Biofortification of Diverse Basmati Rice Cultivars with Iodine, Selenium, and Zinc by Individual and Cocktail Spray of Micronutrients

Given that an effective combined foliar application of iodine (I), selenium (Se), and zinc (Zn) would be farmer friendly, compared to a separate spray each micronutrient, for the simultaneous biofortification grain crops, we effectiveness foliar-applied potassium iodate (KIO3, 0.05%), sodium selenate (Na2SeO4, 0.0024%), sulfate (ZnSO4∙7H2O, 0.5%), separately in their combination (as cocktail) micronutrient four Basmati cultivars rice (Oryza sativa L.). Foliar-applied, or cocktail did not affect yield, but yield varied significantly among cultivars. Irrespective treatments, brown cv. Super Kisan had substantially higher concentration micronutrients than Basmati-515 Chenab Basmati. With KIO3, alone cocktail, I increased from 12 186 µg kg−1. The average with KIO3 was 126 μg kg−1 Basmati-515, 160 Basmati, 153 306 Selenium 54 760 kg−1, Na2SeO4 individually respectively. inherent Zn ranged between 14 19 mg by 5–6 per kg grains ZnSO4∙7H2O cocktail. results also showed existence genotypic variation response demonstrated I, Se, could strategy these address hidden hunger problem human populations.
