Suitable rice varieties for iron toxic soils of Orissa

Iron toxic soil, one of the handicapped soils of Orissa produces poor rice yield. Normal rice production in these soils by means of amelioration is costly. Considering rice genotypes to be a better option for getting expected yields, 65 genotypes were evaluated for their tolerance capacity to iron toxicity in a typical iron toxic soil of Bhubaneswar, Orissa Rice genotypes irrespective of their duration showing score value between 1 to 2 produced normal yields and those having score between 7 to 9 yielded the minimum. Genotypes Kalinga- III, Udayagiri, Konark and Panidhan under extra early, early, medium and late durations, respectively produced significantly higher yields at different score scales than their respective duration groups.
