This experiment was carried out to know the effects of fertilizer application methods of the growth and physiological characters of rice seedling. For this purpose, three levels of phosphorous fertilizer(0, 6 and 12g/seed box) and three methods of nitrogen application(heavy- N-basal, split and heavy-N-top dressing) at seed box, seed bed and different rice growing stages were treated. The results obtained were as follows ; 1. The plot which received heavy-N-basal application with fused phosphate caused physiological disorder like a dampingoff of rice seedlings severely. 2. The rooting ability of rice seedling after transplanting in creased significantly by the phosphorous application compared to no treated plot. 3. The occurrence of physiological disorder like a dampping off was shown severely in plot which had a heavy-N-basal and split application. However, the plot which did not applied phosphorous didn’t show any physiological disorder. 4. The chilling injury of rice seedlings was appeared from the, plots that had heavy-N-basal and split plots regardless of phosphorous levels. 5. Heavy-N-basal and split application accelerated leaf length and width elongation during the early growing stage it has the risk of overgrowing that leads to dead leaves. 6. The plot receiving heavy-N-top dressing increased number of green leaf at the time of transplanting and raised uniformality of seedlings, hence, resulted in healthy seedlings(Dry weight of shoots over plant height rate increased), compared to other treatments. 7. The rate of leaf development dry matter production and rooting ability were enhanced when the leaf of overgrowing seedlings were cutted at the 2 and 3 leaf stage.
