The article contains the review of the basic standards providing ecologically safe recycling of a manure at modern pig-breeding complexes with a Capacity of 12 000 and 50 000 heads of a finishers a year. The capacity of storehouses for liquid fraction is defined

Creation of joint sowings is very complicated modern environmental problem and the solution is impossible without a comprehensive study of the relationship between individuals of different species that are emerging at the level of a plant community. Studying biotic relationships between taxa used in these crops is very important; joint crops include combinations (sowing crops in rows) and mixed crops (crop seeds mixed and sown together); great attention in the mixed and combined sowings has been paid to selection and combination of cultures

The main criteria in assessing the adaptive capacity of Actinidia deliciosa (kiwi), cultivated in Russian subtropics were yield of the introduced cultivars, as well as ecological (stability and periodicity of fruiting) and biological indicators (resistance and periodicity of fruiting). The studied nature of the way Actinidia cultivars react to the constantly changing weather conditions during the period from 1998 to 2011 will help to optimize the placement of the crop in subtropical zone, and use natural resources for its unique climatic properties of Russian territory in a sustainable way

The condition of agrolandscape systems of Kuban has limited number of natural factors, among which an important place is occupied by temperature, moisture, nutrients and places with weediness of sown areas. Basic soils are occupied by cultivation of agricultural crops with a significant presence of segetal communities in the tilled crops, as well as field protective strips. In soils of agricultural landscapes there are actively developing bacteria, actinomycetes and microscopic fungi, the representatives of mesofauna, qualitative composition of which is very varied. When characterizing the soils we can mark a broad aspect of their contamination with heavy metals and oil, as well we pay attention to peculiarities of agriculture

The article comprises the results of two research-and-production experiments with meat poultry and pigs grown on local forages including biologically active preparations. The purpose of the research was to study the effect of enzyme preparations Cellolux-F and protosubtilin G3x and probiotic feed additive “Sporotermin” on the intensity of growth, development and metabolic processes, and conversion of rations nutrients into production. The results of the research showed that to improve the physiological and biochemical status and intensity of metabolic processes in the body, and also improving the conversion of feed nutrients into products in composition of chickens and pigs’ mixed feed one should feed the mixture of enzyme preparations Cellolux-F and protosubtilin G3x with probiotic feed additive “Sporotermin”

There was given the economic calculation of effectiveness of new clonal sweet cherry stocks use in the conditions of south part of Rostov region. There were carried out researches on assessment of different ways of new stock propagation

In the article we have completed an economic evaluation of the use of various types of sweet cherry tree crown in the conditions of the South of the Rostov region

In the Krasnodar region there is a unique gene pool of animals both for dairy and meat. To assess the heifers the authors formed five experimental groups of animals, the most common species in the region. The authors studied the main economic, biological and exterior features: live weight, measurements, assessment of the exterior. The studies found that among intensive species with the largest body weight throughout the growing period, in 8-month old Charolais heifers superior Simmental ones at 17.4 kg. In one year old Simmental heifers were 9.2 kg (R˂0,05) ahead of Charolais and in 15 months – 10 kg (R˂0,05). Over the entire period of growth the highest rates of relative growth rates of heifers were obtained by red steppe breed type named Kuban, which had an advantage over the Aberdeen-Angus – 19.1%, Charolais – 5.6%, Hereford – 6.2%, and the difference between them and Simmental weren’t fixed. When growing, the animals become less tall, more stretched, wide and massive. We have noted that during the period of cultivation we had increased indices: stretch (9% – Red Steppe, 13.8% – Charolais, 16.1% – Hereford); chest (5.4% Aberdeen Angus). This reduces the index of long legs of red steppe – 5.6%, 10.9% for Charolais. The study of linear growth of animals confirms that the animal meat breeds of live weight increase was due to the extension of the body and increase the width of the pelvis and chest. Some different facts were observed in heifers of Red Steppe breed. For them, the most characteristic increase in the width of the chest was 1.44 times, as well as increasing the depth of the chest and chest girth behind the shoulders

The results of the economical and bioenergetics effi-ciency estimation of using fertilizers of various winter barley sorts in the conditions of the South part of Ros-tov region are given and optimal variants of their usage are determined

The content of ascorbic acid (AA) and glutathione (GSH) in spring barley seed of four varieties depends upon hydro-temperature environment (HTE) in different way. The genotype and HTE have equal input on AA content (35 and 34,8 %), and GSH content depends mainly upon “genotype-HTE” interaction (67,6 %).
