Response of Celery to addition of nitrogen and
spray with salicylic acid in the leaves content of
nutrients

Abstract
To study the response of the celery plant to nitrogen fertilization and spray with salicylic acid in the leaves content of
nutrients, the research was conducted in one of the fields of the Department of Horticulture and Gardening Engineering /
College of Agriculture / University of Baghdad within the 2019-2018 season. The research was carried out as a global
experiment and with the design of complete randomized sectors (RCBD) and with three replicates, the first factor included
the addition of nitrogen with three levels and its symbol (N) (N1 control) , (N2) g / m 2 18 ) , (N3) 37 g / m 2 and the second
factor spraying acid salicylic is denoted by (S) , (S1 control ) , (S2 25 mg / L ) , (S3 50 mg / L ) , (S4) 75 mg / L ) and the
interference between them. The results showed that the treatment of interference between nitrogen fertilizer and spray with
salicylic acid (N3S4) in The percentage of N, P and K elements in the leaves was 1.80, 0.0080 and 2.91%, and the element
Mg , Fe and Ca were 4376.3, 3111,and 6669 mg.kg – 1 dry matter, respectively
