A field experiment was conducted at the Horticultural Research Farm, College of Horticulture, Anand Agricultural University, Anand during 2024 to evaluate the effect of multi-micronutrients on the quality of sweet orange (Citrus sinensis L. Osbeck) cv. Phule Mosambi. The experiment, laid out in a Completely Randomized Design with nine treatments, involved different combinations of government-notified micronutrient grades from Gujarat (G-IV and G-V) and Maharashtra (G-II-MH), applied through soil and foliar methods. Among the treatments, foliar application of G-IV (Fe-4.0%, Zn-6.0%, Cu-0.5%, B-0.5%, Mn-1.0%) + Mo-0.1% combined with soil application of G-V (Fe-2.0%, Zn-5.0%, Cu-0.2%, B-0.5%, Mn-0.5%) under T₉ significantly enhanced fruit quality, recording the highest total soluble solids (9.22 °Brix), total sugars (7.03%), juice content (52.12%), sugar:acid ratio (20.64) and ascorbic acid (44.15 mg/100 ml), along with the lowest acidity (0.45%) and minimum rind thickness (4.07 mm). The control treatment T₁ consistently recorded the lowest values for all parameters.
