EMISI CO2 PADA PERKEBUNAN KELAPA SAWIT (Elaeis guineensis Jacq) YANG DITUMPANGSARIKAN DENGAN TANAMAN PANGAN FASE BERBEDA DI TANAH MINERAL

Abstract

Land changes become oil palm plantations accused of contributing greenhouse gas emissions (GHG) included in the mineral soil, therefore it is very important to gather information in mineral soil CO2 emissions to support mitigation and adaption to climate change. This purpose of this research determine the CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase, as well as to determine the ratio of CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase. This research was conducted in November 2015 to February 2016 in Subdistrict of Tambang, District of Kampar, Province Riau. The method used in this research was Random Block Design with four treatments and replications. The treatments were oil palm-bera, oil palm-corn, oil palm-soy bean, oil palm-intercropping corn soy bean. The research showed that CO2 emissions in the oil palm plantation intercropped with crops (corn and soybeans) in the vegetative phase showed no significantly different. Comparison large of CO2 emissions indicated oil palm-corn vegetative phase.

Response of Immature Oil Palm Growth and CO2 emission on Intercropping System After Replanting

“…Corn root contains endophytic microorganisms which can help provide plant phosphorus (Hafsan et al 2017), and produce IAA growth hormone that can be used for plant growth (Retnowati et al 2018). Furthermore Misbahuddin et al (2018), states that the increased activity of microorganisms in the rhizosphere region is strongly supported by optimum soil temperature conditions. The corn plant used in the intercropping system has a wider canopy compared to other commodities so that it can improve the microclimate around the oil palm plantations.…”

“…Hariyadi et al This increased as a result of high concentrations of nutrition, C-labile and the influence of root exudates (Kuzyakov et al 2000;Misbahuddin et al 2018). Increased of population and microbial activity resulted in increased microbial respiration and CO2 production (Subke et al 2004).…”
