| Abstract |
Two field experiments were carried out at Shandaweel Agricultural Research Station ( South Nile Vally), ARC, Egypt, during 2002 and 2003 seasons to study the effect of water stress [ i.e. irrigation after the depletion of 25-30% from available soil moisture(I1), irrigation after the depletion of 45-50% from available soil moisture (I2), and irrigation after the depletion of 65-70% from available soil moisture (I3),] on four sesame varieties [ i.e. Giza, 32 (V1), Toshky, 1 (V2), Shandaweel, 3 (V3), and Sohag, 3 (V4), ] . The effects of the previously mentioned factors on water relations, yield, yield components and crop tolerant for wilt disease were studied.
Results indicated that average values of water consumptive use irrespective to irrigation treatments and varieties together were 2226 and 2112 m3/fed in 2002 and 2003 seasons respectively. Results indicated that increasing irrigation intervals ( irrigation after the depletion of 65-70% from available soil moisture) reduced actual evapotranspiration by 36.2% as compared with irrigation after the depletion of 25-30%.
Highest average WUE values of 0.36 and 0.35 Kg seed/m3 water consumed resulted from I3V2 and I3V3, which can be recommended as best treatments of sesame for cultivating under similar condition at Shandaweel. Results indicated also that the most efficient method for calculating sesame water consumptive in Upper Egypt is Doorenbos-Pruitt formula.
Significant interaction effects were found between irrigation treatments and sesame varieties for number of capsules/plant, seed weight/plant and seed yield/plant. The best interaction effect on all characters was obtained from the treatments of I2 and I3 with the variety of V2 and V3 Results indicated also that maximum values of oil yield wee obtained from the treatment of I2.
The interaction effects were found between irrigation treatments I2 and I3 and sesame varieties V2 and V3 respectively.
Wilt diseases percentage increased with increasing soil moisture content. The maximum values were obtained from I1 (irrigation after depletion 25-30% from available soil moisture) . Results cleared that the variety V4 was the more tolerant wilt diseases compared with the other varieties under study
