Simultaneous Effect of Deficit Irrigation and Salinity on Yield and Yield Components of Tomato under Field Conditions
Salt and drought stress is one of the main problems of Agricultural production in many parts of<br />the world, especially in arid and semi-arid area. Therefore, this study was conducted to investigate<br />the effect of both stresses (individually and simultaneously) on yield and yield...

| description | Salt and drought stress is one of the main problems of Agricultural production in many parts of<br />the world, especially in arid and semi-arid area. Therefore, this study was conducted to investigate<br />the effect of both stresses (individually and simultaneously) on yield and yield component of tomato<br />(Super Strain B) in order to program irrigation management in Karaj. The experiment was carried out<br />as Factorial on base of complete randomized design with three replicates including two factors:<br />Salinity and irrigation water. Salinity and irrigation water factors consisted of four levels (S1=0.7,<br />S2=4, S3=8 and S4=12 dS/m) and three levels (W1=100, W2=75 and W3=50 percent of water<br />requirement), respectively. The soil texture was sandy loam. The results of this study showed that the<br />yield production reduced by increasing salinity and drought stresses. The maximum yield (240.7 g)<br />was corresponded to W1S1 treatment and the minimum yield (48.58 g) was corresponded to W3S4<br />treatment. Salinity, deficit irrigation and their interaction had significant effect (p<0.01) on dry<br />weight, root length and tomato evapotranspiration, but they did not have any significant effect on the<br />number of fruits. The combined impact of salinity and deficit irrigation did not have any significant<br />effect on plant height and dry weigh. |
