摘要

The water hyacinth (WH) is a highly invasive aquatic weed that has infested Lake Tana and other freshwater bodies in Ethiopia, creating serious environmental and socio-economic problems. This study was conducted to evaluate the potential effect of vermicompost (VC) derived from WH and cow manure as an organic fertilizer for tomato (Solanum lycopersicum L.) production. A field experiment was laid out in a randomized complete block design (RCBD) with three replications. Six treatments were tested: 10 t ha⁻¹ VC, 5 t ha⁻¹ VC, 2.5 t ha⁻¹ VC + 10% recommended dose of fertilizer (RDF), 2.5 t ha⁻¹ VC + 5% RDF, 100% RDF, and a control (no input). The results showed that the application of WH-based vermicompost significantly improved different growth and yield parameters of tomato, including stem length, stem diameter, number of branches, leaf area, fruit number, fruit weight, fruit length, and fruit diameter. The highest values in growth performance and fruit production were observed in plots treated with 10 t ha⁻¹ VC compared to both the control and RDF treatments. Furthermore, the use of this organic amendment enhanced tomato fruit quality and soil fertility, suggesting its dual role in agricultural improvement and weed management. Therefore, WH vermicompost offers a sustainable, eco-friendly, and cost-effective alternative to chemical fertilizers in tomato cultivation, while contributing to the control of invasive aquatic weeds in Lake Tana.
