EFFECTS OF DIFFERENT TILLAGE METHODS ON SOIL COMPACTION AND SOME PROPERTIES IN WHEAT

This study focuses on the effects of different tillage methods on plant and soil properties in wheat after the second product corn. Conventional tillage (CT), reduced tillage (RT) and zero tillage (ZT) were used as soil tillage methods. In terms of average moisture values, ZT (24.5%) had the highest value while CT had the lowest (21.9%). Values close to each other were obtained for plant heights ( CT (85.6 cm), RT (84.6 cm), ZT (83.6 cm)). In terms of yield characteristics, higher values were obtained for the number of grains per spike ZT (50) and for the weight of 1000 grains ZT (48 g). Penetration resistances were measured at a depth of 0-50 cm in the soil at 5 cm gaps in the sprouting of the wheat, stem forming and the post-harvest periods. Overall, it was observed that the penetration resistance increased with increasing depth. However, it was also observed that the resistance in CT was lower in the upper part of the soil and the penetration resistance increased mainly after 40 cm due to the formation of the plow base. Taking into account all the results obtained, the study showed that conservation tillage should be adopted and applied by farmers due to its eco-friendliness, economic efficiency, positive effects on the soil, and so on.
