Title: Studies on Casing Soil Media during the Cultivation of Agaricus bisporus
Author: T.R. Shandilya
Sphagnum peat/Irish peat have been used for casing in U. K. However, in other mushroom producing countries a variety of casing materials are being used. Bels-Koning (1950) used marl and mixture of soil from garden and peat. Stoller (1952) pointed out the potentiality of peat from Minnesota. Edwards and Flegg (1953a, b) successfully used vermiculite, peat, sand and local soil and recommended the use of sphagnum peat as standard casing in England. Later Nair (1977) has mentioned the use of spent compost as a casing after the removal of the salts from the material, whereas Hayes et al., (1978) have developed PPMB (paper pulp mill by-product) for casing mushroom beds in U. K. Recently Shandilya and Agarwala (1983) have found the combination of F.Y.M. (Farmyard manure) and three years old spent compost mixture equally good for casing as compared to farmyard manure and loam soil combination recommended by Hayes and Shandilya (1977).
When mushroom growing was started in India Mantel (1973) recommended the use of one year old spent compost. Hayes et al., (1976) reported a number of irregularities during crop production with one year old spent compost. The flushes were in patches and there was a high salt concentration. Hayes and Shandilya (1977) recommended F.Y.M. + loam soil (1:1, v/v) as a standard casing in India. Since loam soil is not available everywhere Shandilya (1978) suggested that farmyard manure even if used alone was equally good. In India the research has been confined only to the development of substrates for casing and it was only during the past few years that emphasis have been laid on some important factors pertaining to casing research and results are reported here.Please login to download the PDF for this proceeding.
