Fertilizer inputs, crop yields, the composition of technological operations and intensity of treatment with different types of pesticides in both basic approaches were evaluated. A comprehensive comparison of impacts showed that all crops, except sugar beet, achieved better economic and emission parameters of production based on the evaluation of GHG production by using reduced tillage compared to ploughing. The total reduction of GHG emissions based on CO2eq on average of all crops per ton as a result of the technological processes was 6% using reduced tillage. The most significant CO2eq reductions were achieved for rye and oat (13%), and spring barley (8%). The reduction of crop yields ranges from about 1% (spring barley) to 4% (grain maize). Cost reduction per tone was in the range of 14% (rye) to 2% (silage maize). The energy gain was at reduced tillage improved at poppy (8%), rape (4%), oat (3%), rye (3%) and spring and winter barley (2%). From the evaluation of the number of chemical protections, a lower number of total protections was found at the no-till system for most crops. In most cases, there was no difference between ploughing and reduced tillage. There was an increase in specific nitrogen consumption per tonne of production in marginal areas, reduced tillage led to an increase in soil compaction.
