SUMMARY. The thesis present the results of the field researches having been carried out for years and aimed at studying the effect of different methods of main soil tillage on physical and chemical fertility indices in dernoik soil as well as weed density, growth, development and productivity of winter rape. Economic and energetic analysis of the methods of soil tillage have been carried out. It has been found out that non-tillage methods of soil treatment increase the density of the plowed soil layer, however, these indices during vegetation of winter rape plants range within the optimal values and do not effect greatly the growth and development of winter rape plants. It has been studied that use of different systems of basic tillage for winter rapeseed growing causes redistribution of nutrient substances in the surface soil. Surface and minor tillage slightly increase the content of soluble phosphates, exchange potassium and mineral nitrogen in the soil layer in depth of 0 to 10 cm during winter rape yield period. Owing to the decrease of fuel expenses and non-renuable tillage energy the non-tillage methods allow to decrease general expenditure of the main soil treatment. Effectiveness and bioenergetic estimation of winter rape growing in Prykarpattja conditions on depend from mineral fertilizing system and methods of basic soil tilling are considered. It has been established that for increase of yield and more high level profit and energy outlet it is necessary to put mineral fertilizing at dose N200P70K120 under surface soil tilling. Key words: winter rape, soil treatment, fertilizers, fertility, crop, productivity, weed density, technological qualities of rapeseed.
