Abstract

Abstract An experiment was carried out in the canopy of the Department of Horticulture and Landscape Engineering / College of Agriculture / University of Karbala, Al-Hussainiya district, for the winter agricultural season 2022-2023, to study the effect of fertilizing with high-nitrogen NPK fertilizer and spraying with seaweed extract and the interaction between them on the vegetative growth characteristics of rosemary plant. The experiment included a chemical fertilizer of a type (Solucat) at 4 concentrations (0,2,4,6) gm liter 1-added to the soil and symbolized by (N) and the second factor is spraying with seaweed extract (Equilibrium) at 4 concentrations (0,1,2,3) ml Liter 1 - spraying “on the shoot, symbolized by (T) and their overlap. The experiment was carried out within the randomized complete block design (RCBD) and with three replications. The experiment included 48 experimental units in 3 plants / repeated 144 plants (anvil) starting on 1/11/2022 until 1/ 5/ 2022. The results showed that the plants were significantly superior to the level of compound fertilizer NPK (6) gm -1 in the characteristics of vegetative growth (plant height). The number of branches, stem diameter, fresh weight of leaves, chlorophyll content of leaves (46.76 cm, 23.5 branch -1 , 8.72 mm, 73.87 gm, 1.563 mg / g fresh weight) was given as the highest average, compared to the comparison treatment if given The lowest rate was (37.61 cm, 10.55 branches of a plant -1 ,6.22 mm, 54.83 gm, 1.372 mg / g fresh weight) and the concentration of (3) ml 1-algae extract was significant, as it gave the highest rate of (45.62 cm, 17.88 branches). Plant -1 , 8.02 mm, 69.24 gm, 1.607 mg / gm L -1 , compared to the comparison treatment, as it gave the lowest rate of (38.47 cm, 12.88), the branch of Plant-1, 6.14 mm, 59.72 gm, 1.284 mg L -1 , as for an overlap Among the two study workers, the highest rate was (48.44) cm, (25.3) plant branch -1 , (10.43) mm, (82.7) gm and (1.951) mg / gm fresh weight compared to the comparison treatment, which gave the lowest rate of 31.33 cm. 7.44 shoots -1 , 5.44 mm, 52.37 gm, 0.836 mg / L -1 significantly superior in all vegetative growth traits.
