| A field study was conducted in Berjesia experiment station during the winter season of years 2009-2010 in a loamy sand texture soil classified as Typic quartizpasmment . Split-split plot with RCBD design was used. The aim of experiment was to study the effect of different methods of application and rates of some amino acid on the abiliity tomato plant c.v. Al- Hutoof hybrid Lycopersicn esculentum mill to withstand salinity stress and then on tomato fruit productivity. The field experiment consisted of 30 treatments :the main factor was method of application of amino acids by spray or with irrigation water ; the secondary factor was the type of amino acid (Tyrosine , Proline , Arginine) and their combination mixture and three levels of amino acid (0 100 ، 200 ، mg l-1 ). Results indicated the significant effect of all amino acids with different level decreased the stress effects of salinity and drought .The best result for all parameters growth of tomato plant when three amino acids were mixed and sprayed in200 mg l-1 comparing with control treatment . | ||
