Prerequisites and perspectives for creation and development of the secondhand market of agricultural techniques in Belarus
Prerequisites and perspectives of creation and functioning of the secondhand market of agricultural techniques in Belarus have been investigated. Its development gives possibility to improve equipment of agricultural commodity producers of wide range who cannot buy or receive on lizing new machines and for who to buy new equipment is economy inexpediently. Objective conformity in creation and develop-ment of the secondhand market of agricultural techniques has been discovered as a result of data of special questionnaire poll among heads and chief specialists of agricultural organizations and agri-servise enterprises of Minsk and Grodno regions. It is important as for agri-servise enterprises that will renew agricultural techniques as for agricultural organizations that are consumers of these techniques. It has been presented experience of functioning of the secondhand techniques market in USA, Grate Britain, Germany and some regions of Russia it needs to use the experience in conditions of Republic of Belarus taking into account an interpretation.

Accumulation of 137Cs and 90Sr radio nuclides by leguminous plants of various kinds
Decision of protein problem at territories polluted by radio nuclides as a result of the accident at Chernobyl NPP is not possible without increase of the sowing areas of leguminous plants (peas, lupine and soybean). Introduction of sorts having low level of accumulation of radio nuclides (peas — Aist, Agat, Gomelskaya; soybean — Mageva, Pina, Severnaya zvezda) into agriculture shall allow have agricultural production complying with demands: «Republican acceptable level of a content of 137Cs and 90Sr in agricultural raw materials and forages» at arable lands at their higher density of radioactive pollution: 137Cs — 925—1110 kBq/m2 (25—30 Ci/km2) and 90Sr 15—18 kBq/m2 (0.40—0.50 Ci/km2).

The mechanisms of introduction of Сorynebacterium glutamicum into sterile and not sterile soil
The Corynebacterium glutamicum population, which is industrial producer of lysine was added into sterile and not sterile soil. Soil microbe complex influenced negatively on researching population surviving, because introduced bacterium survived twice longer in sterile soil than in not sterile and were not detected only on 60th day. The adding of Corynebacterium glutamicum into not sterile soil caused growing of microorganisms total number and increasing of catalase activity. These parameters were not differed from the control after one month that indicates soil microbe complex restoration with alien population dying.

Influence of long-term application of mineral root-inhabited medii onto productivity of tomato fruits
Results of investigation of dynamics of properties changing of mineral friable substrates carrying out in hothouse conditions for proving their duration and optimization of food mode of operation improving tomato production have been presented. Perspective substrate for Republic of Belarus is the claydite possessing row of advantages.

About effectiveness of entomophilies pollination of meadow clover (Trifolium pratense)
Dependence of seed productivity on a level of entomophilies pollination of meadow clover (Vitebchanin sort) has been studied at various phones of saturation of sowings by insects-pollinators at close sowing and continuous sowing. It has been found that seed productivity can reach up to 10 centners/ha at saturating phone of insects-pollinators (60000 effective visits of flowers per 1 m2). Clover can have potentially high seed productivity in sowings of special constructions that significantly activate work of insects-pollinators.

Development of fungi of Fusarium genus — causal organism of fusarium diseases of narrow-leaved lupine (Lupinus angustifolius L.) in dependence on a temperature and nutrient medium composition
Morphological-cultural peculiarities of species of F. oxysporum and F. avenaceum — causal organisms of fusarium diseases of narrow-leaved lupine and role of temperature and acidity of nutrient medium in their development and accumulation of infectious material have been studied. It has been stated that the most favorable condition for cultivation are potato-glucose agar at temperature of 20—27 °C and at pH of nutrient medium equal to 5—7.

Comparative effectiveness of use of cakes from different oil crops in calves ration
Negative influence of introducing to KR-3 mixed fodders composition of rape and mustard cakes onto forages consumption, nutrients di-gestibility, physiologic state and productivity of young cattle has not been stated as a result of scientific-economic and physiologic experiments. Nutrients digestibility was 78,6—91,3% at feeding of experimental groups of calves by mixed fodder including 15% rape and mustard cakes and that was 71,6—91,5% at feeding of control group by mixed fodder including sunflower cake. Average daily growth of living mass was 846—875 g at 9,70—9,97 f. u. fodders expense per 1 kg of growth. Any differences on slaughter indexes and meat composition have not been stated.

Use of DNA-technologies in stress sensible determination and productivity of pigs
Carried out researches and DNA-testing of purebred and crossbred Belarussian black-and-white and large white pigs had shown the connection between polymorphysm of RYR 1 gene and fattening and meat productivity. It has been marked a decrease of meat productivity indexes of black-and-white and large white crosses having blood relationship of 25% of Landrase and Pietrain breed being heterozygous on RYR 1 gene at 8,4—2,8% and 0,3—8,0% respectively.
