Giving of Biochar and Biocompost to Growth, Results and N Uptake Soybean Plants (Glycyne Max (L) Merr.)

The use of biochar and biocompost can be one solution to the addition of organic matter in soybean cultivation. This study aims to obtain a good description of the role of biochar and biocompost on growth, yield, and N uptake. The results of the study show that: (1) Application of biochar in soybean plants affects plant height, number of vacuous pods, number of pods containing, weight 100 seeds, and N uptake compared with no biochar application. (2) Biocompost application has a significant effect on the height of soybean plants aged 2,3, 4 and 5 weeks after planting, dry weight, seed weight, number of vacuous pods and number of pods filled. (3) Biocompost with a liquid form dose of 2.5 grams/plant significantly affected the number of filled pods and the number of soybean pods. (4) Liquid biocompost dose of 5 grams/plant affects dry weight and plant height of 2 MST. While the 7.5 gram/plant liquid biocompost has an effect on the weight of soybean seed plants.
