La qualité des noix brutes de cajou est un facteur déterminant dans la fixation de leurs prix d’achat et de vente. L’objectif de cette étude est d’évaluer la qualité des noix de cajou afin de contribuer à l’amélioration des traitements post-récoltes desdites noix et la revalorisation des revenus des planteurs. Sur 208 échantillons du département de Korhogo, les paramètres de qualité ont été déterminés selon la norme ivoirienne PNI 4595. La valeur minimale des taux d’humidité moyens est 5,6±1,4% tandis que la valeur maximale est 5,8±1,8% avec une moyenne globale de 5,7±1,8%. Les grainages moyens sont 182±13 noix/kg, 179±13 noix/kg, 180±15 noix/kg, 179±12 noix/kg et 181±12 noix/kg respectivement pour les zones 1 ; 2 ; 3 ; 4 et 5 avec une valeur moyenne de 180±13 noix/kg. Concernant les taux de défauts moyens, ils varient entre 11,96±4,59% et 13,90±5,65% avec pour moyenne générale 13,10±5,08%. Les valeurs de l’out-turn oscillent entre un minimum de 44,87±3,65 lbs et un maximum de 45,90±2,62 lbs avec une moyenne globale de 45,42±2,78 lbs. Les proportions de noix de bonne qualité sont 54%, 66%, 64%, 64% et 69% respectivement pour les zones 1 ; 2 ; 3 ; 4 et 5 avec une proportion globale de 64%. La qualité des noix de cajou produites dans le département de Korhogo, est moyennement bonne. English title: Assessment of the quality of cashew nuts (Anacardium occidental L.) produced in the division of korhogo in Côte d’Ivoire The quality of raw cashews is a determining factor in setting their buying and selling prices. The aim of this study was to assess the quality of cashew nuts in order to contribute to the improvement of post-harvest treatments of said nuts and the revaluation of the income of the growers. On 208 samples, from the division of Korhogo, the quality parameters were determined according to the Ivorian standard PNI 4595. The minimum value of the average moisture contents is 5.6±1.4% while the maximum value is 5.8±1.8% with 5.7±1.8% as the overall average of the division of Korhogo. The average grainings are 182±13 nuts/kg, 179±13 nuts/kg, 180±15 nuts/kg, 179±12 nuts/kg and 181±12 nuts/kg respectively for zones 1; 2; 3; 4 and 5 with an average value of 180±13 nuts/kg. Concerning the average defect rates, they vary between 11.96±4.59% and 13.90±5.65% with the general average being 13.10±5.08%. The out-turn values fluctuate between a minimum (44.87±3.65 lbs) and a maximum (45.90±2.62 lbs). The average of this parameter in the division of Korhogo is 45.42±2.78 lbs. The proportions of good quality nuts are 54%, 66%, 64%, 64% and 69% respectively for areas 1; 2; 3; 4 and 5 with an overall proportion of 64%.

Aims: Maize (Zea mays L.) is a major staple food for millions of people in Côte d’Ivoire. Due                         to its high productivity and low cost of calorie it is preferred crop for food security of the                      country. Thus, this study was conducted to assess nutritive quality of maize produced and               stocked in five purposively selected regions of Côte d’Ivoire which represents five agroecological settings. Study Design: A total of 1500 samples of maize as grains, epis and spathes were collected at rate of 500 samples by region (Gbêkê, Poro, Hambol, Indénié-Djuablin and Gontougo) and sent to the laboratory in order to analyse their nutritional quality. Place and Duration of Study: This study was carried out during March 2016 to January 2017. The collected sample were carried out at the laboratory unit of Food Sciences and Biochemistry of the Félix Houphouët-Boigny University, Abidjan. Methodology: Proximate analyses were carried out using standard methods AOAC (2000). Results: The results show significant difference from the biochemical compositions of maize type and region. Mean value intervals were as follow: dry matter (85.83 – 91.42%), ash (1.19 - 2%), proteins (7.99 - 9.32), lipids (3.21 - 4.47), carbohydrates (71.80 - 77.94), starches (62.30 - 68.44%), fibers (5.03 - 5.83%), total sugars (2,13 - 2.99%), reducing sugars (0.33 - 0.66%), free fat acidity (1.86- 4.50%), peroxide value (1.34 - 3.07 meq O2/kg), iodine value (100.93 - 130.56 g I2/100 g), unsaponifiable (0.89 - 1.54%) and energy values (357.88 - 374.39 kcal). Conclusion: A significant variability from one region to another can be noticed at level of maize quality regardless the type of maize. The nutritive quality of maize seems to be tied to postharvest treatments (drying), type of storage (epis, grains and spathes) and structure of storage.

The study was conducted in Koffikro-Affema village located in the South-East of Côte d'Ivoire to assess the morpho-physical and chemical quality of soils under cocoa farm, for the management of early degradation of orchards. Representative soil samples were taken by horizon under degraded cocoa farms after a morpho-pedological characterisation. These samples were then analysed in the laboratory for fertility parameters. The results indicate that the cocoa farms have a high rate of degradation and the study made it possible to identify the soil characteristics associated not only with the degradation of cocoa trees, but also with the drop in yield. These are the rate of coarse grains greater than 50%, the low organic matter content (less than 3.5%), a very slow rate of mineralisation (C/N > 12), poor internal drainage and the acidic pH of the soil (4.4-5.5). The soils surveyed are highly desaturated to moderately saturated and the main characteristics of the absorbing complex indicate that they are unfavourable for cocoa. Indeed, these soils are deficient in K+ (<0.2 cmol/kg), Ca2+ (between 5.1 and 11.41 cmol/Kg) and assimilable Nitrogen (˂0.2 cmol/Kg). Similarly, the Mg2+/K+ ratio of less than 3 shows that they are magnesium deficient. The results also revealed an influence of the topographical position on the degradation of cocoa trees with, on the upper and middle slopes, strongly gravelly and poorly drained horizons, associated with the degradation of cocoa trees. On the other hand, on the lower slopes, these soils are deep, not gravelly, with good growth of cocoa trees and low yields.

Aims: The present study aims to evaluate the effect of some abiotic factors on the quality of seed germination of shea tree, a plant of great economic interest for the rural populations in Northern Côte d'Ivoire. Study Design: The trials were conducted in a nursery where two factors were considered. These were the substrate, with six modalities and shelter with two modalities. Six small pits, each of size 60 x 60 cm, surface 3600 cm2 and 15 cm of depth were dug and then filled with different substrates. Place and Duration of Study: The work was carried out in 2018 in the district of Korhogo in Northern Côte d'Ivoire. Methodology: Each treatment received 36 seeds of shea tree giving a total of 216 seeds per test. The seeds used were all dark brown, ellipsoid in shape with masses ranging from 10 to 11 g. The experiment was carried out with a total of 12 treatments, six under a greenhouse hermetically covered with transparent polyethylene plastic and six under a shade made up of a rack covered with maximum Panicum leaves.  Results: The first germination was observed at the level of the organic manure treatment at 6 months of degradation installed under the greenhouse (ManB_G = 28 days). The lowest final germination rate was obtained with the organic fertilization at 3 months of degradation installed under the shade (FGP ManA_S = 2.95%) while the highest was observed in the sawdust installed under the greenhouse (FGP S_G = 64.18%). Conclusion: It is concluded that for each substrate, soil or biowaste, the seeds of shea tree have a better ability to germinate under a greenhouse than under a shelter covered with straw.

Aims: To assess the effectiveness of triple bagging systems with or without Lippia multiflora leaves on the vitamin-quality of cowpea seeds during storage. Methodology: Cowpea seeds that have undergone any treatment were collected from producer in the southwest of Côte d’Ivoire. The fresh leaves of Lippia multiflora were collected and dried in sunlight for 7 days in center of Côte d’Ivoire. The storage bags used were obtained from the suppliers to Côte d’Ivoire in Abidjan. All this material was sent to the Laboratory of Biochemistry and Food Sciences, Felix Houphouet-Boigny University, Côte d’Ivoire to perform the experiment. Thus for the experiment realization, a central composite design (CCD) was used. The first factor of CCD consisted to six types of packaging, namely: one control with polypropylene bag (TST), one triple bagging batch (composed of 2 internal layers in independent high density polyethylene 80 mm thick and a woven bag polypropylene) without biopesticide (H0), and four batches (H1, H2, H3 and H4) containing respectively (0.7%; 2.5; 4.3%; and 5%) biopesticide. The second factor, storage time, it included six periods of observation (0; 1; 2; 4.5; 7 and 8 months). HPLC techniques were used for the separation and quantification of β-carotene, α-tocopherol (vitamin E) and the water-soluble vitamins (thiamine, riboflavin, niacin, pyridoxine and folic acid). The estimated daily intake of folic acid (vitamin B9) was also evaluated for Ivorian adult of 70 kg. Results: The results of vitamin properties indicate a significant influence (P < 0.05) between the type of treatments and shelf life. Multivariate analysis results (PCA and AHC) indicate that the addition of at least 0.7% Lippia multiflora leaves in triple bagging systems makes preservation more efficient and preserves the vitamin quality of the cowpea seeds during 8 months. The contribution to meeting vitamin B9 requirements is palpable when cowpea seeds are stored for up to 8 months in the triple bagging systems associated with the biopesticide. Conclusion: Cowpea seeds storage in triple bagging systems with Lippia multiflora leaves appears as a method of effective and inexpensive conservation to ensure the vitamin-quality of cowpea.

Low quality of care is a significant problem for health systems in low-income and middle-income countries (LMICs). Policymakers are increasingly interested in using performance-based financing (PBF), a system-wide provider payment reform, conditioned on both quantity and quality of performance, to improve quality of care. The health system context influences both the design and the implementation of these programmes and thus their effectiveness. This study analyses how context has influenced the design and implementation of PBF in improving the quality of primary care in one particular setting, Cote d’Ivoire, a lower-middle income country with some of the poorest health outcomes in the world. Based on literature, an analytical framework was developed identifying five pathways through which financial incentives can influence the quality of primary care: earmarking, conditioning, provider behaviour, community involvement and management. Guided by this framework, semistructured interviews were conducted with policymakers and providers to diagnose the context and to assess the links between financing and quality of care at the primary care level. PBF in Cote d’Ivoire was found to have increased data availability and quality, facility-wide and disease-specific inputs, provider motivation and management practices in contracted facilities, but had limited success in improving process and outcome measures of quality, as well as community involvement and the provision of non-incentivised services. These limitations were attributable to a centralised health system structure constraining the decision space of health providers; financing and governance challenges across the health sector; and shortcomings with regard to the design of the PBF quality checklist and incentive structures in Cote d’Ivoire. In order to improve the quality of primary care, health sector reforms such as PBF should incorporate the organisational and service delivery context more broadly into their design and implementation, as is the case in other countries.
