Effect of humic acid and seaweed extract on growth, yield and fruits quality of cucumber (Cucumis sativus L)‎

Abstract EN

This experiment was carried out in Horticulture Department/College of Agriculture/ Duhok University on Cucumber plants during season 2010, to study the effect of three levels of Humic acid (0.0, 1, 2 g.L-1) and three levels of Seaweed extract (0.0, 2, 3 ml.L-1) on cucumber cv.

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
