Field experiment was conduct in the experimental farm of Etay Al-Baroud Agricultural Research Station, Agricultural Research Center, El-Beheira Governorate, Egypt., during the two growing seasons of 2021-2022 and 2022-2023 on faba bean variety Giza 716. The current field study aimed to investigate the effect of different sowing dates (1^st October, 20^th October and 10^th November (and their combination with the foliar spraying applications of calcium-boron (once, twice and three times compared with control). For this purpose, an experiment layout in a split-plot design in three replicates was used. Sowing dates were placed in the main plots and the times of calcium-boron foliar application were randomly distributed in the sub-plots. The results indicated that sowing date 10^th November increased plant heights, pods number/plant, 100-seeds weight, seed yield/fed, seeds content of total protein and seed content of boron in both seasons. Faba bean plants that sprayed three times with calcium-boron recorded the highest plant height, pods number/plant, 100-seeds weight, seed yield/fed, seeds content of total protein, calcium and boron in both seasons. The interaction effect between the sowing date and spraying applications of calcium-boron significantly affected vegetating growth character seed yield and seed quality in both seasons. It could be recommended to sowing faba beans during November with spraying with calcium-boron three times to obtain the highest yield and seed quality in the Delta region.
