Recycling of spent Pleurotus compost for production of the Agrocybe cylindracea

Abstract

Spent Pleurotus mushroom compost and rubber sawdust were used as a substrate for a cultivation of Agrocybe cylindracea. The five mixed ratios for spawning media were entirely spent mushroom compost, spent mushroom compost and rubber sawdust (ratio 3:1, 1:1 and 1:3 respectively) and entirely rubber sawdust. The comparisons were evaluated on number of days for full colonization of the mycelia, time to first flush, number of basidiocarp and yield on 850 g in plastic bag. The average higher yield of A. cylindracea for the formula spent mushroom compost alone were obtained 135.63 g/bag were not significant different when they were compared with rubber sawdust only yield obtained 56.46 g/bag.
