Effect of supplementing compost with grapeseed meal on Agaricus bisporus production
Abstract
BACKGROUND:
This work assesses the agronomic performance of grapeseed meal, before
and after oil extraction, in nutritional compost supplement when growing
the mushroom species Agaricus bisporus (Lange) Imbach. The
effect of formaldehyde treatment before using this compost is also
considered. Materials were applied at different doses at spawning. Along
with non-supplemented compost, three commercial nutritional supplements
were used as controls.
RESULTS: In
general terms, grapeseed meal performance was similar to that of
commercial delayed-release nutrients, but improved the non-supplemented
compost response. We highlight that grapeseed enhances performance as
larger yields of harvested mushrooms were obtained with greater dry
weight content; however, their protein content was lower. The best
performance was displayed by fresh formaldehyde-treated grapeseed (6000
ppm) when applied to the 10 g kg−1 compost dose.
CONCLUSIONS:
Our findings suggest that grapeseed meal offers a great potential to be
applied on a commercial scale. The addition of grapeseed resulted in an
enhanced performance as shown by the higher number of harvested
mushrooms. The use of grapeseed meal (extracted or non-extracted), a
low-cost ingredient with high levels of carbohydrates, may suppose an
economic profit on the basis of the positive effect of adding carbon in
the mushroom cultivation. Copyright © 2012 Society of Chemical Industry
