| Abstract: | The pot experiment was adopted to study the effects of topdressing stage and application methods of nitrogen on wheat yield. The results showed that spraying nitrogen at jointing stage could achieved maximum yield due to significantly increasing the plant height of wheat,spike length,spike number,grains per spike and 1 000-grain weight . |
