EFEKTIVITAS PENERAPAN SONIC BLOOM DAN TANAMAN REFUGIA DALAM MENINGKATKAN PERTUMBUHAN DAN HASIL SAWI HIJAU (Brassica juncea L.)

The study was to examine the application of sonic bloom and refugia plants increase growth yield mustard greens (Brassica juncea L.). This used a Factorial Time Series Randomized Block Design (FTSRBD) with 3 replications. factor (R) are levels: R0 = control, R1 Ocimum basilicum, R2 Zinnia elegans different locations consisting (S0) no sound, (S1) heavy metal music frequency 21 -14000 Hz (S2) classical sound 21-13500 Hz. Data analysis continued according Duncan's Multiple Range Test (DMRT) at 5% confidence level. results showed that influenced plant through parameters height, number leaves, leaf area, chlorophyll stomata. Refugia type O. basilicum affect leaves parameter. rock affects pest attack intensity. interaction did not have significant effect on observed measured.
