Abstract

Aim: The main objective of this study was to assess quality of water for irrigation and the impact of associated hazards on soil features and crop yields.

Materials and Methods: A total of 1054 statistical data of primary indices; Total Dissolved Salts (TDS), Electrical Conductivity (EC), sodium adsorption ratio (SAR), Exchangeable sodium percentage (ESP), and specific ion toxicity were collected from perceptible researches publications during 2010 –2020.  Salinity, sodicity and specific ion toxicity status of the wells and irrigated soils were evaluated using the guideline specifications of the United Nations Food and Agricultural Organization (FAO).

Results: Most of irrigation scheme in the study area falls within slight to moderate hazard categories. Irrigated soil salinity evaluation showed potential hazards can be expected for sensitive and moderately sensitive irrigated crops and thus, an apt mitigation strategy including selection of tolerant crops is becoming imperative.

Conclusion: It was concluded that outcome  may  play vital roles  in designing  efficient irrigation  systems  and management practices  for sound land use and to sustain agricultural  productivity.
