In the conditions of the Krasnodar region, we consider
the quantitative and qualitative characteristics of seeds
obtained when using different schemes of organization
of hybrid seed production of squash in the Krasnodar
region. As a result of studying various techniques in the
production of hybrid seed of summer squash, we have
established the effectiveness of using open pollination,
and assessed the approbation of the signs of F1 hybrid
plants obtained under different schemes of organization
of hybrid seed production of squash
The purpose of the research is to compare the effect
of a new symbiotic feed supplement created based
on propionic and lactic acid bacteria with a widely
used domestic and foreign enzyme-probiotic
preparations in chickens 0-28 days of age of the
Lohmann Brown egg cross. In the experiment, there
were six groups of chickens: group 1 received basal
diet (BD); group 2 – BD + symbiotic preparation;
group 3 – BD + Bacell; group 4 – BD + Agrocell;
group 5 – BD + Agroksil; group 6 – BD + Ollzaym
Vegpro. Average daily gain, food conversion rate
per 1g of weight gain, digestibility of organic matter,
crude protein, crude fiber, crude fat, made up
respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0,
81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1;
group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4
– 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50,
1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92,
73.2, 67.5, 70.7, 94.3. The growth rate of chickens
fed with symbiotic feed supplement was 2.3%
higher than in the control and they showed the
highest fiber digestibility. The chickens on diet with
Agroksil enzyme efficiently raised growth rate
(+4%) and reduced feed costs (-4.2%). Agrocell
increased weight gain by 2% and reduce feed costs
by 2.6%. The growth rate of chickens fed Ollazaym
Vegpro was the lowest (96.8% of control), despite
the fact that it increased significantly the
digestibility of crude protein, but slightly improved
the digestibility of other nutrients. Outcome:
symbiotic feed supplement may be of interest as a
means of increasing the productivity of chickens
The article presents materials on comparative study of the nutritional value of chickpeas and peas which are widespread in the arid zone of the Southern Urals. The scheme of the scientific and economic experiments involved the assessment of yield formation of chickpeas and peas during the vegetation. The study showed that different varieties of chickpea and pea have considerable difference in the content of nutrients. The amount of crude protein in the pea grain ranged from 25.1 to 26.8%, and chickpea – 21.7 - 22.9%. With regard to the fat, its highest concentration was in chickpea grain - 3.63%, on average, which is 1.16% higher than on average in the pea grain. The chemical composition of the pea and chickpea grain of different varieties points to differences in their composition and homogeneity within the culture. Basing on the study, we recommend to sow chickpea and pea grain in the middle of May to obtain the highest yield, this, in turn, has a positive effect on the nutritional value of the crops. When selecting plants for cultivation in the conditions of the Southern Urals, it is preferable to choose the variety of Madonna pea, which has a higher potential for yield than the chickpea variety Krasnokutsky-123. It has been experimentally found that chickpea grain has better moisture-retaining power in a bound condition during the vegetation period as compared to the relevant characteristics of pea grain, which is a positive drought-resistant value of crop. In structural elements of the harvest the peas showed the trend of the highest rates in comparison with the corresponding elements in chickpeas
The article substantiates a necessity to apply the
method of interspecific hybridization in durum
winter wheat breeding, using the present soft winter
varieties for improvement of frost and drought
tolerance at the beginning of germination; resistance
to snow mold, fusariosis and bacteriosis of
ears and grain. The article presents the results of a
comparative study of different types of crossbreeding
at interspecific and intraspecific hybridization
due to germination, emergence, productivity. It has
been shown that intraspecific hybrids ‘T. durum
оз. х T. durum оз.’, interspecific hybrids ‘T. durum
оз. х Т. аestivum оз’ and ‘Т. аestivum оз. х
T. durum оз.’ possessed the highest germination
and emergence with 71,8/75,3% for direct and
60,4/82,5% for backward, 42,8 and 35,5% and
55,4 and 64,1% respectively. In backward (triplecross)
cross-breeding of F1 interspecific hybrids
with durum winter wheat the grain germination
was down to 37,4 and 36,6%, but the emergence
was up to 64,1 and 69,7% and reached the level of
intraspecific hybrids. According to the elements of
ear (head) productivity (grain mass per head, number
of seeds per head), interspecific double-cross
hybrids of the first and the second generation significantly
conceded to intraspecific hybrids, but
they matched them in a number of spikelets and
grain size. The triple-cross hybrids exceed the
double interspecific hybrids in this respect, but
they concede to double-cross and triple-cross intraspecific
hybrids. We studied the principle of splitting of interspecific hybrids of the second
generation ‘T. durum оз. х Т. аestivum оз.’ and
‘T. durum оз. х T. durum оз.’ (direct and backward)
and the triple-cross hybrids obtained from
cross-breeding of interspecific and intraspecific
double-cross hybrids F1 with durum winter wheat
The article presents a comparative analysis of the results on available phosphorus measurements in common black soils using the Machigin and Olsen methods. The relationships between maize productivity and soil available phosphorus and also between
phosphorus concentrations in the above-ground plant parts and soil available phosphorus were identified at various stages of crop development
The research is aimed at studying the compatibility of
different doses of ecoventura (TU 9283-199-
10514645-13) and limestone in the diets of rearing of
ducks of "Blagovarsky" cross and the impact on
productive performance. As a result of scientific and
economic experience obtained data on the dynamics of
live weight in groups of rearing ducks indicate that
ecomentors in combination with limestone have a
growth promoting effect and a positive effect on the
growth of ducklings. Best growth depending on dose
administration of ecoventura and limestone in feed
composition had a rearing ducks III (ecomentors
(1,0%) + limestone (3,0%) by weight of the feed) and
IV experimental groups (ecomentors (1,0%) +
limestone (3,5%) by weight of the feed). The results of
the study measurements (body length, keel length,
breast width, chest girth, chest depth) and indices
stature (massiveness, the meat content, arizonia),
which were higher in males and females when fed with
mixed fodder with the introduction of ecoventura and
limestone in an amount of 1.0 and 3.5% respectively.
Introduction to feed composition of ecoventura and
limestone in an amount of 1.0 and 3.5%, respectively
had a positive impact on exterior indicators of rearing
ducks
Results of a complex assessment of hybrids of an apple-tree of new generation are given in article. The short characteristic is given to the best forms. Samples for various selection programs are allocated.
The article analyzes the possibility of complex
processing of one of the most important secondary raw
materials of Krasnodar region – sugar beet pulp with
the aim of obtaining a food product and enriched feed
additives. Meanwhile, the use of environmentally
safety technologies that cause minimal harm to the
environment and human health is provided. One of the
most valuable components of sugar beet pulp after
extraction of sugar is pectin substance. Sugar beet
pectin substances have high complexing ability and are
used not only in food industry, but also in medicine.
They are natural detoxifiers and antioxidants.
Currently, only dry powder pectin is produced from
sugar beet pulp and only by foreign producers. Making
food pectin extracts from sugar beet pulp will not only
reduce the number of processing steps, but also
significantly reduce the cost of the final product. Food
pectin extracts can be used not only as a standalone
product in treatment and prophylactic nutrition, but
also as an ingredient in the manufacture of soft drinks,
confectionery and bakery, meat and dairy products,
etc. The technology of producing a valuable
component of feed bioproduct based on spent sugar
beet pulp and a microscopic fungus of the genus
Trichoderma is described
The article presents the characteristics of the chemical composition of a complex of seven-resistant varieties, introduced in the Central zone of the Krasnodar region, and the quality produced from these natural clarified pasteurized juices, against three of the Eurasian, the control group. We recommend the most valuable varieties for production of high quality juices
The article contains the results of the study of mechanical composition of grapes and biochemical characteristics of white wine grapes for the production of juice of direct extraction and blending. Thus, the yield of studied grapes ranged from 7.5 to 13.2 t / ha: highest yielding varieties and hybrids of Pervenets Magaracha and Tsitronnyy Magaracha, and the lowest - Chardonnay and Pinot blanc. At an average weight of clusters of varieties were divided into three groups - large clusters (230-243 g) in varieties Pervenets Magaracha and Tsitronnyy Magaracha, medium (181-184 g) - the varieties Chardonnay and Pinot blanc, small (112-116 g) - the varieties Bianca and Viorica. By weight of the 100 berries were divided into four groups - Bianca and Viorica (I), Pervenets Magaracha (II), Chardonnay (III), Pinot blanc and Tsitronnyy Magaracha (IV). Weight of 100 seeds from the largest varieties Pinot blanc and Bianca, and the lowest - in the varieties of Tsitronnyy Magaracha and Chardonnay. The solids content in the juices of these varieties ranged from 19.4 to 21.8%, which corresponded to branded products and higher of commodity varieties. Mass concentration of sugars ranged from 18.4 to 21.3 g / 100 cm3. Titratable acid content in the juice was varied from 0.65 to 0.78 g / 100 cm3. Sugar-acid ratio, defined as the ratio of concentration of sugars and titratable acids ranged from 23.6 to 30. The recommended values for this indicator were within 22-30. According to the results of the tasting, we rated "excellent" the juices from the varieties of Tsitronnyy Magaracha, Viorica (19 points) and Bianca (17 points); "good" marks were given to the juices from Pinot blanc, Chardonnay, Pervenets Magaracha: this means that we can get juices of excellent quality from the grape varieties under study with the title of ampelographic variety; in addition, the juice of the grape of varieties Chardonnay, Pinot blanc, Bianca, Pervenets Magaracha due to their potassium content will be functional to improve the cardiovascular system. On the basis of the tasting we have conducted mixing of the juices from the varieties of Viorica and citron Magaracha with other juice varieties 50:50 and 70:30. Sensory evaluation showed that blending juices from the varieties of Viorika and citron juice Tsitronnyy Magaracha other varieties improves product quality and 50:50 increases by one the total score, and 70:30 - two units. Blend of the varieties of Viorica and Tsitronnyy Magaracha does not increase the total score, but gives the product a special flavor and aroma. Hence, using the grape varieties under study we can produce varietal juices with the name of their ampelographic type and blended juices to extend the assortment
