Abstract

Cambodia is an agricultural country that
consistently generates substantial agricultural
waste or residue, including spent mushroom, rice
husk, rice straw, and animal manure. Effectively
managing these waste materials could prove to be
the optimal choice for farmers, enabling them to
reduce production costs and increase income.
Spent oyster mushroom compost, among these
wastes which contains valuable nutrients and also
beneficial microorganisms. Therefore,
investigating its use as a growing medium for Pak
Choi, combined with other agricultural waste
materials, is worth exploring. This experiment
was conducted using a Completely Randomized
Design (CRD) with five growing media
formulations (G1-G5), with G5 designated as the
control, utilizing soil only. After the harvesting,
the results demonstrated that all growing media
incorporating spent oyster mushroom spawn
mixed with other agricultural residues led to
increased Pak Choi yields. However, G2,
consisting of chicken manure, rice husk ash, spent
oyster mushroom compost, and soil in equal
proportions (1:1:1:1), emerged as the most
effective growing medium formulation, as it
consistently yielded higher Pak Choi yields
