Abstract: This study was conducted in the Central region of Burkina Faso in 2014 and 2015, to test the
options of sorghum adaptation strategies, which are able to enhance sorghum productivity,
contributing to food security. Two experiments using a randomized split-plot design were set up
under two dry sowings during hot (March) and cold (October) seasons respectively. These
experiments were subjected to two water regimes (50% and 100% potential evapotranspiration,
two nitrogen levels (0 and 60N) and two sorghum varieties (local improved, Kapelga and high
yielding, Sariaso 14). The treatments were assessed for the varietal performance under irrigated
sorghum production. By these experiments, under the cold dry experiment sorghum reproductive
cycle was shortened and grain yield and harvest index improved. The study underscored the
outperformance of the variety Sariaso 14 over that of the Kapelga variety regardless of the
management options and growing conditions. Sariaso 14 was 74% more improved than Kapelga.
In addition, it was found that under irrigation stress condition and optimum irrigation, nitrogen
application did not significantly improve the yield of Kapelga .This study would therefore help
farmers to decide how to manage Kapelga in irrigated systems in case where the high yielding
Sariaso 14 is not accessible. |
