Effect of Plant Growth Regulators on Growth and Yield of Sweet Pepper

Abstract

A field experiment was carried out to study the effect of plant growth regulators on growth and yield of sweet pepper (cv Indra) in Rayagada district of Southern Odisha during September-January of 2019-20 and 2020-21. The experiment was laid out in Randomized Block Design with three replications and seven treatments. From the present study it was revealed that the maximum plant height (43.3 cm) was obtained with IAA (100 ppm) whereas maximum fruiting branches (8.20), maximum fruit weight (106.80 g) was obtained with 2,4-D (10 ppm). Maximum polar diameter (6.6 cm), shoulder diameter (5.2 cm) and single fruit weight (82.3 g) was obtained with BA (5 ppm). Maximum fruit yield (13.8 t/ha) was recorded with BA (5 ppm). Early fruit fetches higher market price than late harvested fruit and gives higher return to farmer which was obtained by application of BA (5 ppm) i.e., 28.1 days for first flowering and 60.2 days for first harvesting.
