Phytosanitory state of sowing of a summer rape at application resource-saving technologies
In article results of researches of 2014 on sod-podzol sandy loam soil of a long-term field experiment in conditions of "Mihajlovsky" enterprise of the Yaroslavl area on an estimation of a role of various on intensity resource-saving systems of soil cultivation, fertilizings and protection of plants in change of indicators of an abundance of weeds in sowing of a summer rape on a green material are introduced. It is established that is more expedient to use a combination of processings - surface-mouldboard system on an extensive background of a feed both without herbicides, and in case of their after-action. Thus regularity of reception of productivity of a summer rape being not lower than at annual mouldboard processing is traced, simultaneously with economy for its implementation. However, the further minimisation of system of the basic soil cultivation (to annual surface processing) does not provide adequate positive efficiency on productivity owing to deterioration of phytosanitory conditions of an agrophytocenosisis.
