Abstract
The study was conducted during 2022/2023 in the fields of the College of Agriculture, Hawija, University of Kirkuk, to study the effect of salicylic acid (0, 25, and 30 mg L-1), planting spacing (0.15, 0.2, 0.3 m) and interaction on caraway. Randomized complete block design with three replications was applied. The distance of 0.2 m gave the highest plant height (85.27 cm), number of branches (10.3 branch/plant), number of inflorescences in main flower reached 95.10 inflorescences/flower, and wet and dry (280.3 and 38.13 grams/plant), respectively. The 50 mg L-1 gave the highest plant height (64.86 cm), number of branches, (4.22 branch/plant), and the wet and dry weight and weight of a thousand seeds (278.6, 35.46, and 6.72), respectively. The interaction between planting spacing 15 cm and 50 mg L-1 led to an increase gave the highest plant height (73.18 cm) and number of flowers per plant (15.92 flower/ plant) and increased the rest of the characteristics. The interaction between 0.3 m and 50 mg L-1 was superior in the number of flowers per plant (17.66). The interaction between 0.3 m and 25 and 50 mg L-1 was superior in wet and dry weight (198.70 and 201.77 g/plant), respectively. As for the interaction between 50 mg L-1 and 0.2 m gave the highest value of 1000 seeds (6.36 g).
