The effects of BIOGREEN bioorganic fertilizer on the test crops (tomato, pepper, and bitter gourd) were evaluated in comparison with commercially available chemical fertilizers following efficacy test protocol guidelines by the FPA [Fertilizer and Pesticide Authority, Philippines] and Farmer's Practice. BIOGREEN bioorganic fertilizer at 20-50 kg bags/ha, generated increased yields in tomato by 10.2 percent (or 0.63 t/ha) over the control. Also BIOGREEN bioorganic fertilizer gave a yield of 6.78 t/ha and matched the yield of the full (120-120-120) and half-recommended rate of chemical fertilizer at 60-60-60 (7.8 t/ha and 6.32 t/ha, respectively). Results showed that the use BIOGREEN bioorganic fertilizer alone on bell pepper had an increased yield of 41% or equivalent to 2.0 t/ha over the control. BIOGREEN bioorganic fertilizer also exhibited a higher yield (6.88 t/ha) than half RRC (6.69 t/ha). Moreover, observations showed that the use of BIOGREEN bioorganic fertilizer was also suitable in hot pepper. In bitter gourd efficacy trial, BIOGREEN bioorganic fertilizer exhibited the highest yield among treatments. A marked difference of 7.8 t/ha was observed against RRC and about 186% yield increase (13.46 t/ha) over the control.
