Abstract:
The study consists of experiment at two different locations in River
NileState.These locations were Hudeiba (Research Station) and Aliab (Bashaier
area. The study was conducted during the period 2009-2011 to evaluate the effects
of urea, NPK compound and organic fertilizers (poultry and farm yard manure)
on banana plants, Cavendish and Grand Nain cultivars. The fertilizers were
applied alone and in combination. Applications were 400gm urea and 200gm
NPK in four doses organic fertilizer was applied as 10kg compost and 5kg poultry
manure, Banana suckers were planted 3x3m spacing and 6x4m basins. There
were 4 replication. Data collection consisted of vegetative growth, fruit yield and
TSS contents of fruits. In fruit parameters recorded were length, width of
pseudostem and number of leaves. The study indicated a significant increase in
pseudostem length and small increase in width and number of leaves.
In Hudieba location after first readings the plants stunted due to the characteristic
of heavy clay soil, which hinder growth of roots, besides the lack of aeration.
In Bashier location the experiment were carried in two seasons. There were highly
significant differences in pseudostem length in the two cultivars due to fertilizer
treatments especially chemical and organic fertilizers, the cultivars also
showed significant in differences between them and significant differences due
to fertilizers during vegetative growth. Regarding pseudostem width these was
significant in difference until 120 days from planting where after there was significant
difference, due to all treatments ,but no significant difference due to the
combination between cultivars and fertilizers.
The study indicated significant differences in leaf number due to fertilizers and
cultivars and also the combination between them.
IV
There was significant difference due to urea, NPK and poultry manure and compost,
treatments for both cultivars in the two seasons compared with the control.
The results showed that there were highly significant increase in growth resulted
from all fertilizer treatments, reflected in earlier shooting198days in the main
crop, 142days in the first ratoon and shorter time to flowering and to harvest
35days in the main crop and 32 days in the first ratoon in Dwarf Cavendish
compared to Grand Nain cultivars in the two seasons. The results indicated that
addition of urea with compost and urea with poultry manure resulted in significant
differences in yield represented by bunch weight, fingers weight, hand
number in bunch, finger in hand compared with the control. Grand Nain was
more response to the Dwarf Cavendish.
The results showed that total soluble solids (TSS) increased significantly due to
the treatment of fertilizer and were highly significant between the two cultivars
in the two seasons, so the effects of compost +Urea on TSS in green fruits and
TSS in ripe fruits indicated that Grand Nain is more responsive than Dwarf
Cavendish.
