| Abstract | ||
| This experiment was carried out during two successive seasons 2019 and 2020 to study the beneficial effects of substituting marine algae extract concentration for mineral N, P, and K soil application on vegetative growth and its nutritional condition of 2-years old guava transplant, grown in a private orchard in Abu-Homos, El-Beheira government, Egypt. The obtained results showed that, using half of the recommended dose as a soil application for transplant with spraying algae extracts on the leaves led to an increase in vegetative growth as (length of guava transplants, No. of leaves/plant, leaf area, No. of new shoots, diameter of stem and leaf chlorophyll content). While, the control treatment recorded the highest value in leaf carotene content as compared with other treatments. Furthermore, the half of the recommended dose as a soil application for transplant with spraying algae extracts on the leaves led to an increase in leaf mineral contents (N, P, K, Ca, Mg, Fe, Zn, Mn and Cu) compared with other treatments. | ||
