At 2:30 this afternoon, the President will sign a Memorandum of Agreement with the PNG Government and the Pacific Adventist University for a pilot rice farm.
Minister for Agriculture and Livestock, Benny Allan, will officiate at the ceremony.
Minister Allan has launched the rice farm project in September with the Philippines Ambassador to PNG Bien Tejano.
The 25-hectare rice farm is on track for its first harvest in December.
Ambassador Tejano said then that the first harvest will be tested to see which species is suitable for PNG.
The rice farm is located at 14-Mile, just outside of Port Moresby.
