Asystasia gangetica (L.) Anderson, cover crop, oil palm plantationAbstract
Asystasia gangetica (L.) Anderson is a kind of weed often found not only under immature oil palm plantation but also under mature oil palm plantation. A.gangetica can grow well in soil with a low fertility rate and under shaded condition, so that it can be used as a cover crop under mature oil palm plantation with different ages.
The experiment was conducted under mature oil palm plantation the age of 5 years old (TM-2) and 17 years old (TM-14), in Cikabayan University Farm, IPB Bogor, West Java, from March 29 to 21 September 2014. The result showed that A.gangetica can be utilized as a cover crop under mature oil palm plantations (TM-2 and TM-14) since it is able to grow well in the two locations, improving soil physical and chemical properties and increasing soil moisture and nutrient availability through the rapid litter decomposition (decomposed within 30 days) and the release of litter nutrients nearly 100% within 30 days. Therefore, A.gangetica can be used for the implementation of sustainable oil palm plantations in accordance with the principles and rules of the RSPO and ISPO.
