EVALUTION THE EFFICIENCY OF REED PLANT (PHRAGMITES AUSTRALIS) WASTES AND AQUEOUS EXTRACT OF LIQUORICES (GLYCYRRHIZA GLABRA) ON THE PRODUCTION OF AGARICUS BISPORUS

Abstract

This study was conducted to evaluate using possibility of common reed plant wastes in the preparation of compost for Agaricus bisporus rather than wheat straw, which was adopted as a basic substrate in the preparation the compost in the world and the effect of Liquorice extract spraying at pin fruit bodies production and its quntity.Results indcate the lower proportion of carbon to nitrogen (C: N Ratio) was 8.51:1 with the compost of wheat straw compared with common reed watse 15.32:1 and 12.32:1 with the compost of the mixture. The best production of fruiting bodies achieved 440.83 g/5 kg with the compost of common reed waste after 21 days of harvest, compared with 371.17 g/5 kg from wheat straw, and that the best biological efficiency of 26.5% achieved with the common reed waste compost, followed by an average of wheat straw the best rate of fruiting bodies weight 46.12 g with the compost of the common reed waste, compared with 25.17 g on control of wheat straw compost, while for a number of fruiting bodies achieved the greatest number of 17.42 fruiting bodies / box with the wheat straw compost, compared with 7.42 fruiting bodies / box from the common reed waste compost. For the quality of fruiting bodies that the highest cap dimater and a longer stipe 55.5 mm and 31.83 mm was obtaind from common reed waste compost compared with 43.08 mm and 31.58 mm from wheat straw. Chemical analysis showed that the best protein content of 20.68% with fruit bodies from the compost of the mixture, compared with 18.27% on fruit bodies from wheat straw. And the highest content of Ortho Dihydric Phenols 9.75 g/kg with the compost of the common reed waste, compared with wheat straw 8.76 g/kg
