Performances of Coleus tuberosus grown on an acid mineral soil in lowland area in Bengkulu revealed vigorous forms. This grown performances based on the research conducted in the Research Station of Agriculture Faculty, University of Bengkulu lies on 6 m above sea level. Agro-climatology condition around this center has rainfall of 265 mm month-1, daily temperature of 26.5 0C average with maximum temperature of 32.9 0C, and of 22.2 0C minimum temperature, and relative humidity of 84%. The research station was covered by Ultisol, acid mineral soil with chemical characteristics of marginal soil pH 4.80, C-organic content in medium level of 2.15%, N-total 0.14%, P-available 9.20 ppm, Exchangeable-K, -Ca, -Mg, and –Na were 6.18; 2.64; 0.42; and 0.56 me 100g-1, and exchangeable-Al, 1.36 me 100g-1, respectively. Soil texture was composed of sand 21.60%, silt 47.75%, clay 30.65% with texture class of clay loam. The performances of the growth crop of Coleus tuberosus showed length of plant when harvested of 3 month after planted was 110 cm average in which the higher was about 179 cm. Average of branch was of 26, and the highest branch was 44. A plot area of 3 m2 yielded about 3.2 – 7.8 kg tubers in which the biggest tuber was 7.0 cm length and diameter of 5.0 cm with weight of 50 g.
