In this article, the essentially new approach to a way of conducting the central conductor is considered, at formation of trees of an apple-tree on the system of “harmonious spindle”, as one of ways to increase the efficiency of an apple-tree on a stock of ММ-106 at the introduction into fructification in plantings of intensive type, with the placing scheme 5×2 m in the conditions of fertile soils of Krasnodar territory
General characteristic of the productive qualities of laying-hens are given
Zoo engineering expediency of triticale utilization as part of combined fodder for pigs in their growing and finishing is studied. Triticale grain may be used as part of combined fodder for young pigs up to 50 %
The article presents the data of the degree of allelopa-thy-optical activity of extracts from the aerial parts, roots and rhizosphere of weeds, which is manifested in the inhibition of germination of winter wheat. Rusty-negative balances of cockle and wild oats, containing cellulose and decomposing slower, depress the test-culture of winter wheat after mineralization within 30 days
In this work, the influence of 10 stimulators on occur-rence of roots in plants of green shanks of 14 types of stocks of fruit crops is shown. Types of preparations are allocated, at which qualitative root-stocks mate-rial for each investigated genotype in a hothouse with the mechanism forming a fog are received

The researches have been carried out on hogs of Steppe type (ST) of fast-ripening meat breed (FM – 1), large white breed (LW) and their cross-breeds ST*LW, LW*ST. Researches showed that gilts LW excelled the patterns of PSE – port in pH. NOR – port, in its turn, was distinguished by higher contents of components composing dry and organic matter. The superiority of cross-bred hogs ST*LW over LW*ST according to the quantity of triptofan in pork was determined. The analysis of physic-chemical properties of fat has shown, that gilts of Steppe type with PSE – pork were distinguished by lowered to of fat melting and increased iodine quantity against NOR – quality pork
