Abstract
The studies to evaluate different substrates for spawn production and commercial cultivation of Golden Oyster Mushroom Pleurotus citrinopileatus were held at Wadura during the year 2021. Seven commonly available substrates namely, barley grains, maize grains, Oat grains, bajra grains, broad beans grain, almond shells and wheat grains (check) were used to evaluate for their suitability in the production of spawn (Pleurotus citrinopileatus). Results showed that maize grains and barley grains were evidence as more efficient substrates with regards to spawn run and spawn texture. The spawn run in maize grains, barley grains and bajra grains was completed in 10.2, 10.8 and 11.4 days, respectively as compared 12.8 days in wheat grains (check). The spawn colour and textures on different substrate showed slight variation, while the spawn colour ranged from ‘brownish-white’ in walnut shells and almond chips, ‘light brown’ in broad beans to ‘white’ in all other cereal grains substrates, Spawn texture ranged from ‘cottony’ to ‘fluffy’ texture was observed. All substrates were found suitable for spawn preparation of Pleurotus citrinopileatus. Eight different substrates namely, Paddy straw, oats straw, maize husk, common bean straw, apple leaf litter, poplar leaf litter, almond hull and apple pomace were evaluated for cultivation of Pleurotus citrinopileatus. All substrate were varied significantly regarding yield, cost benefit ratio and biological efficiency. Paddy straw was found most efficient substrate producing the highest yield (411.8g) followed by almond hull (330.4g). While lowest yield (126.2g) was recorded in apple pomace. The highest biological efficiency (82.36 %) and substrate to yield ratio (1:2.29) was recorded with paddy straw followed by almond hull where biological efficiency and substrates to yield ratio was (66.08%) and (1:1.96), respectively. The lowest biological efficiency (25.24%) and substrate to yield ratio (1:0.08), was recorded with apple pomace.
