“…Grain weight ranged from 303,29g to 444,9 g/m² with an average yield of 2.65 t/ha. These results are similar to those of Kouressy et al (2020) 16 where the mean grain yield of improved sorghum varieties (2560 kg/ha) is significantly higher than that of local varieties (1416 kg/ha). The difference between the grain yield of the L2 lineage with "Tiéblé" was greater than the DAP trial.…”

Sorghum (Sorghum bicolor) constitutes a food source for millions of people. Nowadays, sweet sorghums have the same interest as sugarcane. Traditional sweet sorghums have a high level of juice and sugar but a low grain yield. New sweet sorghum varieties have been developed by ICRISAT. In order to evaluate the effect of phosphorus on some agronomic and biochemical parameters of these new varieties, a study entitled "Characterization of new sweet sorghum varieties (Sorghum bicolor (L.) Moench) for their grain and sugar yield under two growing conditions in the Sudano-Sahelian zone of Samanko, Mali" was carried out. The trial was set up in an alpha lattice design with 2 replications. The treatments consisted of 48 sweet sorghum varieties, with 3 grain varieties as controls. Observations focused on agro-morphological parameters and sugar yield components. The results showed a high significance difference between lines for all variables measured except vigor at emergence. On soil with DAP application, 50% of the lines with a cycle of 263 to 273 Julian days had a grain yield higher than 2 t/ha. Only one line (L17) was earlier and more stable in both environments with a cycle of 271 to 273 Julian days. On soil without DAP application, only line L40 had an average yield gain of 2t/ha above the local control (Tieblé). The best performances in sugar concentration were obtained in High-P with 10 lines whose Brix varied from 18% to 20.25% and 15.3% to 17.7% in Low P.

“…If farmers intend to adopt it in these areas, they could mitigate its impact by reducing the depth of the pits to prevent suffocation of the plants. As observed in the course of this study, grain yield varies according to factors such as the sowing date, variety, and pre-harvest bird attacks (Kouressy et al, 2020). In this respect these authors obtained a yield of 3.500 kg.ha -1 for the improved variety Wassalen much higher than ours which was greater than that of the Gnognéfing variety (1.124 kg.ha -1 ).…”

“…Additionally, the amount of water received during the season and the duration of rainfall cessation had an impact on straw mass. A study on sorghum breeding in Mali also noted a yield decrease from the first to the second year (Kouressy et al, 2020). Biomass was between 7 and 11.9 t.ha -1 in year 1 and between 2.9 and 7.6 t.ha -1 the following season depending on the variety.…”

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 and information is not available on how to optimize yields for heirloom variety. To improve their economic and environmental sustainability, Mali farmers need to understand how to invest their limited resources. In many situations this involves the use of open-pollinated varieties that have a range of tillering capabilities. This study determined the best population density and nitrogen (N) fertilization combinations for eight locally available sorghum varieties. The research was conducted in 2018 and 2019 and the experimental design was split-split-plot randomized block, the treatments were two plant densities (26,600 and 53,300 plants ha -1 ), three N levels (0 kg ha -1 , 89 kg ha -1 , and 178 kg ha -1 ), and eight varieties that had a range of tillering characteristics. Each treatment was replicated three times and six of the varieties were open pollinated. Results showed that each variety had a different yield response to plant density and N rate. For example, the tall guinea (hybrids FADDA and PABLO) and the short durra-caudatum A12-79 cultivar produced higher yields when planted at 53,300 plants ha -1 and Abbreviations: D1, 26,600 plants ha -1 ; D2, 53,300 plants ha -1 ; MRR, marginal rate of return; N0, nitrogen rate of 0 kg ha -1 ; N1, nitrogen rate of 89 kg ha -1 ; N2, nitrogen rate of 178 kg ha -1 .This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.
