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