The study was conducted to show the effect of the varying combination of volcanic ash and industrial wastes (sawdust and sugarcane bagasse) on the growth of Brassica chinensis Linn. known as pechay. Pechay (Brassica chinensis Linne) was planted in different decomposed concentrations of volcanic ash and industrial wastes using the following ratio combinations: 3:1, 1:1, 1:3, 1:2, 2:1, 2:3, 3:2. There were two control groups namely: pure ash and pure soil. Among the parameters that were determined were leaf area (cm2), fresh weight (g) and dry weight (g) of leaves and petiole, plant nutrients (NPK) and chlorophyll content. Treatments with varying concentrations of volcanic ash and industrial wastes were the better substrate compared to the controls for the growth of pechay. Treatment 3 was found to be the best substrate for pechay in terms of its leaf mean area (72.45 cm2), mean fresh weight (79.95 g), mean dry weight (4.225 g), mean nitrogen (0.592 percent), mean phosphorus (0.09 percent), and mean potassium (0.225 percent) and also mean chlorophyll content (3.214 mg chlorophyll// g fresh weight sample). The treatment groups were significantly different from the control group using ANOVA in completely randomized design and Duncan's Multiple Range Test at 0.05 level.
