Abstract


Dry land based on agroforestry has the potential to be utilized, but there are limiting factors such as low soil fertility. The use of organic fertilizers and biochar can increase soil fertility. The purpose of this study was to examine the response of soybean growth to the application of types of organic fertilizers and types of biochar. The study was conducted in March-June 2022 at RPH Gunung Kidul, Yogyakarta and was designed with factorial RAKL. The first factor: the type of biochar consists of control, rice husks, and coconut shells. The second factor: the type of organic fertilizer consisting of control, organic chicken, organic cow, organic goat. Experiment was repeated 3 times. The data will be analyzed using ANOVA, if it has a significant effect then the DMRT test is continued at the 5% level. The results showed that rice husk biochar gave the highest plant height, number of leaves, number of branches, leaf area and dry weight of stover on soybeans. Chicken organic fertilizer gives the highest yield on plant height. Goat organic fertilizer gave the highest yield on the number of branches and number of leaves. Cow organic fertilizer gave the best yield of leaf area and dry weight.
