Calcium, magnesium and sulfur have an essential role in vegetable growth and yield quality. This research was conducted to find out the optimal dose of Ca-Mg-S fertilizer for shallot (Allium cepa Aggregatum group) in alluvial soil. The experimental design was a Split Plot Design with three replications. The main plot was two shallot cultivars; 'Bima Curut' and 'Bangkok'. The sub-plot was the dose of Ca-Mg-S which consists of nine combinations. The ranges of the doses were Ca: 0-225 kg ha‑1; Mg: 0-100 kg ha‑1, and S: 0-100 kg ha‑1. The results showed that there were no significant differences between the treatments. 'Bima Curut' and 'Bangkok' showed the same responses to the treatments. Application of Ca-Mg-S fertilizer did not impact the shallot growth, nutrients uptake and shallot yield. The highest bulb yield was achieved by 75 kg Ca ha‑1, 50 kg Mg ha‑1 and 50 kg S ha‑1.
