harmfulness of pink sonchus in sunflowers plantations
The newest high-tech pink berry aromatic grape variety Hara selected by hybridization at the Athens Institute of Viticulture (Likovrisi, Greece) researchers P.K. Zamanidi and L.P. Troshin in 2004 by crossing the Greek varieties Avgulato with Traminer pink. According to the morphological and physiological characteristics related to the eco-geographical group of Black Sea. Growth of shoots is strong (2,1-3,0 m). Degree of ripening vines is very high (over the entire length other than top of shoot). Length of production period from bud burst to harvest 146-155 days. Productivity is very high, 25-30 t/ha. Percentage of productive shoots - 90. The average mass of clusters within 350 g. Characterized by a high winter hardiness, drought and increased resistance to fungal diseases in comparison with varieties Vitis vinifera. Hermaphrodite flower with stamens and fully developed gynoecium. Cluster medium, conical, medium density. Berry medium, spherical, pink color, with a thick waxy coating. Peel of medium thickness, dense, durable. Pulp and juice with pronounced varietal flavor of Gewurztraminer. Sugar content is very high, more than 24%. When overripening dry-curing and continuously stored on the clusters. Variety intended for the manufacture of dry white wines of excellent grade and high-quality dessert and sweet wines; suitable for production of high quality juices, compotes
The results of studying of growth, fattening and meat qualities of marketable grosses from large white, Landras and Dyurok breed crossing have been cited in the article. Optimum pig weight when early weaning was established
The article deals with a combination of different methods
of cultivation of winter barley on the background
of plowing, and their impact on growth, development
and crop yield. The main technological factors allowing
implementing the biological potential of culture are
adaptive variety, quality seeds, predecessors, sowing
and harvesting, fertilizer, soil fertility, crop care, including
protection from weeds, pests and diseases.
Barley is the culture of versatile use, which is grown
for food and feed purposes. Intensification of cultivation
methods of this phenomenon is essential and significantly
affects the grain yield of this crop. Under the
natural fertility of the soil and favorable weather conditions
for black earth of Kuban it is possible to get
3,0-3,5 tons per hectare of winter crops of grain, and
this requires the creation of an optimal diet, because
one of the main factors affecting the productivity of
field crops, including one phenomenon are fertilizers.
In addition, the level of soil fertility and protection
system of weeds, pests and diseases has great importance.
Since these types of issues are relevant for
agriculture, we have carried out studies to identify the
optimal combination of different methods on growth,
development and productivity of a single phenomenon
In the article, we have studied the effect of feeding of the germinated cereal crops on the growth, development and reproductive qualities of heifers
We have selected a group of test animals and formed a
set of techniques for the research. The article gives an
evaluation of fattening qualities (precocity, average
daily gain, feed consumption per 1 kg of gain) of
purebred and crossbred pigs. We present the dynamics
of body weight and body length for the experimental
pigs, productive qualities, the thickness of back fat of
experimental animals to achieve the 100 and 130 kg of
live weight
The article presents the growth and the condition rates of field protection plantings of Lipetsk region, depending on agricultural practices of creation
A comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation
The article is devoted to the study of growth peculiarities of summer potato on floodplain lands of Southern Russia. High and stable yields in big farms are possible using substantiated planting time of potato which depends on specific soil – climatic conditions of the area as well as potato cultivation technology elements improvement under irrigation. The latter will provide in turn water and power resources economy. The results of field research to determine planting time allow defining the most favorable conditions for potato cultivation in the given soil-climatic zone. The analysis of data obtained on differential irrigation regimes gives a possibility to determine common regularities of irrigation standards impact on potato growth efficiency. The regime proposed is in conformity with the concept of ecological land reclamation and takes into account a moderate anthropogenic impact on landscape processes under a permissible level of summer potato productivity decrease. Therefore proposed optimal time of summer planting and rational irrigation regime will increase industrial efficiency of potato production and provide environmental safety of irrigation on floodplain lands of South Russia while allowing to economize water and power resources
The article deals with the data of green manure crops growing on irrigated lands in the Rostov region and their impact on the yield and quality of potato of summer planting time
