Abstract
This study was carried out to investigate the effect of several substrates; used rockwool, several spent mushroom composts, and common used media, such as rockwool and vermiculite, on growth and fruit quality of cucumber. Cucumber grew dramatically in the rockwool+peatmoss (1:2 v/v) (RP) and fine granular rockwool in hydroponic system using Yamaztiki's solution for cucumbers. The yield of cucumber fruit was highest in recycled winter mushroom compost (RW), and followed by 100% perlite (Par), recycled oyster mushroom compost (RO), and RR but there was no significant difference among these three media. Soluble solid and firmness were higher in Per and vermiculite (Ver), and any difference was not found among the others. Vitamin C was not influenced by kind of substrate. The results confirm that several reused or recycled substrates have high possibilities for use as medium for hydroponic culture in cucumber.
