This research investigated the effect of mature compost from cassava pulp and swine manure on soil chemical characteristics and growing greenhouse plants i.e., morning glory, Chinese cabbage and Chinese kale. Mature compost with an initial C/N ratio of 30/1 seeded with microbial activator p.d.1 was used in this study. Results revealed that compost in both ground and pelletized forms improved soil quality as indicated by significant increases in TOC content and macronutrients (NO-3-N, available P, and K2O) in soil added with compost compared to control (no compost applied). Plants could use compost in ground form better than pelletized form in which ground compost added at 15.63 ton/ha was the most suitable in growing morning glory, Chinese cabbage, and Chinese kale as indicated by the highest shoot dry weight (1.63, 2.16, and 1.33 g/plant, respectively), and plant circumference (0.56, 3.07, and 0.61 cm/plant, respectively) obtained.
