The effect of biochar at three levels (B0: no biochar; DPB: 500 g m−2 date palm biochar and PB: 500 g m−2 pistachio biochar), vermicompost at two levels (V0: no vermicompost and V1: 1500 g m−2 vermicompost) and three levels of deficit irrigation (S1: 50% water requirement; S2: 75% water requirement and S3: 100% water requirement) on the water use efficiency of eggplant. The error bars followed by a different letter are significantly different at P < 0.05 using the Duncan multiple range test
