“…Yet, there is, till now, no study conducted on phenotypical diversity of Haitian MO. Study conducted on Haitian MO are mainly related to fungal and aflatoxins contamination of seeds (Aristil et al, 2017;Aristil et al, 2019). The present survey was conducted to evaluate the morphological/phenotypical diversity of Haitian MO.…”

Moringa (MO) is a plant with great nutritional value distributed in almost all subtropical and tropical countries including Haiti. MO is relatively present in all departments of Haiti. But till now, there are no data available for the phenotypical diversities of Haitian MO. The current survey is aimed at evaluating the morphological diversity of Haitian MO. From June to September of the 2018 year, 90 samples of MO were collected in the 10 departments of Haiti. Characters registered per plant were submitted to statistical analysis using IBM SPSS, version 22.0. Results revealed that Haitian MO grain yield (GY) were ranging from 0.20 to 3.26 t/ha. MO from Grand’Anse and South are significantly more yielded than the other districts (p< 0.05). MO grain yield was positively related to all registered characters. The two maximal GY correlations were observed mainly with the number of branches plant (? =0.74; p<0.001) and the number of pods per branch (? =0.60; p<0.001). Haitian MO was classified into two separate clusters. MO of South, Southeast and Grand’Anse departments formed one cluster and the other departments constituted the largest one. The greatest genetic diversity was detected in MO from Southeast and West departments. Crossing materials from Southeast and West department is well recommended for creating possibly new accessions. The additional investigation regarding molecular classification is deeply required for better understanding of the genetic diversity of Haitian MO.

“…PL and CP were in cm and a scale meter was used for registering the last two traits. The grain yield (GY) of investigated MO tree was calculated by: GY (t/ha) = M1G (g) x NGP x NPB x NBP x 625 ÷ 1000,000 (Aristil, 2019).…”

“…By the process of decomposition and mineralization, nutrient elements provides to different types of fertilization such as Phosphorous, Nitrogen which are available for the growth of plants [18,17]. In the context of soils poverty in rural zone, the uses of organic matter could facilitate the penetration of plant-roots, circulation of air or water in the soil and the formation and maintenance of Argilo-humic complexe of soil [20,21].…”

“…Similarly works of Tshibingu et al [14] proves that the diameters of plants are higher on fertilized plots of Maize compared to the check. According to the works of Aristil [21], a diameter of plants of Sorghum related to the fertilization varies according to the types of fertilizers applied. The supplies of organic matter on soil permit to stimulate the activities and the diversity of soil micro-organisms [22].…”

Aims: Study aims to evaluate the effect of chicken manure and mycorrhiza levels as fertilizers on vegetative growth and on phenological stages of Sorghum in Far North Cameroon. Place and Duration of Study: The study was conducted in the Valorization Station of Agricultural Research (PSAR) of Yagoua. Methodology: For this study, variety S-35 of Sorghum have used. Three levels of fertilization were used to evaluate germination rates, vegetative growth and phenology of this variety. The levels of fertilizers applied were 20 g of mycorrhiza, 50 g of organic manure and 20+50g of effect combined mycorrhiza+organic manure in comparison to the check (0g). The experimental design was the randomized block design with 3 replications. After evaluation of germination rates in the farm, we had evaluated the height, diameters and precocity of plants. Results: Uses of different levels of fertilization on germination rates were important for all the levels of fertilizers compared to the control (27. 5 %). It’s varying from 52.5 % for the chicken manure, followed by the effect of combined treatments (45 %) and bio-fertilizers with 67 %. Compared to the check, the use of chicken manure as fertilization was most significant (P<0.05) on the height of plants during the vegetative growth. The diameters of plants according to the different treatments were most significant (P<0.05) respectively by the supplies of chicken manure, the effect of both treatments (mycorrhiza+chicken manure) and mycorrhiza treatment. Theses different levels fertilization was influenced the phenological stages of plants especially first flowering of plants days after sowing. Flowering of plants at 50 % was most favorable for the treatments based on the uses chicken manure and the combined effect of treatments (mycorrhiza+chicken manure). Conclusion: Uses of chicken manure and mycorrhiza as fertilizers on Sorghum were significant to the vegetative growth and flowering stages of plants. Levels of chicken manure had positive effect on plant height. Plants diameters were most positively affected by organic manure, mycorrhiza and the effect of both treatments during growing of plants.

Taro corm is consumed in Haiti as a sustain against malnutrition, but no study was so far reported about Haitian taro. An ongoing breeding program, aimed at supporting corm production, includes the present investigations on taro. Eleven taro accessions sampled in 9 departments of Haiti were tested at Torbeck from January to August 2018. Seven variables were considered and treated with SPSS. Significant (p < 0.05) differences appeared for three of the seven considered traits. Corm marketable yield varied from 2.97 to 12.79 t/ha (p<0.05), the locations with the largest yield being Coteaux (South department, 12.79 t/ha), Petite- Riviére de Nippes (Nippes department, 7.56 t/ha) and Jacmel (South East department, 7.01 t/ha). Corm marketable yield was significantly (p < 0.001) and directly related with weight of corm per plant (ρ = 0.999), leaf length (ρ = 0.924) and leaf width (ρ = 0.795). Haitian taro cultivars were divided in three separate clusters. The largest differences concerned taro accessions from Grande Rivière du Nord and Coteaux. The results of this study show that accessions from Coteaux, Petite Riviére de Nippes and Jacmel should be recommended in the plant selection program to increase corm production in Haiti.Keywords: Taro, marketable yield, diversity, cultivars, Haiti.
