Abstract:

Soybean is the one of agricultural commodities that was very needed in Indonesia, neither as a human food, animal feed nor a basic material of industry. In the development of soybean plants, there were some issues that related to the agro-ecosystem during the planting and it must be overcome, the one of them was the problem of the weeds management that have not optimum yet. The purpose of this research is to examined the effectiveness of a combination of some organic mulchs towarded the weeds suppressing ability on the growth and yield of soybean. In this experiment, it was conducted the effectiveness of acasia organic mulch to suppress the growth of weeds, and also the testing of community coefficient, vegetation analysis (initial SDR value, middle and final), the weeds heavy with broad and narrow leaf types, and kinds of other teki-tekian. Plant’s growth (height, dry weight of shoots and roots). The yield components (amount of pods, amount of meaty pods, weight of 100 seeds and the yield of soybean). The experiment was conducted in a Group Randomized Plan. From the results of this study, found that the Acacia mulch is the organic mulch that effective to suppress the growth of weeds, especially in doses of 20 tons per-ha-1 of mulch Acacia.
