Abstract

This paper analyzes rainfall variability in Argungu area. Data for half climatic year 1995-2012 were obtained from Argungu station of Kebbi Agriculture and Rural Development Authority. Analysis of variance (ANOVA) was used to analyze the data. The results show that there is statistically significant difference in annual rainfall over the years. Analysis further revealed that the month of August, 2010 has the highest rainfall amount of 1066mm with the year 1996 receiving the least annual rainfall amount within the period under study respectively.
