TO THE QUESTION OF THE INTEGRITY OF SOCIO-ECONOMIC SYSTEMS
DescriptionThe article considers the main principles of the system approach and their use in the general disclosure mechanisms in the organization of the systems as holistic entities. Ontological and epistemological lines of the concept of the system and highlights the main properties of systems are reflected. Since the system acts as a form of organization of tangible and intangible objects, integrity is determined as the necessary property of sustainable living systems. The concept of sustainability from the point of view of general systems theory is considered, its types are distinguished. Features of the economic systems and the specificity of the concept of their stability is described. It is marked that the majority of biological, technical, economic and other complex systems are characterized by non-Gaussian distribution and as a necessary formal feature of consistency (integrity) of the studied object the presence Zipf-distribution in the population can be used. Differences between the coenoses from deterministic systems and probabilistic objects are marked. Procedures performed in the course of the ranking analysis and the theoretical aspects of optimization of cenoses by holding an item or parametric optimization are considered. The proposals on the use of ranking analysis and rank distributions that are widely used for the study of technocenoses, in the research process and the formation of economic systems are promoted

AGRO-ECONOMICAL ASPECTS OF GROWTH STIMULANTS AND MICROFERTILIZERS APPLICATION ON BUCKWHEAT
DescriptionThe article highlights the food value of buckwheat. It is said that the achievement of its biological potential under prevailing conditions of cultivation is impossible without the introduction of modern scientific and technical progress. The authors describe variants of integrated application of growth stimulants and microfertilizers in buckwheat production technology. Recommended technologies have been tested in conditions of the Central Chernozem region. It is revealed that the best variant of pre-sowing seed treatment is the combination of Epin-extra and Rexolin ABS. Conbination of Epin-extra and Speedfol B is the best variant of treatment of vegetating plants, providing the maximum yield increase in comparison with control variant (without treatments). Economic efficiency of all proposed technologies was studied. The system of indicators was chosen, which evaluate the efficiency of 36 variants of seed and plant treatment with growth stimulants and microfertilizers. A comparative analysis of variants demonstrated that the application of Speedfol B in combination with EPIN-extra and Rexolin ABS is most cost-effective and profitable. It is noted that the final choice of combination of growth stimulants and microfertilizers will depend on the specific conditions of cultivation. Recommendations are given

Description
The results of the study presented showed that predator mite Ph. persimilis exhibited high food preference of the larval stage (30,2% of the total number consumed) compared to the egg (20,5%), nymph (13,4%) and adult (10,1%) stages of two spotted spider mite T. urticae. The functional response of Ph. persimilis feeding on eggs and adults of T. urticae was described by the Type II curve. At a maximum density of 60 prey per leaf disc, Ph. persimilis consumed an average of 22.8 eggs and 3.2 adults over an eight-hour period. Calculated time for handling of the prey by Ph. persimilis was on the average 0.074 hours (4.4 minutes) and 3.2 hours for T. urticae eggs and adults respectively. The mean number of T. urticae eggs consumed by Ph. persimilis progressively increased with the increase of the prey density, but the rate of predation (number of eggs consumed/prey density) decreased from 0.5 to 0.3 with the increasing of prey density. The mean number of adult T. urticae consumed by Ph. persimilis at densities of 20, 40 and 60 per leaf disk remained relatively constant. But the rate of predation decreased from 0.09 to 0.04 with increasing of prey density. The experiments showed that regardless of the strategy utilized by the predator it was the one that was efficient for the predator survival
