MODULE O SUPPLY
INTRODUCTION
The material in this Module will help trainees
obtain and correctly handle seed of appropriate
agroforestry tree species. Specifically, trainees
will learn how to identify good seed sources,
how to effectively store seed, how to test it for
viability and how to treat it before sowing to
increase chances for germination. Trainees will
also learn how to plan for seed collection as a
part of seasonal and annual activities.
CONTENTS
This Module contains the following lessons:
/ INTRODUCTION TO PROJECT SEED SUPPLY STRATEGY This lesson
provides an overview of your project’s seed supply strategy and what is required of field staff to
implement it
% e 6 4 w iji to o ls FOR IMPLEMENTING PROJECT SEED SUPPLY STRATEGY
This lesson consists of an extended series of exercises that provide trainees practical experience with
agroforestry tree seed.
Lesson 1 requires about an hour to conduct, plus preparation time. Lesson 2 takes four to five days
depending on the amount of time you spend identifying seed sources.

OBJECTIVE
Trainees will be able to describe their project’s strategy for obtaining appropriate agroforestry tree seed
and factors involved in effective seed procurement and handling. They will also be able to describe
Extension Staff roles in seed collection and handling.
METHOD
The lesson consists of a facilitated discussion. Use newsprint to record notes and discussion points.
EXAMPLE
Prepare
Review the LEARNING NOTES, Project Seed Supply Strategy. Adapt the notes according to plans for
your own project Prepare a presentation based on the NOTES.
Present the material using a question and answer approach. Encourage trainees to consider benefits of
local seed collection and factors affecting quality seed supply for the project
Summarize
Now that we know what is needed to ensure a good supply of quality tree seed for the project our
challenge is to learn to obtain and use tree seed effectively.

LEARNING NOTES Module 8
Lesson 1
PROJECT SEED SUPPLY STRATEGY
Our project strategy emphasizes the importance of seed collected locally. By locally, we mean within the
project area and nearby environments. This strategy has the following advantages:
QUALITY CONTROL
SECURITY OF SUPPLY
There is a better chance of having seed
available when seed is needed by the project
There is a better opportunity to obtain fresh
seed. This way we reduce chances that the
seed will lose its viability during its time in
storage.
This factor is particularly important for seed
which does not store well, such as Grevillea
robusta. Azadirachta indica. Gliricidia sepium
and many fruit trees, including citrus species.
It is important to know local sources of good
quality seed. Tree specimens that have
characteristics you want in your project trees
are the best to collect seed from. These
preferred seed-producing specimens are
called mother trees. Your project should identify
mother trees as regular sources of good quality
seed.
LOCAL ADAPTABILITY
There is a better chance that trees from local
seed will adapt better to environmental
conditions in your project area.
8-5
LESS EXPENSIVE
Generally, it is less expensive to obtain seed
locally than from outside sources.
LOCAL SELF-RELIANCE
Collection of seed locally promotes reliance on local resources. Farmers can make better use of locally
available seed. They will also learn ways to make sure that local seed produces the best possible results.
The biggest disadvantage of relying on local seed supply is that certain agroforestry species may not be
available. In addition, your project will need to plan carefully to ensure an adequate supply of local seed
to meet local demands. This may mean spending additional time building up knowledge about tree
species and seed availability in your project area.
Your project strategy for local seed supply should include the following:
Learn as much as possible about local tree species and the seeding time of each appropriate
species.
Learn about the location of good quality seed trees. Certain trees produce more regularly and
produce higher quality seed than others.
Organize and supervise seed collection activities on a timely basis.
Apply appropriate techniques for extracting, cleaning, drying, storing, viability testing and
pre-treatment of seed.
Ensure that seed distribution to local farmers in the project area is efficient Emphasize
distribution to farmers who are relatively close to the collection sites.
Record seed sources. Label seed packages or containers with the date of collection, the type of
seed collected and the source of the seed.
Assign someone on the project staff to be in charge of coordinating all seed supply operations.
