Studies on effect of seasonal adaptibility, organic additives and substrates on biological efficiency of Pleurotus florida

The investigation on seasonal adaptability on productivity of P. florida revealed that the period from November to February was appropriate for obtaining higher yields in the range of 791.33–796.17g/bag with the corresponding biological efficiency of 79% in the coastal belts of Odisha. Mushroom yields were however, less during rainy and summer seasons. Further, wheat bran at 10% of the dry weight of substrate proved superior among the six organic supplements evaluated in terms of yield (883.33g/bag) and biological efficiency (88.33%). Among seven agro-wastes evaluated for their yield performance, the conventionally used green gram stick was significantly superior in terms of yield (880.50 g/bag) and biological efficiency (88%).
