EFFICIENCY OF PLOUGH AND DISK HARROW AT WINTER WHEAT STUBBLE FIELD TILLAGE

A disk harrow application at winter wheat stubble field tillage is more acceptable than that of a plough if we compare effects (3,80 ha h-1 to 1,53 ha h-1), fuel consumptions (3,83 kg ha-1 to 8,72 kg ha-1) and specific labour consumption (27,15 kWh ha-1 to 67,27 kWh ha-1). Incorporation of plant residues is significantly more even by a plough (tillage depth 13,31 cm averagely) than by a disk harrow (= -8 cm) which affected numerousness and covering of weed species. Considerably higher numerousness of Chenopodium album individuals (5917) was determined by plough cultivation than in a tillage variant by disk harrow (2656) when present species of Echinochloa crus galli were more abundant (4875) and Chenopodium polyspermum (1531). Decay of organic mass (by 14 September of the same year) was more effective by a plough (44%) than by disk harrow (32%) which is in favour of the plough from the technological point of view.A disk harrow application at winter wheat stubble field tillage is more acceptable than that of a plough if we compare effects (3,80 ha h-1 to 1,53 ha h-1), fuel consumptions (3,83 kg ha-1 to 8,72 kg ha-1) and specific labour consumption (27,15 kWh ha-1 to 67,27 kWh ha-1).
