Abstract:
A field experiment was carried out at Sudan university of science and technology
college of Agriculture studies Shambat, winter season ( 2017 2016 ) to study the
effect of organic and inorganic fertilizers on growth and yield of some sunflower
(Helianthus annuus L. ) genotypes. The experiment was designed at factorial
experiment in randomized complete block design with three replications and used
three genotypes (V1= 0398, V2=SIRANA, V3=MR1362) and two types of
fertilizers: Organic (compost), Inorganic fertilizers (Urea and
Diamoniumphosphate). The parameters ware taken from the experiment is (plant
height (cm), number of leaves, stem diameter (cm), leaf area (cm2), disk diameter
(cm), 100-seed weight (g) and yield (ton/ha).
The results showed that significant different among the fertilizers in: (plant height,
number of leaves, stem diameter, leaf area, 100-seed weight and yield (ton/ha) butno significant different in disk diameter (cm). also that significant different among
genotypes in number of leaves and yield but no significant different at all the rest
of parameters and no significant different at interactions in all parameters except
the yield (ton/ha).
