Abstract/ Executive Summary:

Leafy vegetables in Chapai Nawabganj district of Bangladesh was studied from January to December 2019. A total of 111 species belonging to 59 genera under 30 families were recorded, out of which, 52.25% species were wild and 46.84% species were cultivated in this study. Status of occurrence has been recorded for proper conservation management and sustainable utilization of the taxa resulting in 81.98% to be common, 17.11% as rare and 0.90% are found as vulnerable in the study area. A total of 93 medicinal plants have been documented with their uses for the cure of more than 53 diseases. The study showed that the people of Chapai Nawabganj district use leafy vegetables to treat their diseases. Therefore, the documented leafy vegetables should be further investigated for their efficacy and safety to be integrated into conventional medicine. Further more these leafy vegetables need to be conserved for their sustainable utilization.

Keywords: Assessment; Leafy vegetable taxa; Indigenous uses; Ethnobotany, Taxonomy

Location: Chapai Nawabganj is located on the north-western part of Bangladesh.

Start Date: 00-01-2019

End Date: 00-12-2019

Program Area: Postharvest and Agro-processing

Commodity: Medicinal Plants

Objectives:

To identify and document the plant species. In view of potential beneficial attributes of leafy vegetables, there is a need to explore, identify and document the leafy vegetables of Chapai Nawabganj district, Bangladesh.

Methodology:

Study area- Chapai Nawabganj is located on the north-western part of Bangladesh. It is a part of the Rajshahi Division and known for its special tone of local dialect. The north and west part of Chapai Nawabganj is bounded by Malda and Murshidabad district of India, east is by Naogaon District, and south-east is by Rajshahi District (BPC, 2001). Data collection- The work is based on fresh materials collected during twenty three visits to Chapai Nawabganj distict, Bangladesh from January to December 2019 to cover the seasonal variations as well. The visits covered all types of habitats, particular river bank, slope, village grove, fruit gardens and roadsides of the study area. Medicinal information was obtained through semi- structured interviews with knowledgeable people such as local ‘Kabiraj’(local herbal doctor) and elderly people. A total of 161 informants having an age rang from 21 to 69 years were interviewed using semi-structured interviewed method (Alexiades, 1996). Plant parts with either flower of fruits collected using traditional herbarium techniques to make voucher specimens for documentation. Plant identification- Collected specimens have been critically examined, studied and identified. Identifications have been confirmed by consulting standard literatures (Hooker, 1877; Prain, 1903) and Herbarium of Rajshahi University (HRU). Nomenclature has been updated following recent literature (Ahmed et al., 2008-2009; Huq, 1986, and Pasha and Uddin, 2013).

Achievement/Findings:

This finding suggests that the leafy vegetables may possibly contain other phytochemical constituents which need to be investigated in future studies. The present study revealed that medicinal plants still play an important in the primary health care of the rural communities. The information gathered from the local traditional healers are useful for further researchers in the field of ethnobotany, taxonomy and development of new drug from natural resources.
