Summary. Results researching influence of combination of such factors as basic and pre-sowing soil treatment, applting mixture of biopreparations Azotovit and Fosfatovit on weeds dissemination, defeat by root rot and productivity of winter rye are presented in the article. Researches were conducted in seven-field crop rotation on sod-podzolic loamy soil in 2011-2013. Economy and energy estimations of efficiency of technologies of winter rye cultivation including different factors are stidied. Differences in methods had no influence on weeds dissemination; middle negative significant correlation is pointed out between number of weeds and winter rye productivity (r=-0.31). Aplying biopreparations into soil had much more pronounced effect on defeat of winter rye by root rot than spraying plants; ways of soil tillage had not significant influence, there was middle negative significant correlation between productivity and weeds dissemination (r=-0.45). The methods of basic and pre-sowing soil treatment had not significant effect on plant productivity but increasing in productivity in variants applying biopreparations into soil was defined – at 0.15 t-ha, during vegetation – at 0.11 t-ha. Decreasing of costs while main soil treatment is 22.7% with replacing plough with subsurface cultivator; while pre-sowing soil treatment – 45.7% with using combined aggregate conducting operation on input of mineral fertilizers, soil tillage and sowing at the same time. Use of cultivator КBM-4.2 and combined aggregate АPPN-2.1 on subsurface cultivation with input of biopreparations provides profitability at the level of 75-78% with total viability of 1 ton of winter rye grain equal to 3377-3435 rub.
Keywords: combined aggregates, azotovit, fosfatovit, weeds dissemination, root rot, energy and economy efficiency.
