Abstract

Hed Hu Hnu (Auricularia polytricha) and Hed Khon Khao (Lentinus squarrosulus) were cultivated
on pararubber sawdust supplemented with oil palm kernel meal at different concentrations. Number of days
for full colonization of the mycelia, number of days from expossure to 1^st cropping time, and yield on oil
palm kernel meal were compared to those supplemented with 5% rice bran. Depending on the results it was
suggested that 5% and 15% of oil palm kernel meal was suitable for Hed Hu Hnu and Hed Khon Khao,
respectively. Yield of A. polytricha on 950 g of sawdust + 5% oil palm kernel meal + 1% Ca(OH)₂ was 380.58
g/bag (B.E. = 114.5%), during 90 days of harvesting time. L. squarrosulus needs more than 5% of oil palm
kernel meal to support the higher yield. Cultivation of L. squarrosulus on 950 g of sawdust + 15% oil palm
kernel meal + 1% Ca(OH)₂ yielded 123.72 g/bag of basidiocarps (B.E = 37.2%), during 60 days of harvesting time.
