This research was done in order to assess the effects of seasonal flooding on irrigation water quality of the floodplains of Wukari Area of Taraba state. Water samples were collected from five different flood plain locations (Nwuko, Tsokundi, Rafin-Kada, Gidan-Idi and Gindin-Dorowa) in 2016 and 2017. Completely randomized design (CRD) was employed replicated three times. The results obtained were subjected to analysis of variance and means separated using F-LSD test at P ≤ 0.05. The results of the water quality analysis showed that all the determined parameters were significantly different at the different sample locations, except water pH of the year 2016 which was not significantly different at the different sample locations. The results show that the flooded water could be used for irrigation since they were found to be relatively safe and hence required little or no treatment for soluble salts. Water from flooding within the Wukari Floodplains is recommended for supplementary irrigation.

Irrigation Water were sampled from some major rivers in the mid-section of Benue Trough for two consecutive years, 2011 and 2012 and analysed for some metals contents and physicochemical properties. The results showed that irrigation water were slightly (pH 6.5) to moderately (pH 5.5) acidic and good for irrigation with minimal or no liming. Very low pH delays nutrients uptake by plants and therefore plant metabolism. Levels of total soluble salts, Mg
