Iodine deficiency occurs when iodine levels in the soil are inadequate, resulting in limited crop uptake and, as a result, a population with insufficient iodine intake. Iodine deficiency can be avoided by biofortifying commonly consumed crops with iodine. A field experiment was conducted to investigate the effect of iodine biofortification on the nutrient uptake of fruits and plants of ‘shivam’ hybrid tomato. Potassium iodate and chitosan were applied in the form of soil, foliar, and chitosan iodate complex with control comprising 16 treatments (T1 to T16) at different stages of plant growth. Iodine accumulation in tomato fruits and plants was achieved by combining foliar and iodine chitosan forms as electrostatic interaction between chitosan and iodate prevents volatilization and gradually increases the bioavailability of iodine from soil to fruits. Biofortification of iodine throughT14- Chitosan-KIO3Complex (CsKIO3) - (SA)-10Kgha-1 + FA-KIO3-0.3% @ 60 and 90 DAT the iodine content in tomato fruit at green (0.95ppm), pink (1.01ppm) and red ripen (0.99ppm) stages of tomato and introducing it in present-day daily diet may help to reduce iodine deficiency disorder. Iodine biofortification also influenced the uptake of nitrogen, phosphorous and potassium in plants and fruits of tomatoes.
