Abstract
Two pots experiments were carried out during summer seasons of 2011 and 2012, in order to study the effect of irrigation with sea water mixed with fresh water at different levels of NaCl (0.0, 1000, 2000 and 3000 ppm) and application of humic acid at 2cm3/l, halex-2 at 2gm /l and the combination between them as well as control (without) and their interactions on vegetative growth characters, leaf pigments, yield and its components, fruit quality and leaf chemical constituents of sweet pepper plants (Capsicum annuum L.). cv. Spanish pepper. Vegetative growth characters,i.e plant height, number of branches, leaf number, dry weight / plant, leaf area/plant, fruit yield and its components parameters and TSS in fruit juice were significantly decreased by increasing NaCl level in the irrigation water from control up to 3000 ppm while, irrigation with 2000 ppm gave the highest values of K percentage on fruit. On the other hand, 3000 ppm NaCl resulted in the highest values of titratable acidity and proline contents in the leaves. Treating sweet pepper plants with the combination between halex-2 at 2 gm/ l and humic acid at 2cm3 / l recorded the highest values of all studied growth characters, average fruit weight, early yield, total yield TSS and nitrogen percentage followed by humic acid at 2cm3 / l with non significant differences between both treatments while, treating plants with halex-2 at 2gm/l recorded the highest values of phosphorus percentage. Zero Nacl in combination with humic acid at 2cm3 / l singly or with halex-2 at 2 gm/ l caused a stimulatory effect on most of the studied characters of sweet pepper plants. Meanwhile, the same treatments recorded the lowest values of TSS in pepper. On the other side, the interaction between NaCl at a rate of 3000 ppm in the irrigation water without adding halex-2 or humic acid (control) recorded the lowest values of all studied growth characters, yield and its components and fruit quality.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
