ABSTRACT
The present investigations entitled “Studies on cultivation of Pleurotus cornucopiae (Paulet) Rolland
on different agroforestry substrates in Himachal Pradesh” was undertaken to evaluate various cultural
requirements, grain substrate for spawn production and different agroforestry based substrates used for fruit
body production of the test fungus. Out of five solid and liquid media tested, potato dextrose agar and potato
dextrose broth were the best solid and liquid media, respectively and optimum temperature of 250C and pH 7.0
was found to be the best for better mycelial growth of the test fungus. Out of five grain spawn, minimum (7.33
days) time for spawn run was observed on jowar grain spawn and maximum (4.20) number of fruit bodies was
observed in wheat grain spawn. Out of five substrates, minimum (16.30 days) time for spawn run, maximum
(4.40) number of fruit bodies, was observed on wheat straw substrate. So far as morphological characters of P
cornucopiae in different substrates was concerned, longest stipe length (23.92 mm), fruit body length (38.88
mm) and cap diameter (55.96 mm) was observed on wheat straw spawned with wheat grain spawn. Maximum
yield (496.00 g/2kg substrates) was observed on wheat straw substrate spawned with wheat grain spawn.
Biological effeciency of different substrates spawned with five grain spawn, ranged between 16.33 to 82.66 per
cent. Out of five spawn doses, minimum (14.00 days) time for spawn run, maximum yield (517.33 g/2 kg
substrate), maximum number of basidioma (7.33) and good biological efficiency (86.22 %) was recorded in
wheat straw spawned at the rate of 5 per cent. However yield at 5 per cent rate of spawning was statistically at
par with that at 4 per cent rate (507.33 g/2 kg substrate). For the production of P. cornucopiae, wheat straw
proved to be the best substrate exhibiting minimum time for spawn run (16.33 days), maximum number of
basidioma (20.49) and yield (1276 g/5kg substrate) as well as good biological efficiency (85.06%).Out of six
supplements amended in wheat straw substrate evaluated at five different doses for the production of test
mushroom, wheat bran supplemented at the rate of 6 per cent took minimum time for spawn run (12.00 days)
and produced maximum (8.77) number of basidioma with highest yield (546.66 g /2 kg substrate) and good
biological efficiency of 91.11 per cent in comparison to wheat straw supplemented with oat meal exhibiting a
biological efficiency of 74.44 per cent only
