  1. Farmers' Seed Systems Farmers continue to provide the large majority of seeds Some 80 to 90 % of the world's seed stocks are provided through an "informal" system, according to theInternational Center for Tropical Agriculture (CIAT). Such systems are locally organised and based on the ways...
  2. Abstract,Renewable Agriculture and Food Systems, 2005 Organic and low-input farmers often plant seed varieties that have been selected under conventional practices, traditionally including high inputs of artificial fertilizers, crop protection chemicals and/or water. In addition, these crops are...
  3. Abstract. HORTSCIENCE 2001 In order to avoid nematode damage to roots of Coffea arabica L. in Latin America, a common practice is interspecific grafting on C. canephora var. Robusta (Pierre) rootstocks. The performance of two C. arabica cultivars, ‘Caturra’ and ‘Catimor T5175’, was evaluated on...

TheProvision of Adequate Tree Seed Portfolio in Ethiopiaproject, led by World Agroforestry (ICRAF), has so far successfully established 14 breeding seed orchards in different parts of the country. The project is supported by the Norwegian International Climate and Forest Initiative represented by...
  5. 1969-01-19 In predominantly agricultural tropical countries the need to raise the production of good-quality foodstuffs and raw material is today greater than ever. The rise in production efficiency, so essential for our very existence, can be obtained only partly by improved cultural practices, increased...
  6. 2010-12-20 Evaluating the Underground Foundation Roots explore the soil for water and nutrients providing the foundation for growth and development. Understanding how root traits influence water and nutrient uptake can be important for crop varietal selection and improvement. Presenter :Katy Barlow,...
  7. Abstract, Experimental Agriculture, 1996 Farmer participatory approaches for the identification or breeding of improved crop cultivars can be usefully categorized into participatory varietal selection (PVS) and participatory plant breeding (PPB). Various PVS and PPB methods are reviewed. PVS is a...

  9. Participatory Plant Breeding (PPB) is a highly effective on-farm breeding method that involves a close collaboration between farmers and researchers. The approach provides farmers an opportunity to adapt crop varieties to their specific regions and organic farming practices. This toolkit includes...
  10. 2005-07-20 Over the years ECHO has been asked to give advice concerning whether or not to use hybrid seed. We carry very few hybrid varieties in our seed bank because we expect people who receive seed to multiply it locally. Now some new information about this old question, specifically about maize, has...
