Impact of sulphur and micronutrient supplementation on growth, yield, and chemical composition of garlic (Allium sativum L.)

Abstract

Garlic (Allium sativum L.) is a sulfur-rich bulb crop valued for its flavor, nutritional composition, and medicinal properties. This study examined the effect of different sulfur levels and micronutrient supplementation on growth, yield, and biochemical composition. The experiment, arranged in a factorial randomized block design with four sulfur levels (0, 15, 30, and 45 kg S ha⁻¹) and three micronutrient treatments (Control, Zn 5 kg ha⁻¹, B 1 kg ha⁻¹), revealed that 30 kg S ha⁻¹ combined with boron maximized yield (12.2 t ha⁻¹) and biochemical richness.
