GROWTH OF RICE (ORYZA SATIVA L.) AS INFLUENCED BY DIFFERENT WATER REGIMES | BIONATURE

Rice (Oryza saliva L.) types "Kranti" and "Kalimunch" were tested for their growth performance under various water regimes. The height of the plant, the number of tillers per plant, the number of leaves per plant, the root length, the fresh weight of aerial plant parts and root parts, and the dry weight of the root all dropped one day after the ponded water was drained.

One day after the flooded water was drained, the chlorophyll content in leaves of "Kranti" plants that were given water dropped. In all kinds, plant survival is significantly reduced when water supply is limited. The available nitrogen content in soil is higher in plots with limited water availability than in plots with plants that are continuously immersed. This could be related to lower nitrogen uptake in plants grown on plots with inadequate water supply. This, however, necessitates more evidence.
