Changes in some soil chemical properties, growth, and yield of cucumber (Cucumis sativus L) are caused by Trichoderma reesei and Trichoderma longibrachiatum in different land-use systems

The study investigated the growth-promotion effects of indigenous Trichoderma species, specifically Trichoderma reesei and Trichoderma longibrachiatum, on cucumber (Cucumis sativus L) yield parameters and soil chemical properties across different land uses. The aim was to assess the growth-promoting abilities of these Trichoderma species, both individually and in combination, in various land use systems. The land uses considered in the study included cultivated land (CL), forest land (FL), and developed area (DA). Soil samples were collected at a depth of 0-30 cm and the results demonstrated a significant increase (p < 0.05) in yield parameters, such as leaf area and overall yield, alongside improved soil properties, including pH, total nitrogen, organic carbon, and essential minerals. The combined application of both Trichoderma species notably enhanced cucumber yields, and improved soil chemical properties compared to the control group. These findings suggest the potential for developing effective bio-stimulants and highlight the important roles of fungal characteristics and soil quality.
