Chemical disinfectants at recommended doses do not impair the viability of Planriz biological agent when applying them in the tank mixture. Planriz reduces injuries of the spring wheat diseases and increases the productivity of culture when mixed with chemicals

In our country, great influence is given to the production and consumption of agricultural animals' meat with high consumer qualities. In this regard, the livestock producers, particularly pigs, are to increase production and improve product quality. Works on using some natural mineral complexes - bentonite and zeolites as a source of macro - and trace elements are performed. The aim of the research is to study the effects of bentonite feeding with free access on the meat productivity and hygienic meat quality of young pigs for fattening. Best effect on the slaughter indexes of fattening gilts had bentonite feeding with free access that resulted in significant superiority of the animals in the experimental group over the control counterparts on pre-slaughter live weight, slaughter weight, chilled carcass weight, slaughter yield, carcass length, the "muscle" eye area and the backgammon weight. More favorable effect in the longest muscle on the dry matter and protein synthesis was provided by bentonite feeding with free access. Due to this, the gilts of the experimental group were in significant advance of their control counterparts in concentration of dry matter and protein in meat. Along with this, the longest muscle of young pigs on fattening in the experimental group had the highest protein value, as according to the protein-qualitative indicator the animals of this group were in significant advance of the control counterparts. Feeding bentonite clay with free access had a strong detoxifying effect that is against control counterparts of gilts in the experimental group showed the significant reduce of lead, zinc and cadmium concentrations in the meat

The paper reviews the results of the study of small moisture conservation basic tillage cultivation technology in corn hybrids of different maturity groups of foreign breeding in areas of unstable moistening of the Stavropol Territory. The biological characteristics of plant growth and development of corn, as well as the formation yields of maize hybrids of different maturity groups, the nature of variation in their productive capacity and economic efficiency of small primary tillage are discussed

The article gives an overview of the study results in the terms of Anapo-Taman zone of the Krasnodar region. It shows treatment effects of the growth stimulants of Avibif and Biodux on Saperavi vine and its productivity and quality

The efficacy of using "Reasil Universal" multicomponent fertilizers on the rice crops. It is found that the greatest effect for seed treatment before sowing and foliar feeding of plants was reached at a dose of 300 ml/t or ml/ha. This gives better grain yield of rice, respectively, 5, 43 and 5, 79 kg / ha

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 %).

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

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

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

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
