Remarks: 1: the number of grains per panicle (grains), 2: percentage of grain pithy (%), 3: grain weight of 100 grains (g). N0: without submergence, all N fertilizer was given during planting; N1: with submergence during 7–14 days after planting, N fertilizer was given during planting; N2: with submergence during 7–14 days after planting, 1/2 dose of N fertilizer was given during planting and the rest was given at 42 days after planting; N3: with submergence during 7–14 and 28–35 days after planting, all N fertilizer dose was given during planting; N4: with submergence during 7–14 and 28–35 days after planting, 1/2 dose of N fertilizer was given during planting and the rest was given at 42 days after planting. |
