| Abstract | ||||
| 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. | ||||
