Abstract:
Afield experiment was conducted in the village of Giebul in the countryside of Jableh during the agricultural season 2021/2022, to study the effect of adding (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 Productivity traits of Eruca sativa “local” 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 L.S.D at the level of significance of 5%. The results showed that there was a significant effect of urea fertilization in all studied traits. The average 200 kg/ha nitrogen achieved the highest seed production with an average of (213.50 g/m2), the highest number of seeds/plant (1006.50 seeds), and the highest biological yield (525.00 g/m2). And the highest weight of 100 air-dried fruits was (9.84 g). The results also showed a significant effect of potassium sulfate fertilization in all studied traits, as the rate of 100 kg/ha achieved the highest seed yield with an average of (155.48 g/m2), the highest number of seeds/plant (1925.33 seeds), and the highest biological yield (420.00 g/m2) and the highest weight of 100 air-dried fruits (8.43 g). The interaction between urea fertilization and potassium sulfate had a significant effect on all studied traits, as the interaction 200 kg/ha urea and 100 kg/ha potassium sulfate achieved the largest rates in all studied traits.
Key words: Rocket, Fertilization, Urea, Potassium, Productivity.
