PETALING JAYA - Farmers in Malaysia's major vegetable-farming regions are worried the wet, gloomy weather will affect their production, The Star reported.

With 2,000 farms in Cameron Highlands, making it the country's largest production centre for vegetables, farmers in the hilly region in Pahang state are worried the incessant rain and lack of sunshine for their vegetables could affect their production by 10 to 15 per cent.

Temperatures across the country have dipped below the norm in recent days.

On Saturday, the temperature in Cameron Highlands fell to 13 deg C, raising concerns that the colder-than-usual weather could affect vegetable and flower production.

Daily afternoon showers are also expected for the week ahead in Cameron Highlands, according to the Malaysian Meteorological Department.

Cameron Highlands Vegetable Growers Association secretary Chay Ee Mong said the recent cold weather may slow the growth of vegetables and flowers, but prolonged rainy and cloudy weather is a greater concern as it can affect vegetable production by 10 to 15 per cent.

"Too much rain and less sunlight will affect production," he said.

However, Chay said it is too soon for consumers to worry about prices during Chinese New Year, as the festive season is still a month away.

Chay said that this is not the first time Cameron Highlands, which usually sees temperatures of around 18 deg C, has experienced lower temperatures than usual.

"Farming activities are still going on as usual here. Workers will just need to wear more clothes to keep warm," Chay said.

"People are more concerned about the cold weather now because it is the first time that the temperature in certain low-lying places has also dipped to a low of 22°C," he added. "The impact will not be significant for now but still, we have to see how things go, moving forward."

Cameron Highlands Floriculturists Association president Lee Peng Fo said the prolonged cold weather with temperatures lower than 15 deg C could also slow the growth of flowers and affect their blooming time.

"If the cold weather continues for more than 10 days, the impact will be significant. Production could be 10 to 20 per cent lower," he added.

"But for now, we have to wait and see how long the colder weather lasts. It has been colder than usual for about a week."

Over in Johor, farmers are reporting a 30 per cent drop in yield, which has resulted in the the prices of some vegetables going up by 50 to 100 per cent.

Things are not looking up for them, with the weather agency forecasting rain in Johor's vegetable production areas such as Tangkak, Johor Baru, Simpang Renggam and Pulai for most of the week, except for two sunny days on Monday (Jan 15) and Tuesday. The temperature in those areas is forecast to range from 22 deg C to 30 deg C.

The Federation of Malaysian Vegetable Farmers Association president Tan So Tiok said the cold weather was not good for leafy vegetables.

"Vegetables need a warmer climate with lots of water. My area, Ledang, is experiencing temperatures of 22 deg C, which is not suitable," he said, adding that Johor is one of the country's top vegetable producers after Cameron Highlands.

Among the vegetables that have gone up in price is brinjal, at RM7 (S$2.34) per kilo compared with RM3 previously.

Leafy vegetables that cost more now include bayam, kangkong, kailan and sawi.

Asked if there is a shortage of vegetables in the market, he said there is no major shortage so far, nor has there been any disruption in exports to Singapore.

"We hope the weather will improve. It has been raining for almost a week with no sunshine. In Ledang, the daily vegetable output is down from 70 tonnes to 50 tonnes," he said.

He added he is optimistic that the situation will return to normal before Chinese New Year.
