Substrate Preparation: Source local materials (sugarcane bagasse, straw) for cost-effective mushroom growing substrates

In Mauritius, where agriculture is a significant part of the economy, sourcing local materials for mushroom cultivation can be both cost-effective and sustainable. Substrate preparation is a critical step in mushroom farming, as it directly impacts the yield and quality of the mushrooms. One of the most accessible and affordable materials available locally is sugarcane bagasse, a byproduct of the sugarcane industry. Sugarcane bagasse is rich in cellulose and lignin, making it an excellent base for mushroom substrates. To source this material, farmers can collaborate with local sugar mills or sugarcane processing plants, which often have bagasse in abundance. It is essential to ensure that the bagasse is properly dried and free from contaminants before use. This can be achieved by spreading it out in a well-ventilated area to air-dry or using a mechanical dryer if available.

Another locally available material ideal for mushroom substrates is straw, particularly rice or wheat straw. Straw is lightweight, easy to handle, and provides good aeration, which is crucial for mushroom mycelium growth. Farmers can source straw from local rice or wheat fields after the harvest season. When collecting straw, it is important to choose material that is clean, free from mold, and not overly decomposed. Straw should be chopped into smaller pieces (2-4 cm in length) to increase its surface area and improve colonization by the mushroom mycelium. Both sugarcane bagasse and straw can be used individually or in combination, depending on the mushroom species being cultivated and the desired substrate composition.

Once the materials are sourced, the next step is substrate sterilization or pasteurization to eliminate competing microorganisms. For small-scale operations, pasteurization is often more practical and cost-effective than sterilization. To pasteurize, mix the chopped straw or bagasse with water to achieve a moisture content of 60-70%. Then, heat the mixture in a large container or drum to a temperature of 65-70°C for 1-2 hours. This process kills most harmful bacteria and fungi while preserving beneficial microorganisms. After pasteurization, allow the substrate to cool to room temperature before inoculating it with mushroom spawn.

For farmers in AREU, Mauritius, combining sugarcane bagasse and straw can create a balanced substrate that is both nutrient-rich and structurally supportive. A common recipe involves mixing 70% sugarcane bagasse with 30% straw, ensuring a good blend of carbon and nitrogen sources.
