Phaseolus lunatus is a legume rich in protein and essential amino acids, with a notable morphological diversity that influences its floral phenology. The aim of this study was to evaluate the flowering period of four morphotypes and to determine the duration of flower opening. The experiments were carried out at the Université Jean Lorougnon Guédé in Daloa, Côte d’Ivoire. The experimental set-up used was a complete block with 10 plants per morphotype. The results revealed significant variability between morphotypes. Morphotype 3 showed early flowering (79 days), while morphotype 2 was the latest (137 days). Analysis of floral morphology using an optical microscope revealed significant differences between morphotypes in terms of the number of flowers opened and aborted. This study underlines the importance of understanding floral phenology for optimizing P. lunatus production and guiding varietal selection. The variability observed highlights the potential for genetic improvement, in order to develop better-performing varieties that are better adapted to changing climatic conditions.
The study was made in Manfla. Optimization of sowing calendar corn and Bambara groundnut (Vigna subterranea) was made. This study aimed to evaluate the effect of corn seeding calendar on agronomic parameters of voandzou. A series of pure cultures device of offset and simultaneous planting seedling was taken. These provisions are voandzou sown 15 days before maize (M15JAPV), voandzou sown 30 days before maize (M30JAPV), voandzou sown 15 days after maize (M15JAVV) voandzou sown 30 days after maize (M30JAVV) and simultaneous sowing. The production of each association system was evaluated on the basis of measurements on the yield and yield components. Thus, it is noted that the most important voandzou production is obtained when voandzou sown 15 and 30 days before maize maize.
