Ultisol is a type of soil formed in the tropics with low pH and relatively low nutrient content. This study aims to determine the effect of the combination of humic acid-biochar and urea fertilizer to increase the availability of N nutrients and the growth and yield of mustard plants (Brassica juncea L.) on ultisol. This research was conducted from September to December 2024 and was conducted at the Plastic House, Department of Soil, Faculty of Agriculture, Sriwijaya University. The experiment was conducted using a Randomized Complete Factorial Design (RALF) with two factors. The first factor was humic acid-biochar with 4 levels and the second factor was Urea fertilizer with 3 levels, each treatment was repeated 3 times, so there were a total of 36 experimental units. The results showed that the application of humic acid-biochar at a dose of 20 tons ha-1 increased soil pH, N-total, C-organic and mustard plant growth and yield. While the Urea fertilizer treatment at a dose of 200 kg ha-1 increased N-total, C-organic and mustard plant growth and yield. Meanwhile, there was an interaction between the combination of humic acid-biochar and urea fertilizer that significantly affected plant height.
