Thirty-five-day-old seedlings were transplanted the second week of Jul. The crops received 120 kg N/ha in equal splits at transplanting, 21 d after transplanting (DT), and 42 DT. PK at 13-12.5 kg/ha were applied basally at transplanting. Soil was a loamy sand (Typic Usto chrept) with 5 mm percolation/ha, pH 8.5, ECO.15 mmho/cm. 0.23% organic C, and 0.06% total N. Results showed that root injury did not affect grain yield. However, seedling N content and uptake were significantly lower when roots were trimmed at transplanting
