Utilization of Sonic Bloom Technology Combination of Compost Tea and Surfactants to Increase Soybean Productivity (Glycine max (L.) Merrill)

Abstract

Purpose: The study aimed to determine the effects of organic compost tea liquid fertilizer, inorganic fertilizer, and surfactant application on soybean growth and the yield of sonic bloom technology.   Method: The study was conducted in a greenhouse scheming factorial experiment with randomized block design (RBD).   Findings and Conclusion: Likewise, the results indicated that the use of organic compost tea liquid fertilizer with a concentration of 15% enhanced the plant length, the number of leaves, and the leaf area, which were insignificantly different from the inorganic fertilizer growmore combined with surfactants. The yields of productive branches of 100 seeds weight, fresh weight, dry weight, and Harvest Index showed that 15% compost tea with surfactant gave identical decent results to growmore fertilizers with surfactants. Moreover, there was an increase in soybean productivity by 216% in scheming 15% compost tea combined with surfactants.   Research implications: However, the result did not distinguish significantly from the use of liquid inorganic fertilizer grow more with recommended dose + surfactant increased by 219% from the potential production of soybean variety with Dega-1, which was 3.82 t/ha.
