Mungbean ( Vigna radiata (L.) Wilczek) is an important source of nutrients and income for smallholder farmers in East Africa. Mungbean production in countries like Uganda largely depends on landraces, in the absence of improved varieties. In order to enhance productivity, efforts have been underway to develop and evaluate mungbean varieties that meet farmers’ needs in various parts of the country. This study was conducted at six locations in Uganda, to determine the adaptability of introduced mungbean genotypes, and identify mungbean production mega-environments in Uganda. Eleven genotypes (Filsan, Sunshine, Blackgram, Mauritius1, VC6148 (50-12), VC6173 (B-10),Yellowmungo, KPS1, VC6137(B-14),VC6372(45-60),VC6153(B-20P) and one local check were evaluated in six locations during 2013 and 2014. The locations were; National Semi Arid Resources Research Institute (NaSARRI), Abi Zonal Agricultural Research and Development Institute (AbiZARDI),Kaberamaido variety trial center, Kumi variety trial center, Nabuin Zonal Agricultural Research and Development Institute (NabuinZARDI), and Ngetta Zonal Agricultural Research and Development Institute (NgettaZARDI). G × E interactions were significant for grain yield. Through GGEBiplot analysis, three introduced genotypes (Filsan, Blackgram and Sunshine) were found to be stable and high yielding, and therefore, were recommended for release. The six test multi-locations were grouped into two candidate mega-environments for mungbean production (one comprising of AbiZARDI and Kaberamaido and the other comprising of NaSARRI, NabuinZARDI, Kumi, and NgettaZARDI). National Semi Arid Resources Research Institute (NaSARRI) was the most suitable environment in terms of both discriminative ability and representativeness and therefore can be used for selection of widely adaptable genotypes.

Fondé sur l’analyse des données produites par l’enquête « 1-2-3 » de 2012 en République Démocratique du Congo, cet article propose une approche quantitative de l’automédication. Il fait apparaître, le caractère relativement circonscrit de cette pratique dans les déclarations des individus confrontés à un épisode de maladie et tente de rendre compte des choix qui les guident : consulter un professionnel de santé, affirmer recourir à l’automédication, s’abstenir de se soigner ou recourir à l’automédication par défaut. La construction d’un modèle logistique multinomial non-ordonné permet à cet égard de comparer les déterminants de ces décisions, considérées sous la forme d’une double alternative : consulter ou recourir à l’automédication, et, pour ceux qui ne sollicitent pas un professionnel de santé, s’automédiquer ou s’abstenir de toute démarche thérapeutique. L’article pointe ainsi les contraintes (économiques, géographiques, sociales et culturelles) qui pèsent sur ces choix tout en soulignant comment les individus cherchent à s’en affranchir.
