Effects of tillage systems on maize yield and porosity of the irrigated chernozem ploughing layer

Type: article
Abstract: With the aim to create favorable conditions for the plant development, the studies on effects of different tillage systems on maize yield and porosity changes of the irrigated chernozem ploughing layer were performed. The objective of the studies was conventional tillage (disc harrow, plough, seedbed conditioner), reduced tillage (rotary shredder) and direct drilling (direct drill seeder). The analysis of variance performed for the yield shows significant differences among observed tillage systems carried out on chernozem. The highest yield of 12.39 t·ha-1 was obtained by conventional tillage. Yields obtained by reduced tillage and direct drilling were lower and amounted to 11.03 t·ha-1 and 10.03 t·ha-1, respectively. The conventional tillage system provided the most favorable porosity with the average value of 51.08%. With no statistical significant differences, the porous to solid phase ratio was somewhat less favorable in soil tilled by the rotary shredder (50.47 vol.%), while it was significantly lower in the variant of direct drilling (48.12 vol.%).
