JAKARTA, Jan. 19 (Xinhua) -- Indonesian government has taken measures to settle problems in palm oil replanting scheme in a bid to boost yields, a minister said here on Friday.

One of the major problems is that many of growers have not received certificates of their lands which is necessary to recieve financial support from banks.

Indonesian Minister of Agrarian Affairs and Spatial Planning Sofyan Djalil said that absence of the certificate has been an obstacle for the growers to borrow money from bank in a bid to finance their new planting plan.

"To conduct replanting program it is required to get land certificates. This is very important," he said at chief economic ministry office.

Sofyan said that a coordination meeting attended by chief economic minister Darmin Nasution to solve the problem was carried out on Friday.

President Joko Widodo has launched a campaign to distribute millions of certificates to farmers in an effort to ensure them get financial support from banks.

Indonesia has set a replanting plan for 4.7 million hectares of palm oil plantation in the country aimed at boosting fields, according to agriculture ministry.

Many of palm oil plants has been aging and have low seeds quality, it said.

Productivity of the country's palm oil plantations is only 2 to 3 tons per hectare lower than that of 12 tons per hectare in Malaysia.

Indonesia is a world's major producer and exporter of palm oil.
