Two field experiments were conducted at the Sakha Acncultura: Research
Station in seasons 2002 and 2003 to study the role of inoculation with a mixture
contains Rhizobium /eguminosarum biovar viceae + Bacillus megatherium (for faba
bean) and Az%bacter spp. + B. mega/herium (for wheat) as well as addition of
farmyard manure', FYM (50 tons/fed) at different levels of nitrogen (' 5 O. 400 and
70 kg Nlfed) on some yield and chemical components and some seeds
technological characteristics under intercropping sercumistances. Results show that intercropping system decreased straw and seed yield of
both crops and achieved lower values in comparison with their corresponding
controls (pure stands): Since. in the intercropping system, the plots are cultivated
with a mixture of two plant crops by a ratio of 50:50%. As a general, inoculation in
combination with the two N-fertilizer levels (15 and 40 kg Nf:ed) relatively increased
straw seed yields of both crops as compared with uninoculated control. The increase
were mostly significant. On the other hand, inoculation, intercropping andlor addition
of farmyard manure increased nodules dry weight (g13 plants) of faba bean. There
were no significant effects between the different treatments and control for
germination %. seed moisture %, radical and shoot lengths of either wheat grains or
faba bean seeds. Weight of 100 seeds of both wheat and faba bean were
significantly increased. Also, microbial inoculation in the intercropping system led to
an increase in volume and density of wheat grains and faba bean seeds. The
results of some treatments were significant. Also, microbia' inoculation and
inlercropping significantly increased crude protein of wheat grains. while faba bean
seeds showed inconsistent pattern. Regarding percentage of ether extract
constituents (E.E) and ash%, there were no significant variations for either wheat
grains or Iaba bean seeds Although,there is no unique trend due to
inoculation,intereropping and FYM on total carbohydrate% of wheat grains as t ey
achieved less values than tradition control ,carbohydrate % of faba bean seeds IS
significantly increase .Intercropping and FYM increased land equivalent ratio (LE~)
The application of FYM strengthed the positive effect of microbial inoculation. It could be concluded that microbial inoculation of both intercropped crops
achieved the highest net return when 40 kg Nffed. was applied (at first season) and
15 kg Nlfed. and FYM (at second seasons) and their corresponding net return values
reached 1783 and 1401( L.E.ffed) respectively.
