Partial submergence and field capacity interactions in transplanted rice

C. Y. Tay and S. Abdul Wahab

Abstract

The study showed that field capacity reduced culm height with concomittent increase in the number of lighter, fewer spikelet-bearing panicles in the hill. Partial submergence increased culm height with lesser number of heavier. more spikelet-bearing panicles. When the duration of occurrence of these environments increased. the magnitude of their effects on the rice crop also increased. However. when these environments occur in succession. The effects of the proceeding environment could not be negated by those of the succeeding environment. This was particularly distinct when the duration of the proceeding environment was longer than the succeeding environment. Varietal interactions with the sequence of environment occurrence were complex. MR ,13 is a tolerant variety suitable for such environments.
