The aim of this reasearch is to determine difussion coefficient of nutrient solution through rice husk charcoal mortar walls. This research used completely randomized design (CR) with factorial arrngement which consisted of factors. The first factor, the material composition ratios of mortars (cement : sand : rice husk charcoal), consisted of two levels: P 1 (1:3:3) and P 2 (1:3:4). The second factor, the concentration of nutrient consisted of ree levels, namely K 1 (3 mS/cm), K 2 (6 mS/cm), and K 3 (9 mS/cm). Data set was analyzed by using ANOVA,then followed by using LSD at 5% significant level. Anova showed that there was interaction between mortar material composition and nutrient concentration. The best diffusion coefficient was found in the treatment P 2 K 1 and P 2 K 2 (1:3:4 and the nutrient concentrations 3 mS/cm, 6 mS/cm). Nutrient solution in the treatments could pass through the walls of mortar very well, so that it could be used as a means of fertigation.
