Yur, M.
In this study, the effects of conventional, reduced and no-till cultivation systems with chisel-tillage and no chisel-tillage on soil moisture, soil penetration and Root Length Density in barley over two years in Sandy-Clay-Loam soil texture in Van province.The experiment was utilized a split-split-plot experimental design, a randomized block with three replications. Chisel-tillage and no chisel-tillage were applied to the main plots. Four different cultivation systems (conventional, reduced-I, reduced-II and no-till) were sub-plots. In the study, water soil content (WSC) and soil penetration resistance (PR) were measured in the pre-sowing, the stem elongation, and the heading periods. While WSC was measured at 0-20 cm and 20-40 cm soil depths, PR was measured at 10, 20, 30 and 40 cm depth in each period. Root Length Density (RLD) was only taken at 0-20 cm soil depth after harvesting. Days to heading, plant height, spike length, thousand kernel weight, total yield, grain yield, and harvest index were determined during the development and the post-harvest periods of the barley. It was concluded that chisel application increased yield and yield components due to the positive effect on the PR, WSC and the RLD. However conventional tillage system and redused-I system was in the same group for WSC in some components and some development periods.
