Abstract

Iron supplementation of paddy varieties had been carried out by the economical agronomical biofortification process. Impressive changes had been observed among varieties for yield and yield related traits along with increased iron contents in dehusked rice varieties. The increase in grain yield per plant was higher in HBC19, Pusa 1121 while lowest in Govind. Palman 579 showed maximum increase while Super had minimum increase of in thousands grain weight at higher augmentation level. Increase in numbers of seeds per panicle was also observed in all rice varieties while maximum by Pusa1121followed by Super. Fe content in roots and shoots increased with increase in Fe concentration. Roots of HBC19 and Palman579 and shoots of Pusa1121 contained higher iron. Highest iron in dehusked grains was recorded in Palman579 followed by HBC19, Pusa1121, HKR120, Super and Govind. Agro biofortification desired a balance of iron augmentation as its excess causes toxic affect on the physiological process
