Abstract

The present study was conducted to standardize the spawn production and cultivation technology of Agrocybe aegerita, Black poplar mushroom. The mushroom culture procured was grown in Malt Agar (MA) medium and the culture was preserved in MA slants. The slant mushroom culture was used for the production of mushroom spawn. White sorghum seeds were used as a substrate to produce mushroom spawn. The quality spawn produced after complete mycelium spreading was used for the cultivation of mushroom in the mushroom cultivation chamber. The paddy straw substrate was supplemented with various amendments and the potency of each supplement in growth and yield of mushroom were studied. The various steps involved in the cultivation process was repeated and standardized for the optimum production of fruiting bodies with paddy straw as the substrate. The mushroom beds were monitored for their growth and fruiting bodies were harvested. The result indicated the rice bran supplementation of 10% to the paddy straw gave the maximum yield and bio efficiency in par with other supplements.
