Section 3 • Living Soil, Integrated Soil Nutrient and Crop Managements
learning objectives
• To make participants aware of and understand how appropriate cultural management practices
in relation to growth stages of organically-grown root, tuber, and tuber vegetables can improve
productivity and profitability; and
• To learn innovative cultural management practices in relation to growth stages of organicallygrown
root, tuber, and tuber vegetables from other farmers.
materials
• Root and tuber vegetables organically-grown in learning and adjoining fields; and
• Office supplies (e.g., Manila papers, notebooks, ball pens, and marking pens).
methodology
• Field walks and brainstorming
steps
1. Divide participants in small groups and ask them to conduct field walks and observe different
stages of root and tuber vegetables organically-grown in learning and adjoining fields. Interview
other farmers, if necessary. List down all observations related to:
5 Kinds, varieties, or cultivars of root, bulb, and tuber vegetables planted;
5 Different growth stages of root, bulb, and tuber vegetables planted; and
5 Cultural management practices employed at different growth stages.
2. Go back to processing area; brainstorm in small groups and present output to the big group.
3. Conduct participatory discussion to allow sharing of experiences among participants and
facilitators. Motivate farmers to share their best cultural management practices employed
in relation to morphology and growth stages of different root, bulb, and tuber vegetables
organically-grown in their own farm, as follows:
5 Pre-planting operations (e.g., land and raised bed preparation, seed tuber selection and
dormancy breaking, vernalization, seedbed preparation and treatment, sowing, care
of seedling, roguing of diseased plants, cultural control of pests, furrowing and holing,
organic and microbial-based fertilizer application, pulling of seedlings, monitoring, etc.);
