IMPACT OF TILLAGE AFTER WINTER WHEAT HARVEST ON SOIL AGROPHYSICAL CHARACTERISTICS
After harvesting autumnal wheat, cultivation wasdone in different periods and methods, coming to the end of vegetation period when agrophysics features of soil is analyzed,there an increase in bulk density of soil was seen in the 1st and 2 nd treatment where summer cultivation was done within 28–30 sm depth with and without irrigation. When comparing to the 3 rd treatment where cultivation was within 28–30 sm depth by plantingrepeating crop after autumnal wheat and the cultivation was taken at the same level in the next autumn, bulk density was decreased by 0.04–0.03 gr/sm3 in the cultivation depth (0–30 sm) and 0.03–0.02 gr/sm3 in the under cultivation depth (30–50 sm). Similarly, cavity was identified to be increased by 1.0–1.1% in the cultivation depth (0–30 sm) and 1.0–0.7% in the under cultivation depth (30–50 sm). Comparing the 3 rd treatment where cultivation was done in 28–30 sm depth in autumn after harvesting autumnal wheat then cultivation in 28–30 sm depth after that planting repeating crops and taking its harvest to some treatments where the cultivation in 28–30 sm depth with and without irrigation after harvesting autumnal wheat, cotton yield was taken by 3.1–4.8 centner per hectare more and the total yield was 28.1–31.1 centner per hectare.
