Food security of the Republic of Belarus: modern tendencies
The tendencies, regularities and problems of the world system development and their influence on security in the food sphere of different countries are investigated in the article. The tendencies and forecast of the world food system development are described. The analysis of the factors determining the potential of threats and challenges of modern times and countermeasures are presented. The results of monitoring of food security in the Republic of Belarus are stated. The monitoring has been conducted in accordance with the methods, criteria and indices of the National Food Security Concept. The potential of threats is identified, and the measures which are necessary to prevent their approach are substantiated.

Improvement of the mechanism of government regulation of the agroindustrial complex
The article deals with the conceptual bases of the model of private and state partnership. In this connection the directions of further improvement of macro- and microeconomic conditions of an effi cient economic management are defi ned. A special attention is drawn to the creation of a multilevel system of agroindustrial formations on the basis of cooperation and integration. Presented are the recommendations on improvement of foreign trade in agricultural products, system of pricing and taxation, labour relations in agroindustrial complex, and also intergovernmental regulation of agroindustrial production.

Conceptual approaches to formation of the integration field of food competitiveness under the conditions of functioning the Common Free Market Zone of the Customs Union States
Under the conditions of an insufficient competitiveness of the domestic market and the quality of economic growth of the Belarusian economy strengthening of the national food competitiveness is the most important priority. It's possible to make this priority come true through taking the advantage of the regional economic integration within trade and economic communities of the Common Free Market Zone. It's established that the integration field of food competitiveness of the Common Free Market Zone countries is beginning to change its sizes that brings about the necessity to modify the economic interaction of its countries. To achieve the indicated purposes an institutional model of the innovative-cluster food system of the Common Free Market Zone has been created. This model is based on the relations of innovative enterprises and developed branches of the agroindustrial complex of the countries within international food clusters that promotes the formation of an co-competitive field within the Common Free Market Zone and creates good opportunities to single out and develop specialized segments on food markets.

Agrogenic evolution of phosphate fractional composition of Polesye peat soils
The results of the research on studying the infl uence of drainage and long agricultural use (50 years) of peat soils on the transformation and content evolution as well as on the structure of phosphate fractions are presented. Under the infl uence of anthropogenic factors along with the reduced content of organic matter in soil the equity participation of organic compounds also decreases from 88 to 62% and mineral compounds specifi c weight increases. Relative reserves of mobile (from 5 to 35%), accessible (from 0.8 to 6.8%) and easily accessible (from 0.8 to 5.8%) phosphate compounds increase. As soon as the content of organic matter in soils reduces their phosphate fund becomes more "crumbly".

Change of the content and composition of mobile humic substances in sod-podzolic soils under the influence of different systems of fertilization
The infl uence of different systems of fertilization on the content of mobile humic substances and their structure in sodpodzolic soils is studied. The most effective way to increase the content of mobile humic acids as a part of mobile humus is the use of organic and organic-mineral systems of fertilization combined with straw ploughing.

Influence of climate warming on optimal terms of winter cereals sowing
The analysis of changing heat supply of autumn vegetation of winter cereal crops in 1996–2011 in comparison with heat supply according to the climatic norm in 1940–1970 is presented. It is shown that within the analyzed period, as a result of climate warming calendar terms of the beginning of sowing winter cereals moved by 4–10 days, and the end of sowing – by 1-5 days.

Phenology of pear psyllid (Рsylla pyri l.) and pear sucker (Psylla pyrisyga Först.) development under the conditions of Belarus
In the article the results of researches on phenology of pear psyllid (Psylla pyri L.) and pear sucker (Psylla pyrisyga Fö;rst.) development are presented. The periods of development of each generation of these pests are presented. The influence of average daily temperatures and relative air humidity on pear psillid embryo and post- embryo development is defined.

Genotypic peculiarities of the development of vegetative sphere of taxons р. Oxycoccus in the experimental crop on the exploit peat bog of the north of Belarus
The paper presents a comparative evaluation of biometric indices of the growth of vegetative and generative shoots of 9 taxons Oxycoccus of European cranberry (O. palustris L) and introduced varieties of American cranberry (O. macrocarpus (Ait.) Early Black, Ben Lear, Franklin, Searles, Wilcox, Stevens, McFarlin and Pilgrim when they are grown on the peat bog in the north of Belarus during contrast seasons. It is shown that with the leading position of the variety Stevens in the development of a vegetative sphere, most varieties of American cranberry under the conditions of temperature stresses have more new generative and vegetative shoots. It is accompanied by the increase of the degree of their foliage and the size of leaves without form changes what should promote the work of photosynthetic apparatus of the plants.

Results of breeding for creation of the plant type of pigs "Berezinsky" in the Belarusian meat breed
As a result of purposeful breeding work a perspective genotype of pigs of the Belarusian meat breed was created. This genotype combines high reproductive traits, increased growth energy at low forage spends, and allow to obtain competitive pork. Thus, breeding sows of the plant type are characterized by high indices of reproductive traits, repairing boars – by a high growth energy, thin fat. A high level of fattening and meat productivity of young pigs of the plant type "Berezinsky" in Belarusian meat breed is identifi ed. Animals of the new plant type are well adapted to the conditions of the industrial technology of Belarus and are widely used in the republican program of crossing and hybridization.

Age peculiarities of carbohydrate and lipid metabolism of pigs while rearing them at large industrial enterprises
The article studies the dynamics of indices of carbohydrate and lipid metabolism of pigs while rearing them at large industrial enterprises. The research shows that within the fi rst 60 days of living the level of glucose, lipids, triglycerides and cholesterol decreases, and the level of lactic acid increases. The most critical periods in respect of glucose insuffi ciency are 80 day age and 105 day age of pigs. At the age of 180 days the indices of carbohydrate metabolism as well as lipid metabolism decrease.

Mechanization – priority N1 in the development of agriculture of the Republic of Belarus at the present stage
For a stable increase of the economic potential of rural areas and of the whole country in general a high level of agricultural production is necessary. The article analyses the state of agricultural production for the last two decades. A number of unsolved problems in agriculture are shown. One of the main problems is quantitative and qualitative discrepancy between the car park and the required amount of work. A necessity to develop and implement a scientifically grounded program of priority agricultural machine-building is stated. Its will allow to create the background for technical supply of intensive technologies in plant breeding and animal husbandry all over the country. The structure of the program is grounded.

Substantiation of the assessment criteria of soil adhesion to potato tubers
The author of the article considers some theoretical aspects of infl uence of potato cultivation technology and soil characteristics on soil adhesion to tubers as major factors, determining operating effi ciency of pile separation devices and tools of a machine for pre-sale potato cleansing. The assessment criterion of soil adhesion to potatoes on the basis of the Rozin-Rammler equation parameters is suggested. It will allow to substantiate the required fractional structure of a soil layer and a choice of technological operations in the process of soil cultivation.
