Abstract:
The experiment conducted in season 2016/2017 in the experimental farm of the college of agricultural studies Sudan University of science and Technology - Shambat, to study the effect of different fertilizers (compost, urea and Di ammonium phosphate) on growth and yield of three genotypes of the sunflower (V1=0.398, V2=Sirana and V3=MR1362). The experiment carried out at factorial experiment ranged in randomized complete design (RCBD).
Traits under study included indicators of growth and yield (plant height (cm), number of leave per plant, leave area (cm2), stem diameter (cm), disc diameter (cm) and seed yield (kg/ha). the results showed that significant differences in plant height (cm), number of leave per plant, leave area (cm2), stem diameter (cm), and seed yield (kg/ha) but no significant differences among treatments in disc diameter (cm). Also the interaction between treatments and genotypes had no significant difference in all parameters except the yield.
