ABSTRACT

The investigation on effect of growth regulators on yield and quality of paprika cv. KtPI-19
revealed that the growth regulator spray had significant influence on yield and quality. Spraying
of NAA 25 ppm significantly increased the number of flowers / plant, Number of fruits per plant
and fruit set percentage in winter season, whereas spraying of NAA @ 50 ppm showed increased
in fruit weight, fresh fruit yield / plant, fresh yield / plot and dry yield / plant in winter season and
all the above parameters in summer season. In case of quality parameters 2, 4, D @10 ppm shows
increased ascorbic acid and TSS content in paprika cv. KtPI-19 in both winter and summer season.
Oleoresin, capasaicin and capsanthin content were highest in the plants sprayed with NAA @ 50
ppm in both winter and summer season. From this investigation, it is concluded that NAA @ 50
ppm spray was beneficial in paprika cv. KtPI-90 for increased yield and quality
