Abstract: To tackle the feed shortage, fodder oat is one of improved fodder crops highly recognized mainly in the highland areas. However, the performance of fodder oat sown in different time vary in yield and quality parameters and hence identifying the proper time of sowing date is critical for production of high biomass and quality fodder oat. Thus, the study was conducted to determine the appropriate sowing time of oat. Accordingly five sowing times (mid-June, late June to early July, mid-July, late July to early August and mid-August) were laid out in Randomized Complete Block Design (RCBD) with three replications. The results indicated that sowing time had a significant (p < 0.05) effect on plant height and number of tillers per plant. Leaf to stem ratio was significantly (p < 0.05) affected due to sowing time only at Kofele site. Dry matter (DM) and seed yield were also significantly (p < 0.05) different among sowing time at both sites with the maximum yield recorded at early sowing time. The maximum DM yield (7.5 t/ha to 13.9 t/ha) was recorded from oat sown in mid-June followed by oat sown in late June to early July (8.0 t/ha to 10.8 t/ha) at both sites, while the lowest DM yield (1.13 to 3.3 t/ha) were obtained from oat sown in mid-August. Likewise, the highest seed yield (20.1 to 22.8 qt/ha) were recorded from oat sown in mid-June followed by (18.9 qt/ha to 21.8 qt/ha) in late June to early July while the least seed yield (4.1 qt/ha to 4.8 qt/ha) produced from oat sown in mid-August. The higher yield in earlier sowing time may be due to the good weather conditions that prevailed during the earlier sowing period which favors for plant height and number of tillers per plants. On the other hands, ADF and CP contents of oat were significantly (p<0.05) influenced by sowing times. Therefore, it can be concluded that sowing oat from mid-June to early July is recommended to maximize both the yield and nutritive value of oats in the study areas. To minimize the risks of lodging while sustaining high yield performance, further study is required on agronomic management and to select lodging tolerant oat varieties.

Abstract: The security context in the West African sub-region has been deteriorated significantly in recent years due to the Jihadist threat. This has prompted the Government of Côte d'Ivoire to integrate nuclear security measures into the overall security of the 2023 African Cup of Nations as this Major Public Event where a large number of people were expected to gather, could be a great attraction for terrorist groups. This Event took place in five (05) major cities of Côte d'Ivoire and nuclear security concerned all the competition stadiums and the other strategic locations such as airports, Fan zones, car parks, VIP hotels, training stadiums, etc. However, for the purposes of this report, we are only interested in the nuclear security system deployed at the Alassane Ouattrara Olympic Stadium in Ebimpé where 10 competition matches were played, including the opening and the final matches of the tournament. We first highlight the importance of the International Atomic Energy Agency training program (Train-the-Trainers courses) for national stakeholders which has enabled us to achieve our objectives. We Then present the different component of nuclear security that have been taken into account, the good practices applied and the weaknesses or the unexpected problems identified. Finally, the lessons learned and the prospects for a sustainable implementation of nuclear security during all major public events that will take place in Côte d'Ivoire are presented. It should be noted that all detection devices operated correctly and no nuclear security events were reported.
