Abstract— A study was conducted to evaluate rice germplasm for their arsenic content in different plant parts and phosphorus content in grains. Results showed that in the rice plant highest arsenic was accumulated in the roots and the lowest in the grain. The arsenic accumulation follows the order of root>shoot> leaf> grain. The results also revealed that IRRI dhan was quite tolerant to arsenic and Satabdi 1 was susceptible to arsenic accumulation during kharif season, whereas during boro season IET-4094 accumulated more arsenic in grain and IR-50 accumulated less arsenic in grain. Results also showed that kharif rice genotypes bore strong positive association between total phosphorus percent with arsenic content in grain, whereas strong negative association was found in boro season rice genotypes.
Keywords— Arsenic, Rice (oryza sativa L.), phosphorus, West bengal.
