Abstract
The present study on the topic of “Studies on different substrates for spawn
production, growth and yield of oyster mushroom (Pleurotus spp.)” was carried out at
Mushroom Research and Training Centre, Department of Plant Pathology, Banda
University of Agriculture and Technology, Banda, Uttar Pradesh during 2023 to 2024. The
three different strain for Pleurotus are used for this experiment are Pleurotus flabellatus
(DMRP-5), Pleurotus sajor-caju (Pl-19) and Pleurotus florida (DMR-136). In case of
spawn production, sorghum grains exhibited the highest growth at 89.55 mm, closely
followed by sorghum (88.88 mm) and pearl millet (86.55 mm) after 240 hrs of inoculation
in Pleurotus flabellatus. Sorghum exhibited the highest growth at 89.93 mm followed by
wheat (87.69 mm) and pearl millet (85.44 mm) in Pleurotus sajor-caju. Sorghum exhibited
the highest growth at 90.00 mm, followed by pearl millet (87.53 mm) and wheat (85.44
mm) in Pleurotus florida. Among seven different media viz. corn meal agar, oat meal agar,
potato dextrose agar, yeast extract mannitol agar, malt extract agar, V8-juice agar and
Czapek dox agar potato dextrose agar media was found best media with 90.00 mm growth
in all three strains of mushroom at 240 hrs of inoculation. Seven different pH evaluated
viz. 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0 for mycelial growth in which pH 7.0 resulted best for
mycelial growth (90.00 mm) of all three strains of Pleurotus spp. at 240 hrs of inoculation.
Six different temperatures viz. 10℃, 15℃, 20℃, 25℃, 30℃ and 35℃ were also
evaluated among which highest mycelial growth of 90.00 mm was resulted at 25℃ in all
three strains of Pleurotus spp. at 240 hrs of inoculation. Twelve different types of
combination were evaluated for mushroom production among them, wheat straw resulted
in least number of days for spwan run, pin head initiation, fruiting body formation and
fruiting body maturity of all three tested Pleurotus spp. Whereas, Paddy straw + Chickpea
straw resulted in maximum yield of 726 g/Kg, 825 g/Kg and 860 g/Kg in Pleurotus
flabellatus, Pleurotus sajor-caju and Pleurotus florida, respectively.
