This research thesis investigates the impact of different weed management strategies, including lemongrass mulch, atrazine, and tembotrione, in conjunction with biodegradable polythene mulch, on the growth, yield, and quality of crops. The study was conducted to evaluate how these treatments influence various agronomic parameters such as plant height, leaf area, chlorophyll content, root length, dry matter production, grain yield, stover yield, and economic returns.
The experimental design included a comparative analysis of these treatments to understand their effectiveness in enhancing plant growth and optimizing yield. The results demonstrated that the integration of lemongrass mulch with atrazine and tembotrione, along with the use of biodegradable polythene mulch, significantly improved key growth indicators and yield parameters. Specifically, plants under these treatments exhibited increased height, enhanced leaf area, and superior chlorophyll content. Furthermore, these treatments contributed to higher dry matter production, improved root development, and increased grain and stover yields.
The study also highlighted the beneficial effects of lemongrass mulch on soil organic carbon content, indicating potential long-term improvements in soil health and fertility. Weed control was notably more effective with these treatments, reducing competition for resources and enhancing crop productivity. The findings suggest that combining organic mulches with selective herbicides and biodegradable materials offers a sustainable approach to crop management, maximizing both yield and economic returns. This research provides valuable insights for farmers and agricultural practitioners seeking to enhance crop performance while promoting sustainable farming practices.
