The study was conducted in Al-Najaf Agriculture Directorate during the spring season of 2021. The experiment tested four fertilizer treatments including control treatment, 4 g.L-1 of seaweed extract (Seaweed Energe), 15 g.plant-1 of bio-fertilizers (Azotobacer chroococcum), and a combination of organic and biological fertilizers on three varieties of chili pepper including Local, Barbarian, and Anaheim. Randomized Complete Block Design (R.C.B.D) was used modeling Split-Plot system with three replications. Duncan Multiples Range Test was adopted to compare the means at the probability level of 0.05.
The results showed the superiority of the Barbarian variety in parameters of plant height and leaf area while the local variety recorded the highest value of the leaves number per plant and the dry matter of the vegetative system. Anaheim variety was superior in the leaves content of total chlorophyll. As for the nitrogen and phosphorous percentage, differences between the varieties were not noted. The application of liquid organic fertilizer plus bio-fertilizer showed significant superiority in all tested indicators.
