Cassava and Vietnam: Now and Then

Hoàng Kim

On 21 -25 August, 2017, Dr. Claude M. Fauquet, Director of the Global Cassava Partnership for the 21st Century (GCP21), who cassava trip in Vietnam, do a road trip for five days to visit four key provinces and city Dong Nai, Ho Chi Minh city, DakLak, and Phu Yen. We look at cassava research and production and processing and shared meeting with presentations and discussions on collaboration between GCP21, CIAT and IAS, NLU for the ‘Cassava Conservation and Sustainable Development in Vietnam’.

"I have learned a great deal about cassava in Vietnam and I have a better view of what the near future will be in your country! The road from Daklak to Phu Yen was indeed very interesting and the cassava plantations are quite impressive. I was also quite interested to see the decline in cassava plantations with the competition with sugarcane and pepper, that is quite a concern! And the future will tell us what will happen. And thanks for organizing the visit to the village with the vice-king of cassava and his colleagues, very interesting and very enthusiastic lunch! I hope that his example will teach other farmers to adopt new varieties and that you can help in the process". Dr. Claude said.

After cassa trip in Vietnam. Dr. Claude send email to Dr. Hoang Kim and VNCP group:

"Hoang, I am coming to you, because you know everything in Vietnam and therefore you can probably advise on the next phase.
In our exchange of information prior to my visit, I said that the outcome of such visit was mostly unpredictable, and I believe now that the outcome could be to set-up a regional task force to control CMD in the region!
The following points are clear to me:
1.   The disease is now spreading quickly; mid 2016 the infection was located in a few places in Cambodia and now it is in 5 provinces in East Cambodia and at least one in Vietnam.
2.   The disease is mostly spread by cuttings, although whiteflies are present they play for now a minor, but important role.
3.   There are several initiatives that have been taken; JIICA, CIAT, FAO, ACIAR, but none at the level required to control the disease.
4.   We need to set-up a regional project simply because viruses do not know about borders and there is a lot of traffic of cuttings, at least Cambodia-Vietnam.
5.   Thailand, Laos, Cambodia and Vietnam should all be enrolled in the plan.
6.   GCP21 could serve as a catalyzer to promote the development of this regional plan.
I have contacted all parties, including Thailand (TTDI and KU), waiting for more comments. So far the idea is shared by many people.
My question to you are:
·     Do you share my views about the necessity of the regional plan?
·     Who are the very key Vietnamese institutions and persons in Vietnam who should be involved in the preparation of such plan.
·     Is there anybody in charge of CMD in Vietnam to collect and centralize samples, information…
Many thanks

Claude M. Fauquet,
Director of the Global Cassava Partnership for the 21st Century (GCP21)

Cassava conservation and sustainable development in Vietnam

  Hoang Kim[1], Nguyen Thi Truc Mai[2], Nguyen Bach Mai[3] and Reinhardt Howeler[4]


The project entitled “Vietnam Cassava Conservation and Sustainable Development” has been very successful, as indicated by the results of trials and demonstrations conducted in Tay Ninh, Dak Lak, Phu Yen and Dong Nai provinces, where farmers using the improved technologies and practices boosted cassava yields from 8.5 t/ha to 36 t/ha - a more than four fold increase.

During the period from 1975 to 2015 cassava has become the third most important food crop in Vietnam, after rice and maize. In 2013 the cassava area in Vietnam reached 544,300 ha, with a production of 9.74 million tonnes, and an average yield of 17.9 t/ha. Within Asia, Vietnam is now the third largest cassava producer, after Thailand and Indonesia. Between 1975 and 2000, cassava yields in the country ranged from 6 to 8 t/ha, and the crop was grown mainly for human food and animal feeding.
This changed markedly with the introduction by CIAT in 1988 of some high-yielding breeding lines and varieties from Thailand. Two varieties, Rayong 60 and KU 50, were selected for release in 1993 and 1995 and were named KM60 and KM94, respectively. During the 1990s and the first decade of the 21st Century, Vietnam produced several new cassava varieties, initially mainly selections from sexual seed from Thailand and CIAT, such as KM95-3, SM937-26, KM98-1, KM98-7, but our breeders also made crosses that resulted in the release of the latest new varieties: KM140, KM98-5, KM419 and others. The breeding and adoption of new varieties as well as the development and adoption of more sustainable production practices resulted in a complete transformation of cassava, from a poor man’s food crop to a highly profitable industrial crop. More recently, new advances in cassava cultivation techniques have focused on key demonstration sites in the provinces of Tay Ninh, Dak Lak and Phu Yen using mainly KM419 as a very promising short-duration cassava variety with a fresh root yield of about 35-55 t/ha (28% higher than KM94) and a starch content of about 28-31%. This and other new varieties, together with new advances in cassava cultivation techniques, have yielded spectacular results in trials organized in those three provinces.

The Vietnam National Cassava Program (VNCP) has introduced various methodologies, named “6M” and “10T”, as well as Farmer Participatory Research (FPR), as collaborative experiences that helped to bring advanced technologies into production for millions of poor farmers. This included the s
election of high-yielding varieties and the testing and selection by farmers of locally appropriate technologies. Cassava in Vietnam has great potential but also faces big challenges. At the national level, cassava has become one of the main export crops, which has provided for millions of smallholders an opportunity to increase their yields and improve their standard of living.

Key words:
Cassava, production, utilization, cultivation techniques, achievements, lessons and  challenges, conservation, sustainable development, Vietnam.

The cassava variety KM 419 was developed from the cross combination BKA900 x KM 98-5.  KM 419 has the advantage of short duration  with fresh root yield 34.9 – 54.9  ton/ ha (higher than KM 94 about 27.7- 29.6% ), good root shape with white flesh, high adaptability to various production conditions, starch content 27,8 - 30,7%, starch yield about 10,1 -15,8 ton/ha and root dry matter content about 15,6-21,6 ton/ha for 7-10 months after planting ( KM94 starch content 26,0-28,3 %, starch yield about 6,4- 9,5 ton/ha and root dry matter content about 9,0- 13,2 ton/ha for 9-11 months after planting). KM419 was moderately susceptible to cassava bacterial blight. Production area of KM419 in the Tây Ninh, Dong Nai, Dak Lak, Phu Yen in 2013 was up to more than 50,000 ha. KM419 was proposed by the Nong Lam University in Ho Chi Minh city (NLU) and Thai Nguyen University of Agriculture and Forestry to be main production in the Southeast, Central Highland, North and South Central Coast and Northeast & Northwest of Vietnam.

Key words: Cassava  KM419, high starch yield, cassava breeding, Vietnam.
