Kusahonami) during two rice-growing seasons Abstract This paper focuses on N balance in a paddy field planted with whole crop rice (Oryza sativa cv. Kusahonami). The experiment was conducted with two treatments during two rice-growing seasons: one was fertilized with N (160 kg N ha −1 ; 16N plot) and the other unfertilized (0N plot); both plots were fertilized with P and K. The N input from precipitation was 15 and 12 kg N ha −1 in 2002 and 2003, respectively. The N input from irrigation water reached as much as 123 and 69 kg N ha −1 in 2002 and 2003, respectively. This was because irrigation water contained higher NO 3 − concentrations ranging from 4 to 8 mg N l −1 . The N uptake by rice plants was the major output: 118 and 240 kg N ha −1 in the 0N and 16N plots in 2002 and 103 and 238 kg N ha −1 in 2003, respectively. N losses by leaching were 4.8-5.3 and 6.5-7.3 kg N ha −1 in 2002 and in 2003, respectively.
