Abstract:

Crop yield is a result of the interaction between plant genetic traits, soil properties, agrotechnology and climatic regimes. Low yield tend to be formed in regions where it is limited to the extent of water availability, heat stress and the short duration of the grain filling period. High temperature and drought stress are projected to reduce crop yields and threaten food security. The article presents the results of studies on the effectiveness of treatment of spring barley crops with modern growth-regulating drugs on the background of mineral fertilizers, carried out in different weather and climatic conditions in 2013–2017 yrs on the Southern chernozem in the conditions of Steppe of Ukraine. It was studied the influence of weather and climatic conditions, varietal characteristics of spring barley and nutrition variants on the formation of grain yield. It was determined that the cultivation of spring barley, the introduction of pre-sowing cultivation of mineral fertilizer at a dose of N30P30 (background) and the use of crop foliar fertilizing at the beginning of the phase of stooling and earing by the complex organo-mineral fertilizer Escort bio created favorable conditions for the growth and development of plants of the studied varieties, which in turn had a positive effect on grain yield. Thus, according to this variant of nutrition, on average, during the years of research, it was formed the yield of 3.25–3.61 t ha-1 grains depending on the studied variety.
Results of researches showed that weather conditions during the years of research significantly influenced on the productivity of spring barley varieties. In 2016 the amount of precipitation was the highest (174.0 mm), the temperature during vegetation of spring barley was +14.9 °C. In 2013 the amount of precipitation was the lowest (67.4 mm), the temperature was +18.5 °C. The lowest crop yield was formed in 2013, and the highest yield was formed in 2016. Studies showed that the influence of weather factors in various interfacial periods of growth and development of spring barley was significant enough for the manifestation of signs of yield and its elements and is more dependent on rainfall.

Abstract:

Field pea (Pisumsativum L. ssp. sativum) is a universal pulse crop. One of the actual problems in its production is the influence of weather condition on the variability of pea economic characters and its properties. The purpose of the research (2009–2018) was to compare the vegetation period and interstage periods of the Hangildin and Chishminskiy 229 pea varieties with weather condition and seed yield. According to the results of the conducted research, it can be seen that the duration of the vegetation period and the yield of field pea grain was influenced by weather condition. The average daily air temperature affected the duration of the sowingsprouting period in pea varieties Hangildin and Chishminskiy 229. The duration of the two periods (sprouting-flowering and flowering-ripeness) was influenced by features of the used varieties and the temperature condition (r = -0.472, the link is significant and r = -0.788). The duration of the sprouting-ripeness period depended on the average daily temperatures (r = -0.481), the amount of precipitation (r = 0.937), and the HTC (hydrothermal coefficient) (r = 0.927). Precipitation increased the duration of the full vegetation period (r = 0.892). On average, over 10 years of research on field pea it should be noted that there wasa close relationship between the duration of its vegetation period (r = 0.844), the duration of the flowering-ripeness period (r = 0.679) and the yield of seeds. The relationship between the seed yield and the sowing – sprouting period (r = 0.451) and between the seed yield and the sprouting – flowering period (r = 0.446) was revealed. The connection was found positive. The connection with the average daily air temperature of this period was negative (r = -0.213). The results of the research can be successfully used during cultivation of domestic and foreign varieties of field pea. In international practice, the results of this experiment can be successfully applied in selective improvement of field pea and the development of new, high-tech varieties.

Abstract:

The aim of this research was to study a promising MD 1–17 Melissa officinalis L. subsp. altissima (Smith.) Arcang. variety sample obtained in the collection of the gene pool of the Research Institute of Agriculture of Crimea (RIAC) in comparison with Krymchanka (selected in the RIAC) and Lada (selected in the All-Russian research Institute of medicinal and aromatic plants (VILAR) varieties of lemon balm M. officinalis L. subsp. officinalis. In 2017–2019, in the Department of Essential Oil and Medicinal Plants of the RIAC,a competitive variety trial of lemon balm varieties was conducted in accordance with the methodological recommendations for the selection of essential-oil plants. A territory where this study was conducted belongs to one of the five agroclimatic regions – the upper piedmont, warm, not enough humid; to the northern subarea with moderately mild winters. Weather conditions during the years of competitive variety trial varied significantlya fact that allowed assessing the adaptability of studied variety samples and forecasting the nature of productivity potential realization in different growing conditions. As a result, it was found that MD 1–17 variety sample significantly exceeds other varieties in terms of yield of fresh raw materials, on average, by 62.2 and 77.4%, and in yield of air-dried raw materials, on average, by 32.2 and 52.2%, respectively. In terms of obtaining essential oil from air-dried raw materials, this variety sample exceeds the best in this parameter Crimean variety Krymchanka by 56.3%. Basic components of its essential oil are caryophyllene (25.3–35.9%) and germacrene D (17.7–31.2%) with almost complete absence or insignificant amount of citral (0.1–7.3%); the proportion of latter in essential oils of Krymchanka and Lada varieties can reach 36.6% or more. Novelty of this study includes the creation of the first variety of a new promising essential oil plant –M. altissima. Raw materials of this variety and products of its processing may be of interest for different ways of use, including the perfumery and cosmetics industry, for food purposes as a component of tea compositions, etc.

Abstract:

Organoleptic, structural-and-mechanical indicators determine the suitability of fruiting vegetables for harvesting and preservation, as well as the ratio of separate parts of the fruit. All these indicators affect the quality of products.
Experimental work was carried out in the conditions of the laboratory of the Department of Technology of Storing and Processing of Grain. A complex of organoleptic, commercial, physical and thermophysical indicators of eggplant, sweet pepper and tomato fruits were developed in the work to determine the time of their harvesting.
It was determined that physical density and mechanical strength in the fruits of sweet pepper of technical degree of ripeness were 6% higher than in the fruits of biological degree of ripeness.
Peculiarities of the ripeness degree significantly affected the amount of inedible part of the fruit (seeds, seed cavity and peduncle), which was 1.2 times less in sweet pepper fruits of technical degree of ripeness than biological degree of ripeness.
Considerable varietal difference of eggplant fruits by the amount of edible and inedible parts of the fruit was determined. Peculiarities of the variety also significantly affected the density and hardness of the fruit.
Red tomatoes fruits of Iskorka variety had tender pulp consistency and relatively low fruit density (0.88 g cm) and mechanical strength (3.00 kg cm). The objective organoleptic, structural-and-mechanical indicators of fruiting vegetables were determined depending on their degree of ripeness; to determine the optimal time of harvesting the fruits of eggplant, sweet pepper, tomato.

Abstract:

The aim of the study was to determine the efficiency of the barley treatment crops with modern retrograde preparations on the background of the mineral fertilizers introduction into the photosynthetic activity of crops and grain yield. The experiments were carried out in 2013 -2017 on the southern black soil in the conditions of the Ukrainian Steppe. On the basis of the study results, it was determined that the introduction of irrigated fertilizer barley in a dose of N30P30 (background) under pre-sowing cultivation and the application of extra-root crop supplements at the phases beginning of the barley outflow straw into the tube and the organoleptic fermentation of Organic D2 and natural microbial complex Escort – Bio creates favorable conditions for the formation at the optimal levels of photosynthetic parameters and grain yield. Thus, on average, over the years of research and by factor variety, grain yield on these experimental variants was 3.37–3.41 t ha-1, which exceeded its level on uncontrolled control by 0.71–0.75 t ha-1 or 26.7–28.2%. Based on the study results, the use of modern regenerating agents against the background of mineral fertilizers can be recommended as an expedient and effective measure of spring barley raising the productivity.

Abstract:

Artificial regulation of the growth and development of cultivated plants aimed to increase biological productivity and improve the quality of eco-friendly products is an important goal of modern agricultural production. Application of the natural growth stimulators and bacterial agents is quite relevant and effective. The field research was conducted on the basis of the research farm ‘Agronomichne’ of Vinnytsia National Agrarian University, village Agronomichne, Vinnytsa district, Vinnytsia region, Ukraine. Features of the growth and development of white lupine (Lupinus albus L.) plants are examined. There has been established a positive effect of the combination of inoculation with the bacterial agent and growth stimulator on the productivity of white lupine, which is important for the formation of high and stable yields. The papers presents the results of studies on the effect of pre-sowing seed treatment and foliar nutrion under conditions of the right-bank Forest-Steppe of Ukraine on the assimilation apparatus of white lupine plants. It has been established that bacterial agents and growth stimulators increase white lupine productivity due to optimization of the studied technological methods of cultivation. The optimal leaf surface area that provided maximum grain yield has been determined. The research has established a positive effect of pre-sowing seed treatment with the bacterial agent Rhizohumin and the growth stimulator Emistym C and foliar nutrition with Emistym C on the chlorophyll content in the white lupine leaves. The influence of the investigated technological methods on the formation of the assimilation surface area and chlorophyll synthesis in the leaves of white lupine has been proved. The preparations studied induce intensive development of the photosynthetic apparatus, yield increase, improvement of the yield structure and they improve grain quality under conditions of right-bank Forest-Steppe of Ukraine. The issue of seed bacterization and application of growth stimulators requires a more detailed study. Therefore, such researches are relevant and significance in terms of both practical and scientific value.

Abstract:

Despite growing interest about field beans (Vicia faba L.), only few researches have been carried out in Baltic countries on the possibility to increase field beans’ yield and quality depending on different agrotechnical measures. Field trial was carried out in 2015, 2016 and 2017. Researched factors during all years were: A – variety (’Laura’, ’Boxer’, ’Isabell’), B – seeding rate (30, 40 and 50 germinate able seeds m-2), C – treatment with fungicide (with and without application of fungicide). Beans’ yield (t ha-1) and yield quality characteristics were detected in the trial. Temperature and moisture conditions were mostly suitable for high yield formation of field beans in all three trial years. In all three trial years, field bean yield has been significantly affected by all factors. The highest yield (p = 0.001) was provided by variety ‘Boxer’ in all years (6.10–7.74 t ha-1). Thousand seed weight (TSW) was significantly affected by variety and fungicide application. From agronomical point of view, crude protein level was not importantly affected by seeding rate changes or fungicide application. Volume weight was affected significantly by increased seeding rate only in 2016. Fungicide application also did not affect volume weight significantly during the whole trial period. Field bean yield increased by each year, but the main tendencies in all years were the same: higher yield and TSW was provided by variety ‘Boxer’, but higher protein content and volume weight – by ‘Isabell’. Seeding rate increase gave positive impact on yield. Fungicide application affected field bean yield, but did not affect its quality significantly.

Abstract:

Pisum sativum L. is important protein crop in the world. The purpose of this investigation was to see whether pea varieties differ in their yield, height and content of protein. Another aim was to select the best varieties suitable for production. Field experiments with different varieties of peas (‘Bruno’, ‘Capella’, ‘Clara’ and ‘Vitra’) were carried out at the Estonian Crop Research Institute in 2014 and in 2015. Yields (t ha-1) in 2014 and 2015 did not differ much, while yield from variety ‘Bruno’ was very different between years 2014 and 2015 and was much higher in 2015. The most suitable height of field peas is in a range of 60…100 cm, because the plants with such a height are most effectively suppressing weeds. It can be concluded that varieties with suitable height in our investigation were: ‘Bruno’, ‘Capella’ and ‘Clara’. Variety ‘Vitra’ was too high, is lodging easily and is therefore hard to harvest. Crude protein content (% in dry matter) was lowest in ‘Clara’; all other varieties had a higher content of protein, within much the same range. Based on the results of present investigation it can be concluded that out of those four varieties the most suitable varieties for production are ‘Bruno’ and ‘Capella’. Choice of the right variety for pea cultivation is very important, but depends on the local agro-climatic conditions. As in Baltic – Nordic countries and in north of America the agro-climatic conditions are more or less similar the results are useful for those countries.

Abstract:

Nowadays, wheat is the most important crop for organic farming systems. However, the varieties bred and tested in the conditions of organic farming systems are still missing, resulting in a very low level of yield in the Czech Republic (less than 50% of level of conventional yield in the same conditions). One reason is that the ideotype of the organically bred variety is different from that of the conventional. The varieties suitable for an organic farming system differ in many respects from those adopted in conventional farming. The first difference is obvious from the conventional tests of the varieties’ value for use, taking only direct indicators influencing the main parameter (yield) into account. Generally speaking, the features to be tested can be divided into 4 groups: the morphological, biological, economic and quality parameters. The conventional varieties are bred in conditions characterised by an abundance of soluble nutrients, and therefore, their root systems are not adapted to an insufficiency or weaker bonding of nutrients. The competitiveness with weeds has also been ignored. Any conventional variety which has not had to confront strong weeds during the breeding process cannot be assumed to be competitive enough in the conditions of an organic agro-ecosystem. Resistance to diseases and pests can be similarly characterised. Varieties are protected by pesticides throughout the conventional breeding process. Because of the seasonal fluctuations in weather, we need a plastic and flexible variety. They also differ in their qualitative parameters.

Abstract:

The effect of different fertilizers on potato tuber yield and its quality was investigated at the Elmininkai Research Station of the Lithuanian Institute of Agriculture during 1997-1999. Potatoes of 10 varieties belonging to different maturity groups were grown on plots with different fertilization. The following potato varieties were investigated: the extra early ‘Venta’ and ‘Ukama’, the early ‘Voke’, the medium early ‘Mirta’ and ‘Karolin’, the medium late ‘Hertha’, ‘Saturna’ and ‘Agria’, and the late ‘Aistes’ and ‘Speci’.
It was established that different fertilizers, varietal properties and meteorological conditions during the potato vegetation period significantly influenced the yield and  quality of different potato varieties. The highest potato tuber yields (20.1–29.6 t ha-1) of all the tested varieties were harvested when one-component and complex mineral fertilizers with microelements had been applied, the lowest (14.6–21.7 t ha-1) when manure (60 t ha-1) had been used in spring. The highest starch and dry matter content had potatoes of the following varieties: the early ‘Voke’ (up to 16.3% and 22.6%, respectively), the medium early ‘Karolin’ (up to 15.6% and 21.8%, respectively), the medium late ‘Saturna’ (up to 17.4% and 23.7%, respectively) and the late ‘Speci’ (up to 16.3% and 22.6%, respectively). The 1998 vegetation period was the most favourable for potato tuber yield, and the 1997 vegetation period for the accumulation of starch and dry matter. The vegetation period of 1999 was the most unfavourable both for potato tuber yield and the accumulation of starch and dry matter.
