Abstract:
A field experiment was conducted in the village of Jiebol in the countryside of Jableh city during the agricultural season 2021/2022, to study the effect of adding nitrogen fertilizer (urea 46%) at a rate of 0, 100 and 200 kg/ha, and potassium sulfate fertilizer at a rate of 0 and 100 kg/ha and the interaction between them in some Growth characteristics of Eruca sativa Mill.plant, the experiment was designed as a factorial experiment carried out in a randomized complete block design with three replications, and the comparison between the means was done using the least significant difference test LSD at the level of significance of 5%. The results showed a significant effect of nitrogen fertilization on all studied characteristics, and the average 200 kg/ha achieved the highest plant height (83.00 cm), highest number of branches on the plant(6), highest number of leaves on the plant(21.50), highest leaf area(64.85 cm2), highest wet weight(68.00 g) and dry weight(10.50 g). The results also showed a significant effect of potassium sulfate fertilization in most of the studied characteristics, adding 100 kg/ha led to a significant increase in plant height (78.66 cm), number of leaves on the plant (15.66),wet weight(52.05 g) and dry weight of the plant(8.40 g). The interaction between nitrogen and potassium fertilization had a significant effect on all studied characteristics, as the interaction 200 kg/ha urea and 100 kg/ha potassium sulfate achieved the largest rates in all studied characteristics.
Key words: Rocket, Fertilization, Nitrogen, Potassium, Growth.
