Problems and prospects for flax cultivation
The tendencies of the world flax market, the analysis of the branch conditions, the proposals on rising the efficiency of the Republic flax subcomplex and the development of raw materials base, the perfection of the flax processing technology and the pro-cessing of flax products, and also the directions of improvement of the organizational structure are considered in the article. In modern conditions the world flax market is created and operated on the basis of perfecting scientific support, applying modern technologies, intensifying production at a decrease of crops and price cut on raw material. A feature of the modern market is the extension of the sphere of application of flax production. Under the forecasts of the leading foreign fashion designers in the nearest years the specific weight of flax and flax-containing fabrics in the total amount of output can be increased up to 70%. It is expected that natural fibres will be widely used in different branches of economics. In Belarus, for saving the positions on the world flax market it is necessary to take into account the present and perspective tendencies of production and usage of flax. The implementation of perspective possibilities of development of the market when actively influencing its conjuncture requires not only the overcoming of available problems of subcomplex operation, but also the support of balanced development by means of complex solution of problems of production of raw material, its processing and sales at the considerable rising of quality parameters of products.

Influence of the seeding depth on the formation of plant density and productivity of summer rape
The influence of the seeding depth of summer rape seeds on the dynamics of occurrence of shoots, formation of plant density and productivity is investigated. Researches were carried out in 2002–2004 on sward-podzolic loamy soil. It is estab-lished that the field sprouting of rape seeds depends on the soil conditions at germination. The greatest field germination is obtained at a depth of seeding of 15 mm. It was varied from 34.1 to 64.7 % depending on the conditions of year. The field germination at a depth of seeding of 35 mm was up to the standard of a variant of 15 mm in favorable soil conditions and reduced to 17.9% on structureless surface soil. Germination of seeds at superficial placement occurs after loss of rains. The shoots appear late, the field germination is reduced by 58.9–81.3% at superficial (0 mm) and deep placement (50–100 mm) in comparison with a variant of the depth of seeding of 15 mm. The depth of seeding renders the essential influence on the formation of a crop by means of the action of two major fac-tors: 1 – term of occurrence of shoots; 2 – density of plants. The summer rape crop is reduced by40.0-58.1% at superficial and deep seeding in comparison with the depth of seeding of 15 mm.
