ABSTRACT

The purpose of this research was to evaluate the productiveness, biological efficiency, and fresh and dry biomass of Pleurotus spp. cultivated in elephant-grass-based substrate. Three species of Pleurotus were used: Pleurotus ostreatus (strains BF24 and DF33), P. ostreatoroseus (strain POR01/06), and P. citrinopileatus (strain PAM01/06). Dry and powdered elephant grass was humidified for 24 hours, wrapped in bags, pasteurized at 100°C for 35 minutes, and finally inoculated with 3% spawn. The cultivation period extended for 105 days, encompassing 3 production flushes, and the beginning of the harvest was 25 days after substrate inoculation. P. ostreatoroseus presented the highest productiveness rates (33.16%), biological efficiency (132.64%), and fresh mass (331.60 g); the P. ostreatus strain BF24 presented the highest dry mass rate (31.16 g).
