Abstract EN

Results of the paddy straw mushroom (psm) V2volvacea and producfion on different substrates showed that the Paddy straw substrate surpassed in extended time for psm mycelium growth completion with 3.25 days, pinheads emergence for 6 days and in fruiting bodies formation emergence for 4.25 days after pinheads stage .meanwhile, mean of psm fruit weight was 110g/2kg substrate weight while bio-efficiency was 23.89%.

stalk length and cap diameter psm were exceeded on corncobs substrate with 5.42 and 7.82cm respectively compared with 3.67 and 7.47cm on paddy straw respectively.

On wheat straw, psm mycelium growth completion, pinheads emergence and fruiting bodies took the longest time with 6.25, 9.25 and 5.75 day after psm pinhead stage2 on wheat straw substrate it was found that stalk length, cap diameter, fruit weight and bio-efficiency means were 2.92 cm, 5.98 cm, 55.5 g/2 kg and 9.31 respectively.

Chemical analysis showed that contain the highest content of moisture and protein percentages with 90.73%and 40.70%respectivily.

Corncob substrate recorded the highest percentage of psm fruit ash with 12.03%.higher fat percentage was found in fruits grown on paddy straw and corn substrate with same percentage, 1.266% for both substrates.

19.36% and 53.93% were the highest percentage of manufactured fiber and carbohydrates were found to be in psm grown on corn cobs substrate and palm waste respectively.
