Abstract
|
|
|
|
This study was carried out to elucidate suitable supplementary nutrition for Neolentinus lepideus cultivation. The main substrate for cultivation was douglas fir sawdust, and supplementary materials for experiment were corn meal, corn hull, corncob, beet pulp, and potato starch. The higher amount of total nitrogen source was showed in corn meal (0.45%) than any other nutritive materials. Incubation ratio and cultivation period showed the best 97% and the shortest 43 days on medium with corn meal substrate. The fruit body yield and biological efficiency on medium with 10% corn meal were highest 122 g/1 kg and 35%, respectively. Factor analyses concerning fruiting yield showed total nitrogen source (r = 0.95) and crude fat (r = 0.65). These results are recommended that N. lepideus cultivation is corn meal material as the source of the supplementary nutrition and total nitrogen source as the factor of fruiting body yield on the Douglas fir sawdust medium.
