Evaluating on possibility use of pistachio waste in composition substrate of white button mushroom

The white button mushroom is the world’s most widely grown culture mushroom species, that can utilize various kinds of agro industrial lingo-cellulosic waste as a substrate. selection of compost components in each region is essential factor for production of mushrooms. The objective of this study was to evaluate application of pistachio waste by utilizing as a substrate component for button mushroom production and their effects on the quality and quantity of produced mashrooms in 2013, at Tarbiat Modarres University. In this study one control (without waste), pistachio hull and shells mixed (ratio 50:50) (PH), pistachio shelling waste (PSW) and pistachio hulls (PH) were applied in three levels consisting of 25, 50 and %75 combined with substrate control in completely randomized design with four replications (40 experimental units). The results of experiments indicates that the highest yield and biological efficiency percentage was obtained from 25 and %50 of PH and PSW, that the mushrooms production on this experimental substrates were more prolific than of the control substrate. In this experiment, it was found that production of substrate with the PH in compared to the control, is not suitable to yield and biological efficiency percentage.This study demonstrated that Agaricus bisporus may successfully produce from compost containing pistachio waste.
