To investigate the effect of sowing date on vegetative characteristics, yield and yield components of faba, 5 faba bean genotypes along with Barekat cultivar (control), a split plot experiment based on completely randomized design with 4 replications was conducted at Agricultural Research Station of Gorgan in 2014-2015. Three sowing dates of 6th of December, 21st of December and 5th of January and Barekat cultivar and 5 large seeded genotypes of G-faba-8, G-faba-10, G-faba-621, G-faba-9 and G-faba 620 were assigned to main-plots and sub-plots, respectively. The results of variance analysis showed that interaction of sowing date ×cultivar was significant for all studied traits except for plant height and tillers per plant. Due to significance of the interaction, it was sliced. The results of mean comparison showed that delay in sowing led to significant reduction in plant height, 100 grain weight, green pods and grain yield. Mean genotype yield for sowing dates of 6th of December, 21st of December and 5th of January was 403.17, 346.04 and 337.15 g.m-2, respectively. At 5th of January, G-faba-621 ،G-faba-620 and G-faba-10 genotype had a higher yield compared to other genotypes. According to the findings, higher yields may be obtained in delayed cropping using genotypes.
