Effect of different concentration of plant growth regulators on growth and quality of green chilli

Abstract

A field experiment entitled “Effect of different concentration of plant growth regulators on growth and quality of green chilli” was conducted at Chilli and Vegetable Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif season of 2016-2017. The experiment consists of ten treatment comprising plant growth regulators and their mode of application and was laid out in randomized block design having three replications. There were three plant growth regulators were use with different combinations and were applied by foliar application at 30 DAT, 60 DAT, 90 DAT to assess the effect on growth and quality of green chilli. The investigation revealed that, the vegetative growth observations in terms of plant height of plant was produced in the treated with NAA at 50 ppm and number of branches per plant were produced significantly the maximum due to application of CCC at 500 ppm. The plant spread was found significantly the maximum when the treated with an NAA at 50 ppm. As regards to the yield parameters which were recorded viz. fruits per plant of green chilli were produced significantly the maximum due to an application of NAA at 50 ppm concentration. As far as the fruit quality concern in terms of fruit length was observed significantly the maximum obtained an application of GA3 at 50 ppm, significantly the maximum fruit breadth was obtained with an application of CCC at 500 ppm concentration and the other quality parameter like in respect to the chlorophyll content i.e. chlorophyll A, chlorophyll B and total chlorophyll were observed maximum when the treated with CCC at 500 ppm concentration.
