Studies were conducted to find out the suitability of saw dusts as potential substrates for cultivation of P.citrinopileatus at Gandhigram Rural Universiy,Gandhigram, Tamilnadu, India. Performance of five saw dusts namely padak,silver oak,pine ,coconut were evaluated by using of them in combination with paddy straw in 1:1 ratio.The study revealed that mushroom species namely P.citrinopileatus could be successfully grown on the silver oak during presummer season.Though faster rate of spawn run,pinhead intiation and harvesting periods were recorded in paddy straw ,maximum yield of mushroom was obtained on silver oak.The results indicate that silver oak saw dust which is cheaper and available in plenty in saw mills,can be utilized successfully as promosing substrate for the commercial cultivation of oyster mushrooms.
