Pengaruh Beberapa Dosis Nitrogen Terhadap Pertumbuhan Dan Produksi Bawang Daun (Allium Fistulosum L.)

---

ABSTRACT
Welsh onion (Allium fistulosum L.) is an important horticultural commodity widely
used as a culinary ingredient. One of the main challenges in its cultivation is the
low availability of nitrogen (N) in Inceptisol soil. This study aimed to determine
the effect of various nitrogen doses on the growth and yield of Welsh onion and to
identify the optimal nitrogen dose. The research was conducted at the Experimental
Farm of the Faculty of Agriculture, University of Riau, using a completely
randomized design (CRD) with a single-factor arrangement consisting of five
nitrogen fertilizer treatments (100, 125, 150, 175, and 200 kg.ha⁻ ¹ of urea) and four
replications. The observed parameters included plant height, number of leaves, stem
diameter, leaf diameter, number of tillers, fresh weight, dry weight, and root
volume. The results showed that nitrogen application had a significant effect on
most growth and yield parameters, except for the number of tillers. The application
of 175 kg.ha⁻ ¹ of urea produced the highest values in most parameters but was not
significantly different from the 150 kg.ha⁻ ¹ treatment. The dose of 150 kg.ha⁻ ¹ of
urea was considered the most efficient, as it produced optimal results with more
economical fertilizer use. This nitrogen dose resulted in the best growth and yield
in terms of plant height, number of leaves, leaf diameter, stem diameter, fresh
weight, dry weight, and root volume of Welsh onion.
Keywords: Inceptisols, Urea, Vegetative growth, leaf diameter
