German L. Resourses saving elements of the technology for carrot seed growing under the left bank forest-steppe of Ukraine conditions.

Object: forming process of high level of crop producing power and quality of the carrot seed using the root-stecklings. Mission: to draw up technical techniques of carrot seed raising from the queen cell stecklings and to draw up the protective system of seeding from weeds, which will ensure the conservation of it's sowing quality and grading factors in the posterity. Methods: visual, measuring, weighting, chemical, statistical, calculation. Novelty: researched and substantiated regularities of forming of the high level of crop-producing of the carrot seed with normal quality; formed the characteristics (age, size, form index, mass)of the queen cell root-stecklings; proved the influence of building of domestic shrub on it's fertility against the age and sizes of queen cell root and density of seed plants; defined the correlated dependence between observable technological elements and the main factors of growth and development of the seed plants and it's crop capacity; calculated economical and energetical quality of resource-keeping technology of seed raising comparatively to the basic; formed the keeping of the sortal and the main economically-valuable characteristics of the carrot plants using seeds, made from queen cell stecklings. Results: drown up the resource-keeping elements of the technology of carrot seed raising, which help to decrease the square under the seed plants in 1,6 points; to receive in addition from unit of area 2,3 tons of the seed; to decrease their prime cost to 7,1 grivnas/kilogram; in the connection profit of payments from the whole area is 101 000 grivnas; production profitability - 233%(per cent). Index of bioenergetical quality with queen cell raising the biggest - 5,3;energy reading, used for 1 kilogram of the seed, other way round, the lowest - 63 megadjoule/kg. Introduction degree: introduced to the agriculture-business of different forms of properties of Kharkov and Poltavski regions. Region of using: seed growing.
