The article reviews economic aspects of efficiency
improvement of the national breeding capacity in rice
growing. It is noted that there are no foreign rice varieties
in the RF State Register of Breeding Achievements
approved for use. However, only 2 - 3 leading rice
varieties cover more than half of the rice acreage and
thus reducing the efficiency of the existing varieties
potential of the economic sub-sector. The critical importance
of breeding and the wide-spread introduction
into production of rice varieties resistant to disease is
highlighted. The cyclic and growing occurrence frequency
of blast as the most harmful disease of rice is
shown. The data are provided on the increase of the
annual cost of the rice crop and fungicide treatment
and reduced yields of different varieties of rice during
epiphytoties. A refined formula is proposed for calculating
the annual economic effect of the introduction of
new rice varieties. The formula takes into account
changes in yield components, grain quality, the cost of
breeding and introduction of new varieties, as well as
the potential cost savings due to rice resistance to blast.
The seeds of domestic long-grain rice varieties and
exclusive varieties resistant to blast are available for
the Russian market. For a wider introduction into production
of all local bred rice varieties, it is necessary to
actively develop seed production, improve market research
as well as the management efficiency in plant
breeding and seed production
The article considers the questions of efficiency of the program-target management of agro-economic systems development of the region. The methodical efficiency assessment approaches of target programming of fruit and berry industry of the Krasnodar region are shown in the article
The article provides the data of the researches of studying of samples of haricots varieties and selection the highest yield for the conditions of the Azov zone of the Rostov region, and also their economic assessment
The article reflects information characterizing the significance of mastitis and endometritis in the indicator of premature disposal of cows from herds of large farms in the western regions of the Krasnodar region: an average of 30% of the total culling of cows. The effectiveness of veterinary measures in Pravoberezhny JSC of the Temryuk district for mastitis and endometritis in cows was assessed: 81-95%; fertilization index value ‒ 1.8; the duration of the service period exceeds the requirements by 20 days. The studies the nature of the influence of the drugs called Sepranol and Uteroton on the calving process and the occurrence of postpartum complications in cows from the herd, which was formed with violation of breeding principles. The use of the drugs Uteroton and Sepranol contributed to a 50% decrease in the calving index in calving cows by 50% compared with the results of the combined use of estrophan and oxytocin. The use of Uteroton reduced the damage from the lack of milk by 87880 rubles, and the use of Sepranol - by 171164 rubles. We have given practical recommendation on the use of Uteroton and Sepranol for veterinary effects on the body of cows in the early postpartum period in order to reduce the occurrence of complications
To solve the problems of full-value feeding for pigs, it is offered to use protein-vitamin-mineral additives as a component of rations. It allows increasing live weight gain, average live weight gain and improving feed conversion efficiency per 1kg of live weight gain
This article presents the data of the research of new
feed additives’ effects on the dynamic of
hematological indexes and milk productivity of cows
The effects of increased water temperatures on the reproductive characteristics of rainbow trout females were studied. It was found, that the increased water temperatures produced negative effects on the gonad maturation and survival of the embryos when acted at the late stages (IV and V) of female gametogenesis, but not at the earlier (III) stage
Increased range of Syringa in landscaping is a topical issue. They are very decorative shrubs, more and more widely used in landscape design. Study of vegetative propagation of plants, with the use of growth regulators, was conducted to identify the most perspective stimulator and to reduce the terms of the finished product. Syringa refers to bad rooting cultures. However, the methods of green propagation of cuttings with the use of growth stimulators not only propagate a culture, but also increase the yield of landing products. The article considers the technology propagation by cuttings of this promising shrub. It also shows the effect of growth stimulators: radifarma and HB-101, used for soaking of cuttings. According to the research, we have found an apparent benefits effect of the processing of cuttings with the stimulators on growth and development of root system. The analysis of the tables of rooting rate of cuttings shows the positive development of cuttings in the processing of the growth regulators. We have obtained the experimental data allowing to define which varieties distinguished by the greatest rooting and duration rooting among all the studied cultivars. Thus, the studies show that the use of growth stimulators with propagation of Syringa cuttings is an effective way of reproduction
The article presents the results of the research of the density of wood, affected by various types of fire. The analysis of structural changes in the wood, based on its micro and macro structure is given
Grapes are product of areas. Grape plant is very plastic
and can grow on almost all types of soils except highly
saline, fusion and wetlands. In studies of many
authors, it was indicated the influence of different soil
types and their properties on the growth of the vine
plants, the quality of berries and their products. The
object of study is soils and vines growing on them,
laws and processes affecting the formation of grape
production. Research methods are expeditions, field
and laboratory. The article presents data on the effect
of agrochemical soil properties (pH, solid residue, the
amount of aqueous extract ions, chlorine ions,
alkalinity (НSO3¯), calcium ion, magnesium ion, total
carbonate, active carbonates, nitrate nitrogen, mobile
phosphorus, exchangeable potassium , humus, humus
reserves) on the formation of the harvest of grapes and
wine products (tasting score, the extract, the amount of
phenolic compounds, the amount of organic acids, the
amount of amino acids, metal ions, potassium ions,
sodium metal, magnesium ions, calcium ions, the
amount of metal ions). With the help of statistical data,
we can establish the effect of weather conditions on the formation of 2009-2011 qualitative wines of
Cabernet Sauvignon
