Abstract:
Supplementation to increase the quality and yield of white button mushrooms (
Agaricus
bisporus
) consists o
f the addition of nutrients, particularly proteins, to the compost. In this
study, the effect of
mushroom cultivation on applying a delayed
-
release nutrient
supplement to Phase II composts was evaluated. Two application dosages and composts
with high nitro
gen contents were used. Depending on the compost and supplement dosage
used, increases in biological efficiency ranging between 6.2 and 22.3% were obtained. An
excellent response to supplementation can be obtained even when using composts with
high nitroge
n contents (in our case, 2.45 and 2.61% sms) during spawning. It is
additionally conceivable that the application of supplements to composts with lower N
contents or the application to spawned compost would provide an even better yield,
without adversely a
ffecting the quality of the harvested mushrooms. This practice is of
considerable interest because of the economic benefit.
