The impact of nitrogen (N) and boron (B) foliar applications on Solanum melongena growth, yield, and phytochemicals was studied. The impact of foliar applications using N levels (0, 0.25%, 0.5%, and 1%) and B levels (0, 0.1%, 0.25%, and 0.5%) following a randomized block design with three replications was studied. With the increase in N level, the yield characters increased. Foliar application of N shows the maximum height of plant (112.5 cm), number of leaves (186.0), leaf area (46.20), number of branches (7.67), number of blossom fowers/plant (21.25), number of fruits/plant (11.42), fruit length (10.97 cm), fruit width (7.39 cm), fruit volume (305.7), fruit weight (12.67 g), fruit yield (12.78), protein (10.9%), total carbohydrates (27.5%), and crude fber (7.21%) while decreasing minimum days at 50% appearance of fowers (48.0). In the case of B application, the maximum height of the plant (112.0 cm), number of leaves (187.6), leaf area (47.82), number of branches (7.67), number of blossom fowers/plant (22.08), number of fruits/plant (11.33), fruit length (10.95 cm), fruit width (7.35 cm), fruit volume (298.0), fruit weight (206.1 g), fruit yield (12.13), protein (9.31%), carbohydrates (30.2%), TSS (4.20), crude fber (7.34%), DPPH (4.68 mg/mL), Chl a (1.39), Chl b (0.53), TPC (60.78), DAO activity (81.43), and PAO activity (39.10) were observed, while decreasing minimum days at 50% appearance of fowers (48.33). Application of N at 0.5% and B at 0.25% increased the growth, yield parameters, and phytochemical contents of S. melongena. The impact of diferent nitrogen and boron foliar applications on eggplant growth, phytochemicals, and quality attributes is signifcantly improved.
