Yield Evaluation of Different Strains of Paddy Straw Mushroom (Volvariella spp.)

Paddy straw mushroom (Volvariella volvacea) is an edible mushroom, which has a high demand in Angul district of Odisha due to its taste, aroma and nutritive value. Two species namely OSM- 11 and OSM-12 were experimentally evaluated on treated paddy straw with 2 % lime solution. OSM-11 was observed to perform best with highest productivity in total production in number (51) and weight of (1052.03g). In the present study b o t h O S M - 1 1 a n d O S M - 1 2 w e r e performed better as compared to the f a r m e r s p r a c t i s e d p a d d y s t r a w mushroom. With respect to pin head formation and fructification both the species shows 2-3 days delay than Volvariella volvacea and also delayed harvesting of 1-2 days indicating no significant delay in the duration of the crop raising. The lowest biological and economical yields were found in Volvariella volvaceae (700.45g). The above findings reveal an opportunity for commercial implication of paddy straw mushroom especially for utilization of different strains of paddy straw mushroom.
