- Association Water application and nitrogen nutrition remarkably improved the photosynthetic gas exchange parameters of wheat.
- Intervention effect Four irrigation treatments increased average stomatal conductance from 0.15 to 0.46 in 2002-2003 compared with one irrigation treatment.
- Intervention effect Four irrigation treatments increased average stomatal conductance from 0.18 to 0.33 in 2003-2004 compared with one irrigation treatment.
- Intervention effect Four irrigation treatments increased photosynthetic rate from 9.33 to 13.03 in 2002-2003 compared with one irrigation treatment.
- Association Water and nitrogen stress noticeably decreased leaf water potential, osmotic potential and relative water content of wheat.
- Association Relative water content of stressed wheat plants dropped from 98 to 75% with fewer irrigations and less nitrogen.
- Association Higher leaf water potential and relative water content were associated with higher photosynthetic rate in wheat.
- Association Water use efficiency of wheat reduced with an increasing number of irrigations.
- Association Water use efficiency of wheat increased with increasing applied nitrogen at all irrigation levels.
