Mineral nutrition and its genetic signature in oil palm (Elaeis guineensis Jacq.): A possible panorama for high yielding materials at low fertiliser cost

Jacquemard J.C., Ollivier J., Surya E., Suryana E., Permadi P.. 2010. In : IOPRI. International Oil Palm Conference (IOPC 2010) : transforming oil palm industry, Yogyakarta, Indonésie, 1-3 June 2010. s.l. : s.n., 36 p.. International Oil Palm Conference, 2010-06-01/2010-06-03, Yogyakarta (Indonésie).

Significant differences in the mineral nutrition have been demonstrated between progenies and the main categories at PT Socfindo (Jacquemard et al, 2002). A new set of investigations has been conducted based on a larger genetic background. It includes 489 progenies observed in 25 genetic trials planted at Aek Loba Timur Project and 63 commercial blocs covering around 3500 hectares dispatched through all the PT Socfindo estates. The leaf contents in the major elements constitute an important genetic signature that allows the characterization and the individualization of the nutritional level of each ALT project families according their genetic background. The observations achieved on the commercial blocs confirm the signature of ALT project derived commercial categories. Some large groups show very distinct characteristics in their nutrient levels such as: Low nitrogen - low potassium Low nitrogen - high potassium High nitrogen - low potassium In addition, some high yielding families express a specific behavior linking calcium to their chlorine absorption, then limiting the potassium absorption. The relation-ship between all these elements is discussed. Providing of high yielding planting material more frugal in fertilizer input is discussed. This possible panorama offered to research and oil palm sector is an added value on the way of sustainable palm oil.
