Chemical Composition of Salix babylonica Seedling

Abstract: A pot experimint was carried out at the Nursery of Forestry Department, Horticulture Research Institute, Agriculture Research Center, Giza, Egypt, in the two successive seasons, 2018/2019 and 2019/2020 to study the effect of three nitrogen fertilizer forms (Ammonium sulfate, ammonium nitrate and calcium nitrate) under different levels of salinity on growth and chemical composition of Salix babylonica seedling grown in sandy loamy soils. The results showed that, increasing salt concentration decreased seedling height, stem diameter, shoots and roots fresh and dry weights, number of branches and number of leaves concern with 9dSm concentration with any nitrogen form, when compared to control. On the other hand, sugars, proline, 1 Na and Cl increased by increasing salinity level, while chlorophyll, N, P, K and Ca were diminished. The results disclosed that using calcium nitrate as a form of nitrogen significantly increased whole of the studied growth characters compared to other sources of N fertilizers. Also, using calcium nitrate increased the contents of N, P, K and Ca, as well as chlorophyll, sugars and proline and decreased the contents of Cl and Na compared to ammonium sulfate and ammonium nitrate under the same level of salt concentration
