Regosol is soil that has a low level of soil fertility and water availability. According to internet of tings information system used to monitor soil moisture, water use will be more efficient. This study aims to apply the Internet of Things information system to monitor soil moisture in capillary irrigation and liquid organic fertilizer, study the capillary irrigation system and liquid organic fertilizer on the growth of mustard greens (Brassica rapa. L) and soil characteristics. The method used in this study was a completely randomized design (CRD) with two factors. namely Type of fertilizer, consisting of 4 levels, P0: No liquid organic fertilizer, P1: 5 liters/ha Household waste liquid organic fertilizer, P2: 5 liters/ha Biduri leaf liquid organic fertilizer, P3: 300 kg/ha NPK fertilizer. The second factor is the number of wick of capillary irrigation, consisting of 3 levels: I0: No capillary irrigation, I1: 1 wick capillary irrigation, I2: 2 wicks capillary irrigation. The results showed that the soil moisture during the growth of mustard greens was 16.59 to 23.48 %, the more capillary wicks, the higher the soil moisture. The average water requirement for mustard plant growth is 3.16 liters. Mustard plants begin to wither and lack water at 6.47 % soil moisture. Liquid organic fertilizer and capillary irrigation had a significant effect on leaf width, but had no significant effect on plant height, plant wet weight, plant dry weight, soil moisture, soil pH. Liquid organic fertilizer has a significant effect on soil C-organic and soil NPK levels, while capillary irrigation has a significant effect on water volume.
