Abstract:
A field experiment was conducted at two experimental sites at Khartoum, Sudan, season 2016-
2017, to study the effects of Trichoderma harzianum, Bacillus megatherium var. phosphaticum
(BMP), Rhizobium leguminosarum biovar viceae strain (TAL1399), Nitrogen and Phosphorus
fertilizer (two levels each) on Orobanche crenata incidence and faba bean growth and yield.
Nitrogen was applied as urea 95.2kg/hectare (N1) or 190.4kg/hectare (N2) and phosphorus as
triple super phosphate 95.2kg/hectare (P1) or 190.4kg/hectare (P2), Treatments were laid out in a
Randomized Complete Block Design (RCBD) with four replicates. Results showed that O.
crenata displayed maximum emergence (76.50 plants/m2
) in the untreated control at 100 days
after sowing, the combination of T. harzianum + BMP+TAL1399 + fertilizers both levels
significantly (P<_0.05) reduced O. crenata emergence as compared to the control at both sites.
Application of T. harzianum alone or in combination with BMP+TAL1399 + N2P2 significantly
(P?0.05) reduced O. crenata dry weight as compared to the control, irrespective to the site. T.
harzianum alone or in combination with N1P1 or BMP+TAL1399+N2P2 and the combination
with BMP+TAL1399+N2P2 significantly (P<_0.05) increased plant height as compared to the
infested control. The combinations of T. harzanium+BMP+TAL1399+N1P1fertilizers
significantly (P<_0.05) increased number of pods per plant, seeds per pod, 100 seed weight and
yield (kg/ha), as compared to the control in both sites. |
