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