Abstract:
The objective of this study was to evaluate several commercially formulated biofertilizers in
reducing chemical fertilizers and pesticides to control of fruit rot and promote growth and yield
on chilli pepper. The experiment was carried out at the experimental field of Indonesian
Ornamental Crops Research Institute (IOCRI) located at 1100 masl from April to December of
2015. Eight formulated biofertilizers applied based on recommended instructions and
simultaneously compared with common farmer practices. The results showed that biofertilizers
gave varied effects on disease suppression, vegetative growths and reproductive characteristics.
Super Biost, Biotrico and Bio-Pf gave comparable affectivity with chemical pesticides employed
by common farmer in disease suppression. Bio-Pf induced better vegetative growth with wider
plant architecture In terms of reproductive characteristics, Bio-Pf, Bio-SRF and Biotrico and
Super Biost promoted competitive number of fruits and fruit weight per plant from common
farmer practice. Based on advantage analysis, the application of Bio-Pf and Biotrico had more
potential feasibilities than other biofertilizers. Both biofertiizers not only gave comparable fruit
rot suppression, growth and yield improvement, but reduced chemical fertilizers and pesticides
up to 50% employed by common farmer practices as well. |
