Space-intensive agricultural production such as those thing using containerized low-cost growing media could provide income and food to those urban poor who have limited opportunities for livelihood. A container set-up with soil was used to determine the effects of compost with microbial inoculation on the growth of mungbean and pechay. Compost prepared from coconut coir dust-chicken manure mixture was inoculated with nitrogen-fixing bacteria (Azotobacter sp.) and/or cellulolytic fungi (Trichoderma harzianum), incubated for 7 days, and applied in potted mungbean plants at 5g/pot and grown for 30 days. Mungbean (Vigna radiata L. Wilckzek) supplied with uninoculated compost had the lowest fresh biomass and the lowest number of nodules. Compost with combined inoculation of Azotobacter sp. and T. harzianum (each added into compost at 0.5%, w/w) significantly effected the highest plant fresh biomass and number of nodules. The same treatments gave similar results for plant growth and yield levels in pechay (Brassica napus L.) The inoculated compost in this study could thus help reduce the use of chemical fertilizers and promote container growing for urban agriculture.
