Berry Drop Management in Black Pepper through On Farm Testing in Uttara Kannada

On farm testing was conducted at farmer field to study the effect of different technology options like Di-Ammonium Phosphate and Naphthalene Acetic Acid spray at berry set and fruit development stage, respectively and Naphthalene Acetic Acid at berry set and fruit development stage to prevent berry drop in black pepper. The results indicated that spraying of Di-Ammonium Phosphate 1.5 per cent and 25 ppm Naphthalene Acetic Acid at berry set and fruit development stage has improved many commercially desirable parameters like number of berries per spike, higher per cent reduction in berry drop and yield in black pepper (Piper nigrum L.). Benefit cost ratio, however, was also highest in the treatment compromising Di-Ammonium Phosphate and Naphthalene Acetic Acid.
