This study aims to obtain certain doses of huma-fulvic acid and slow release
compound fertilizers that can increase the growth and yield of shallots. This
research was conducted in the experimental field of the Faculty of Agriculture,
University of Muhammadiyah Purwokerto, from August to October 2022. The
research method used a completely randomized factorial design with two factors,
namely the dose of humic-fulvic acid (without humic-fulvic acid, 250 ml humic
acid / polybag) and slow release compound fertilizer (without compound fertilizer,
0.45 gram compound fertilizer per polybag). Parameters observed were total leaf
length, number of leaves, fresh weight of leaves, fresh weight of tubers, number of
tubers. The results showed that the dose of humic-fulvic acid had a significant
effect on the parameter number of leaves aged 32 hst. The application of slow
release compound fertilizer had a significant effect on the total parameter of leaf
length at 64 hst. The interaction between humic-fulvic acid doses and slow release
compound fertilizer had no significant effect on all observed parameters.
