Using Potassium Sulphur as Well as Organic And Biofertilization for Alleviating The Adverse Effects of Salinity on Growth and Fruiting of Valencia Orange Trees.

摘要

During 2010/ 2011 and 2011/ 2012 seasons, the effects of single and combined applications of compost, K, S , yeast, Minia Azotene and EM1 on counteracting the adverse effects of soil and water irrigation salinity on fruiting of Valencia orange trees were investigated. Single and combined applications of Compost, potassium, sulphur, yeast, Minia Azotene and EM₁ were very effective in alleviating the adverse effects of salinity on growth and fruiting of Valencia orange trees in terms of enhancing the leaf area, all nutrients and plant pigments in the leaves, yield as well as physical and chemical characteristics of the fruits in relative to the check treatment. The promotion was associated with using K, S besides organic fertilization with yeast, Minia Azotene and EM₁. Organic fertilization with compost besides biofertilization with EM1 was essential for alleviating the inferior effects of soil and water irrigation salinity on growth and fruiting of Valencia orange trees.
