Soil-water interactions and its management is serious issue in water availability for plant cultivation especially in the water scarce area. The objective of this study is to determine water use efficiency of maize which is cultivated in vertisol soil with different water content and biochar application. The experiment was designed in four level water content of field capacity (FC) vis., 100%, 90%, 80%, 70%., and three treatments of soil amendment (control, biochar, and zeolith addition). Data was collected in terms of water content dynamics (water use efficiency, crop water consumption), and dry matter weight. Results found that biochar application had significant effect in all parameters evaluated compare to control and zeolith. In combination treatments, there is no significant effect of soil amendment and control with 70% and 80% FC treatments to plant dry weight. Various value was also observed in crop water consumption with significant effect in soil amendment on 100% and 70% FC, conversely there is no different effect in 80% and 90% FC. Water use efficiency was affected by soil amendment but it shown differences in treatment of water content level. All results of this study therefore concluded that soil amendment and water content management need to be combine in support plant growth on the area with water limiting factor.
