Abstract EN

This experiment was conducted in one of Al-Najmi s’region fields, north-eastern Samawa city in 2014 season.

The aim of this experiment was to study the effect of treated organic fertilizer with biological control agents which were Chaetomium elatum and Pseudomonas fluorescens and the interaction between them on Macrophomina phaseolina on growth and productive parameters of mung bean.

Results showed that Organic fertilizer treatment (F1) have a significant values in number of seeds.pod-1, 100 seeds weight, relative content of chlorophyll (SPAD unit), leaf area, and percentage of protein in seeds which were 9.162 seeds.pod-1, 4.000 gm, 25.213 SPAD unit, 55.172 cm2 and 30.072%, compared with the treatment soil only (F0) which gave least average for previous parameters which were 8.025 seeds.pod-1, 3.763 gm, 23.163 SPAD unit, 48.837 cm2 and 28.979%.

Treatment (T6) (C.e.

+ P.f.) gave a highest values in leaf area/plant 62.783 cm2, chlorophyll relative content 27.167 SPAD unit, number of seeds in pod 10.117 seed.pod-1, 100 seed weight 4.600 gm, the percentage of protein per seed 31.400% compared with (T2) treatment (included the pathogenic fungi (M.p.)) which gave 39.633 cm2, 20.633 SPAD unit, 5.583 seed.pod-1, 3.250 gm and 27.267% repectively.
