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.
