Aplikasi Pupuk Kalium Terhadap Pertumbuhan Dan Produksi Tanaman Bawang Merah (Allium Ascalonicum L.)

---

ABSTRACT
Shallot (Allium ascalonicum L.) is a high-value horticultural crop widely used as a cooking ingredient and for its medicinal properties. However, its cultivation in Riau Province faces challenges due to suboptimal soils like Inceptisols, which are deficient in essential nutrients, particularly potassium (K). This study aimed to examine the effect of potassium fertilizer on the growth and yield of shallots, determine the optimal dosage for maximum production, and analyze correlations between growth parameters. The experiment was conducted at the Experimental Farm of the Faculty of Agriculture, University of Riau, using a completely randomized design with five potassium fertilizer levels (0, 100, 125, 150, and 175 kg K₂O ha⁻¹) and four replications. Observed parameters included plant height, number of leaves, harvest age, bulb number and diameter, fresh and dry bulb weight per clump, and yield per plot. Results showed that potassium significantly affected most growth and yield variables except plant height and harvest age. The highest performance was achieved at 175 kg K₂O ha⁻¹, significantly increasing leaf number, bulb size, and total yield. Furthermore, fresh bulb weight per clump showed strong positive correlations with other yield parameters, indicating potassium's critical role in enhancing shallot productivity in Inceptisol soils.
