CIRAD Coconut GIS training in Vietnam: summary and planning
Dr Roland Bourdeix (CIRAD) was invited by the Department of Perennial Crop from the Research Institute for Oil and Oil Plants (IOOP) to organize a training on Geographical Information Systems (GIS) applied to coconut research and development.
Fourteen IOOP researchers and technical staff participated the training. The programme was intended to provide a global overview of the use of GIS in coconut research, and more specifically on the following points: 1) Multi functional landscape management and new trends in coconut conservation and breeding 2) collecting germplasm and integrate geographical and other data using the CGRD (Coconut Genetic Resources Database) and Kobotool box which allows to collect data from cell phones; 3) Managing ex situ genebank accessions and field’s experiment using CDM (coconut data management) and Microsoft Foxpro; 4) the Qgis and Diva-GIS software for managing geographical information. 5) Maxent to predict favorable cultivation zones and 6) Google Earth and other online tools for making interactive geographical representations. All the cited software except Bandicam and Foxpro are free or kindly provided by CIRAD; most of them are open source. Researchers were also trained to video making using Bandicam and Microsoft Movie Maker. Field visits were conducted in research centres and farmer's fields to test the gathering of data with android cell phones, and to prepare a project on assessing a traditional technique from Mekong farmers for reducing the vertical growth of coconut palms. About 10 GB of HD video shootings has been taken and a copy was let to IOOP. A short movie was co-produced during the training. Most of collected information was released online at the URL: http://coconutvietnam.blogspot.fr. Many of the new concept and ideas presented during this training comes from a recent book chapter (1) of an Indian CPCRI book and from the compilation of the Global Strategy for Conservation and Use of Coconut Genetic Resources, all in press. The training was prepared with the help of Dr Geo Coppens and Gaëlle Viennois, CIRAD researchers, and following a dedicated training provided by the CMAEE Join Research Unit in Montpellier, France.

"Coconut bonzai": reducing the vertical growth of Tall-type coconut palms

In 1998, in the framework of an expertise
on collecting strategies (Bourdeix et al, 1999[i]),
the island of Hung Phong (01008N 10622E) in Mekong Delta was visited. While interacting with farmers, it appeared that
what farmers called “Dwarf’ and “Tall” coconut palms did not fit with what was
described in all other countries. More precisely, some coconut palms described
by farmers as “Tall-types” had the typical stem of what is normally called
“Dwarf”: a thin stem without any basal bulb, and very short internodes.
We finally find an explanation (see fig. 1
and 2). In this island, farmers had a very special traditional practice, never
described before (as far as we know).
Figure 1. View of different coconut stems. From left to right: Malayan Dwarf, Compact Dwarf, Indo-Atlantic Tall, Asian-Pacific Tall types of coconut varieties (Photos R. Bourdeix, Côte d’Ivoire). |
When 2 years old, the young tall coconut
palm is removed from the ground, its roots and leaves are cut and, after that,
the palm is planted again in the ground. Such palm will develop stem similar to
those of Dwarf cultivars: no bole, very short internode distance and slow
vertical growth. Farmers said that this practice causes a delay of about one
year on the starting of production but does not affect the future performance
of the palms.

It could be very useful to to scientifically assess this traditional practice, for both
extending the lifespan of accessions in ex
situ Coconut field genebanks, and for proposing a new ways of cultivation
making harvest and field management more convenient and safe.

The Dong Go Coconut Research Centre
The Dong Go Coconut Research Centre
Latitude: 10.21644 Longitude: 106.44994
The centre was visited on 22 and 23th January 2016. It hosts the National Coconut Genebank of Vietnam.
Each tall-type coconut accessions is composed of palms of different ages; the palms are progressively replaced when the first palms dye. The technique to replace the missing palms is based on open pollination within a block composed of different populations of the same variety (for instance Ta Tall). Inter cropping is conducted with various other crops, such as Jack fruit, Papaya, etc... Palms are numbered by a number of row, and a number of palm in the row painted on the stem.
The centre presently serves as a gene bank only for coconut palm. It is advised to strengthen the involvement of the centre in conserving other tree crops. This option has several advantages, including to:
Controlled Pollination Technique
During the past 5 years, the technique of controlled pollination with bagging was not applied in Dong Go Research Centre. Some material remains, such as aluminium isolation box and green bags (French type). All experimentation were conducted using the techniques of open (natural) pollination and assisted pollination (emasculation of dwarf inflorescence in the seed garden and pulverization of pollen coming from another palm). The seed gardens, both in Dong go and Trang Bang, are not isolated by a sufficient buffer zone preventing pollen from outside to reach emasculated inflorescences. So it is advised to use the controlled pollination technique with bagging for research and rejuvenation purposes and to isolate the seed garden with large tree crops for improving the quality of the hybrid seed nuts.

We made an almost complete tour at the borders of the gene bank. At North the centre is delimited by a road and a fence with some open entrance; at South is is delimited by a canal with no fence. At the east side, it is delimited by a small road with no fence, so people may easily come in the gene bank and take coconuts. At the west side it is delimited by house, some of them used by the employees of the gene bank. Land tenure could become a problem. In the past, about a sixth of the available land of the centre (on the West side) was already taken back by the local government to conduct other activities.
The centre presently serves as a gene bank only for coconut palm. It is advised to strengthen the involvement of the centre in conserving other tree crops. This option has several advantages, including to:
• Increase
the global commitment to promote the importance of the gene bank. If more
than one crop is conserved, gene bank will become increasingly mandatory and
committed places for conservation of genetic resources.
• Increase
the visiting frequency to the gene bank. Researchers working in genetic
resources of different crops will meet more frequently, exchange more
information, and cooperate more closely.
• Make
at least part of the gene bank closer to the planting systems used locally by
farmers, as many of them practice inter cropping.
• Ensure
a better agronomic management, especially for inter cropped fields that often
require irrigation facilities and higher fertilization and will serve as
demonstration fields.
• Benefit
from the multi functional use of the landscape. Some coconut plantations,
especially seed gardens, are generally surrounded by other tree crops for
pollen isolation purposes. Instead of planting any tree crops, these buffers
areas can also conserve genetic resources of appropriate species.
A good opportunity could be to extend conservation activities in Dong Go to many other palm species. A large plot and part of the swampy areas could be planted with at least 20 other palms species. When adult, part of these palms could be sold to city and tourism landscaping units who generally buy such palm at a very good price (about 100 USD per meter of stem), and regularly replaced.

Conversely, coconut conservation could also
be integrated into many other agricultural research centres’ programmes within
the tropics. Thousands of coconut palms are planted in these research centres
without considering genetic resources and diversity aspects. Thus, developing
multi functional land use is one of the highest priorities, and hence has thus
recently been included as a new theme of the CGIAR research programme Forests
Trees and Agroforests (FTA).
For instance, in Côte d'Ivoire, West Africa, the CNRA is starting to implement this last approach by duplicating accessions of the International Coconut collection in Côte d’Ivoire. Simulated “coconut islands” will be planted in five of the 13 CNRA research centres scattered around the country. Coconut germplasm will be planted in isolated small units of about one hectare, each conserving only one Tall-type accession and each planted in reproductive isolation in the middle of other tree-crop plantations.

The coconut varieties cultivated in the seed garden are mainly Aromatic Green Dwarf (imported long time ago from Thailand); Macapuno tall from embryo vitro culture; hybrids between Malayan Red and Yellow Dwarfs and Makapuno Tall (pollen imported from the Philippines). During the period 2011-2015, about 160 000 seedlings were produced y IOOP seedgarden. Presently the cost of seednuts is partially supported by the government and they are sold to Vietnamese farmers at 2 USD per piece. Be care that the germination rate of the Aromatic Green Dwarf is generally lower than those of most other Dwarf coconut varieties, and that only 50 to 60% of the AROD seednuts will finally give good seedlings to be planted in the field.
Trang Bang coconut Seed garden |
In some emasculated MYD inflorescences, we saw a strange accumulation of dried sap at the bottom of the female flowers. This could be due to insect attacks. The same was also observed on a Xiem Green Dwarf in an hotel of Ben tre city, so it seems that this pest is widely distributed.
A few MYD palms have a strange habit of the terminal parts of the upper leaves. Boron deficiency was suggested as the cause but, in the opinion of Dr R. Bourdeix, it is very rare to observe boron deficiency on adult palms.
The seed garden is far from the see and some problems of Chlorine deficiency may happen. It is advised to sometimes provide salt to palms to avoid this problem.
Coconut palms are inter cropped with commercial Jack fruit trees, and some large new plots are inter planted with dragon fruit and coconut palms. Some plots are planted with rubber trees. In the future, it could be useful to plant germplasm collection of jack fruit, Dragon fruits and other crops instead of commercial material only. This will need agreements between the various Vietnamese institutions presently working separately on different crops.
