Pertumbuhan Talas Beneng (Xanthosoma undipes K. Kock) Pada Tanah Dystrudepts Yang Diaplikasi Kompos Solid Pada Berbagai Naungan

---

SUMMARY
The strategy for developing beneng taro (Xanthosoma undipes K. Kock) can be carried out by using it as an intercrop in oil palm plantations that utilize Dystrudepts soil. The obstacles faced are that the optimal level of shade for the growth of beneng taro is not yet known, as well as the high level of soil acidity and low nutrient content. One effort to overcome this problem can be done by providing compost. This research aims to determine the effect of shade on the microclimate as well as the effect of compost dosage on soil physical properties, soil chemical properties, plant growth, plant production at different levels of shade and to determine the percentage reduction in fresh weight of beneng taro tubers at different levels of shade.
The research location is located in the experimental garden of the Faculty of Agriculture, Riau University, Binawidya Campus Km. 12.5 Simpang Baru Village, Tampan District, Pekanbaru. This research is a 4x4 factorial experiment using a Split Plot Design with a basic design, namely a Completely Randomized Design (RAL). The main plot is the shade level and the subplot is the compost dose. Each treatment was repeated 3 times to obtain 48 experimental units. The shade treatment is the main plot with 4 levels, namely N0 = 0% shade, N1 = 25% shade, N2 = 50% shade and N3 = 75% shade, while the solid compost treatment is the subplot with 4 levels doses, namely K0 = 0 tons ha-1, K1 = 6 tons ha-1, K2 = 12 tons ha-1 and K3 = 18 tons ha-1. The variables observed in this research include 4 groups, namely microclimate, soil physical properties, soil chemical properties, plant growth and plant production. The data obtained was analyzed statistically using analysis of variance. If the variance results are real, then the Honestly Significant Difference (BNJ) test is continued at the 5% level.
The results of the research show that providing increasing levels of shade results in decreasing light intensity and air temperature, but results in increasing air humidity. Providing increasing doses of compost resulted in water content at a depth of 0-10 cm and cation exchange capacity increasing at different levels of shade. Providing increasing doses of compost resulted in increased bulb circumference, leaf length and leaf width at different levels of shade. Providing increasing doses of compost resulted in increasing plant fresh weight and plant dry weight at different levels of shade. A shade level of 0% produces the highest fresh weight of tubers. A shade level of 25% resulted in a reduction in tuber fresh weight of 6,9%. A shade level of 50% resulted in a reduction in tuber fresh weight of 18,6%. A shade level of 75% resulted in a reduction in tuber fresh weight of 23,2%.
