Influence of 2 sowing dates on agro-morphological parameters

Sweet-stem sorghum[Sorghum bicolor(L.) Moench] is a plant traditionally grown around concessions in BURKINA FASO. Notwithstanding its low exploitation in Burkina Faso, sweet stem sorghum is full of potentialities, especially linked to its high accumulation of sugars in its stems and the quality of its fodder. The aim of this study was to determine a favorable sowing period for optimum expression of the agromorphological traits of sweet-stem sorghum and their response to variation in photoperiod. Thus, 29 genotypes from the gene bank of the Biosciences Laboratory of JOSEPH KIZERBO University were evaluated using 27 variables, including 07 qualitative and 20 quantitative variables in a Fisher block design with three replications. This study showed that all 07 qualitative variables and 02 quantitative variables, notably peduncle length and internode length (LPE, LOE), were not influenced by sowing date. However, 18 quantitative variables were influenced by sowing date.
