Abstract:
To evaluate the influence of different tillage systems on various soil parameters, the behaviour of the yield and the quality of the harvest products for different crops, a long-term field trial was begun in 1996 at the experimental station of the University of Natural Resources and Life Sciences, Vienna, in Groß-Enzersdorf. The field trial has been designed as a split-plot facility with five different tillage systems, two different crop rotations and four repetitions. The tillage systems investigated were conventional tillage, no tillage, reduced tillage, minimum tillage and combined-integrated tillage. The humus content, penetration resistance, the yield as well as the fuel consumption and the working time requirements were compared and evaluated. The humus content varied significantly between the tillage systems. The tillage systems without plough showed a humus accumulation in the top soil (0 to 15 cm depth). With all crops, the penetration resistance of the top soil was the highest with no tillage. For the variants with higher tillage depth, the penetration resistance was greater at a depth of 15 to 25 cm. The yield of sugar beet and grain maize showed no significant differences between the tillage systems. For durum wheat, there were significant differences in the yield between the use of conventional and combined-integrated tillage. The no tillage system differed from all other variants. For winter wheat, the no tillage system differed from all other variants. The results show a significant influence of the tillage system on fuel consumption. The determining factors were the tillage depth and the number of work processes. The working time requirement depended on the number of work processes as well as the size and shape of the field. The working time requirement also rose with increasing intensity of tillage.
