Plant density and nitrogen fertilization optimization on sorghum grain yield in Mali

چکیده
Sorghum [Sorghum bicolor (L.) Moench], a staple food crop in Mali, has low yields for several reasons including that many farmers do not have the financial resources to purchase state-of-the-art genetics and fertilizers information is available on how optimize heirloom variety. To improve their economic environmental sustainability, Mali need understand invest limited resources. In situations this involves use of open-pollinated varieties range tillering capabilities. This study determined best population density nitrogen (N) fertilization combinations eight locally sorghum varieties. The research was conducted 2018 2019 experimental design split-split-plot randomized block, treatments were two plant densities (26,600 53,300 plants ha–1), three N levels (0 kg ha–1, 89 178 had characteristics. Each treatment replicated times six open pollinated. Results showed each variety different yield response rate. For example, tall guinea (hybrids FADDA PABLO) short durra-caudatum A12-79 cultivar produced higher when planted at ha–1 fertilized with N2D2 treatment. guinea-caudatum improved C2_007-03 C2_075-15 caudatum GRINKAN SOUMBA optimum seeding rate (N1D2). local TIEBILE highest observed it seeded 26,600 ha–1. Grain increase associated components growth traits studied. Panicle numbers per square meter chlorophyll index grain hybrid. number panicle 1,000 weight involved increasing Nitrogen planting combination terms varied Moench] Knowledge will help producers decide which option promote booster production Mali.
