| Conservation tillage (including no-till and reduced tillage) is one of the main components of conservation agriculture, which initially helps improve soil physical indicators by reducing soil erosion and preserving plant residues. Increasing soil grain stability, permeability and porosity, reducing evaporation and maintaining soil moisture, and protecting against water and wind erosion are among the long-term effects of conservation tillage. This tillage system also has a positive effect on soil quality indicators such as organic carbon, organic matter, nutrient supply, and cation exchange capacity. Considering the other issues mentioned and the need to maintain soil quality as a main component in sustainable agriculture, this experiment was conducted with the aim of investigating the effect of different tillage methods and the use of plant residues on some physiological characteristics of triticale (X Triticosecale Wittmack) and soil chemical and biological indices in the climatic conditions of Ahvaz in The experiment was carried out in split plots based on a randomized complete block design with three replications at Shahid Chamran University of Ahvaz during 2022-2023. The main factor includes different methods of tillage in three levels (conventional tillage, reduced tillage and no tillage) and the sub factor also includes 5 levels of plant residue application (No residues (control), wheat residues, mung bean, sesame and half of wheat residues + half of residues Mung bean) was considered.The results showed that the interaction effect of tillage treatments and the use of plant residues on chl b and SPAD index (p≤0.01).. Also, the interaction of tillage and residue application on microbial mass carbon was significantly (p≤0.05). The interaction study of tillage and residue application effects showed that the highest soil organic matter (1.53%) was from the no-till treatment with wheat residue application. The interaction study of the effects of tillage and residue application also showed that the lowest soil microbial mass carbon (73.25 mg/kg) was obtained from the conventional tillage treatment and no residue application (control) and the highest soil microbial mass carbon (233.2 mg/kg) was obtained from the no-tillage treatment and wheat residue application. |
