Abstract
Two pot experiments were carried out during two growing seasons (2010/2011 and 2011/2012) at Seed Technology Research Unit, Seed Technology Research Department , Field Crops Research Institute. The aim of these experiments were to study the response of faba bean namely (Sakha1) growing in saline soil (2000 mg/L, 4000 mg/L, 6000 mg/L and 8000 mg/L) to application of some growth promoters (Salicylic acid 250 mg/L, Ascorbic acid 250 mg/L, α –Tocopherol 100 mg/L, Humic acid 1000 mg/L, Yeast extracts 2000 mg/L) as seed soaking, foliar spraying or seed soaking and foliar spraying together. The effect of these promoters on faba bean yield and it`s components were recorded. Results indicated that salinity stress levels at 8000 mg/L followed by 6000 mg/L, 4000 mg/L and 2000 mg/L respectively, compared with control treatment (320 mg/L) were the most effective in decreasing all yield and it`s parameters (number of pods / plant, pods weight / plant (g), number of seeds / plant, seeds weight / plant (g) and 100- seed weight (g)). While, applied antioxidants promoters ASA 250 mg/L followed by SA 250 mg/L, Yeast extract 2000 mg/L, Humic acid 1000 mg/L and Tocopherol 100 mg/L compared with water as control applied as (seed soaking, foliar spraying or seed soaking and foliar spraying together) were the most effective in increasing all yield and it`s parameters. It could be seen that applied antioxidants as growth promoters hardly decreasing the harmful effects of salinity stress on yield and it`s components of faba bean plants.
