| Abstract | ||||
| Phaseolus vulgaris L. are salt-sensitive plants in all growth phases. Hence, this study aimed to investigate the benefit impacts of magnetized water (MW) alone or combined with soil amendment by agricultural gypsum and plant inoculation with vesicular arbuscular micorrhyzal fungi (AMF) on growth (plant height, dry weight and leaf area), relative water content (RWC%), water retention capacity (WRC), salt tolerance index (STI%), foliage mineral contents (N, P, K, Ca and Na), (K++Ca2+)/Na+ ratio and yield components (number of pods/plant, number of seeds/pod, 100seeds weight, seed yield/feddan and harvest index% ) of dry bean cv. Nebraska grown under salinity conditions. The study was conducted in Dakahlia Governorate at the northeastern of the Delta Egypt during summer seasons of 2019 and 2020. A split plot design with three replicates was used. Salinity significantly reduced all traits, particularly seed yield (around 53.9% losses), except Na%. Magnetized water (MW) and soil amendments sole or in combination had a tendency to increase all studied parameters, except Na%. Moreover, a negative relationship was observed between foliage Na content and seed yield, whereas a positive one was observed between salt tolerance index% and (K++Ca2+)/Na+ ratio which were more reliable in selection criterion in bean plant. Overall, the treatment of magnetized water + gypsum + micorrhyzae is a very important management tool in common bean production in the clay and intermediate salinity soils of northern Delta of Egypt. | ||||
