In direct-sowing rice culture using cloth mulch, puddling and leveling (P & L) is usually done 2 days before the mulching (sowing). However, very difficult, due to muddy condition of soil. Comparative studies were made observe effects timing P L, that is, L 10 (P10) vs. (P2), on operator's physical stress, growth, grain yield. Basal fertilizer was applied in P2 treatment (P2-B2), topdressing at 29 heading all treatments. For P10 treatment, basal fertilization set 14 (P10-B14) or 3 (P10-B3) mulching.Results revealed had no significant effect growth yield between P10-B14 P10-B3 The stress low higher soil hardness ; however 12% lower than P2-B2 percentage ripened grain. Because inorganic nitrogen soil, leaf area suppressed dry matter production which resulted To increase future research needed consider application amount topdressing, also reduce gap time mulching.
