Different methods of cropstand establishment within the system of winter oilseed rape cultivation

摘要

The aim of the study is to assess various technologies of winter oilseed rape cropstand establishment, and to choose those which bring advantages to farmers. In order to check up different alternatives, field trials have been carried out in Oparanysince 1998. The technologies in question are divided into three groups: traditional technologies (ploughing & drilling), minimized technologies (soil loosening & drilling), and finally non-tillage technologies (drilling straight into stubble). The technologies are assessed with respect to direct costs, seed yields and revenues. According to the results, the ploughing operation can apparently be substituted by reduced soil-treatment techniques in the system of oilseed rape cultivation.
