BACKGROUND: Innovations for saving water in irrigated agriculture and thereby im-proving water use efficiency are of paramount importance in water-scarce regions. Conven-tional deficit irrigation is one approach that can reduce water use without causing signifi-cant yield reduction. OBJECTIVES: The purpose of this study was to evaluate the effects of different irriga-tion regimes and Potassium nano chelate on effective traits on Corn crop production under the Mediterranean climatic conditions in Southwest of Iran. METHODS: Current research was done according split plot experiment based on com-pletely randomized block design at 2022. So the water deficit at three level [60 (control), 90 and 120 mm evaporation from class A evaporation pan] in main plots, and potassium nano chelate at three levels [0 (control), 2 and 4 kg.ha-1) in sub plots. RESULT: Significant difference in growth parameters was observed between water defi-cit and commercial fertilizer (potassium) treatments. Potassium chelate recorded higher yields relative to water deficit with similar 2 and 4 kg.ha-1 rates, though statistically signifi-cant. Yield deficiency was observed in maize at controlled potassium application. Yield components, showed both K and water deficiencies in 7th week, while control treatments showed K deficiency in 14th week by potassium chelate at low application rates. CONCLUSION: The agronomic optimal rate of potassium Chelate determined by evaporation pan function were found to be higher than that of 90 mm evaporation that was found to enhance growth and yields of crops potentially have greater benefits such as improving soil health and plant resilience.
