Abstract
|
|
|
|
The effects of addition of eggshell to sawdust substrate for the growth of F. velutipes were investigated. Eggshell used in this study contained 20.7% C, 0.81% N, 2530 ppm P₂O_5 and 44.37% Ca. The addition of eggshell resulted in the increase in bulk density and decrease of moisture content of the substrate. The addition of eggshell significantly increased the yield of the mushroom fruitbody. The addition rate of 15% (v/v), by 25% and at the rates of 5% and 10%, about 20%. Although the addition of eggshell to substrate did not improve the quality of mushroom, it increased the number of effective stipes as compared to control plot; approximately 13% more than in the control plot.
