Suitability and Appraisal of Surface Water for Irrigation Purpose

Abstract

Abogunde village relies heavily on river water for crop irrigation, and water quality is critical for maximum crop production. Samples of Abogunde river water were collected during the dry and rainy seasons and analyzed for various parameters. The results indicated that the pH range was slightly acidic in the dry season but more alkaline during the rainy season. Calcium (Ca2+), magnesium (Mg2+), potassium (K+), sodium (Na+), bicarbonate (HCO3-), phosphate (PO3-P), electrical conductivity (EC), nitrate (NO3-N), sulphate (SO42-) and total dissolved solids (TDS) were within the recommended limits set for irrigation standard water, indicating that the river water in Abogunde village is suitable for irrigation purposes. The water quality indicators, including MAR, SAR, SSP, KR, PS, PI, RSC, and TH, were all within safe limits for both seasons. Overall, the findings suggest that the Abogunde river water is suitable for irrigation purposes, and farmers in the area can use it to grow their crops without adverse effects. However, continuous monitoring of water quality is essential to ensure that it remains within safe limits, and appropriate measures should be taken to address any issues that may arise.
