The filed experiments was conducted in consecutive two seasons (2015 and 2016) at Field Crops Research Farm, Faculty of Agriculture, Mustafa Kemal University, Turkey to determine boron (B) response to the qualitative traits of maize under Mediterranean environmental condition. (ETIDOT-67 (Na2B8O13.4H(2)O)) was used as a source of boron (B) with maintain four levels of B (0, 400, 600 and 800 mg B m(-2)) at three early vegetative stage (V2, V4 and V2+V4) of maize to determine the effect on quality of corn grain. The quality characteristics of maize was significantly affected by different levels of B. Foliar application of B at growth stages of V2+V4 have been shown to be more effective for efficient B use efficiency of maize and thus improved the protein, oil and minerals. If, application of B increased the major quality traits, but decreased Cu content. At the V4 growth stage, B application was positive for all quality parameters, except minerals of B, S and Cu. The maximum value was recorded from application of 800 mg B m(-2) at V2+V4 growth stage. Therefore, application of 800 mg B m(-2) as foliar spray at early vegetative stage could be considered to achieve the good quality of maize.
