| Summary: | The recycling of collector-drainage water (CDW) with high mineral content increases the salt levels in inland water bodies, which can limit the usability of the water downstream. To improve the agricultural irrigation system and livestock production in Central Asia, comprehensive quantitative and qualitative research is needed to analyze the inter-annual and multiyear CDW generation patterns. A Ph.D. research study has been designed to investigate the amount, quality, and ionic composition of CDW and its reuse potential for maize crops in the Mirzachul steppe of Uzbekistan. Reusing drainage water is an effective approach to supplementing water resources and reducing drainage disposal problems by reducing the volume of water involved. Reusing drainage water for irrigation can also mitigate water pollution issues. Different reuse methods include conventional agriculture, salt-tolerant crop cultivation, wildlife habitats and wetlands, and initial reclamation of salt-affected lands. In recent years, salinity levels in all major CDWs have shown a continuous increase. The present study is based on scientific research that involved proper fieldwork monitoring and observation while irrigating maize crops with a mixture of salt water and fresh water.
