A pot experiment was carried out to evaluate the influence of foliar application of boron, copper and their combinations on the quality of tomato. The treatments were arranged in a Complete Randomized Design (CRD) with eight (8) replicates. There were ten (10) treatments viz., (T1) H3BO3=150 ppm; (T2) H3BO3 = 250 ppm; (T3) H3BO3 = 350 ppm; (T4) CuSO4 = 150 ppm; (T5) CuSO4 = 250 ppm; (T6) CuSO4 = 350 ppm; (T7) H3BO3 (150 ppm) + CuSO4 (150 ppm); (T8) H3BO3 (250 ppm) + CuSO4 (250 ppm); (T9) H3BO3 (350 ppm) + CuSO4 (350 ppm); (T10) Control (Boron was applied as H3BO3 and copper is applied as CuSO4). The results showed that foliar application of boron, copper, and their combinations significantly influenced yield and quality parameters such as acidity, ascorbic acid, TSS and pH. The effect of B is greater than that of Cu. The application of B increased the fresh weight of fruits (H3BO3 - 350 ppm), pulp weight (H3BO3 - 150 ppm) and TSS (H3BO3 - 150 ppm). The combined application of B and Cu improved acidity (H3BO3 - 250 ppm + CuSO4 - 250 ppm) and pH (H3BO3 -150 ppm + CuSO4 - 150ppm). However, foliar application of Cu alone significantly enhanced ascorbic acid (CuSO4 - 350 ppm) and TSS (CuSO4 - 250 ppm). It is apparent that B concentration at different levels had significant positive effect on most of the quality parameters tested.
