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.
