materials
• Organic vegetable fields planted to hydroized and non-hydroized tomato or carrot seeds;
• Office supplies (e.g., Manila papers, notebooks, ball pens and marking pens); and
• Field supplies (e.g., tomato or carrot seeds, clean water, plastic boxes and plates).
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 hydroized and non-hydroized tomato or carrot 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 Weigh seeds and add water equivalent to 75 % of seed weight;
5 Stir properly until all seeds are wet;
5 Keep wet seeds at room temperature for 24 hours;
5 Dry wet seeds under diffuse light for three days or until they return to their original
moisture content; and
5 Repeat procedure once or twice before sowing seeds.
3. Present output of small groups to the big group. Conduct participatory discussion to allow
sharing of experiences among participants and facilitators.
4. Synthesize and summarize output of small groups into one big group output. Draw up
conclusions and recommendation from this exercise.
some suggested question for processing discussion
❏ What do we mean by pre-sowing hardening or hydroization?
❏ Did you observe tomato and carrot planted in farmers’ field whose seeds were hydroized? How
were they compared with tomato or carrot whose seeds were not hydroized?
❏ Why do we need to harden tomato or carrot seeds by hydroization?
