This study was conducted to evaluate the morphological and agronomic performance of ten varieties of sweet potato grown in Bongor in Chad during the dry season. The average length of internodes of the main stem and means the collar diameters were measured and maximum growth rates associates were determined, the length and diameter of tuber were measured, the number of tuber per plant were recorded tuber yield, the diameter/length ratio of the tuber, the average weight of tuber and dry matter aboveground biomass were determined. The results, it appears that varieties BF 59 and BF 40 have the longest and varieties BF 108 and TIB have diameters in the larger collar internodes. The highest growth rates were noted between the 37th and 51st JAP and between the 23rd and 72nd JAP respectively for the length of internodes and the collar diameter. For agronomic parameters, variety BF 108 was more effective for most of the studied parameters. This variety seems interesting for the selection of work.
The objective of this study was to highlight the physiological, morphological and agronomic performance of varieties and descendants of sesame (Sesamum indicum) grown in Burkina Faso.
Experimentation was conducted at the Gampela educational agro station located at 12
