Abstract
To alleviation salinity stress on germination, growth, photosynthetic pigments, yield and yield components of faba bean; Laboratory using Faba bean (Vicia faba L; Var Nuberia-1) was conducted at Laboratory of Seed Technology Research Department, Field Crops Research Institute, Agriculture Research Canter. As well as Field Experiments were conducted at Experimental Research and Production Station belonged to NRC at El-Emam Malak Village, El-Nuberia Region, El-Beheira Governorate, Egypt during three winter seasons of 2019-2022. Results of Laboratory experiment indicated that significant increases were recorded under application of magneto-priming seed treatment (0.26-28 Tesla) compared to untreated on Germination Index (GI), Seed Germination (G; %), Seed Germination Index (SGI), Germination Energy (GE; %) and Germination Rate (GR; day), root and seedling length (cm), root and seedling dry weight (g), seedling vigor-I and vigor-II of faba bean. The improvement reached 8.82, 8.82, 13.51, 6.87, 21.26, 31.34, 23.09, 21.33, 33.33, 22.99, 34.05 and 33.87% in the above-mentioned characters, respectively compared to untreated seed. Similar positive effect was observed in Mean Germination Time (MGT; day) where the seeds were faster germinated by 5.56% compared to untreated treatment. Under field conditions, irrigation with water passed through magnetic unit (2 inch, 0.26-28 Tesla and produced by NRC) induced positive significant effects on faba bean growth, total chlorophyll, some macro and micro-elements in leaves at 75 days after sowing, yield components, yield (ton fed-1) and nutritional value of yielded seeds at harvest under sprinkler and drip irrigation systems. The percentage of improvement over both irrigation systems reached 10.90 – 22.28, 10.15, 4.99-21.218, 5.56-11.73% in the above-mentioned parameters, respectively. Under conditions of experiments, could be concluded that sowing magneto-priming seeds of faba bean and irrigation with magnetized water could alleviate salinity water stress which resulted in improvement of growth and productivity of faba bean under Nuberia region.
