“…Increments in yield and yield parameters in plants treated by seaweed extract foliar application may be related to beneficial role of seaweed extract on enhancing growth, fruit production as it contains boron that is responsible for flowering and pods filling in addition to activation of antioxidant enzymes and scavenging of ROS radicals thus consequently increase plant tolerance against salinity, increasing yield productivity and its chemical component from protein and carbohydrates. These results are in agreement with that recorded by Elshalakany et al (2023).…”

HE COUNTRY has a tendency to secure food supply through vertical expansion by increasing productivity per unit area, especially under conditions of stress such as salinity, in addition to horizontal expansion in new lands that may be saline or irrigated with groundwater of high salinity which affects productivity especially for sensitive crops like beans. So, two field trials were conducted to study the effect of four cobalt foliar application rates (0 ppm (as control), 5 ppm, 7.5 ppm and 10 ppm) as the main plots and four bio-stimulant treatments (control, potassium humate, potassium fulvate and seaweed extract) as foliar treatment in the sub main plots on faba bean growth, yield and its components which cultivated under salt affected soil. During the winter seasons of 2021/2022 and 2022/2023, a split plot design was used. The obtained results could be summarized as follow: Foliar application of cobalt at 10 ppm concentration recorded the highest values of the vegetative growth, yield and its components compared to the other cobalt rates. Application of cobalt at 10 ppm concentration increased chl. a+b by 21.20%, proline content by 9.65% and seeds yield by 6.86% comparing with control treatment. At the same time foliar application of seaweed extract had a superior effect on all studied parameters with relative increments as example 41.84%, 45.41% and 13.63% for chl. a+b, proline content and seed yield, respectively compared to the other foliar treatments of bio-stimulants. The interaction among cobalt at 10 ppm concentration and seaweed extract achieved the highest values of vegetative growth criteria, yield and yield components of the tested plant. Economically founded that combination of cobalt at 10ppm and potassium fulvate application a viable alternative to existing treatments for increasing agricultural output and farmer revenue.
