Effects of Slag-Based Fertilizer to Mitigate Salinity Stress on Greenhouse Durum Wheat (Triticum Durum Desf.) Cultivars

For a modern agricultural, the search for sustainable practices to increase productivity is fundamental. Steel slag have been studied their potential use in agriculture. These substances present great possibility of agricultural applications since they are rich nutrients, which enhance plant uptake. In this regard, effect steel based-fertilizer was investigated greenhouse durum wheat cultivation pots under salt-stress conditions. Two doses: 10 g slag/ kg soil (D1) and 20 (D2) were evaluated no (0 mM NaCl) conditions (100 salinity stress mitigation. Morpho-physiological biochemical parameters measured compared different treatments. Wheat exposure decreased its biomass, stomatal conductance, efficiency photosystem II, protein content increased total soluble sugars, hydrogen peroxide (H2O2) malondialdehyde (MDA) contents. Amended plants with (D1), led significant improve biomass an shoot root dry weights (133% 400% respectively), conductance (22 %), sugars (14 %) (158%) as control treatment 0 (C), indicating positive influence on plants. However, enrichment growth presented highest levels H2O2 MDA contents D1 after three months salt-stress. This study supports hypothesis application at lower dose mitigate stress.
