ABSTRACT:

The study examined the relationship between Climatic variability and sorghum yield in Nigeria.The analysis was done on the data of sorghum yield and Climatic variability from1980 to 2021. The trends were shown during the rainfall season with the effect of climatic variability on sorghum production. It was revealed that sorghum production suffered significant yield reduction when the rains were high. Tests (unit and diagnostic) were conducted at the preliminary stage, with the usage of a time series variables. The adjusted R2 value of 86.62% suggested that rainfall, temperature and relative humidity jointly explain a significant part of the variation in Sorghum yield. The findings further showed that sorghum is a drought resistant crop in the study area; despite the decline in annual rainfall, sorghum yield was increasing as a result of other factors(-4.181885 temperature, and -177.8620 relative humidity). The study thus, recommended the provision of early warning weather information to farmers; use of climate-resilient varieties, high and early maturing cultivars and fertilizer management to improving the productivity of sorghum in the study area.
