Introduction of Diverse influential factors for the growth

The Arenga pinnata is one of the plants that do not require special climatic conditions and soil to support its growth. Central Java Forestry Service (2011) said that the Arenga pinnata might flourish in the midst of other trees and shrubs, in the plains, hillsides, valleys and mountains up to 1,400 meters altitude. Plant roots that can reach a depth of 6-8 meters can withstand erosion, as well as very effectively attract and hold water. Furthermore, Hidayati (2009) said that this tree does not need the fertile soil, Arenga pinnata can live in all soil conditions (clay, calcareous soil and sandy soil). Arenga pinnata that grows wild in the South Tapanuli Regency of Indonesia helps farmers in the plantation. 

Although palm trees are also a source of income farmers, but research is still paid attention less from the local government. As a consequence, the Arenga pinnata plant is only managed by the small communities by relying on tradition cultivation. Therefore, the majority of livelihoods of the people of South Tapanuli are farmers and gardeners. The forest grows a lot of wild Arenga pinnata. 

For example, it was found that in Pasar Minggu Village of South Tapanuli Regency with a height of 500 above sea level, the Arenga pinnata of the farmers produce sas much as 25 liters/day; the morning harvest yield 15 liters and the afternoon 10 liters / stem. Based on the problem above, it is necessary to study about the Arenga pinnata plant in relation with soil nutrient status of pH, C-organic, N, P, K and Mg. This experiment was carried in South Tapanuli Regency where we found many farmers cultivate the Arenga pinnata.
