The effect of the level of milk production of firstcalf heifers on the further productivity, reproductive function and duration of economic exploitation of holstein cows in southern Russia
The article presents the results of the studies of the effects of low-frequency electromagnetic field on starter cultures. It suggests a possibility of using electromagnetic technology in smoked sausages
In the soils of rice fields, eluvial gley processes
develop, which are manifested in redistribution of silty
particles along the profile, water-soluble humus,
mobile compounds of iron and phosphorus. Most
intensively, these processes are developed in meadowbog
soils, confined to closed depressions of the plains
plain. Meadow-black soils lying on elevated relief
elements have more favorable physical, physicochemical
and oxidation-reduction properties for
cultivating rice and accompanying crops in crop
rotation. The highest yield of rice is formed on high
checks and higher at 12,4 c/ha than on low ones
The article presents the results of studying the influence of the method of treatment before storage and storage parameters, including the relative air humidity, on the value of general losses of carrots. The taproots treatment before putting into storage was carried out with electromagnetic fields of extremely low frequency and the bio-preparation Vitaplan. After treatment, the taproots were kept at a temperature of +2±1°С for 56 days and +25±1°С for 21 days. In the process, the relative air humidity was changed from 40 to 90%. At a storage temperature of +2±1°C, the lowest total loss was observed at a relative humidity of 90%. At a storage temperature of +25±1°С, the optimal, from the point of view of decreasing the general losses, turned out to be the relative air humidity of 70%: with decreasing relative air humidity to 40%, significant increase of natural losses was observed, because the taproots were losing water intensively, and with increasing relative air humidity to 90%, favorable conditions were created for the growth of pathogenic microflora, which caused significant losses from the microbiological decay. The method of pretreatment of carrot taproots, providing the lowest general loss during storage in all the studied conditions, was joint treatment with ELF EMF and the bio-preparation called Vitaplan
In the article we have presented the results of research of influence of activated mineral fillers on mechanical properties of fine-grained concrete. It is shown that clay and zeolites in mechanical activated condition have increased both early and estimated durability of concrete
The influence is shown for the race of yeasts to the dynamics of the fermentation of grape must, the composition of organic acids and aromatic of components. The races, which ensure obtaining high-quality winemakings material are presented
The article brings the results of three-year studies of the
influence of the periods of sowing on productivity of
new varieties and lines of winter barley
The article presents the results of the studies on the
effect of the processing of grape variety Saperavi with
a growth regulator called Vimpel with water soluble
and foliar fertilizers of new generation - Nutrivant plus
and Kelik potassium silicon, both in pure form and in
a tank mixture. Processing of bushes was performed
three times: after flowering, growth phase of berries
(berry of a pea), the beginning of ripening berries. We
used Vimpel drug and foliar fertilizers such as
Nutrivant plus and Kelik potassium-silicon, both in
pure form and in conjunction with Vimpel; it led to a
significant increase in weight of the bunch, bush crop
and planting yields. The smallest yield increase was
provided by Vimpel. However, the combined use of
this drug on a background of Kelik silicon- potassium
foliar fertilizer and Nutrivant plus led to a greater
increase in yield from the bush than when used
fertilizers only. Processing of bushes by Vimpel in
combination with a foliar application of Kelik
potassium-silicon not only led to a significant increase
in crop yields from the bush and plantations, but in
two cases of the three it contributed to a significant
increase of the mass concentration of sugars in the
juice of berries. Using Vimpel, together with Nutrivant
plus foliar application for two years out of three
promoted maximize yields (23.4 and 18.4%) with a
decrease in sugar content, and in one year - an increase
in the harvest of 10.4%, with a significant increase in
mass sugar concentration (1.92 g / 100 cm3 or 9.2%).
Thus, the processing of Saperavi grapes with a growth
regulator called Vimpel and water soluble foliar
fertilizers of new generation - Nutrivant plus and
Kelik potassium and silicon is an effective method of
increasing the yield and quality of Saperavi grapes
In the leached black soils of the foothill zone of the
Kabardino-Balkarian Republic on the territory of
training experimental plant of FSBEI HE
Kabardino-Balkarian state agricultural university
named after V.M. Kokova we have studied the
effect of soil and climatic conditions of area of
cultivation and application of micro – macro
fertilizers, plant growth regulators and biological
products on the crops of lentils, their impact on the
efficiency and quality. It is proved that in general,
the natural conditions of the foothill zone are
favorable for cultivation and obtaining high yields
of major crops. The analysis of meteorological
conditions of the area (typical for the whole area)
shows that there are great reserves and
opportunities to obtain high and stable yields of
lentils grains. These morphological, genetic and
agrochemical parameters of leached chernozem
growing zones suggest the soil favorable to the
growth and development of lentils. On average,
during the years of studies, the number of plants on
which we had marked tubercles, on the example of
Rauza varieties in the background variant, was
63.7%; the use of the drug called Agropon C in
combination with sodium selenite increased by
15.2% the number of plants with root nodules.
Increasing the number of plants with root nodules
was accompanied with increasing the number and
weight of nodules per plant by 8.1 pc. and 10.1 mg.
respectively. The highest yield - 2.66 t/ha under
experimental conditions was obtained in the form
of joint use of the drug Agropon C and sodium
selenite with a seeding rate of 2.2 million viable
seeds per hectare, which is higher than the
reference version for this seeding rate by 0.46 t/ha
or 17.3%. The maximum value indicators of protein content in the seeds and collecting the
protein per unit area reached with the use of joint
application of Agropon C and sodium selenite,
where we achieved the seeding rate of 2.2 million
of germinating seeds per hectare and made up
29.6% and 787 kg/ha, respectively
