In rats exposed to cold over a 5-week period there occurs a rise and then a partial return to initial values of the fat-free dry matter content of epididymal adipose tissue. The fat-free dry matter is also slightly higher in the right fat pad. Under such circumstances there may be some advantage in expressing metabolic activity in terms of fat-free dry matter rather than on a wet weight basis. Both methods are equally satisfactory in control rats.

The article presents the results of studies of the effect of seeding rates and row spacing on the forage productivity of different alfalfa ecotypes when mowing grass in the flowering stage. In the soil-climatic conditions of the right bank forest-steppe irrespective of the effect of abiotic and biotic factors during the growing season, high adaptability of alfalfa of the southern ecotype of the Angelica variety was established, which formed a stable crop of green mass at the optimal seeding rate (8,0 million/ha) and width 12,5 cm. For an average of two years of grass use, the varieties of alfalfa Rosana and Angelica provided a yield of green mass of 62,96-64,02 t/ha, which was 11,1-14,9% higher than for sowing with the norm of sowing 4,0 million/ha, and 6,3-7,1% with row spacing half (25,0 cm). It was found that in two years of use of alfalfa Angelica variety had higher dry matter content, compared with the variety of Rosana and were respectively 23,05 and 22,98%. There was a gradual decrease in the dry matter content with a thickening of the herbage in the Rosana variety from 23,32 to 22,72% and from the Angelica variety from 23,31 to 22,84%. As the row spacing increased from 12,5 to 25,0 cm, the solids content increased by 0,28-0,62%, or 22,74-22,84 and 23,12-23,36%. The crude protein content in the dry matter of alfalfa plants of both varieties differed by slopes and years of herb use. The highest content of crude protein was obtained in the dry matter for sowing with a row spacing of 12,5 cm, which averaged 21,10% in the Rosana variety and 20,23% in the Angelica variety or increased by 0,79-0,87%, compared to the row spacing of 25,0 cm. Thus, irrespective of the hydrothermal conditions during the growing season of the studied varieties of alfalfa sowing Rosana and Angelika, the average yield of dry matter at the level of 13,64-13,93 and 2,76-2,88 t/ha of crude protein at the width of row 12,5 cm. Key words: alfalfa, variety, flowering start, crude protein, dry matter, yield, green mass.

The Difference

Relevance. Garlic is one of the most valuable food products and the increase in its production is associated with the growing needs of the population, the processing industry and medicine. Garlic is very responsive to the use of fertilizers, which are an integral part of the cultivation of individual crops and are aimed at obtaining high and stable yields with good quality products.Methods. The purpose of the research is to study the productivity of winter garlic, depending on the application of various norms of fertilizers. The studies were conducted in the arid zone of the Stavropol Territory. The objects of research were varieties of winter garlic Lyubasha, Leader, Jubileyny Gribovsky, the rate of mineral fertilizers. Potassium nitrate, monopotassium phosphate, ammonium nitrate, ammophos were used as mineral fertilizers.Results. As a result, it was established that with the use of fertilizers, the quantitative and qualitative indicators of the formation of the yield of garlic increased. The largest vegetative mass of garlic was formed when using the N120P95K50 in the food system; the highest values for plant height and leaf area were obtained, the difference with respect to control, was between 5-18 cm and 9-45 cm2 , respectively. The largest mass of the bulbs was obtained when making garlic N120P95K50 – 51-85 g, which exceeded the control by 15-18 g. Garlic plants grown with the use of N80P95K50 were the least affected with diseases - the degree of development of the diseases was less than with control, by 0.2-1.5%. The use of fertilizers in the cultivation of garlic contributed to an increase in crop yield: the highest indicators were obtained when applying N120P95K50 – 19.4-21.3 t/ha, which was more control, by 0.4-3.2 t/ha. Most of the nutrients in the bulbs accumulated when using N80P95K50: the dry matter content exceeded the control, N80P95K75 and N120P95K50 by 3-10%, sugars – by 0.3-1.4%, essential oils – by 0.02-0.1 mg/100 g, vitamin C – 2-8 mg per 100 g wet weight. The amount of nitrates in garlic bulbs was lower than the MPC by 3-33 mg/kg.

A 3-year experiment was conducted in central Hungary comparing the effect of an irrigation treatment on content and yield of dry matter, storage carbohydrates, vitamin C, total flavonols, and total polyphenols of onion (Allium cepa L.) grown from sets. Rain-fed plots were set as controls. Conditions during the first 40 days of the growing season had a decisive effect on yield and bulb size; warmer and dryer weather during this period resulted in lower yield. Colder and wetter weather conditions resulted in higher bulb yield, but also decreased accumulation of secondary metabolites. Dry matter content values ranged between 12% and 14% and were not influenced by the water supply. Storage carbohydrate-to-dry matter ratio was not changed by the water supply. Total flavonol contents (sum of the concentrations of nine individual flavonols) varied between 430 and 753 mg·kg−1 on a fresh weight basis. Total polyphenol values ranged between 607 and 1029 mg·kg−1 on a fresh weight basis. A statistically significant correlation was found between flavonol content and polyphenol content for the rain-fed treatment, but this was not the case for the irrigation treatment. Irrigation significantly increased total flavonol and total polyphenol concentrations during the dry years. Irrigation significantly increased the bulb yield by 33% to 160%, depending on the year. Consequently, by applying irrigation, yields of nutritive compounds became 1.5 to two times higher.

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.
