One of the challenges facing projects that promote onfarmtree planting or forest plantations is how to provideseeds and seedlings at reasonable cost to planting sites.This can be overcome if planting is done on forest blocksites through the forestry department’s central nursery.Earlier attempts to promote community tree plantingbased on central nurseries operated by extension agentsor non-governmental organizations (NGOs) proved bothcostly and ineffective. To reduce costs, there are continuedefforts to decentralise seedling production anddistribution to community levels through groups or centralnurseries organized in schools, camps belonging tocommunity chiefs and privately managed nurseries.In the past, group nurseries often did not survive pastthe group formation or project support stage. Centralnurseries, also, were sometimes abandoned when fundingpriorities changed. Yet, there are success stories andmany farmers continue to be effectively reached throughsuch nurseries. Certain group nurseries, for instance,were left under the management of a single individualyet continue to supply seedlings to the community.Privately owned nurseries, in contrast, have been ableto survive for longer periods, albeit with little supportfrom developmental organizations. Depending on theoperating scenario, all three types (group, central andprivate) are feasible seedling supply alternatives and canevolve along with the awareness and tree planting cultureof the community.

Calliandra calothyrsus: nursery establishment and management
Calliandra calothyrsus is a small, leguminous tree with characteristic pink flowers. It grows in a wide range of climatic and soil conditions, from the sea level to the highlands, but it performs best in coffee zones. Acidic soils, waterlogging and frost affect its growth negatively. Calliandra grows relatively fast and its economic benefits can be realized in the first year after planting. The tree can produce fodder continuously for more than 10 years. It can be grown in various sites on the farm since it does not compete much with crops growing adjacent to it, as long as it is properly managed to reduce the shading effect.
Agroforestry seed technology and nursery management: a training manual
The succes of agroforestry as a land-use management system depends, among other things, on quality planting materials for optimum production. Recent developments in technology present various alternatives to producing such planting materials. Of these, the combination of biotechnology with indigenous or traditional propagation techniques have gained wide aceptance and, through practice, have proven essential in seed technology, and nursery establishement and management.
Agroforestry tree seed production: production guidelines for seed orchards
Community-based forestry and agroforestry programs around the world reforest denuded lands, protect valuable watersheds and produce indispensable tree products for soil improvement and fodder. These programs begin planting operations with a commodity of small size but great importance-seed! Adequate supplies of high quality seed are necessary to grow high quality seedlings. Unfortunately, shortages of seeds are common and limit the success of many community-based tree planting programs. Any discussion about tree seed production must consider the saying “garbage in garbage out”. If you plant junk seeds you will inevitably harvest junk trees.
Germplasm supply, propagation and nursery management of miombo fruit trees
In this chapter, we review the state of knowledge about germplasm delivery and the propagation and nursery management of miombo fruit trees in Africa. The chapter will be limited to examples relevant to small-farm agroforestry systems in southern Africa as opposed to highly intensive monocultural orchard production systems. We discuss the factors involved in determining the most appropriate methods of propagation for particular species, and the associated constraints and limitations in scaling up the domestication of indigenous fruit trees in southern Africa
