Abstract:
A potculture experiment was conducted using rice as the test crop grown continuously
for two seasons to study the direct and residual effect of added Mg under rice culture in
waterlogged condition. The performance of the rice plant with respect to yield and Mg uptake was
better in karappadam soil during the first crop season; while in the second crop season, it was
higher in laterite soil. Different sources and levels of Mg applied did not have any significant
influence on yield and Mg uptake of the rice plant. There was no marked difference in total Mg
uptake between the two seasons, indicating a substantial release of Mgfrom added sources during
the second crop season also.
