Influence of potassium iodate and chitosan iodate complex on growth, yield, quality and iodine uptake in ‘shivam’ hybrid of tomato (Solanum lycopersicum L.)

An iodine biofortification experiment was conducted by applying potassium iodate fertilizer in soil and foliar form chitosan complex forms to investigate the growth, yield, quality uptake of shivam hybrid tomato Palaviduthi series Coimbatore region. Soil fertilization alone resulted lower fruits because is susceptible high volatilization less phytoavailability also yield poor fruits. When were applied combination through form, found be superior (carotene-1.24 mg 100gm-1 ascorbic acid- 3.56 100gm-1, titrable acidity-0.96%), with higher fruit (94.81 t ha-1) (0.99ppm). Potassium alone, either or application, increased fruits, but it did not prevent loss various pigments acids during ripening volatilization. But conserved losses reducing respiration rate oxygen permeability. Further, formed an electrostatic interaction iodate, preventing volatilisation gradually increasing bioavailability from Hence biofortifying preferred for enhancing improving content
