# From waste to wealth: effects of nine agroforestry wastes on Stropharia’s traits & yield

## TL;DR

This study explores using agricultural and forestry waste to grow Stropharia mushrooms, finding that certain materials like fig branches yield the best results.

## Contribution

The paper introduces nine new agroforestry waste substrates for Stropharia cultivation, identifying optimal materials for yield and profitability.

## Key findings

- Fig branches produced the highest quality and yield of mushrooms with a 16.5% grade A fruiting body rate and 5.11 kg/m² total yield.
- Grape stumps, pear, and peach branches also showed good yields of 5.38, 4.64, and 4.62 kg/m² respectively.
- Willow and crape myrtle branches had lower quality fruiting bodies, suggesting they are less suitable for cultivation.

## Abstract

To broaden Stropharia rugosoannulata cultivation substrates, nine agricultural/forestry wastes were tested, evaluating fruiting body count, weight, and total yield, with factors influencing yield also investigated. Fig branches performed best: 16.5 % grade A fruiting bodies, 5.11 kg/m2 total yield, and 232,000 yuan/hm2 net profit. Grape stumps, pear and peach branches were also suitable, with yields 5.38, 4.64, 4.62 kg/m2 respectively. Waste sawdust had 16.2 % grade A but limited economic benefits. Willow branches (9.5 % grade A), crape myrtle branches (8.4 %), soybean stalks (12.5 %), and corn stalks (4.04 kg/m2 total yield) were suboptimal, needing reduced use. Correlation analysis showed first harvest reflects suitability; high lignocellulose materials enhance individual mushroom quality.
