Abstract Germination and sugar beet yield after seed stimulation were investigated. The seeds came from the energ'hill technology and were subject to laser irradiation. The experiments were conducted in the laboratory and field conditions. Lengthening of germinal roots and hypocotyls was observed. A positive effect of the stimulation on the morphological features was observed for the Eh seeds and laser irradiation applied in a three-fold dose. The energ'hill seeds exhibited a significantly higher content of carotenoids in seedlings and an increase in the content of chlorophylls. Laser light irradiation favourably modified the ratio of chlorophyll a to b. The leaves and roots of plants developed from the energ'hill and irradiated seeds were characterized by higher dry matter content thanin non-stimulated seeds. Seed stimulation had a positive influence on yielding and the saccharose content.

The object of an experiment was inorganic and organic forms of zinc, copper and manganese applied in mineral mixtures to dairy cows. The experiment was carried out on 90 cows with average milk yield for previous lactation of about 9 500 kg milk. The cows received mineral mixtures containing inorganic or organic forms of zinc, copper and manganese for 6 weeks before calving and during the first three months of lactation. The application of microelements as bioplexes in amounts covering 30% of daily requirements of cows had a positive effect on an increase in colostrum dry matter content from 20.9 to 23.35% as well as on the concentration of protein and fat, and the level of minerals – calcium, phosphorus, magnesium, zinc and copper. In cows’ milk in the 2<sup>nd</sup> and 3<sup>rd</sup> month of lactation there were no differences in contents of minerals. However in the blood serum of cows in the 1<sup>st</sup> and 2<sup>nd</sup> month of lactation an increase in calcium concentration from 1.96 to 2.14 g/kg was observed while the content of phosphorus also increased average from 1.76 to 2.22 g/kg in the first trimester of lactation.

Buffer feeding is a widely used strategy to improve DM intakes from dairy cows at grass. A very wide range of products have been used as buffer feeds resulting in a wide range of responses. Less well understood are which factors are important in explaining these responses. In this experiment the buffer feed characteristic “dry matter content” and the animal factor “stage of lactation” were used as variables in order to gain a better understanding of responses to buffer feeding.Forty Friesian cows, of which 20 were spring calving and 20 autumn calving were used in a continuous design experiment lasting 5 weeks from 3 May until 7 June 1993. The animals were allocated to four treatments on basis of milk yield, liveweight and stage of lactation. The treatments were grazing only (C), grazing and a buffer feed at 30% DM (B30), 50% DM (B50) and 80% DM (B80) and for each treatment half the cows were spring calving (S) or autumn calving (A). The grazing consisted of a 8 ha field of predominantly perennial ryegrass which was split into 4 equal paddocks which were grazed on a daily rotational basis.

The study concerned an evergreen herbal plant <i>Waldsteinia trifolia</i> Roch. This species can be found more and more often in garden plantings in Poland. The aim of the study was to estimate the content of photosynthetic pigments, anthocyanins and dry matter as well as the permeability of cytoplasmatic membranes of <i>Waldsteinia</i> leaves. Plants grew in an ornamental plant collection at the premises of the Faculty of Horticulture of the Agricultural University in Kraków. The study was conducted in 2006 and 2007 in the following months: March, May, June, September, October and November. The permeability of cytoplasmatic membranes was estimated based on electrolyte leakage from leaf discs at 20°C in relation to total electrolytes in the tissue after unfreezing. The first days with temperature drops down to around 0°C in autumn resulted in a decrease in chlorophyll a, b and carotenoid content, but significantly increased anthocyanin content. The ratio of chlorophyll a to b and the ratio of total chlorophylls to carotenoids did not change in particular months. In both years of study, similar changes in dry matter content of the <i>Waldsteinia</i> leaves were observed. Dry matter content significantly increased in June and November and decreased in May and October. In June and in autumn, after first slight frosts, an increase of electrolyte leakage from the leaf discs was observed. However, high dry matter content (40.3%) was accompanied by lower permeability of the cytoplasmatic membranes of the leaves after winter during March. These results have shown good adaptation of <i>Waldsteinia trifolia</i> plants to the climatic conditions in Poland.

The article is devoted to the study of the effect of foliar treatment of Tomatillo plants with the use of drugs of bacterial origin. The paper scientifically substantiates the influence of biologicals on the morphological and biometric parameters of the plant. It was investigated that the emergence of seedlings in varieties Lichtaryk and Pineapple was observed for 7-8 days. After diving and two treatments of plants with drugs, their positive effect on the growth and development of Tomatillo, especially in the phase of budding, flowering and fruiting. A short period of bud formation on the plant was characterized by a variety of Tomatillo Lantern from the use of Biomag. Thus, the beginning of the formation of buds occurred on 66 days on the Lantern variety. A similar effect of the biological product was found during the flowering phase and fruit set. As a result of the activity of Azotobacter chorococum bacteria, the growth and development phases of the Lantern variety are accelerated by 1-3 days compared to the control variant. The use of biological products has had a positive effect on the biometric parameters of the plant. When using bacteria p. Saccharomyces, Azotobacter chroococcum, Paenibacillus polymyxa, Enterobacter nimipressuralis, plant height and stem diameter depended on the type of biological product used. The height of the plant ranged from 82,8 cm to 89,6 cm in the variety Lantern and from 86,8 cm to 91,3 cm in the variety Pineapple. As a result of spraying the plants with Azotobacterin or Rostmoment, the height of the Tomatillo plant exceeded the height of the plant of the variant where biological products were not used. In these variants, the excess of plant height relative to the control was 8,2% for the variety Lantern and 4,3 % for the variety Pineapple, respectively. The diameter of the stem was in the range of 1,9-2,0 cm. Due to the activity of the bacteria Azotobacter chroococcum, Paenibacillus polymyxa, Enterobacter nimipressuralis or yeast p. Saccharomyces and products of their metabolism, revealed a positive effect of biologicals on the increase in leaf area and dry matter content of the leaf. As a result of cultivation of the cultivar Lichtarik and application of Rostmoment or Biopolitsid the area of leaves was at the level of 79,5 thousand м2/ha and 77,6 thousand м2/ha. Growth moment, for the cultivation of the variety Lantern, helped to increase the dry matter content of the leaf by 16,4 %. Treatment of Lantern plants with liquid humus-based concentrate Humisol provided the highest weight of Tomatillo fruit, which was at the level of 8,4 g, and the use of Humisol or Rostmoment for growing varieties Lantern and Pineapple increases the diameter of Tomatillo fruit by 6,9-10,3 %. Humisol, due to humic and fulvic acids, natural phytohormones affects the growth processes of the plant more intensively, which provided in the formation of the largest mass of fruits and their diameter. High yield is characterized by the Tomatillo variety Lantern with five applications of Humisol or Biopolicide, where its value is 33,3 t/ha and 32,0 t/ha. Key words: morphological features, biometric indicators, tomatillo, fruit yield, marketability.

Relevance. The creation of heterotic hybrids of watermelon is one of the modern breeding trends for solving the problem of providing the population of the Russian Federation with melon production. The process of creating heterosis hybrids can be accelerated by the assessment of the total combination ability (ОCS) of parental lines.Materials and methods. The studies were carried out in the zone of the Volgograd Trans-Volga region at the Bykovskaya melon selection experimental station, in dry conditions in 2018 and 2019. The object of research was 9 paternal lines and 3 maternal lines of watermelon. The assessment of the general combining ability was carried out according to two indicators: yield and dry matter content.Results. In the course of the research, the obtained F1 watermelon hybrids were assessed for a set of economic characteristics in comparison with the standards: Zenit, Sinchevsky and Barkhan. Based on the results of the work, F1 hybrids were identified according to the length of the growing season, yield, and dry matter content. By selecting valuable genetic sources with a high GCS, it is possible to successfully conduct breeding to improve the economically valuable indicators of F1 watermelon hybrids. According to the results of studies on yield, both in 2018 and in 2019, heterotic hybrids were distinguished, obtained from crossing with the paternal lines Favorit, Stimul, Ikar, the average effect over two years ranged from 3.5-10.6 t/ha. Among the studied maternal lines, the line Chms-4 has a positive effect, the average effect was 1.2 t/ha. In terms of dry matter content, a positive effect was found in the paternal lines Stimul – 1.8%, Medunok – 1.6%, Favorit – 0.8%, and in the maternal line Chms – 41.8%Conclusions. Based on the results of the analysis of the combining ability in terms of yield and dry matter content, we identified two promising paternal lines for creating heterotic watermelon hybrids: Favorite, Stimul. Also, one maternal line Chms-4 was distinguished. When using these lines in heterotic breeding of watermelon, in most crossing combinations, heterosis will be manifested in one or two characters.

In 2013 and 2014, field experiments involving winter wheat were conducted at Aleksandras Stulginskis University’s Experimental Station on a medium-textured Cal(ca)ri-Epihypogleyic Luvisol. N150P90K120 were applied as the main fertilizers. Additionally, a foliar fertilizer including amide nitrogen, sulphur and magnesium (MgO concentrations ranging from 0.25 % to 2.5 %), (further referred to as magnesium fertilizer), was sprayed at the tillering and booting stages of winter wheat. It was found that magnesium fertilizer foliar-applied at the end of tillering and booting stages tended to increase chlorophyll a and b contents in winter wheat leaves. Chlorophyll a content in leaves significantly increased when the solution with 2.5 % concentration of magnesium had been applied at tillering and when 0.5, 1.0 and 2.5 % concentrations of the solution had been applied at booting stages. Chlorophyll b content in winter wheat leaves was significantly affected by the solutions with 0.5, 1.0 and 2.5 % magnesium concentrations at tillering and by the solutions with 0.5, 1.0, 1.5, 2.0 and 2.5 % magnesium concentrations at booting stages. The highest increase in dry matter content was recorded when 2.5 % MgO solution had been applied at booting stage. A statistically significant correlation was established between the MgO concentrations applied at tillering (r = 0.905*) and booting (r = 0.863*) stages and nitrogen content in winter wheat dry matter.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.

Цель исследований – дать оценку сохраняемости и болезнеустойчивости современных сортов и гибридов моркови столовой и определить корреляционные зависимости влияния биохимических показателей качества на сохраняемость и степень поражения моркови столовой различными видами болезней в процессе хранения. Исследования проводились в 2011–2016 годах во ВНИИО – филиале ФГБНУ ФНЦО по общепринятым методикам. В биохимической лаборатории отдела земледелия и агрохимии содержание сухого вещества определяли высушиванием до абсолютно сухого веса, общего сахара – по Бертрану, аскорбиновой кислоты – по Мурри, нитраты – ионоселективным методом. При характеристике моркови столовой важнейший показатель, определяющий его качество – количество сухого вещества и сахаров. В процессе хранения были выявлены следующие болезни моркови: серая гниль (Botrytis cinerea Pers. ex Fr.), белая гниль (Sclerotinia sclerotiorum (Lib.)), белая парша (Rhizoctonia carotae Rad.), альтернариоз (Alternaria radicina M., Dr. et E.). В большей степени сортообразцы моркови столовой поражались серой гнилью. Лучшими по сохраняемости сортообразцами были Корсар (94,6%), F1Берлин (94,5%), Берликум Роял (94,1%) и F1 Звезда (94%). Сохраняемость у зарубежных сортов и гибридов моркови столовой была немного выше, чем у отечественных (на 0,4%) как за счет меньшей величины убыли массы (6,3% против 6,4%), так и потерь от болезней (1,6% против 1,9%). Сохраняемость корнеплодов моркови находится в прямой корреляционной зависимости от содержания сухого вещества (r=+0,41), каротиноидов (r=+0,39), моносахаров (r­=+0,30) и суммы сахаров (r=+0,27). Проявление серой гнили находится в обратной корреляционной связи с содержанием сухого вещества и каротиноидов (r=-0,37 и r=-0,35 соответственно), белой парши – в прямой корреляции с содержанием сухого вещества , моносахаров и дисахаров (r= +0,21; r= +0,39; r= -0,41 соответственно), белой гнили в обратной корреляционной связи с содержанием сухого вещества, моносахаров и дисахаров. The purpose of the research is to assess the persistence and disease resistance of modern varieties and hybrids of carrots and to determine the correlation between the influence of biochemical quality indicators on the persistence and degree of damage to carrots by various types of diseases during storage. The research was conducted in 2011–2016 at ARRIVG – branch of FSBSI FSVC, according to generally accepted methods. In the biochemical laboratory of the Department of Agriculture and Agrochemistry, the dry matter content was determined by drying to absolutely dry weight, total sugar – by Bertran, ascorbic acid – by Murri, nitrates – by the ion-selective method. When describing carrots, the most important indicator that determines its quality is the amount of dry matter and sugars. During storage, the following diseases of carrots were detected: gray rot (Botrytis cinerea Pers. ex Fr.), white rot (Sclerotinia sclerotiorum (Lib.), white scab (Rhizoctonia carotae Rad.), alternariasis (Alternaria radicina M., Dr. et E.). To a greater extent, varieties of table carrots were affected by gray rot. The best preserved varieties were Corsar (94.6%), F1 Berlin (94.5%), Berlicum Royal (94.1%) and F1 Zvezda (94%). The persistence of foreign varieties and hybrids of table carrots was slightly higher than that of domestic ones by 0.4%. both due to a smaller amount of weight loss (6.3% vs. 6.4%) and losses from diseases (1.6% vs. 1.9%). The persistence of carrot root crops is directly correlated with the content of dry matter (r=+0.41), carotenoids (r=+0.39), monosaccharides (r=+0.30) and the amount of sugars (r=+0.27). The manifestation of gray rot is in inverse correlation with the content of dry matter and carotenoids (r=-0.37 and r=-0.35, respectively), white scab is in direct correlation with the content of dry matter (r= +0.21; r= +0.39; r= –0.41, respectively), white rot is in inverse correlation with the content of dry matter, monosaccharides and disaccharides.
