This article presents the results of the research of soil cultivation practices and the herbicide treatment ef-fect on the weed content in maize grain crop grown in the stepp conditions of the Krasnodar region. It has been determined that tillering soil with the Wil-Rich disc harrow at 10-12 cm depth is less effective than fall ploughing with a top layer turning-over, chisel and disc tillering combined with summer herbicide treatment. The latter give the advantage of less weeds and higher grain yield

This article proposes a generalized principle of relativity, similar to Galileo's principle of relativity Ein-stein, but for all kinds of real and virtual systems, not just the physical, hypothesis about his relationship with the theorem of Emmy Noether and laws of con-servation of energy, momentum and angular momen-tum in the socio-economic and psychological systems. On the basis of the information theory of time and information theory of value (E.V. Lutsenko, 1980), the conclusions about the non-uniformity of the course of time in social systems, inhomogeneity and anisotropy's of a bench economic space and violations of the laws of conservation of energy, momentum and angular momentum in social systems, and accordingly, of a failure to comply or only partial implementation for them the generalized principle of relativity have been made in the article

The tasks set in "The strategy of engine and technological modernization of agriculture until 2020" provide growth of labor productivity by 3–4 times. In our article, we have attempted to concretize in a zone sectional view the direction action for successful engine and technological modernization for the purpose of implementation of such strategically important point. Radical modernization of system of vehicles for complex mechanization of field husbandry based on the domestic equipment in relation to natural and technological conditions of the Krasnodar region is offered. Realization of system of transport is supposed with use of the equipment of the fourth generation, but in 2020 the equipment of the fifth generation and innovative processing methods for production of grain crops has to be realized. It is noted that the solution of such task without the state participation is impossible. The fundamental principles of improvement of system of vehicles for field husbandry and engine technologies are offered. The main of them is a new system of mobile power, new highly productive motorless grain - beetroot-, forage harvesters, new multipurpose units with the offered devices for combination of the technological operations changing labor-intensive technologies radically. We offer replacement of heavy tractors, self-propelled combines; cutting-down of the nomenclature of the equipment at the expense of multipurpose units, main application of fertilizers along with processing of the soil, drop of sealing of the soil and its dispersion. The offered technical re-equipment of branch will provide precision performance of operations, increase in labor productivity and economy of resources

In this article botanical and morphometrical characteristics of four wild-growing biotypes of Azerbaijan, growing on the Nakhichevan plain - original natural reserve of the richest vegetable gene pool of Eurasia are listed. Unique lianas are discovered, featured and listed under titles of Ajryndzh, Dary-dag, Ilandy-dag and Ordubad. Their comparison on 40 arguments of leaves with reference Vitis vinifera silvestris Gmel. triune herbarium of Russia and Ukraine is resulted

The article is devoted to increasing beekeeping’s earning capacity with rigging and automation of technological processes. Winter is the most complicated and critical period in beekeeping. It influences on further productivity of bee colony. Winter period has specificity – bees are gathering in winter cluster and sustaining temperature in 24…32 °С range inside. This temperature is depending on fluctuation of outside air temperature. For passing winter without complication electric heating is used. Cluster geometry in winter is changing constantly and for optimal regime of electric heating we need to take it into account. Additionally, bees’ activity changing beehive’s microclimate and it’s important to know when beehive’s microclimate adaptive control system is developed. Conducted researches allow us to get basic equations which characterizes microclimate with taking into account of winter cluster’s variable geometry. The equations establish linkage basic parameters of beehive, winter cluster, internal air between outdoor air. Simulation results may be used for adaptive heating control system programming. Additionally, it may be used in special-purpose software for beehive’s microclimate simulation

In this article, the results of researches of the influ-ence of terms and norms of crops of a winter rape on growth and development of plants, winter hardi-ness and productivity of cultures in the changed environmental conditions of Rostov region are re-sulted

The authors of the work offer to apply the new productive kinds of winter wheat: Rosinka Tarasovskaya and Donskoy surprise, and also the use of growth regulators Albit and Novosil, influencing on chestnut soils fertility and wheat crop productivity in dry steppe zone in Volgograd region
