En Haïti, l’amélioration des performances du secteur agricole est limitée par de nombreux facteurs dont la diminution progressive de la fertilité des sols. Le prix des fertilisants chimiques est en hausse sur le marché alors que les déchets organiques, potentiellement valorisables, ne sont pratiquement pas valorisés. 
En vue de contribuer à l’amélioration durable de la fertilité des sols en Haïti, plus particulièrement les sols maraîchers, par la valorisation des déchets organiques et la réduction de l’utilisation des engrais chimiques dans l’agriculture, il a été réalisé dans la zone périurbaine de Ouanaminthe (Nord-Est, Haïti) une étude dont les objectifs spécifiques ont été de tester l’efficacité du fumier de volaille frais (T2) et du fumier de volaille composté (T3) sur la croissance et le rendement de l’amarante (Amaranthus cruentus L.), comparativement au fertilisant chimique de formulation 15-15-15 (T4) et à des parcelles non fertilisées (T1). 
Cette étude a été réalisée en plein champ entre le milieu du mois d’Avril et le début du mois de Juin 2022. Le dispositif expérimental en Carré Latin constitué de quatre (4) traitements, quatre (4) lignes et de quatre (4) colonnes a été utilisé. Des échantillons de sol et de fumiers de volaille (frais et composté) ont été prélevés et analysés. Les doses appliquées ont été calculées en tenant compte des besoins d’exportation de l’amarante en Azote (125 kg/ha) pour des rendements de l’ordre de 20 t/ha. La cendre de bois a été utilisée pour équilibrer les apports des fumiers de volaille (frais et composté) en phosphate et en potasse. Les données ont été analysées sur le logiciel R suivant l’ANOVA à un facteur et le test de Tukey au seuil de 5% de probabilité. 
Les principaux résultats obtenus ont montré que les fumiers de volaille (frais et composté) ont globalement entrainé une amélioration de la croissance et du rendement de l’amarante, comparativement aux parcelles non fertilisées sur lesquelles la croissance et le rendement ont été un peu faibles. Par ailleurs, le rendement obtenu avec le fumier de volaille frais (2,42 ± 0,07 kg/m2) n’a pas été significativement différent du rendement obtenu avec le fertilisant chimique (2,68 ± 0,07 kg/m2). La hauteur et le diamètre obtenus avec le fumier de volaille frais (57,17 ± 2,89 cm et 12,33 ± 0,48 mm) n’ont pas été non plus différents de ceux obtenus avec le fertilisant chimique (70,78 ± 2,89 cm et 14,66 ± 0,48 mm). Cependant, la hauteur et le rendement obtenus avec le fumier de volaille composté (54,31 ± 2,89 cm et 2,08 ± 0,07 kg/m2) ont été significativement inférieurs à la hauteur et au rendement obtenus avec le fertilisant chimique (70,78 ± 2,89 cm et 2,68 ± 0,07 kg/m2). In Haiti, improving the performance of the agricultural sector is limited by many factors including the gradual decline in soil fertility. The price of chemical fertilizers is rising on the market while organic waste, potentially recoverable, is practically not recovered. 
In order to contribute to the sustainable improvement of soil fertility in Haiti, more particularly market garden soils, through the recovery of organic waste and the reduction of the use of chemical fertilizers in agriculture, it was carried out in the peri-urban area of Ouanaminthe (North-East, Haiti) a study whose specific objectives were to test the effectiveness of fresh poultry manure (T2) and composted poultry manure (T3) on the growth and yield of amaranth (Amaranthus cruentus L.), compared to chemical fertilizer formulation 15-15-15 (T4) and unfertilized plots (T1). 
This study was carried out in the open field between the middle of April and the beginning of June 2022. The experimental device in Latin Square consisting of four (4) treatments, four (4) lines and four (4) columns were used. Soil and poultry manure samples (fresh and composted) were collected and analyzed. The doses applied were calculated considering the export requirements of amaranth in nitrogen (125 kg/ha) for yields of the order of 20 t/ha. Wood ash was used to balance the contributions of poultry manure (fresh and composted) in phosphate and potash. Data were analyzed using R software using one-way ANOVA and Tukey's test at the 5% probability threshold. 
The main results obtained showed that the poultry manures (fresh and composted) generally led to an improvement in the growth and yield of amaranth, compared to unfertilized plots on which growth and yield were somewhat weak. Moreover, the yield obtained with fresh poultry manure (2,42 ± 0,07 kg/m2) was not significantly different from the yield obtained with the chemical fertilizer (2,68 ± 0,07 kg/m2). The height and diameter obtained with fresh poultry manure (57,17 ± 2,89 cm and 12,33 ± 0,48 mm) were also not different from those obtained with the chemical fertilizer (70,78 ± 2,89 cm and 14,66 ± 0,48 mm). However, the height and yield obtained with composted poultry manure (54,31 ± 2,89 cm and 2,08 ± 0,07 kg/m2) were significantly lower than the height and yield obtained with the chemical fertilizer (70,78 ± 2,89 cm and 2,68± 0,07 kg/m2).
