t0“Effect of nitrogen on rice yield”
e0“in a paddy light soil at Guilan province, Iran, in the year 2008 to 2009. In this experiment, four treatments including: N1, control (no N fertilizer)”
e1“Results show that total biomass (8386 kg/ha), grain yield (3662 kg/ha), plant height (127.9 cm), tillers m-2 (250.22), panicles m-2 (235.8) and total grain per panicle (103.8) reached the highest value at high nitrogen level”
