materials
• Organic vegetable fields planted to vernalized and non-vernalized radish seeds;
• Field supplies (e.g., radish seeds, filter papers, and plastic boxes);
• Refrigerator (e.g., temperature of 5 °C can be maintained regularly); and
• Office supplies (e.g., Manila papers or blackboard and chalks, notebooks, staplers, crayons, ball
pens, and marking pens).
methodology
• Field walks, hands-on, and brainstorming
steps
1. Divide participants in small groups and ask them to conduct field walks, interview farmers, and
observe organic vegetable fields planted to either vernalized or non-vernalized radish seeds.
List down all observations and experiences shared by farmers interviewed.
2. Go back to processing area. Brainstorm in small groups on how to improve standard procedure
provided below:
5 Line bottom of plastic boxes with filter papers;
5 Broadcast thinly radish seeds on filter papers;
5 Moisten filter papers and seeds;
5 Keep seeds in boxes at room temperature until radicles break off seed coat;
5 Place pre-germinated seeds in a refrigerator section where temperature can be maintained
at 5 °C for 14 days; and
5 Sow vernalized seeds in seedbeds prepared with 30 x 30 cm spacing.
3. Present output of small groups to big group. Conduct participatory discussion and sharing of
experiences among participants and facilitators.
4. Synthesize and summarize output of small groups into one big group output. Draw up
conclusions and recommendations from this exercise.
