THE RELATIONSHIP BETWEEN
PRIMORDIA FORMATION AND YIELD
The importance of the primordia formation period can not be over-emphasized. For maximum
yields an optimum number of pinheads must be set, matured and brought to harvest. Certain relationships exist between the pinning process and yields. These are:
1.

During the primordia formation period, pinheads for the first and second flush
are being generated. The second flush primordia are present as thickened mycelial knots

which develop after the first flush is harvested. Once the first flush is off the beds, the second
set of primordia begin to enlarge and within days attain button size. Because 60-75% of the
total yield is normally harvested from the first two flushes, the few days of pinhead initiation
are the most critical in the growing of mushrooms. Hence, all environmental factors must
be carefully monitored to insure the best possible pin-set.
