphological features, to establish the economic and valuable characteristics of the introduced and local forms of Allium ampeloprasum L. in comparison with Allium sativum L. and to study the effect of removal of the scape in the yield. The studies used field, statistical, settlement and analytical methods. The weight of the bulb without removing the inflorescence shoot of the cultivar Sofiivskyi was 28.4–53.3 g smaller than the variety samples No. 2 and No. 3 respectively. With removing the scape the difference increased by 60.5–68.6 g. The yield of No. 2 variety sample Allium ampeloprasum L. without removing the scape was lower than the standard by 1.7 t ha-1 while the variety sample No. 3 exceeded the standard by 1.1 t ha-1. With the removal of inflorescence shoot the yields of variety samples No. 2 and No. 3 exceeded the cultivar Sofiivskyi by 1.6 and 2.2 t ha-1. It has been established according to the researches that introduced forms of Allium ampeloprasum L. have high indicators of economic and valuable characteristics, but they are limited in the first years of cultivation, by the period of adaptation to the new soil and climatic conditions.

Abstract:

The paper deals with the impact of binary mixtures of perennial grasses on the productivity and quality of forage crops that differ in their species composition. The studies have shown that mixed crops exceeded single-species crops in all indicators of forage crops productivity. In total over five years binary crops of Poterium polygamum exceeded single-species ones in all productivity indicators. The plants safety by the end of vegetation was also slightly lower than in single-species crops, which can be explained by greater competition for light, moisture and nutrients. So the safety of Medicago sativa L. was 81.8%, Onobrýchis – 83.6%, Galéga orientális L – 89.7%, Poterium polygamum – 74.6%, which is lower than that of legumes in single-species crops. In all years of herbage use, the binary crops exceeded single-species ones. On average, for 5 years of research, the yield of Poterium polygamum was 25.5 t ha-1, Medicago sativa L. – 22.5 t ha-1, Onobrýchis – 23.7 t ha-1. Among legumes, the maximum yield had Galéga orientális L agrocenosis – 26.1 t ha-1. Mixed crops of burnet with leguminous grasses were characterized for yielding the vegetative mass on average 28.5–30.9 t ha-1. Maximum values of binary Poterium polygamum crops characterized crops with the leguminous plant component of goat’s rue in all years of research. Mixed crops also showed maximum values of dry matter per unit area and amounted respectively 33.52–36.74 t ha-1. The same pattern continued in the yield of fodder units, digestible protein and metabolic energy, their maximum was obtained at the variant Poterium polygamum+ Galéga orientális L.

Abstract:

Potential yield of corn hybrids with a different FAO number is limited by not only rainfall amount, average soil and air temperature throughout vegetation period, but also directly depends on plant density. The study and practical application of special agricultural techniques allows us to limit and mitigate the negative impact of these factors on the productivity of maize, depending on the indicators under study and the soil and climatic resources of the cultivation zone. Therefore, the study of the influence of the seeding rate on the growth and development of corn plants remains relevant. The results presented make it possible to choose optimal seeding rates for corn hybrids of early and middle groups of ripeness (FAO 180-280). Overcrowding from 61,000 to 93,000 seeds ha-1 leads to increase in interstage period ‘sprouting–wax ripeness’ of Rodnik 179SV hybrid for 4 days, of MAS 12R and AMELIOR hybrids–for 2 days, and of MAS 30K hybrid – for 3 days. Hybrids Rodnik 179SV and AMELIOR reached maximum height –217 cm and 214 cm respectively – at seeding rate of 73,000 seeds ha-1, while hybrids MAS 12R and MAS 30K grew up to their 213 cm and 223 cm respectively at seeding rate of 77,000 seeds ha-1. Decrease in seeding rate to less than 73,000 seeds ha-1 and, contrary to it, overcrowding of seeds of more than 77,000 seeds ha-1 leads to decrease in corn hybrid plant height. Agronomically, the most efficient for maximizing early ripe Rodnik 179SV and MAS 12R hybrids yields (6.39 and 6.73 t ha-1) and middle-early ripe AMELIOR hybrid yield (6.81 t ha-1) was the seeding rate of 73,000 seeds ha-1, while the highest yield of middle MAS 30K hybrid (7.21 t ha-1) was at the seeding rate of 77,000 seeds ha-1.

Abstract:

Nowadays, it is an obvious fact that it is necessary to look for new approaches to agriculture, which would ensure the maximum reduction in the dependence of the volumes and quality of the crop on external factors. The use of nanopreparations in crop production is the most promising. The development of new technologies and techniques using nanomaterials, which would ensure high yields and quality of potato products, is relevant and has great practical importance. The research in recent years has established the important role of selenium in the regulation of plant activity.The purpose of this work was to research the effect of selenium nanoparticles and selenium in the form of micronutrient fertilizers on early-maturing varieties of potatoes for table use: adaptive capacity and nutritional value. Selenium nanopowder in the form of a solution contained the optimum nanoselenium concentration applied–0.13 g per hectare seeding rate. The potato tubers were soaked in distilled water 30 minutes before seeding. The treatment of potato tubers with selenium micronutrient, the dose of which amounted to 400 g per 1 hectare, was also carried out before planting. The soil preparation and agrotechnology cultivation generally accepted in the Ryazan region.The research results showed that presowing treatment of potato tubers with selenium nanopreparation had the most favorable effect on the adaptive capacity of plants (heat resistance, water-holding properties), as well as on yield increase, than treatment of tubers with selenium in the form of microfertilizer. The use of Se nanoparticles leads to an increase in the protein and vitamin C content. The Udacha potato variety showed great responsiveness to the entering of various forms of selenium in comparison with others. The use of selenium in the form of microfertilizer leads to an increase in the accumulation of starch and dry matter. These figures were the highest in potato tubers of the Zhukovskiy Ranniy variety.

Abstract:

The present study was done seven elite tomato lines (Solamun lycopersicum L.) of determinate and indeterminate growth with good yield potential and good combining ability, using diallel fashion without reciprocals to produce 21 F1s. General combining ability (GCA) and Specific combining ability (SCA) analysis were conducted, with Diallel-SAS, assessing six yield and component traits. Results showed highly significant differences (p ≤ 0.01) among genotypes, as well as in GCA and SCA effects in all the characteristics that was assessed, with the exception of Days to First Cut. The results revealed that variance contribution to the yield attributed to the crossings had more non-additive effects (SCA) than additive effects (GCA). Furthermore, Line D4 had the greatest effect on yield in terms of GCA, as well in AFW (Average Fruit Weight), NFP (Number of Fruits per Plant) and PD (Polar Diameter) followed by D3 and K3. These lines can be used as donor parent in future tomato-breeding program. Hybrids K3×D4, R1×Y53, D3×IR13 and F3×Y53 had the highest level of SCA, with average yields of 93 t ha-1. These potential hybrids could be exploited at commercial level after critical testing.
