Planting Date and Genotype Effect On Morpho-agronomic Traits of Burkina Faso Sweet Grain Sorghum

Sweet grain sorghum is an under-exploited crop mainly grown around dwelling houses. Its production faces harsh environmental conditions. This study aims to assess sowing date effect on morpho-agronomical traits of sweet sorghum. Thus, 30 genotypes were assessed under 2 planting dates (June 26 and July 20) 24 days apart in a Randomized Complete Block Designs with 3 replications using 10 traits. The results showed significant most the traits, except internode length. All sensitive photoperiod variation by reducing their sowing-flowering cycle from 08 20 days, size yield at second date. Delayed also resulted decrease plant height (66.4 cm), 100 weight (8.3%), panicle (16.84%) per (18.93%). expressed differential sensitivity mean coefficient 0.59. Finally, clustered flowering all between September 11 27 was observed for both dates. These could be exploited breeding programme definition cropping calendar.
