Summary

Manganese absorption by rice plants under flooded and unflooded conditions, in an upland and a lowland soil was studied. Both under flooded and unflooded conditions the rate of manganese absorption was high during 3rd to 4th week and again during 9th to 10th week.

Rice grown under flooded conditions, in lowland soil absorbed more manganese and showed higher dry matter accumulation than under unflooded conditions. However manganese absorption and dry matter accumulation in rice grown under flooded conditions in upland soil were lower than under unflooded conditions.

Rice grown under flooded conditions may give lower yields than rice grown under unflooded conditions due to some factor or combination of factors one of which may possibly be a high soluble iron content which interferes with the absorption of manganese.
