Abstract

The effect of DROUGHT STRESS on nitrogen and SPAD READING of WHEAT (cv Falat) was studied in a complete randomized block design with 3 replications; in the green house. Five levels of DROUGHT STRESS (-0.3, -1, -3, -5 and -7 b) were used as treatments. Soil water curves were plotted using presser plate at a wide range of soil water potential. Water requirement for each treatment determined with weighing by day of each treatment. SPAD READING, nitrogen content, STOMATAL RESISTANCE and specific leaf weight (SLW) of flag leaf and two leaves under flag leaf were measured at anthesis stage. Results showed that with increasing DROUGHT STRESS SPAD READING, nitrogen content, STOMATAL RESISTANCE and SLW increased and there was a high relationship between DROUGHT STRESS and SPAD READING. It was concluded that SPAD READING is a good index of nonstomatal resistance for preduction water stress severity.
