  "abstract": "<p>This research examined the effect of various substrate compositions on the growth rate and yield&nbsp;<br>\nperformance of oyster mushroom (Pleurotus ostreatus) under controlled conditions at Woldia&nbsp;<br>\nUniversity, Ethiopia. Given the national need for sustainable, low-input food sources amid&nbsp;<br>\nrising food insecurity, the study addresses a critical gap in knowledge regarding optimal&nbsp;<br>\nsubstrate utilization using locally available materials such as teff straw, grass straw, and&nbsp;<br>\nsawdust. A completely randomized design with seven treatments and three replications was&nbsp;<br>\nemployed. Significant differences (p &lt; 0.05) were found among treatments for key variables&nbsp;<br>\nincluding colonization period, pinhead formation, stipe length, cap diameter, number of fruiting&nbsp;<br>\nbodies, total fresh yield, and biological efficiency. The highest total yield (530.87 g) and&nbsp;<br>\nbiological efficiency (53.09%) were recorded in the substrate mixture of 33.3% teff straw, 33.3%&nbsp;<br>\ngrass straw, and 33.3% sawdust. This treatment also produced the most consistent regrowth&nbsp;<br>\nacross three flushes. In contrast, the 50% sawdust + 50% teff straw treatment yielded the lowest&nbsp;<br>\nbiological efficiency (49.03%). Substrate composition significantly influenced cap diameter&nbsp;<br>\n(ranging from 2.87 to 7.73 cm) and number of fruiting bodies (9&ndash;26 per flush), indicating that&nbsp;<br>\nblended substrates optimize physical structure and nutrient availability. These findings&nbsp;<br>\nunderscore the importance of strategic substrate formulation to enhance mushroom productivity&nbsp;<br>\nand support food security initiatives through cost-effective, environmentally friendly cultivation&nbsp;<br>\nsystems.&nbsp;</p>",
