The growing request for shallots, driven by increasing consumer needs, has not been matched by stable production levels. This study investigated the effects of the application of poultry waste and coconut shell biochar on shallot growth and production. Two factors were evaluated, including poultry waste with various doses of 0, 10, 20, and 30 tons/ha and coconut shell biochar with diverse doses of 0, 10, 20, and 30 tons/ha, with three replications for each treatment. Duncan Multiple Range test at a 5% significance level was performed for the statistical analysis. The yields indicated that giving 30 tons/ha of poultry waste significantly enhanced plant length and bulb count per plant. Additionally, 1The giving of 10 tons/ha of biochar significantly improved plant length, leaf number, wet bulb weight per sample, dry bulb weight per sample, and wet bulb weight per plot. However, the combination of poultry waste and coconut shell biochar did not yield significant improvements in shallot growth and production. This study highlights the potential of poultry waste and biochar as effective soil amendments for shallot cultivation while also noting the limited impact of their combined application.
