Salinity Levels of Irrigation Water for Bakori, Jibia and Mairuwa Irrigation Schemes in Katsina State, Nigeria

Abstract

Irrigation water quality has great significance especially in arid and semi-arid regions and it is based on salinity and permeability. In this research, water samples were collected in a dry season from Bakori, Jibia and Mairuwa irrigation schemes in Katsina State Nigeria. Electronic Conductivity (EC), Total Dissolved Solids (TDS) and Total Hardness (TH) test in accordance with APHA 2005, standard methods for examination of water and wastewater were conducted in order to determine the salinity level in irrigation water. The result shows that average values of EC are 6.18, 6.22 and 2.51dS/m for Bakori, Mairuwa and Jibia respectively while TDS values are found to be 297.3, 297.6 and 119mg/l for Bakori, Mairuwa and Jibia. The TH values for Bakori and Mairuwa are 97.3 and 98.2mg/l while that of Jibia was recorded as low as 61.3mg/l.
