During the picking period (breaks) the mushrooms were twisted out before the veil broke and the following data were recorded daily,
corresponding with the work of ˙Ilbay and A˘gao˘glu (1996): Number of mushrooms per bag; yield (g/bag); average cap weight (g/mushroom); average cap diameter (mm); average stalk weight (g/mushroom); average stalk diameter (mm); average stalk length (mm).
