Rubeer Tree Types

[Mosha]

Is there a site that explains the pros/cons of the different hybrids? eg RIMM 600. I have googled but can't see anything.

JD 1 are very good quality

[Mosha]

I am not looking to buy, the trees we have RIMM 251 are 5 years old. I just wish to know what advantages one type has over another.

Hello Mosha

Have a look in malaysian rubber researh instatute and the Indain one. They are in English. I found lots of info, but didn't come out any the wiser. If you find any rubber 101 for trees in there tell me. Jim

Talked to a Thai guy this morning, and it's all down to wind resistance. I assume the newer types being the most resistant.

Moshe..

It is my understanding that 251's are supposed to be more wind resistant than 600's...Have heard people say that it is best to plant 251's around the outside and 600's on the interior...

I have all 251's and lost the tops out of 5 of them last month...And they were in the middle of the grove...

Thanks Stoneman. We lost 1 tree last year to a land slip, our trees are on a slope. The wind blows across the slope as opposed to directly on to it. Most folks down here grow 251s only.

CP plans expansion in rubber industry

CP Group is strengthening its upstream rubber industry with plans to sell one million saplings of a newly developed rubber variety next year.

The country's biggest agro-industrial conglomerate is also considering setting up plants in Loei and Phayao provinces to process natural rubber from the saplings the company supplied six years ago to planters. It may also provide additional resources such as higher-technology tapping equipment.

Rubber is among the crops the group has been developing in recent years, along with oil palm for alternative energy.

"Demand for natural rubber will be strong as long as people believe that oil prices will stay high," said Montri Congtrakultien, chief executive and president of the CP affiliate Charoen Pokphand Seeds Co (CPS).

According to Mr Montri, each year Thailand needs to replant about 500,000 rai of the total 16 million rai dedicated to rubber across the country. About 38 million saplings or 76 per rai are needed.

The company aims to distribute about 400,000 saplings of the newly developed JVP 80 variety, which can yield 450 to 500 kilogrammes of latex per rai, higher than the 289 and 400 kg respectively yielded by the RRIM600 and RRIT 251 varieties. The new saplings, at 35 baht each, cost twice as much as other varieties.

"However, JVP80 could start yielding latex in the sixth year, one year faster than other breeds," said Mr Montri. "It will yield as long as 33 to 35 years compared with an average of 25 years for conventional rubber trees."

Business expansion has intensified since CPS completed delivery of rubber saplings for a 1-million-rai rubber project to the Agriculture Ministry from 2003-06. It was obliged to supply 90 million saplings for the project over the period.

About 120,000 trees planted in the first year of the project will be ready for tapping next year, adding an estimated 25,000 tonnes of rubber to the country's total output estimated at 3 million tonnes.To cash in on the new production, Mr Montri said CPS was developing a closed-system tapping device that makes tapping easier and produces more latex.

"More importantly, the device will enable planters to do tapping during rains and it would prevent any possible adulteration, providing clean latex that meets the requirements of foreign buyers," he said.

Buyers from Japan and China have said they would source high-quality rubber from Thailand to use in auto tyres and other industries, he said. The countries import about 860,000 and 1.68 million tonnes of rubber from world markets, of which Thailand supplies 400,000 and 960,000 tonnes respectively.

Mr Montri said the new tapping technology needed another six months of testing before it could be market-ready.

CPS also is considering building plants in the northern and northeastern provinces where the one-million-rai rubber expansion project is concentrated. This would make it cheaper to ship products to buyers in Laos, where many Chinese investors have set up businesses.

CPS also exports about 200,000 saplings a year to neighbouring countries.

Be careful of following any information provided by institutes such as RRIM. The performance of clones very much depends on local conditions and varies greatly according to soil conditions, weather, etc. Probably the best option (if possible) is to look at other local smallholders and review what clones are being used and then plant a variety to reduce impact of any one variable on overall yield.

Many of the newer clones being developed are geared towards timber production, especially in Malaysia where tapping is expensive.

Obviously fast growing trees are more susceptible to wind damage and the best course of action is to implement pruning/topping to improve resitence.

Hello Remix4, this must be rubber week, BP had another article in todays issue about rubber growing in Isan.
