Abstract

This investigation was carried out at the two experiments at Sids
Research Station, Beni -Suef Governorate during 2010/2011 and
2011/2012 growing seasons. Twenty faba bean (vicia faba L.) genotypes
were used included 14 ones promising Orobanche tolerant genotypes and
6 cultivars,i.e., three tolerant and the three susceptible. Each experiment
was included of three sowing dates 20th October, 5th November and 20th
November in both seasons,was conducted in Orobanche infested field.
Results showed that number and dry weight of Orobanche spikes were
significantly affected by the sowing dates. The late sowing date on 20th of
November reduced both number and dry weight of Orobanche as
compared with the two earlier sowing dates (20th October and 5th
November). The best results recorded for most faba bean characters were
for sowing in 5th and 20th of November, respectively. They significantly
increased seed yield (t/fed) over the sowing date in 20th October by
103.9% and 63.6% respectively. The interaction between sowing dates
and genotypes on Orobanche dry weight were significant in two growing
seasons. Results indicated that there were significant differences between
faba bean genotypes under Orobanche infestation field for each of the two
growing seasons.
