Detoxication mechanism of protein deterioration products in heat resistant apple trees (Florina variety) under overheating is substantiated. Apple trees drought and heat resistance increase in non-irrigated orchard is obtained under over-row spacing turf-covering with naturally grown grasses
The organization of animal feeding in the summer and
procurement of fodder for the winter are of great importance.
The sowings of sugar sorghum can become a
reliable and stable source of fodder even in the regions
with insufficient humidity. It is a unique drought tolerant
crop, which can be used as green mass, hay, silage,
grain, mono fodder, briquettes. The article gives the
study results of green mass and absolutely dry substance,
and the assessment of cultivation efficiency of such sugar
sorghum varieties and hybrids grown in FSBSI ‘I.G.
Kalinenko ARRIGC’ as ‘Zernogradsky yantar’, ‘Debyut’,
‘Listvenit’, ‘Zersil F1’, ‘Elisey F1’. The productivity
of green mass and dry substance of the new variety
‘Listvenit’ and the hybrid ‘Elisey’ exceeded the standard
variety on 7,0-5,0 t/ha and 2,30-0,74 t/ha respectively.
The cultivation technologies of sweet sorghum varieties
and hybrids produced the high net energy of 69,6-121,9
GJ/ha with the coefficient of energy efficiency of 3,72-
5,08. As for the energy, the cultivation technology of the
sweet sorghum hybrid ‘Elisey’ can be considered as the
most efficient variant, as it produced the maximum net
energy of 121,9 GJ/ha with the coefficient of energy efficiency
of 5,08
A stationary experiment at Agrochemistry chair of Kuban' state agrarian university has revealed certain changes in humus contents and physical and chemical properties of black leached soil after two stages of field crop rotation as a result of long-term application of mineral fertilizers
The article shows the parameters of changes in microclimatic and soil conditions of interbelt cells in the system of field protection plantings
The article presents the results of the studies of 11
varieties cultivated in the eastern region of South Coast
wine-growing zone of Crimea (planting of
"Solnechnaja Dolina ", near Sudak mountain) in the
area of their natural growing, where was formed the
gene pool of grapes for a long time. As a result, the
three-year (2010-2012) study found that the majority
of indigenous varieties had small number of fruitbearing
shoots in the bush: the varieties with colored
berry - 53,3-73,3%, in white-berry - 46,6-75,9% except
Shabash variety - 79.9%. We have identified the most
productive varieties which were Dzhevat kara (62.2 t /
ha), Kokur Beliy (48.9 t / ha), Kapselsky Beliy (44.4 t /
ha), and varieties with female type of flower: Kefesiya,
Ekim kara, Kock pandas, Sary pandas and Crona gave
not high yield: 22.2; 22.2; 24.4; 28.9 and 28.9 t / ha.
On the strength of growth, productivity and the
accumulation of sugars in the juice of berries, we
picked out varieties of Dzhevat kara, Crona, Kapselsky
beliy. According to the main economic indicators, it
turned out that the most profitable varieties are
Dzhevat Kara, Kokur beliy and Kapselsky beliy.
Hence, these varieties in conditions of the Crimea have
much greater prospect of reproduction and
development of production
The article reviews the results of the study of the influence of treatment of vines of Saperavi with lignohumate of grade "B" on its uvological and fruitful properties in the Anapо- Taman zone of the Krasnodar region
New varieties of winter durum wheat selected by methods of complex crossing varieties of winter durum wheat of different ecological-geography region and their mutants differ with quality of grain adaptability to econiche. Value of chemical mutants in selection of winter durum wheat on adaptability and quality of grain is discussed
One of the methods of increasing the productivity of alfalfa is the use of growth regulators, and the use of polymeric compositions of growth regulators, binders with synthesized growth regulators of sim-triazine series is promising with the possibility of creating environmentally friendly technologies for growing alfalfa. Studies have shown that the application of the test on alfalfa growth regulators has a positive effect on growth, physiological and morphogenetic processes, plant resistance to adverse environmental conditions. Intensity impact on plant growth regulators depends on the type of plant growth regulators, concentration and method of application. Processing alfalfa seed growth regulators on germination increases energy 3,0-14,0 % germination on 8,0-17,0 %. Processing plant growth regulators to enhance the growth of plants in height (on the 7th day – 2,6-11,9 % , on the 14th 41,9-48,0 %) , the growth of aboveground biomass , expands on the number of productive branches of the 1st ( 24,1-41,3 %) and 2nd order (21,7-55,0 %). Pre-sowing seed treatment and plant growth regulators alfalfa sim- triazine series contributed to the increase in seed yield of 15,5 %. On average, the yield of green mass increased by 0,8-2,4 t /ha or 5,2-15,5 % and seed yield at 0,19-0,42 h/ha or 8,7-19, 3 %. Growth regulators of sim-triazine series increase the protein content of the vegetative mass of alfalfa at 3,2-4,6 %
The article shows prospects of the use of growth regulators on the nature of humic culture of rice in the first place due to the low field germination of seeds, rice crops lodging. Effect of humate on the growth, development and photosynthetic activity of plants, as well as the consumption of nitrogen, phosphorus and potassium results in increased grain yield of rice. Depending on the type of humate yield increased by 5,0-6,4 с/ha. Seed treatment caused a change humates biochemical and technological indicators of the quality of grain. Beans with these options contain more than in the control of protein per 0,13-0,44 % starch - 0,36-1,2 %, decreased membranous grain by 0,2 % and 1 % fracture, raised on vitreousness 1,46-2,0% and the yield of cereals on 1,06-2,0 %
In the article, the results of the analysis of agrometeorological factors of formation of a crop of long-term cultures are resulted. The regressive correlation analysis of the given conditions and growth of bean and cereal grasses has allowed to establish high correlation dependence between change of a crop and number of days of growth for cereal herbage. It is noticed, that change of the efficiency of the bean is less closely connected with time of formation of herbage, than cereals. Also, for fertilized bean and cereal the correlation factor between the crop and the term of growth of the grass is higher, than for not fertilized ones. The backward correlation dependence between the changes of the maintenance of a raw protein, ashes in a forage from the first hay crop of cereal herbage and, accordingly, the sum of temperatures more 5°С is established
