Climate variability has been and continues to be the main source of food fluctuations. This variability threatens the production of cash crops such as maize (Zea mays L). Maize is a cereal and has become one of the main agricultural crops in Côte d’Ivoire. The objective of this study is to determine the agro-morphological characteristics of three (03) varieties of maize (EV 8728, GMRP / 18 and MDJ) which have undergone irradiation with gamma radiation (0, 100, 200 and 300 grays) to induce mutations. The agro-morphological evaluation was carried out in a completely randomized block device. morphological characters selected from the descriptors of maize were used in this study. The descriptive analysis revealed a significant diversity between the treatments. The comparison between all the agro-morphological characters and the different treatments showed that the treatments EV8728_0 and EV8728_100 Gy had the best characteristics of ears and grains and the treatment MDJ_200 had the best vegetative characteristics.

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.

Face à un appauvrissement des sols et une irrégularité des pluies du fait du changement climatique, une étude a été entreprise sur la culture du maïs au Centre-Nord de la Côte d’Ivoire. Elle avait pour objectif d’évaluer l’influence de quatre types de fumures sur le potentiel agronomique de deux génotypes de maïs (Zea mays L.) en cas de contrainte hydrique de fin de cycle et d’infertilité des sols. Le dispositif expérimental a été un split-plot, dont le premier facteur a été les fertilisants et le second, la variété. Les résultats ont montré que les fumures ont influencé les durées des phases végétative et reproductive en plus du rendement. Les fumures fiente de poulet et déjection de boeuf ont permis d’obtenir un rendement qui est égal à six fois celui obtenu avec le témoin de la variété à grain noir malgré la contrainte hydrique. Aussi, la fumure fiente de poulet a eu une tendance à réduire le cycle de culture et favoriser une meilleure croissance et un bon développement des plantes. L’utilisation de ces fumures en culture du maïs, pourrait constituer une alternative aux conséquences drastiques du changement climatique. © 2020 International Formulae Group. All rights reserved.

Its objective was to assess the influence of four types of manure on the agronomic potential of two maize genotypes (Zea mays L.) in cases of water stress and soil infertility. The experimental set-up was a split-plot, the first five-level factor being fertilizers and the second two-level factor being variety. Observations were made on phenology, growth parameters and yield. The results showed that manure influenced vegetative and reproductive time, growth parameters and yield. In terms of yield, chicken droppings and beef droppings were the most effective. They yielded six times the yield obtained with the black-grain variety control despite the water constraint at the end of the cycle. Also, chicken manure has had a tendency to reduce the growing cycle and promote better growth and plant development. The use of these manure in maize cultivation could be an alternative to the drastic consequences of climate change. © 2020 International Formulae Group. All rights reserved.
