Long-term effects of soil conservation barriers on crop yield on a tropical steepland in Haiti 

Shannon, Dennis A.; Isaac, Lionel; Bernard, Carine R.; Wood, C. Wesley (2019-05-03)
In this research, we wanted to know how alley cropping between tree barriers compared to the more traditional conservation barriers used in Haiti in terms of long-term crop yields. Our hypothesis was that alley cropping ...

Promising tree species as hedgerows for alley cropping in different environments in Haiti 

Isaac, Lionel; Shannon, Dennis A.; Wood, C. Wesley; Bernard, Carine R. (2019-05-03)
Alley cropping is a system whereby annual crops are planted between rows of trees, which are pruned during the cropping season and the prunings applied as mulch or green manure. During periods where no crop is grown, the ...

Report 27. The effects of Leucaena hedgerow management on maize and hedgerow biomass yields over two years of cropping 

Isaac, Lionel; Shannon, Dennis A.; Brockman, Frank E.; Bernard, Carine R. (2019-09-05)
The objectives of the study were to identify optimum hedgerow management practices for alley cropping in order to optimize crop yield and hedgerow biomass production under lowland conditions in Haiti. The following ...

Report 29. Soil profile descriptions for agroforestry research sites in Haiti 

Guthrie, Richard L.; Isaac, Lionel; Alexis, Gerard; Bernard, Carine R.; Blemur, Marguerite (2019-09-05)
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 30. The effects of alley cropping and other soil conservation practices on maize (Zea mays) yields over two years of cropping 

Isaac, Lionel; Shannon, Dennis A.; Brockman, Frank E.; Bernard, Carine R. (2019-06-04)
The effects of different soil conservation practices on crop and hedgerow biomass yields were assessed under lowland conditions in Haiti over a period of two years. The trial was conducted at Pernier (1300 mm annual rainfall) ...
