%X The field studies indicated that in dry years,both irrigation and nitrogen application had a marked yield increment effect,but irrigation played a more important role.Irrigation at jointing and booting stages could induce a higher grain yield,but irrigation at jointing,booting and grain-filling stages had a less yield increment effect if nitrogen was applied as base fertilizer.Insufficient irrigation reduced the nitrogen efficiency and yield,which could be compensated to some extent by increasing the nitrogen application rate.Only a suitable combination of irrigation and nitrogen application could effectively coordinate the relationship between yield components and increase grain yield.
