1. Introduction:
1.1 Background
• Banana is mainly cultivated for its
1-1 fruit which can either be eaten ripe
(dessert) or cooked
• The ripe fruit is a good source of
vitamins A, B6 & C and
potassium, while cooked one is
rich in carbohydrates
• It can also be processed into flour,
canned slices, jam, jelly and beer
• The popularity of the crop makes it
a good cash crop for smallholder
farmers
• The foliage and pseudo-stems

3.1.2 Sword Suckers
2-8 • Most farmers use sword
suckers obtained from own
farm or from neighbors to
extend existing or establish
new banana orchards
• The common farmer
practice of using infected
sword suckers has
continuously perpetuated
the spread of banana
diseases and pests
• To mitigate this problem,

sword suckers can be used as
the propagation material
• Sword suckers are shoots with
1 2 narrow leaves with height of
about 1 m and 15 cm diameter
3 4 at the base
• Sword suckers are sourced
from existing Banana orchard
therefore it is necessary to treat
the suckers with hot water to
eliminate nematodes &

MOALF/SHEP PLUS
4. Cultural Practices:
4.1 Land Preparation
(GHCP&PHHT20: Q6)
• Before planting, deep soil cultivation by ploughing &
harrowing is recommended
• The field should be free of trees, bushes and especially
perennial weeds
• A planting hole measuring 60 cm x 60 cm x 60 cm is
recommended although this may vary depending on water
availability
• In dry & semi-arid areas, it is recommended to use holes
measuring 90 cm x 90 cm x 90 cm
• Bananas cannot withstand stagnant water hence soil
should have good drainage
18
MOALF/SHEP PLUS
4. Cultural Practices:
4.1 Land Preparation
4.1.1 Recommended Spacing
(GHCP&PHHT20: Q10)
• Short Varieties: 3 m x 3 m (444 plants/acre)
• Medium Varieties: 3 m x 4 m (333 plants/acre)
• Tall Varieties: 4 m x 4 m (250 plants/acre)
4.1.2 Fertilizer Application Method & Rates
(GHCP&PHHT20: Q11)
• The top soil and sub soil should be kept separate
• Mix the top soil with 2-3 debes (20-30 kgs) of well
decomposed manure and 200 g of Triple Super Phosphate
(TSP)
• Refill the hole with the top soil first followed by the sub soil
• Allow it to settle for at least 2 weeks before transplanting 19
MOALF/SHEP PLUS
4.2 Transplanting • Transplanting should be done
when tissue culture seedlings
are about 30 cm and have
3-3 produced at least 5 healthy
leaves
• To ensure good anchorage, a
sucker or seedling should be
placed 30 cm deep in the
planting hole
• A heavy cover of mulch should
be placed around each plant to
conserve soil moisture
• Under rain fed conditions,
planting should be carried out at
the onset of the rains
Photo: SHEP PLUS
• However, if irrigation water is

4.3 Crop Management suckers from one stool so that at
any moment a stool has only 3
4.3.1 De-suckering suckers:
3-5 – One bearing sucker (mother
plant)
– One half-grown sucker
(daughter plant)
– One sprouting sucker (grand

Poorly Managed Banana Stools • The surplus suckers are dug out
with corm, and can be used as
3-6 planting material
• In order to prevent sprouting:
Insert a peg in the growing part
• The process should start 2

MOALF/SHEP PLUS
4.3.2 Propping
3-7 • It is the process of supporting banana
plants which have mature or immature fruit
bunches to prevent them from lodging
• A pole with a V-shape end is placed under
the bunch to support it
3-8 • The prop should be placed carefully to
avoid fruit injury
• The major varieties which require propping
are: Grand Nain, Williams, Valery, Giant
Cavendish, FHIA series, Ngombe etc.
Propped up

4.3.3 Trimming of Old Dried Leaves
• This activity is useful since it ensures light
penetration in the orchard and helps reduce
3-9 certain leaf diseases and reduces injury
caused to bananas by the dry leaves during
windy periods
• All dry/dead leaves which hang down the
sides of the pseudo stem need to be removed

at least twice a year (Each pseudo stem
Neglected
Stool with should have 7 leaves at any one time)
Dried Leaves • Trimming;
3-10 – Ensures light penetration in the orchard
– Helps reduce certain leaf diseases
– Reduces injury caused to banana fruits by
the dry leaves during windy periods

MOALF/SHEP PLUS
4.3.4 Removal of Male Bud & Bagging
• The male bud or navel should be
3-11 removed after bunch formation is
complete
• The advantages of removing the
male bud include; increase in yield,
uniformity of hands and reduced
thrips attack
Before Removal Note: Tools used during removing
male buds and pruning need to be
3-12 disinfected
4.3.5 Bunch Covering (Bagging)
• Covering banana bunches with
special polybag in order to protect
them from being attacked by thrips
and other insects
After Removal • Fasten maturing bunches 24

MOALF/SHEP PLUS
4.4 Water Requirement
(G20: Q12)
• Banana plants require a
minimum of 1,000 mm of
3-13 rainfall annually
• Irrigation is therefore
necessary where the rainfall
received is less than this
amount
• Water is critical at flowering
• Therefore, in drier areas,
supplemental irrigation may
Banana Orchard Under
Irrigation
be necessary during this time
40-60litres/stool weekly (in
two splits) 25
Photo: SHEP PLUS
MOALF/SHEP PLUS
4.5 Managing of Weeds
(G20: Q13)
• Orchards should be kept weed-free
through either hoeing, mulching or
herbicides
3-14 • Since bananas are shallow-rooted,
care should be taken during
weeding to avoid root injury
• A well maintained heavy mulch
cover will suppress weed growth,
retain moisture & provide humus
for a good soil structure
• The orchard can also be kept
weed-free through inter-cropping
Weed Management Through • Use of herbicide such as Paraquat
Mulching Dichloride (Gramoxone®,
HERBIKILL®) or Glufosinate -
Ammonium (Basta®) is also
26
effective

MOALF/SHEP PLUS
4.6 Top-dressing (2/2)
4.6.1 Top-Dressing by Fertilizer
• Fertilizer should be applied twice a year during the
rainy season
• Apply 200g of CAN per stool. The top-dressing
fertilizer should be applied in a band 60cm away
from the plant
• Or, an NPK fertilizer rich in K such as Mavuno
Banana (10-3-20+TE) 250g per stool
• 2 – 4 debes (20-40 kgs) of well decomposed
farmyard manure is applied per stem per year
before the rains. This is applied on the outer
diameter of the canopy and incorporated into the
27
soil carefully to avoid root damage
