The ecological fabric that has nurtured the soil and supported life for millennia gradually has been unraveled by human activities. Tree species cultivated here must supply valuable products and services and require low establishment costs. There is a collection of native and exotic species that plays an essential role in the agricultural landscape. Several of the more important ones are included in Part I. Part II compiles useful information of a more technical nature and covers a wider range of species. A reference section has been included for those interested in studying these tree species in greater depth. The Haiti Agroforestry Research Project was a program to encourage Haitian farmers to plant fast growing trees as a cash crop. This project was part of an overall plan by USAID to curb the devastating erosion which was washing the top soil into the sea. https://aurora.auburn.edu/handle/11200/49750 https://aurora.auburn.edu/handle/11200/49617 Report 20. Storage conditions and pre-germination methods for seed of selected tropical tree species This document summarizes tree seed storage conditions and pre-germination methods of major species utilized in Agroforestry II, a USAID funded agroforestry project in Haiti. The study is not meant to be an exhaustive review of the subject, and is designed to provide the practitioner with the necessary information to store and germinate tree seed optimally. It is likely that the species list be expanded in the future. However, the information contained in this document is generally appropriate for most species, and serves as a base for experimentation of other tropical and sub-tropical species. The data is summarized from responses to a request for information from 10 institutions and 9 countries. Many of the experts from these institutions have extensive experience and research in the area of seed technology that is contained in this document. Literature references are provided to guide the reader to more detailed and comprehensive coverage of the tropics.; Rapó sa bay kondisyon sa yo ki ta pemet nou estoke semans pye bwa yo pi byen. Infomasyon ki bay nan rapó sa-a dwe ogmante sa nou jwenn nan Gid Pepinyeris, chapit 3 ki ekri pa PADF. Gen twa kondisyon nou kapab kontwole pi fasil. Se 1) kalite sache kap estoke semans la; 2) nivo tanperati nan kote nou estoke semans la; 3) kantite dlow nou kite nan semans-lan pandan yo estoke pou plizye mwa. Nou bay infomasyon pou tanperati estoakj ak imidite semans pou chak kalite bwa nou etidye nan Table I. Ankó, semans ki soti nan kek kalite bwa mande yon tretman avan nou seme yo nan pepinye. Pou chak kalite bwa, nou bay infomasyon sa-a nan Table II. KONSEY 1. PADF e CARE dwe kontwole mwa kapab konseve semans chak kalite bwa nan kondisyon yo gen kounye-a. Sa ki pi enpotan se tanperati e kantite dlo ki nan semans kap estoke. SECID dwe kompare kondisyon ke lot peyi ap rekomande ak sa PADF ou CARE ap fe. Eske diferan kondisyon pou chak kalite bwa impotan pou nou konseve semans yo? 2. Nou dwe mete plis impotans nan rechech pou kalite bwa yo ki bay semans yon sel fwa pa ane, oubyen ki konn bay move rekolt semans tanzantan. Sa dwe fet paske nap oblije estoke semans pou le pepinye bezwen semans la, pa selman tel kalite bwa ap bay yon bon rekolt. Kalite bwa ki bay grenn nimpot le, ou bay anpil grenn ki pa pouri fasil, pa mande nou fe anpil rechech. 3. Kalite bwa ki bay semans ki frajil ou ki pap viv lontan mande nou fe rechech nan lot jan pou leve bwa yo. Tout kalite bwa pa mande nou konseve yo kom semans. Si gen pwoblem estokaj, nou dwe we ki jan nou ka motive moun yo pou yo ta pran ti pye bwa ki leve anba maman bwa yo oubyen seme semans yo direkteman nan platban bo lakou pou yo ka plante nan bon sezon lapli. Nou ka fe sa pou nim, frenn, mango, kajou, zoranj, sitron, chadek, eplizie lot kalite ki bay pwoblem stokaj. 4. Tretman semans ki fet avan yo seme nan pepinye dwe fe tout semans leve mem le e anko, li fe yo leve pli vit. Li bon paske sa fe tout plantil yo rive menm wote ansam. Si gen plizye tretman pou yon kalite semans, nou dwe chwazi sa ki pli fasil e ki bay nou bon rezilta. 5. Kote PADF e CARE ap estoke semans an gran kantite, nou oblije instale yon delko ki mache tout tan lé EDH pa bay kouran. Delko sa-a dwe komanse e rete otomatik, pou moun pa bezwen okipe li tout tan. Konsa, tout ekipman ki anplas pou estoke semans yo nan bon kondisyon pap rete mache. 6. Tout rechech laboratwa oblije swiv reg yo ki ekri nan ISTA (1985). Nou dwe swiv dokiman sa jiska li pa bon anko, oubyen gen lot pi bon konsey sou teknik pou egzamine semans yo.

Impact des haies vives sur la production agricole Declining yields and land degradation are becoming more dramatic every year in spite of increasing foreign aid. Population growth far exceeds food production capacities. However, the effects of all agricultural development programs of any importance at the regional level are only felt on a medium or long term basis. Agricultural development is a multidisciplinary effort involving research and extension services. Agricultural development needs to take into consideration the economic factors necessary to insure not only the national goals, but also the goals of the individual, be he a producer or a consumer. The reduction of the fallow duration together with the loss of nutrients due to the removal or destruction of crop residues and erosion of fine soil particles (clay), induces the decline in soil fertility and land degradation. This kind of "mining" agriculture that prevail in Haiti is the basis for over exploitation of the land. Hillside farming in Haiti is practiced primarily by small farmers, and measures must be taken to help them maintain or improve their production capacity. The introduction of techniques, measured, also have a medium and long term impact on soil conservation as well as soil fertility. In selected sites, hedgerows have been evaluated in terms of their efficiency in conserving soil and maintain soil fertility as well as their effect on crops. This study has shown that in the mixed cropping farming practices currently prevalent in Haiti, and within an experimental context, crop yield are not affected by the hedgerows or their associated crops. Experimental results show that hedgerows are a source of impressive soil savings, on the order of 70 tons per ha per year which on one hectare of land represents 7 mm.; Chak ané Hayiti ap pedi tè li è tè-a ap vin pi meg malgré gwo peyi yo ap bay plis aid.

Time rate of discounting and decisions of Haitian tree planters 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, such as planks, increase in value as the trees mature. This study examines the decisions made by rural Haitian tree planters and by urbanites with regard to the amount of time each would defer a benefit that would later have greater value. It examines the time rate of discount, planter planning horizons, and alternative use plans. Data on the time rate of discount for groups of tree planters and urban service workers are reported. A regression analysis examines the influence of age of farmer and age of tree on such decisions. Respondents expressed very high time rates of discount of future returns. A negative relationship of the discount rate and age of oldest trees was observed, while a positive relationship of the discount rate and the age of the cooperating planters was shown. Political instability influenced farmers' decisions. Greater stability would encourage investment at lower rates of interest because of lower risks of losses. In addition to the use of wood products in building construction and as fuel, potentially profitable opportunities in the Haitian economic for additional uses of wood products are described, including the wood carving industry.; Nan reshesh ekonomik ki te fet nan zafè plante pyebwa an Ayiti yo te obsevé ke gen kek kiltivatè ki plante pyebwa e ki te kité yo pandan plizye zane. Yo pat koupé pyebwa yo paské yo te rekonet plis pyebwa yo gwo plis yo bay ranman, espesyalman nan zafè fey plansh. Etid sila ap ekzaminé konbyen tan kiltivatè pyebwa epi tou, kek moun nan la vil-la, te dako gadé yon bagay ki te kapab rapoté yo pi plis demen. Nan etid sila, yon rapo te bay sou valè tan group plantè yo epi tou, moun kap travay en deyo yo te dako kembe yon bagay ki te kapab rapoté yo pi plis demen. Yon analiz (regression) te montré koman laj kiltivatè yo e laj pyebwa yo kap jwe yon grann en potans nan zafe sila. Resilta-yo montré ki pousantaj tan ke moun yo te vle gadé yon bagay ki kapab bay yo yon pi gwo benefis pi devan ki te byen gran. Li te montré tou, plis pyebwa yo te ajé, mwens abitan-an te genyen interè pou li pat koupé yo, epi tou, moun yo ki te gwoupé an cooperativ te genyen plis tandans pou ko kite pyebwa yo pi lontan. Sitiasyon politik nan peyi-an te jwe yon gran rôl nan desizyon moun yo paske si genyen yon estabilite nan peyi-an moun yo pi dispozé investi a yon to interé ki pi piti paske yo kap genyen mwens chans pou yo pedi kob yo. Etid sila montre tou, an plis bwa te itilizé pou fe kay e pou brilé, yo itilizé'l pou yon bann lot bagay enpotan nan economi peyi d'Ayiti, kom ekzanp, pou fe meb ak bebel an bwa.
