Complex researches have been conducted in the Tver region on sod medium podzolic sandy loam well-cultivated soil. We have studied implementation of crop yield programmable levels by means of vetch-barley-oats mixtures different in composition. The advantage of their cultivation on grain-and-hay has been revealed, when the program both at the background of 2.5 thous. feed unit /ha and 5.0 thous. feed unit /ha on all variants of mixed crops was exceeded. Program has been carried out only at the programming level on 2.5 thous. feed unit / ha when growing mixtures for grain.

The causes of the disposal of the animals and the main milk productivity indices of cows having different genotypes depending on the method of housing and technology of milking have been analyzed. For all the evaluated periods the animals which were milked with a robotic system in the free stall barn surpassed the cows which were kept on a leash and milked into the pipeline with the help of milking machines. Along with this, in the cows kept in the free stall barn the limb diseases caused culling more often than in other groups of animals under study.

Main phytophagous species belonged to the families of Coleoptera, Heteroptera, Homoptera, Lepidoptera are determined on seed crops of Galega orientalis on the sod-alsopozoriti soil. Longstanding research has established the influence of weather on the population dynamics of the pest and high efficiency of decis and bitoxybacillin of 85.5-95.5 %.

Data on species composition of fresh-water mollusks, representatives of Gastropoda (Cuvier, 1795) under the conditions of the Vologda region are provided. 27 types relating to 10 childbirth: Aplexa (Fleming, 1820), Physa (Draparnaud, 1801), Lymnaea (Lamarck, 1799), Anisus (Studer, 1820), Armiger (Hartmann, 1840), Planorbis (Geoffroy, 1767), Segmentina (Fleming, 1818), Bithynia (Leach, 1818), Valvata (O.F.Müller, 1774), Viviparus (Montfort, 1810) are determined. Dominating look is Lymnaea truncatula, Müller, 1774. The main groups of biotopes are defined.
