Seasonal variation in morphological characteristics of Brahmi (Bacopa monnieri) germplasm accessions in coastal regions of Andhra Pradesh

Abstract

A field experiment was carried out during 2023-24 at Horticultural Research Station, Dr. YSR Horticultural University, Venkataramannagudem, West Godavari District, Andhra Pradesh to study the impact of different season on the morphological traits of Brahmi (Bacopa monnieri) germplasm accessions. The study employed a randomized block design with two replications evaluating morphological traits such as plant height, number of leaves, number of nodes, stem length, number of stolons and number of branches. Results revealed that kharif season consistently outperformed both Rabi and summer seasons, exhibiting significantly superior morphological characteristics across the evaluated variables. Maximum plant height obtained in APBm-10, APBm-1 and APBm-16 during kharif, Rabi and summer respectively. APBm-14 showed maximum number of leaves, stem length and number of branches during kharif and Rabi season. APBm-5 showed maximum number of leaves, branches and stem length in summer. APBm-10 recorded maximum for number of nodes during all seasons. For number of stolons APBm-1, APBm-21 and APBm-3 and APBm-4 showed maximum values in kharif, Rabi and summer respectively.
