Abstract
A research was conducted at Botanga irrigation area to assess the levels of selected irrigation water quality parameters. The parameters considered were pH, electrical conductivity (ECw), total dissolved solids (TDS), calcium (Ca), magnesium (Mg), sodium (Na), sodium adsorption ratio (SAR) and bicarbonate (HCO3-). Water samples were collected from the dam, main canal and laterals for analysis. The results showed that all the selected irrigation water quality parameters were found with the maximum allowable limit, and the value of HCO3- was low to precipitate CaCO3 in the water thereby increasing the value of Na and SAR. The water was therefore suitable for irrigation.
