Cu concentration in the rice plants decreased gradually toward maturity and reached minimum level in the straw. Cu content of plants and of grains at 80 d were similar. Applying 20 and 40 kg Cu affected Cu content similarly, indicating that the 20 kg application was sufficient for these cropping conditions. Maximum Cu uptake was with 40 kg Cu/ha.
