This study aimed to analyze and compare total nitrogen levels and soil pH at two chili cultivation sites at the IP2MP Gurgur Experimental Garden, Tampahan District, North Sumatra. Sampling was conducted purposively at two different locations: the center of the field with wilted chili plants and the surrounding area with normally growing plants. Total nitrogen levels were analyzed using the Kjeldahl method, while soil pH was measured using electrometry. The results showed that total nitrogen levels at site 1 were 0.20% (low), while at site 2 they were 0.26% (moderate). The soil pH at site 1 was 7.56 (neutral to slightly alkaline) and at site 2 it was 7.95 (alkaline). These differences in nitrogen levels and soil pH affected chili plant growth, with plants at site 2 showing better growth than those at site 1. Variations in nitrogen levels and soil pH are important factors influencing chili plant growth, necessitating proper soil fertility management to increase land productivity.
