Yardlong bean is a strategic food commodity that can be cultivated in polybags and is widely consumed by the Indonesian population. One important factor in cultivating yardlong beans is the planting media and fertilization. However, the price of inorganic fertilizers has been increasing year by year. Additionally, there is a problem of baglog waste generated from oyster mushroom cultivation, which amounts to approximately 1 ton and is left to decompose over a period of 3-4 months. Furthermore, baglog waste, which is made from wood powder, contains nutrients such as total N 0.6%, P 0.7%, K 0.02%, and organic C 49.00%, which can improve soil fertility. Therefore, one way to utilize baglog waste and reduce the use of inorganic fertilizers is by using it as a planting medium. However, the C/N ratio of baglog waste is relatively high, so additional nitrogen sources are needed to achieve a low C/N ratio. One material that can be used as a nitrogen source is chicken, goat, and cow manure through composting process. This study aims to determine the effectiveness of compost made from baglog waste as a planting medium with the addition of chicken, cow, and goat manure on the growth and biomass production of yardlong bean (Vigna sinensis L.) plants using a Completely Randomized Design (CRD) with 4 treatments: MKo = 7 kg baglog waste; MKa = 5 kg baglog waste + 2 kg chicken manure; MKs = 5 kg baglog waste + 2 kg cow manure; MKk = 5 kg baglog waste + 2 kg goat manure. The data were analyzed using ANOVA and Duncan's Multiple Range Test. The results of the study showed that the MKa treatment (baglog waste + chicken manure) yielded the best results in terms of vegetative, generative, and production parameters. The vegetative parameters showed that the MKa treatment (baglog waste + chicken manure) had the highest plant height and leaf number, significantly different from other treatments. The generative parameters indicated that the MKa treatment (baglog waste + chicken manure) had the best results in terms of flowering age, significantly different from other treatments, while there were no significant differences in fruit weight, fruit length, fruit number, shoot-to-root ratio, and moisture content
