Title: Future Development of Mushroom Growing throughout the United States
Authors: P.B. Flegg and J. Smith


In 1974 Vedder and Woltjer discussed in detail the advantages and disadvantages of four of the most important methods of growing agaric mushrooms, namely, the single zone system with shelves, the multiple zone tray system with trays and compact farms with either trays or shelves. They concluded that the ideal method of growing has yet to be found, the choice depending very much on circumstances. To assure future progress, however, they advised that more attention should be given to methods of mushroom growing.

More recently Tschierpe and Hartmann (1977) compared modern mushroom growing methods including the tray system and the shelf system as typified by the Dutch industry.

These two papers reflect the interest among mushroom growers in analysing present growing methods to improve economic efficiency. Tschierpe and Hartmann make the point that, by the law of diminishing returns, dramatic increases in mushroom yield per unit quantity of compost as have been achieved over the past three decades cannot be expected in the future. However, it may be possible to increase the output of mushrooms from a given farm by appropriate developments in growing methods. Our purpose in this paper is to consider how growing methods may develop in the future. At the Glasshouse Crops Research Institute one of our research projects is aimed at the development of new methods of growing and thus the thoughts expressed here form a base from which this project may develop and, hopefully, may stimulate others either to follow up some of our suggestions or produce ideas of their own.
