Abstract
This study examines the Effect of Climate on the growth and yield of Sorghum at Wailo, Ganjuwa Local Government Area, Bauchi State of Nigeria. Correlation and regression analysis were used to determine the relationship between Sorghum yield and weather elements for different phonological stages of the crop’s growth. The results of the correlation analysis show that at pre-sowing stage, the total rainfall is found to be significantly and positively correlated with yield at 5% significant level. Relative humidity at flowering stage also shows significant and positive correlation at 1% significant level with the final yield. At total growing season, seasonality of rainfall is significantly and positively correlated with the final yield at 5% significant level, which is seasonality of rainfall. Multiple regression analysis shows that these three elements (total rainfall, relative humidity and seasonality index) accounted for 76.7% of the variation of Sorghum yield at Wailo. The implications of the results are discussed with respect to sorghum farming in the study area
