The present investigation entitled “Studies on the effect of foliar application of micronutrients and their schedule of spray on quality of beetroot (Beta vulgaris L.) cv. Crimson Globe under Telangana conditions’’ was carried out during the rabi season of the year 2021-22 at the College of Horticulture, Rajendranagar, Hyderabad.

The field experiment was laid out in factorial randomized block design with three (3) replications and fourteen (14) treatment combinations. Seven (7) micronutrient concentrations are M₁: Zinc, Iron, Manganese each at 150 ppm, M₂: Zinc, Iron, Manganese each at 250 ppm, M₃: Zinc, Iron, Manganese each at 150 ppm + Copper at 100 ppm, M₄: Zinc, Iron, Manganese each at 250 ppm + Copper at 200 ppm, M₅: Zinc, Iron, Manganese each at 150 ppm + Copper at 100 ppm + Boron at 200 ppm, M₆: Zinc, Iron, Manganese each at 250 ppm + Copper at 200 ppm + Boron at 400 ppm, M₇: Control (No micronutrients spray) and two (2) schedule of sprays at 25 DAS and 35 DAS were tried. The results pertaining to quality parameters indicated that among the all treatment combination, foliar spraying of M6 (Zinc, Iron, Manganese each at 250 ppm + Copper at 200 ppm + Boron at 400 ppm) at 35 days after sowing registered significantly highest total soluble solids (9.78 oBrix) reducing sugars (1.92 %), total sugars (7.50 %) and ascorbic acid content (4.62 mg 100g^-1). Where as titratable acidity and root rotting were found to be non-significant.
