The paper presents field trials focused on technological and economic comparison of
conventional tillage (CT) and reduced tillage (RT) technologies of soil cultivation and drilling of
winter oilseed rape (Brassica napus L.). During fifteen production years starting in 2001/02, trials
were set up in 520 fields of around 40 farm businesses located in all of the districts of the Czech
Republic. With respect to average seed yields, no significant differences were proved with respect
to tillage systems, to the application of organic fertilizers and to the fertilization during sowing.
Irregular distribution of trial fields into the individual production areas influenced the outcomes
thou. Concerning winter rape seed yields, costs per production unit, and earnings per hectare, the
most suitable production area proved still to be the potatoes one, but particularly over the recent
period also beet production area. The corn production area produced, despite some exceptions,
worst results. Over the fifteen-year time, the average oilseed rape yield of all 520 monitored fields
was 3.72 t ha–1
. Reduced tillage attained average yield of 3.73 t ha–1
, i.e. matched almost exactly
the one of 3.70 t ha–1
attained by conventional tillage. Unit production costs realized by
conventional tillage surpassed by 4.1% those gained by reduced tillage. Related earnings per
hectare were on the other hand lower by 17.0%. With respect to fuel and labour consumption,
reduced tillage brought significant savings reaching in average 20.2%, respectively 24.0%. In
terms of yields, reduced tillage with deeper soil loosening proved repeatedly favourable results.
