Effect of the production technology of vine mother plants on their ability to vegetative propagation
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45For many years, grapes were considered to be an unpromising crop in the conditions of the Central Non-Black Earth Zone but their wider spread has been encouraged by the appearance of new varieties whose berries ripen in a relatively short time. The assortment of modern grape varieties for amateur cultivation in the non-Black Earth Zone consists mainly of interspecific hybrids based on Vitis amurensis Rupr., Vitis riparia Michx., Vitis labrusca L., Vitis berlandieri Planch., which causes problems with their vegetative propagation.
Yield and phytosanitary state of the last crops of the crop rotation of wheat and barley
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45The article shows the analysis of the effect of long-term application (since 2006) of nonmoldboard and combined systems of main tillage in a crop rotation in comparison with annual moldboard tillage on productivity of spring wheat, yield and phytosanitary state of barley. The author studied tillage options in a cereal-grass rotation (71% cereals) with different types of fallow (clean, manured, clover and mustard) and with winter rye straw left in the field. Annual mouldboard tillage resulted in the highest yields of spring wheat and barley in the experiment - 2.90 and 2.31 t/ha.
Chinese cabbage clubroot resistance genotyping and evaluation of combining ability
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45Chinese cabbage is a multivitamin vegetable crop and it is in constant demand due to its taste and dietary qualities, as well as the ability to harvest this crop twice a year due to the short growing season. There are less than 70 cultivars and hybrids in the State Register of Russia, many of them are susceptible to clubroot caused by soil pathogen P.brassicae Wor. In Russia, consumer demand needs to be met with new competitive hybrids that are resistant to major diseases such as clubroot.
F development of the physiological and biochemical status of the blood of the Saanen goat breed kids with age
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45However, when rearing replacement young animals, specialists are faced with factors that directly and indirectly affect the harmonious development and high productivity potential of animals of this breed. To develop evidence-based measures for growing, feeding, keeping and treating animals, it is necessary to know the characteristics of the individual development of their organism, to reveal the mechanisms of the development of the physiological, biochemical and immunological status in ontogenesis, in particular in postnatal ontogenesis.
Oil yield of rapeseed plant – botanical nature, biochemical features and nutritional potential
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45The annual rapeseed (Brassica napus L.), a member of the Brassicaceae family, has long been used as a source of technical oil. The development of low-erucic varieties (canola, less than 5% erucic acid) by Canadian breeders in the 1970s made rapeseed a valuable and promising oilseed crop.
Field assessment of the result of biological treatment of seeds of spring soft wheat (Triticum aestivum L.)
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45The effect of pre-sowing biological treatment of seeds of two varieties (Tyumenskaya 25 and Shortandinskaya 95 improved) of spring soft wheat on field germination of seeds, biological stability and plant survival during the growing season in relation to the productivity was studied. The study was conducted in field conditions (an experimental plot of the biostation “Lake Kuchak”of University of Tyumen) on sod-podzolic soil, sandy loam in granulometric composition.
Correlation of chest parameters with morphometry of the body and internal organs in female Hedlund minks (h/h), Pastel (b/b), Scanblack (N/N, N/n)
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45The study of morphometric features of the body and the establishment of relationships between them is the basis for the selection of American minks (Neovison vison). In this regard, the study of body parameters and identifying correlations with significant selection indicators are of practical importance. At the same time, such a morphological indicator as chest girth has not practically been studied.
Fortification of dairy products with pro- and prebiotics
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45The composition of the microflora in the human gastrointestinal tract (GI tract) can change constantly. It depends on the conditions in which a person was born, age, diet, lifestyle, region of residence, various diseases and medications taken. It is very important to maintain the correct balance (ratio) of microorganisms in the GI tract. The novelty of the research lies in the development of symbiotic fermented dairy products, including probiotic microbial cultures and prebiotics.
Effect of mineral nutrition on yield and grain quality of winter wheat cultivated in the Ferghana valley
Submitted by Гость (not verified) on Tue, 07/09/2024 - 16:45Winter wheat in pure fallow is in great need of phosphorus fertilizers on light gray earth soils. The content of N, P and K in leaves in the heading phase and the ratio of N: P and N: K correctly reflects its nutrient requirements. The optimal doses for the yields do not ensure that the grain is of high quality.
