Effect of plant growth regulators on growth, yield and quality characters of chilli (Capsicum annuum L.)

Abstract

The experiment to assess the effect of plant growth regulators on growth and yield parameters of chilli was conducted during the year 2020 at the farmer’s field, Venanallur, Ariyalur district. The experiment was laid out in randomized block design with seven treatments and three replications. Among all the treatments, the higher dose 60 ppm NAA resulted in increasing maximum plant height (67.82 cm), number of leaves (185.10), number of branches (25.42) and it also increased the, yield attributing characters such as fruit length (12.44 cm), fruit girth (1.15 cm), number of fruits per plant (140.77), number of seeds per plant (49.24), seed weight per fruits (0.81 g), chlorophyll content (2.56 mg/ 100g), capsicum content (0.18%), ascorbic acid content (121.54 mg/ 100g) and fruit yield per hectare (13.34 t) followed by 40 ppm NAA. There was an increase of 35 per cent in fruit yield with application of NAA 60 ppm respectively as compared to control. The minimum values of these characters were recorded under control.
