This study aims to evaluate the effectiveness of various soil preparation tools in influencing soil structure and plant development. Conducted during the 2015/2016 crop year at the Central Farm of the National High School of Agronomy, the research analyzed the impact of three agricultural tool chains: deep plowing, agronomic plowing, and no-till methods, on the establishment of durum wheat. Results indicated significant effects on soil moisture, porosity, and cone index, with deep plowing offering advantages in moisture retention and soil penetration resistance. Root density was enhanced in deeply plowed plots, while root diameter was optimal in no-till plots. Root elongation was most pronounced in agronomic plowing. The study concluded that root length and development are strongly influenced by soil parameters.
