| Abstract | ||
| Two pot experiments were carried out during the two successive seasons of 2019 and 2020 on pomegranate and lime seedlings at the nursery of Pomology Unit, Department of Plant Production, Desert Research Center, Egypt, to study the influence of foliar spray urea, humic acid, salicylic acid and their combinations on vegetative and root growth and leaf mineral content. All treatments were carried out at four times of both years i.e. mid- February, mid-March, mid-May and mid-July on Wonderful pomegranate and Egyptian lime seedlings. Obtained results indicated that all tested treatments significantly increased vegetative and root growth as well as leaf N, P, K, Fe, Mn and Zn content of pomegranate and lime seedlings. The combination of 5 g/L urea plus 20 g/L humic acid plus 200 ppm salicylic acid was the superior treatment in this respect, followed by the combination of 2.5 g/L urea plus 10 g/L humic acid plus 100 ppm salicylic acid to improve vegetative and root growth and leaf mineral content of pomegranate and lime seedlings. | ||
