Özet
In this study, field cultivator (FC), disk harrow (HD), combination of cultivator with spring teeth and rotary harrow (CS+RH) were used as secondary tillage equipment in spring. Physical properties of soil such as bulk density, porosity, mean weight diameter and aggregate stability were determined before and after tillage. Moreover, effect of different seedbed preparation techniques on yield of sunflower was also investigated. In the result of the study, differentiations among the secondary tillage equipment were observed due to bulk density and porosity. Small sized aggregates (1-5mm) were highly in tillage with combination of cultivator with spring teeth and rotary harrow. While the mean weight diameter, which shows the durability of aggregates to water, was 2.83 mm before tillage, it was 3.96 mm in tillage with DH, 1.80 mm in tillage with FC and 2.50 mm in tillage with combination equipment. Although the mean weight diameter in tillage with DH increased, decreased in tillage with FC. The best aggregate stability obtained from seedbed preparation by disc harrow. On the other hand field cultivator is the most affective soil embossing tool while the cultivator with spring teeth rotary harrow combination is smashing. The yield values were found 2.002 Mg ha(-1) with DH, 2.106 Mg ha(-1) with FC, 2.175 Mg ha(-1) with CS+RH.
