| Abstract | ||||
| A pot experiment was carried out in two successive years in early summer seasons of 2020 and 2021, under protected conditions (theram house), at the Agricultural Experimental Farm, Faculty of Agriculture Menoufia University Shebin EL-Kom, Egypt. This experiment was conducted to study the effect of two sources of fertilization i.e. organic {compost (COM) and humic acid (HA)} and biological {arbuscular mycorrhizal (AM) and plant growth promotion rizobacteria (PGPB)} on mitigation salinity hazard on tomato plants (hybrid 186). Saline solutions were prepared by using NaCl to induce an EC of 3 and 6 dSm-1, in addition to tap water (0.56dSm-1) as a control. Plant growth parameters (plant height and total plant dry weight ), as well as relative water content (RWC), proline content, N, P, K , Ca, Na and Cl contents and electrolyte leakage (EL) in tomato leaves were all determined in two plant samples. Flowering date, fruit set (%), fruit weight, total fruit yield besides fruit quality (TSS and vit.C) were also estimated. Comparable to un-saline treatment (tap water i.e., 0.56 dS/m), salinity (at 3.00 and 6.00 dS/m-1) decreased tomato plant growth, fruit set (%), leaf relative water content (RWC), leaf proline content, and N, P, K and Ca contents in both young active and old inactive leaves. Tomato yield and it`s components were also diminished by salinity. On the other hand, salinity increased water use efficiency (WUE), leaf proline content, electrolyte leakage in leaves, and fruit contents of TSS and Vit.C. | ||||
