Research Project: Carrot and Onion Seed Production and Related Postharvest Innovations to Provide Well-Adapted and Nutritious Vegetables for Bangladesh

Location: Vegetable Crops Research Unit

2013 Annual Report


1a.Objectives (from AD-416):
1. Identify high-yielding, nutritious onion and carrot cultivars adapted to a major South Asian production area. 2. Establish Bangladesh oriented crop production and postharvest storage guidelines and manuals, programs and cell phone based information to integrate water, nutrient and pest management practices that optimize inputs, minimize off target impacts, and provide sound postharvest storage practices for seed production. 3. Establish onion and carrot seed production systems to better fulfill local demands with a goal to decrease expensive seed imports, increase crop yield and improve human nutrition. 4. Establish collaboration with AVRDC/WVC on large-scale carrot and onion seed production (large-scale seed production not currently part of their onion effort).


1b.Approach (from AD-416):
1. Germplasm Collections and Field Trials. Collect and evaluate local and regional onion and carrot seed in Bangladesh. Evaluate carrot carotenoids and onion thiosulfinates in diverse germplasm to estimate nutritional value and develop molecular marker fingerprints. 2. Seed production. Evaluate factors that influence onion and carrot seed production including nutrient, water, and pest management. Develop recommendations based upon on-farm research results. 3. Postharvest storage. Develop post-harvest storage systems for carrot root and onion bulb preservation to induce flowering for seed production. Develop recommendations necessary for farmers to successfully store roots and bulbs for seed production. 4. Initiate deployment of technologies: Determine opportunities to incorporate carrot and onion storage into existing cold storage facilities to move research and technologies developed to large-scale. 5. Train farmers, homestead owners, rural youth and women on seed production methodologies. Training of trainers (TOT) to further extend information on information and technologies developed to local trainers. Train research supervisors of GO, such as BARI, and NGO personnel, providing pertinent information to the user community. Participation of rural women and unemployed rural youth in this system will be a focus.


3.Progress Report:

This project was renumbered from 3655-21000-048-49A to 3655-21000-062-23A. Diverse carrot and onion seed sources being grown in Bangladesh were collected, field tested, and data gathered in Bangladesh. Carrot roots from field trials were stored and seed productivity was evaluated in Bangladesh. An initial gathering of on-farm vegetable seed production information was initiated in Bangladesh. Information for training of trainers was prepared and some farmer’s training is being scheduled at the village level for farmers in the onion seed growing areas, with gender equity as an integral component to providing this training. On-farm vegetable seed production information was gathered to be shared and jointly expanded based upon the collective experience of the Bangladesh-U.S. team.
