| Abstract | ||
| A filed experiment was carried out to study the effect of addition pressmud (PM) as organic wastesunder saline irrigation water on some soilproperties, Tuta Absuluta Damage and plant growth. PM was applied at rates of 0, 5 and 10 ton/fed. The soil was cultivated with tomato (Genotype: Alissa) under salinity irrigation whichapplied having 0, 25 and 50 mM NaCl.Untreated soil was used as a control (CTRL). At the end of the experiment, soil samples and plants were taken from each treatment. The results showed that the application of PM significantly decreased the soil bulk density, soil pH, while, under saline irrigation water increased them compared with PM. On the other hand, PM increased each of ECe, cations such as Ca+2 + Mg+2, Na+ and K+ while these parameters were increased with increasing salinity levels compared with CTRL. In addition, data showed also that the parametersplant growth were significantly positively affected by the application of PM addition rates compared with control or salinity stress. Na+ was accumulated into plant tissues with increasing level NaCl. The Ca2++ Mg2+ and K+ contents reduced under saline irrigation water compared as control or PM addition rates. On the other hand, plants growing under 10 ton/fed of PM and freshwater had lower number of miners/leaf and infested fruits/plant compared with plants growing under 5 ton/fed of PM or control treatment. High level of salinity had a good effect on T. absluta damage than control treatment. These results support the hypothesis that plants growing under a good level of organic fertilizer and salt-stress are better defended againstT. absluta. | ||
