<![CDATA[This research purposed to know the effect of biofertilizers, the effect of soil type, and the effect of interaction between biofertilizers and soil type on growth and yield arrowroot. This study uses a randomized block design with 2 factors, namely biofertilizers of biota max consisting of 2 levels and types of land consisting of 2 levels. Analysis of the data using Analysis of Variance and continued with Test of Least Significant Difference at the level 5%. The results of this study indicate that: 1) application of biofertilizer is effect significantly against increased in the number of leaves, number of tillers total, relative growth rate and net assimilation rate, the number of tubers per hill, tuber diameter, tuber length and weight of tuber per hill than without the application of biofertilizers, 2) arrowroot planting in soil grumosol significant effect against increased crop height, number of tillers total, relative growth rate, leaf area index, and the number of tuber per hill than arrowroot planting in rendzina soil.]]>
