Effect of the biofertilizers and the methods of its addition on the growth and yield of eggplant (solanum melongena l. )‎ under greenhouse conditions

Abstract EN

Research was conducted at Al-latifia Research Station of Plant Breeding and Improvement Center, Agricultural Research Directorate, during spring season of year 2016 to study the effect of some biofertilizers on growth and yield of Eggplant plant under greenhouse conditions.

A factorial experiment was designed in Randomized Complete Block Design with three replicates and the means of traits compared by L.

S.

D.

at 5% level.

The main factor included methods of adding biofertilizers to seeds (A1) and transplants (A2).

The secondary factor was biofertilizers included: without adding any Biofertilizer (control) (T0), Pseudomonas fluorescence, (T1), Azospirillum brasilense (T2), Bacillus subtilis (T3) and Azotobacter chroococcum (T4).

The results showed that Azotobacter chroococcum treatment significantly increased the plant height (87.70 cm) compared with (57.70 cm) in the control treatment.

Moreover, Azotobacter chroococcum treatment showed significant increases the yield per plant and the total yield which were, (1000.00 gm.

plant-1 and 899.00 Kg.

greenhouse-1) respectively in comparison with the control treatment which were (553.00 gm.

plant-1) and (498.00 Kg.

greenhouse-1) respectively.
