Abstract :
A pots experiment was conducted during the
two consecutive winter seasons 2019/2020 and 2020/2021
at the demonstration farm, Collage of Agricultural
studies, (CAS), Shambat, Sudan University of Science
and Technology, Khartoum Bahri Locality, Khartoum
state, Sudan (Latitude15° 40` N and Longitude 32° 23`
E,) to evaluate two botanical aqueousextracts (Neem
leaves, Heglig seeds) and three levels of nitrogen on
S.hermonthica incidence and growth and yield of wheat.
Combined analysis of both winter seasons showed
that Striga emergence increased with the increasing
number of weeks after sowing, Neem 10%, Heglig 10%
and Nitrogen 80 lb/fed., were the best treatments which
achieved significantly lowest number of Striga
emergence, lowest Striga shoot fresh weight (g)/plant,
shoot dry weight (g)/plant. and gave comparable to that
obtained by the Striga free control. Neem 10% and
nitrogen at 80 lb/fed., were the best treatments which
achieved significantly highest wheat shoot fresh weight
(g)/plant, shoot dry weight (g)/ plant and gave
comparable to that obtained by Striga free control
treatment. Nitrogen at 80 lb/fed.Only the best treatment,
which achieved the highest number of tillers/plants and
gave comparable to that obtained by Striga free control
treatment. Neem 10% and nitrogen at 80 lb/fed.,
significantly increased wheat plant height (cm) and they
were the best treatments, which achieved comparable to
that obtained by the Striga free control treatment.
A combined analysis of both winter seasons
indicated that Striga significantly reduced wheat grain
yield by 14.58%. Within all treatments nitrogen at 80
lb/fed, was the best treatment which gave the highest
wheat grain yield and gave comparable to that obtained
by Striga free controltreatment, followed by Neem 10%.
Nitrogen at 80 lb/fed, significantly increased wheat grain
yield (kg/fed.,) by 38.02%.
