Studies on Standardization of Production Technology of Oyster Mushroom

Abstract

In the present investigation, attempts were made to evaluate different substrate quantities to get higherbiological efficiency. Two strains of oyster mushroom (PL-19-05 and PL-19-06) were cultivated by usingdifferent quantities of wheat straw (2 kg, 3 kg, 4 kg and 5 kg). Among four substrate quantities, earlyspawn run (9.50 days and 11.00 days) and pin head initiation (19.25 days and 19.00 days) were observed at2 kg substrate quantity for PL-19-05 and PL-19-06 strains, respectively, followed by 3 kg, 4 kg and 5kgsubstrate quantities. Maximum yield was obtained at 5 kg substrate quantity for both strains. But biologicalefficiency was highest at 3 kg of substrate quantity which was 75.73% and 89.98 % for PL-19-05 and PL-19-06 strains, respectively, increase or decrease in quantity of substrate ensued in low biological efficiency.Based on the results, 3 kg substrate quantity is suggested as optimum substrate quantity forsub-humidconditions of Udaipur region to get higher biological efficiency and easy handling.
