Abstract

Seventy percent of Indonesia’s demand for soybeans is still imported, partly due to low crop productivity and decreased planting area. Sonic bloom, a technology that combines exposure of plants to sound waves of a certain frequency followed by application of liquid fertilizer through the leaves, is an alternative way to increase soybean productivity. This study aims to determine the growth response and N uptake efficiency of three soybean varieties on the use of sonic bloom technology. The research was a factorial experiment with a randomized block design (RBD). The first factor was the interval of using sonic bloom, I5: 5-day interval, I10: 10-day interval, and I15: once every 15 days. The second factor was soybean varieties, VA: Anjasmoro, VD: Dega-1, and VM: Mallika (black soybean). The data obtained were analyzed using Analysis of Variance with the F = 0.05 test followed by the 5% Honest Significant Difference (HSD) test. The results showed that different soybean varieties gave different growth responses to plant length, number of leaves and leaf area at sonic bloom intervals. The Dega-1 variety, which has thicker hairs (trichomes), requires more frequent application of fertilizer through the leaves using sonic bloom technology, namely once every 5 days. For the Anjasmoro variety, application of sonic bloom once every 10 days gave the best results, while for the black soybean variety Mallika the application of sonic bloom technology every 5, 10 or 15 days gave the same response. The highest N uptake efficiency was in the Dega-1 variety at intervals of using sonic bloom once every 5 days was 23.7%, while Anjasmoro and Mallika varieties had maximum N uptake of 23.7% and 21.8% at 10-day intervals.
