USE OF MINERAL SUBSTANCES BY MILK COWS IN THE SUMMER PASTURE PERIOD

Posted in 2019, AGRICULTURE, Issue № 6(84) June 2019 | 0 comments

The article is devoted to the study of the efficiency of metabolism and the use of certain vital macro- and microelements in the body of ruminants in the pasture period. The research and production experiment was conducted at the experimental site of the FSBSI ARRIRL located four kilometers south-east of the city of Tver on two groups of cows – analogues of black-and-white breed with average daily milk yield of 12-15 kg of milk in the eighth month of lactation to identify the provision of dairy cows with mineral elements at different levels of feeding them with concentrates. The possibility of reducing the proportion of concentrated feed in the diets of cows from the experimental group was studied as a result of research, which contributed to an increase in the consumption of pasture grass throughout summer months. During the season, animals from the experimental group consumed herbs by 19.6% more than the control group. Relative absorption of mineral substances in experimental animals in the studied rations was at a sufficiently high level. It was concluded that with good herbage the reduction of concentrate consumption from 240 g to 130 g per 1 kg of milk in summer rations of cows with productivity in the control group comprised 12.2, and in the experimental group – 12.6 kg per day, with fat content in milk – 4.12% and 4.46% respectively, and does not affect the digestibility of minerals. The content of chemical elements in the feces, urine, and milk and in the body of animals depends on their content in the diet. When keeping cows with milk yield of 12-15 kg of milk on cultivated pastures, it is advisable to feed no more than 130-150 g of concentrate per 1 kg of milk while simultaneously controlling the ration for mineral elements, especially phosphorus, cobalt, iodine, etc.

Posted in 2019, AGRICULTURE, Issue № 6(84) June 2019 | 0 comments

На протяжении 2015-2018 гг. на полигоне ФГБНУ ВНИИМЗ были проведены исследования перспективных сортов козлятника восточного и интенсивных видов злаковых трав. К исследуемым сортам козлятника восточного (Galega orientalis) относятся: сорт Гале селекции Эстонского НИИ земледелия и мелиорации, Юбиляр и Кривич – ГНУ Псковский НИИСХ. Злаковый компонент состоит из следующих видов трав: кострец безостый (Bromopsis inermis) сорта Вегур, тимофеевка луговая (Phleum pretense) сорта ВИК 9, двукисточник тростниковый (Phalaris arundinacea) сорта Урал. Наибольшая густота стеблестоя козлятника восточного отмечена в чистом посеве сорта Кривич и составила по годам опыта 53-144 шт./м2. В среднем за годы исследований агроценозы на основе козлятника восточного формируют густоту стеблестоя от 36 шт./м2, в смеси со злаками до 136 шт./м2. Посевы козлятника восточного в смеси со злаками способны обеспечивать стабильное долголетие и менее засоряемы несеянными видами трав. В условиях Нечерноземной зоны Верхневольжья агроценозы на основе козлятника восточного обеспечивают высокую продуктивность до 11,7 т/га сухой массы. Ботанический состав травостоев и конкурентоспособность трав по годам опыта изменялись. По мере увеличения возраста агроценозов происходит постепенное увеличение доли козлятника восточного. В начале исследований наибольший процент у злаковых трав в бобово-злаковых травостоях отмечен у двукисточника тростникового. К 2018 году среди злакового компонента преобладала тимофеевка луговая. Фитоценотическая активность козлятника восточного постепенно возрастает к 2018 году, составив 0,5-1,2. Индекс ценотической активности злаковых трав по годам опыта составил у костреца безостого 0,5-1,8, двукисточника тростникового 0,6-2,6, тимофеевки луговой 0,7-2,7.

INFLUENCE OF MULTIPLE-PURPOSE COMPOSITION COMPOST ON AGROPHYSICAL PROPERTIES OF SOIL IN DRAINED CULTIVATED LAND

Posted in 2019, AGRICULTURE, Issue № 5(83) May 2019 | 0 comments

The paper presents the data of long-term monitoring of the physical properties of soils within a variety of landscapes and under conditions of a different agricultural background, conducted at the agroecological testing ground of the FSBI ARSRIRL. The effect of multipurpose compost on the change in the basic agrophysical properties (density and humidity) of sod-podzolic soil within a finite morainal hill was shown. Soils under crops of grain-grass crop rotation were studied on a test field where 12 t/ha of multi-purpose compost were introduced and on a control field where fertilizers were not applied. The obtained data were processed by the variance analysis method. In the course of the research, it was revealed that the use of products of bioconversion of organic raw materials contributed to the decrease in the density of the arable layer of soil under grain crops by 1.60-5.04%. Under grasses, a decrease in soil density was observed only within the northern slope (by 0.86–3.38%). The spatial variability of soil moisture was significantly influenced by the structure of the soil cover, soil density, and the agricultural landscape structure of the territory. However, the character of the cultivated crops had the greatest impact on it. Under perennial grasses, soil moisture increased by 27.3-31.3% compared with cereals. The dependence of soil moisture on the use of multi-purpose compost has not been established. However, there is a tendency to decrease it in the lower part of the southern slope and at the top of the hill. The revealed patterns make it possible to develop measures for regulating the water-physical properties of the soil in the agricultural landscape and, thereby, to improve soil fertility and the environmental sustainability of the natural environment.

FOREST, DROUGHT, GRAIN CROP AND DENDROCHRONOLOGY

Posted in 2019, AGRICULTURE, Issue №3(81) March 2019, Issue №3(81) March 2019 | 0 comments

Drought is a meteorological phenomenon that had and continues to have a tremendous impact on the life of human society. This phenomenon is divided into a complex of appearances, for example, soil and atmospheric drought, winter drought, etc. The drought during different periods of the growing season has a physiologically different effect. Physiologically significant drought is difficult to describe in quantitative characteristics of meteorological parameters since the effects of the interaction of environmental factors in an ecosystem can change the response of a plant to a clearly defined, limited set of meteorological parameters. Features of the processes of photosynthesis and transpiration determine that the function simulating the variability of growth rings from year to year, always and under any conditions will contain a drought-dependent variable. Dendroclimatic studies can be directed either to the separation of the drought-dependent climate signal from the chronology, or, conversely, to the search for chronologies with a “clean” easily readable drought-dependent signal. Due to its retrospective capabilities, dendroclimatic studies are promising for the study of droughts, including droughts affecting crop yields. Studies of this kind in the future can provide information for predicting the grain yield.
