| Abstract | ||
| This study was conducted in one of the greenhouses belonging to the research station of the Department of Horticulture and Landscaping - College of Agriculture , Tikrit University in the period extending from (15/10/2022) until (30/5/2023) , to find out the effect of adding several combinations of organic fertilizers 0 comparison treatment, 42 cm3 of tea residue + 42 cm3 of poultry manure + 42 cm3 of sheep manure, 63 cm3 of poultry manure + 63 cm3 of tea residue, 63 cm3 of sheep manure + 63 cm3 of tea residue and spraying with seaweed extract in three concentrations 0 Comparison treatment, 0.5 g L-1, 1 g L-1 ) and the interaction between them in the growth and active component of ornamental pepper plant, the results showed that the treatment (42 cm3 of tea residue + 42 cm3 of poultry manure + 42 cm3 of sheep manure) excelled in most vegetative growth traits of ornamental pepper plants (plant length, number of branches, and fruit content of gallic acid, caffeic acid, and the alkaloid capsaicin) compared with the comparison treatment, and the treatment (63 cm3 poultry manure + 63 cm3 tea residue) was significantly superior in leaf area characteristic, while the treatment of spraying Seaweed extract did not record a significant superiority in the vegetative growth traits, and the concentration 1 g L-1 of the Seaweed extract was significantly superior by giving the highest values for the fruits’ content of gallic acid, caffeic acid, and the alkaloid compound capsaicin. The interaction treatment between the combination of organic fertilizers (63 cm3 of tea residue + 63 cm3 of poultry manure) in addition to spraying with extract of seaweed at a concentration of 1 g L-1, it excelled in the characteristics of vegetative growth of the plant (number of branches, plant length). | ||
