The effectiveness of liquid biofertilizer from waste bioconversion using black soldier fly larvae on the growth of arabica coffee seedlings

The organic waste treatment process using Black Soldier Larvae ( BSF ) produces liquid biofertilizer LB that contains functional microbes and macro micronutrients potentially can stimulate plant growth. study aimed to determine the effectiveness of from bioconversion by on growth arabica coffee seedlings. experiment used a randomized block design with 7 treatments, which consisted of: no (control), 1.5% spraying, 3% 6% watering, 12% 4 replications each replication containing 10 plants. All treatments were given once month, 1-month-old test results showed application significantly increased stem diameter number leaves Arabica seedlings months after (MAA). In aged MAA, spraying resulted in highest increase diameter, while was obtained watering . Additionally, 12 old seedlings, coffee's fresh shoot weight compared other treatments.
