Report 24. Effects of seed treatment methods of germination of Simarouba glauca var. Latifolia Cronq.

Vaval, Fritz; Timyan, Joël (2019-09-03)

The seed of Simarouba glauca var. latifolia exhibits dormancy problems during storage and subsequent germination efforts. Five pre-germination treatments were selected to investigate methods to break post-harvest dormancy ...

Report 05. Microsymbiont colonization and seedling development as influenced by inoculation method : Rhizobium and Frankia

Reid, R. Kent (2019-09-03)

This investigation tested the various methods used in Haitian nurseries for inoculating tree seedlings with nitrogen-fixing organisms. Acacia, leucaena, and frene were inoculated with Rhizobium powder by oil-coat, water-coat, ...

Report 31. Development of stock quality criteria

Reid, R. Kent (2019-09-03)

This study examined survival and growth of seedlings of several species produced in standard and Deep 5 Rootrainers. The objectives were to test for differences between the two containers, and to determine the minimum size ...

Report 25. Time rate of discounting and decisions of Haitian tree planters

Street, Donald R. (2019-10-01)

During previous research on the economics of agroforestry in Haiti, it was noted that some farmers practicing agroforestry tended to hold onto trees for some years. They deferred harvesting them because some tree products, ...

Report 04. Seedling growth and development in different container types and potting mixes

Reid, R. Kent (2019-09-10)

This investigation tested the various containers and potting mixes used in the AOP. Effects were measured on nursery development of five non-nitrogen-fixing species (chene, kapab, cassia, neem, and ced). Four container ...

Report 09. Socio-cultural factors in Haitian agroforestry: research results from four regions

Starr, Paul D. (2019-09-03)

This report presents the results of research on socio-cultural aspects of agroforestry in the Des Forges, Bassin Bleu, Vialet and Maniche areas of Haiti. A total of 258 households were surveyed, 108 in Bassin Bleu and fifty ...

Report 23. A Geographic Information System (GIS) approach to locating potential planting sites for the Catalpa longisssima species (chene) in Haiti

Vaval, Fritz; Brown, Douglas C. (2019-09-03)

This paper reports the results of a preliminary study of the use of a Geographic Information System (GIS) approach to locating potentially superior sites for the cultivation of Catalpa Longissima species in Haiti. A total ...

Report 16. Soil profile description for selected sites in Haiti

Guthrie, Richard L.; Rousseau, Pierre M.; Hunter, Arthur Gene; Enilorac, Marie-Paule (2019-09-18)

Reliable recommendations for the development of agroforestry systems require accurate descriptions of the environment. Information on the properties of soils in selected sites is needed to expand agroforestry in regions ...

Report 27. A financial analysis of selected hedgerow operations in Haiti's Southern and Northwestern regions

Bellerive, Phillipe (2019-09-03)

The purpose of this study was to select, adapt and apply appropriate methods for a financial analysis of hedgerow and other agroforestry systems in Haiti, and to accomplish a study of some of the farms using such forms of ...

Report 21. Factors affecting seedling mortality in Haitian agroforestry

Elver, Harry (2019-09-18)

This study examined several factors influencing the mortality of samples of seedlings used in the Agroforestry II Project. Measurements were made of the rootball condition, leaf drop, plant turgor and internal box temperatures ...

Report 19. Biological, physiological and environmental factors affecting the health of trees important to Haiti

Runion, B. Brett; Kelley, Walter D. (2019-09-18)

This report contains an extensive, although not necessarily complete, listing of biological, physiological and environmental factors which can affect the health of trees in genera important to the people of Haiti. These ...
