    The deficiency of nitrogen (N) and boron (B) is increasing among the cereal crops that reduces yield and nutritional value of grains. Foliar spray is a possible option to maximize uptake of nutrients which enhances the productivity of wheat. A field experiment was conducted to determine the effect of foliar application of nitrogen and boron on growth, yield and quality of wheat at Agronomic Research Farm, University of Agriculture, Faisalabad during Rabi season 2017-18. Crop was sown by hand drill in plots with net size 5.0 m × 1.8 m. The experiment was consisted of 16 treatments in RCBD factorial design with two factors which was replicated three times. Factor A consisted of four levels of nitrogen (N0 control = 0%, N1 = 4%, N2= 8% and N3 = 12%) and Factor B consisted of four levels of boron (B0 control = 0%, B1 = 1%, B2 = 2% and B3 = 3%). The sources for nitrogen and boron were urea and boric acid which contains 46% nitrogen and 17% boron, respectively. Significantly the maximum spike length (17.15 cm), grains spike-1 (57.41), 1000 grain weight (36.15 g), grain yield (5.47 t ha-1), biological yield (14.42 t ha-1), harvest index (37.98m%), proteins (12.90 %) and carbohydrates (69.02 %) were noticed when 8 % foliar spray of nitrogen at tillering stage and 2 % boron at booting stage was applied. It is recommended from observations that 8 % foliar spray of nitrogen at tillering stage and 2 % boron at booting stage is helpful for achieving higher economic yield of wheat. It was concluded from the research that application of nitrogen and boron at a certain level can effectively enhance crop productivity as well as economic returns. © 2019, Elite Scientific Publications.
