| Abstract | ||
| A field study was conducted in Berjesia experiment station during winter seasons of 2008-2009 and 2009-2010 in a sandy loam texture soil classified as Typic quartizpasmment . RCBD design was used with three replications. The aim of experiment was to study the effect of different levels of amino acid application and potasium on yield properties of tomato c.v. Al- Hutoof hybrid to drought, salinity stress and then on tomato fruit productivity. The field experiment consisted of 28 treatments. The first factor was application seven levels potasium and the secondary factor was application of amino acids by spray type of amino acid mixture (Tyrosine,Proline,Arginine) with four levels (0, 100, 200 and 300 mg l-1 ). Results indicated significant effects of all amino acids with different levels in decreaseing the water and salinity stresses. The results showed that treatment with mixed sprayed amino acid in200 mg l-1 and Potasium increased yield parameters at34 %,25% in the early yield, 19%,%22 in average fruit weight; 15%, 20% in number of fruit and 38%, 47% in total yield comparing to treatment without amino acids and Potasium for two seasons respectely. | ||
