The results shows that spraying Humic acid or Seaweed extract led to positive significant difference in leaf area, leaves chlorophyll content, plant length, fruits number, early and total yield as well as fruit weight, fruit length, yield per plant, fruit dry weight, fruit chlorophyll content and TSS as compared to untreated plants.

The interaction between Humic acid and Seaweed extract was significantly enhanced all detected traits, Since cucumber plants received 2 g.L-1 Humic acid and sprayed with 3 ml.L-1 of Seaweed extract were characterized by the highest values of all growth and yield characteristics
