Garmashov V.V. “Adaptation of sorts of winter crops and ecological and biological basis of regulation of their productivity in the Ukrainian Steppe” - Manuscript.
Dissertation for competition of academic degree of doctor of agricultural sciences on the profession 06.01.09 - plant growing. National agrarian university, Kiev 2002.
In the dissertation there were established the regularity of growing up and of the development of different sorts of winter crops (medium-sized, semi dwarf, soft and hard), specificity of forming of their adaptation and productive potential, quality of grain, their reaction on different weather conditions, agrotechnical methods and factors of biologization of technologies in the dissertation. The complex of methods that are in basis of the biological (nature protecting) technology was founded and developed on this basis, there were also optimized conditions for using resources of the environment by the plants, taking into consideration genotypic peculiarities of different sorts.
While studying of the microbiological, water regime, photo sanitary fettle of the sowings, there was established the uniformity of functional characteristics of mineral nitric and phosphoric fertilizers and of chemical remedies for plant protection and of their biological analogues. It founded its reflection in the sizes of the crops and on the quality of the grain.
Ecological and energy expediency of the introduction of the biologicals into the technologies instead of or in addition to their chemical analogues is confirmed by considerable reduction of the prime cost of the final production and by increase of the profit.
Key words: winter crops, sorts, growth process, biologicals, adaptive potential, germination, spending of the winter, reutilization, crop, grain, quality.
