Effect of arsenic (As), As + Azadirachta indica extract (Ai) and As + Ocimum sanctum (Os) extract treatments in the growth medium on a length, b fresh weight and c relative water content of roots and shoots of rice seedlings at 4 and 8 days of treatment. Seedlings were grown in hydroponics for 8 days under control, control + A. indica extract (control + Ai), control + O. sanctum (control + Os), 50 µM As (As) and 50 µM As + A. indica extract (As + Ai) and 50 µM As + O. sanctum extract (As + Os). Values are mean ± SD based on three independent determinations and bars indicate standard deviations. The typical mean with the highest absolute value and other means not statistically different from the highest value have been represented as letter ‘a’ and lesser mean values progressively have been represented as letters ‘b’ and ‘c’
