Abstract
This study was conducted at Altyba research station which belongs to GCSAR(1) during the growing season 2011/2012 to study the effect ofbacterial inoculation and Sowing date on some productivity and qualitative traits of green and dryfaba Bean. The Experiment was laid according to Split-Split-plot design, with Tow variety of faba bean (improvement Baladi,Histal), the Experiment wascultivate in tow planting date (30/11 and 15/12/2011), the amount of seeds had been divided into two parts: while the first part (half of seeds) was treated with bacterial incoulator (rhizobium), the second left (another half of seeds) without treatment, as control.with three replicates into every one.
The results showed that seeds inoculations with (Rhizobia leguminosarume) led to significant increase in the yield medium of green pods (13510 kg.h-1) and dry seeds (2152 kg.h-1), andit,s components such as 100 green seeds weight (346 g), and the green pods number in plant (21.3pod/plant) .also significant differences noticed in branch number in plant (5.36 branch/ plant), and days number until begun flowering (53.85 day), also led to significant increase in green and dry seeds respectively content of protein (6.54, 27.27 %), compert with un incoulator plant treatment respectively (12690 kg.h-1, 1920kg.h-1, 322 g, 15.9 pod/ plant, 4.64 branch/ plant, 55.8 day, 5.36%, 25.36%).
Results showed that the first planting (30/11) led to significant effect in the yield of green pods (14498 kg.h-1) and dry seeds (2041kg.h-1)and 100 green seeds weight (350.3 g),compert with scound planting respectively (11702kg.h-1, 1931kg.h-1 , 317.5 g).
Interaction results between inoculation and planting date showed that significant increase in the most studied traits, especially the average yield of green pods (15303 kg.h-1) and dry seeds (2372 kg.h-1) for the local variety (Baladi) when sown on the first planting date (30/11) and treated with bacterial inoculation.
Key words: Bacterial inoculation, Sowing date, Broad beans., Yield, Rhizobium.
