Abstract

This study was conducted as a split-factorial in Randomized Complete Block Design with four replications in 1999-2000 in Khoram-abad. Drought treatments were the plant irrigation after soil water reached 70% (without stress), 60% (medium stress), and 50% (high stress) of FC as main plots. Zn (0, 10 and 20 kg/ha) and P (0 and 150 kg/ha P2O5) were randomly distributed in sub-plots. The results showed the whole of traits were affected by DROUGHT STRESS. By increasing in DROUGHT STRESS; seed YIELD, biological YIELD, YIELD components, HI, LAI, plant height and RWC were decreased. DROUGHT STRESS decreased seed YIELD from 10.1 ton/ha in without stress to 6.3 and 3.4 ton/ha in medium and high stress, respectively. Excess P stress above critical limit, had also similar effects on some characteristics but with lower severity than DROUGHT STRESS. No significant effects of Zn were seen. Interactions between treatments, except DROUGHT STRESS *phosphorous interaction, were not significant. When DROUGHT STRESS and excess PHOSPHOROUS occurred together, they had synergist effects on some traits.
