EFFECT OF SPENT MUSHROOM COMPOST AQUEOUS EXTRACT ON SEED GERMINATION OF SOLANUM LYCOPERCUM AND ABELMOSCHOUS ESCULENTUS

The utilization of agricultural waste as a soil amendment has gained significant attention in recent years due to its potential to improve soil fertility and promote sustainable agricultural practices. This study investigated the properties of spent mushroom compost (SMC) and its aqueous extract's effects on the seed germination of Abelmoschus esculentus (Okra) and Solanum capsicum (Tomato). Spent mushroom substrate (SMS) was composted for 14 days, during which microbiological analysis, physico-chemical parameter assessment, and biochemical tests, including sugar fermentation, were conducted to evaluate its transformation into SMC. The microbiological analysis provided insights into the microbial populations in the compost, while the physico-chemical parameters such as pH, moisture content, and nutrient composition revealed the nutrient enhancement during composting. The biochemical tests confirmed the metabolic activity of the composted material. The aqueous extract of SMC was further analyzed for its impaet on seed germination. Germination trials showed notable differences in germination rates, seed vigor, and early seedling growth between treated and untreated seeds. Abelmoschus esculentus demonstrated a higher tolerance and growth response compared to Solanum capsicum, indicating species-specific interactions with the compost extract. In conclusion, the findings suggest that SMC is a promising organic amendment with potential benefits for seed germination and soil enrichment. This research highlights the dual benefits of waste recycling and agricultural productivity enhancement, contributing to sustainable farming practices.
