An experiment was conducted to evaluate paddy straw and other locally available substrates for production of straw mushroom (Volvariella volvacea) in Odisha under semi-compost method. Paddy straw (uncrumpled / hand threshed / bundled), when semi-composted, sustained significantly higher mushroom yield (15.63% BE) compared to the yield (11.50 % BE) obtained from its un-decomposed state in traditional method of cultivation. When other wastes such as cotton waste, banana leaves and water hyacinth were mixed with un-crumpled straw, the biological efficiency increased further (16.06 -19.29 % BE). Paddy straw mixed with cotton waste (3:1, w/w) sustained the highest yield potential (19.29 % BE). It was also recorded that semi composted crumpled/ cattle threshed paddy straw (12.0 % BE) was statistically at par with the non-composted uncrupmled/ hand threshed paddy straw (11.50 % BE) in supporting the mushroom yield. The results can be highly rewarding considering that these were traditionally been poor mushroom substrates and there is a rising accumulation of cut pieces of straw due to the increasing use of combined harvester in paddy crop in recent times.
