1) Cleft grafting is a method of joining a rootstock and scion for asexual propagation of jackfruit. It allows for selecting quality planting materials that retain the characteristics of desired varieties. 2) The document describes the steps for cleft grafting jackfruit, which includes selecting healthy rootstocks and scions, making cuts, inserting the scion, securing it with tape, and post-grafting care. 3) Best practices for a jackfruit nursery include using sterilized media and tools, quarantining new materials, controlling pests and diseases, and following hygienic measures to prevent the spread of phytophthora disease.

Balinsasayao, Abuyog, Leyte during the 5th Agriculture & Fishery Techno Forum, August 14-16, 2019.

2. • Jackfruit is a banner/flagship
commodity in EV thru the DARFO 8’s
HVCP since 1995.
• Jackfruit is commonly grown by small
holder farmers in EV.
• EV consistently ranked within the top
ten jackfruit producing regions in the
Philippines
• There’s a promising and commercial
potential and scalable agribusiness
investment opportunities across the
value chain segments for Jackfruit.
• Thus, DA intensified its fruit collection,
evaluation of promising jackfruit
varieties in the region leading to its
identification of an NSIC-registered
jackfruit variety, the EVIARC Sweet.
Why Jackfruit for Eastern Visayas
(Region VIII)?

3. The now famous
EVIARC Sweet?
EVIARC SWEET is a jackfruit variety registered
with the Bureau of Plant Industry-National Seed
Industry Council (BPI-NSIC) in 2007 with
Registration No. NSIC 2006 Jf 05 (EVIARC Sweet)
dated April 11, 2007
Package of Technology developed by the
Department of Agriculture Region 8
Supported by DA-BAR and PCAARRD
EVIARC stands for Eastern Visayas Integrated
Agricultural Research Center (EVIARC), the
owner, developer of this technology.

6. Cleft Grafting
• is a process of joining together a
rootstock and a scion until they
are united permanently.
• most common commercially
used method of asexual
propagation.

7. Advantages of cleft-
grafting as asexual
propagation
 Can select quality planting
materials
 Retain the characteristics of
the mother plant
 Bear fruits earlier
Easier to harvest and
economical
Easier to estimate the number
of plants per hectare due to its

Before culturing the
jackfruit scion,be sure that
the mother plant is healthy &
vigorous

32.  Sources of

(scions) should
come from a

GRAFTING

38. STEPS:
1. Select healthy rootstocks
(3-5 months old)

39. 2. Make an incision on the
greenish portion of the
rootstock.

40. 3.Make a cut
of about
1.5cm
enough to
the“V-shape
cut”of the
“scion”.

41. STEP 4.
Select a
healthy
scion
almost the
as the
same size
of the
rootstock.

42. STEP 5.Hold
firmly the
scion and
make a
wedge cut
about 1.0-
1.5cm long
on the basal
section.

43. STEP 6.Insert the wedge on the
rootstock and secure firmly with a
plastic tape.

44. Step 7.Wrap the scion
with a lose wind of
plastic strip

45. Step 8. After 17-18 days from grating,unwrap

plants to the
screen house
or netshed for
conditioning
1-2 weeks after
removal of ice
candy
wrapper.

and (B) side view where all infested/diseased fruits and
other organic debris are stored for composting to produce
organic fertilizers.
 Provision of concrete and covered
composting structure or compost pit;

61. CHEMICAL & FERTILIZER BODEGA

62.  Sources of
propagules
(scions) should
come from a
certified scion
trees free from

disease;

63.  Use sterilize potting mixes;
 Walkways, alleyways and surfaces
must be paved to prevent the exposure
of pot, plants, tools and irrigation
hoses to contaminated soil

tools, and storing them where there is
no chance of contamination by soil and
water;

include:

64.  Regular testing of irrigation water;
 Prevent introduction of infested soil
and water in the nursery
 Quarantining newly acquired
propagating material
Other best nursery practices
include:

65.  Periodic/regular inspecting, roquing,
containing and destroying of diseased
plants;
 Restrict access to all nursery areas to
prevent the introduction of contaminated
soil and water;
