Elaeis guineensis is one of the potential carbon sequestering perennial crop by biological means. It has helped in the mitigating global warming and climatic fluctuations. The main objective of our study is to evacuate the hidden potential treasure of oil palm in carbon sequestration and vegetable oil yield. In this study we selected Tenera hybrids oil palm plantations in Coimbatore district of Tamil Nadu with standard management practices. It had been selected in the year 2019 and assessed for carbon sequestration potential and Fresh fruit bunch yield by non-destructive carbon stock assessment methods and standard estate practices for harvest. In our study the carbon sequestration is higher in trunks found to be 15.3 t C/ha (tons carbon per hectare) in 5 years and 26.6 t C/ha in 10 years while roots sequestered carbon for about 4.0 t C/ha in 5 years and 6.93 t C/ha in 10 years plantations. The fronds sequesters about 1.39 t C/ha in 5 years and 2.1 t C/ha in 10 years oil palm plantations while the fresh fruit bunch yield in 5 years and 10 years plantations were found to be 7.60 t/ha/year (tons per hectare per year) and 12.31 t/ha/year respectively. The present study evidenced that the biomass production and fresh fruit bunch yield in oil palm proportionally increases with the age group. This study holds that the higher biomass production which increases carbon sequestration and yields in oil palm helps in altering of the microclimate and to increase the economic benefits of farming communities.

Planting Distance

Plant spacing is a factor influencing the growth of oil palm plants. Plant spacing is done to get an area for plant growth, to avoid a sun and nutrients competition for each oil palm plant, and to make it easier maintenance. This study aimed to see   the growth and production of oil palm at different planting distances. This research was carried out at the Oil Palm smallholder Plantation located in Suko Awinjaya Village, Sekernan District, Muaro Jambi Regeny, 64 kilometers (representing 8×8 m spacing) and 69 kilometers (representing 9×9 m spacing). This research was conducted in March-April 2019. The design of the experiment was carried out as an unformatted trial and the location was porpusively chosen as  there were a uniform plants in that location. Sampling determination of the locations was based on spacing differences e.g.  Planting distance 8 × 8 m (P1), Planting distance 9 × 9 m (P2). The Systemic Sampling method was used in this study. The parameters observed were plant height, stem circumference, weight of fresh fruit bunches (FFB), productivity, light intensity, air temperature, air humidity (%). A measured agronomic each observed parameter was analyzed by Independent t test (significant level of 5%). The result showed that the oil palm plantations with 8x8 m distance planted give a higher growth  and a smaller stem circumference than the 9x9m. While a higher both of Fresh Fruit Bunch Weight and productivity were obtained at a 9x9 m spacing than those at 8x8 m planted distance.

The paper aims to study the position of the optimum oil palm ripeness at the bunch different positions. This information is essential to complete a measurement procedure to detect oil palm fresh fruit bunch (FFB) maturity so that the detection devices can directly measure the optimal mature position as a representative of the entire FFB characteristics. In this study, the oil palm FFB (Elaeis guineensis Jacq. var. tenera) with the various ripeness stages (4 until 22 weeks after anthesis) were collected and divided from three positions, i.e., proximal, central and distal. Moreover, each fruit in each of these positions was subjected to sample preparation to identify water and oil content. The water and oil content were completed based on the oven test method and the Soxhlet extraction technique, respectively. The optimum ripeness position is determined based on the lowest water content and the highest oil content. Based on the analysis, during the process of oil palm maturation occurs a decrease in water content and an increase in oil content. In addition, the average water content of palm fruit varies greatly depending on its position based on the analysis, i.e., proximal (45.38±5.62%), central (35.30±3.34%) and distal (41.98±2.57%). The average oil content of oil palm fruit in the central position is higher oil content (25.10±1.72%) compared to the proximal (10.00±0.77%) and distal position (13.77±1.22%). We suspect that the chemical content differences of palm fruit in various positions are due to the inequality of the respiration rate and ethylene production throughout FFB. In addition, overall it can be concluded that the fruit in the central FFB position has an optimal ripeness level compared to the proximal and distal position. Thus, the measurement position recommended in evaluating palm maturity is at the central position of FFB.

Balancing Efficiency

Balancing efficiency and sustainability of fresh fruit bunches (FFB) production remains a critical issue facing by oil palm (Elaeis guineensis Jacq.) producing countries like Indonesia. To address those issue, we analyze trade-offs of those 2 variables in plantation managed by smallholders and compare the result to the one of the companies. The trade-offs are estimated by dividing the GHG emission to the partial factor productivity (PFP) of FFB production based on data from previous LCA assessment. Our study revealed that current practices implementing by smallholders are economically less efficient and ecologically unsustainable comparing from the FFB production practices implementing by companies. For smallholders, the trade-offs of ecological impact and economic efficiency reached 0.86 kg CO2-eq/kg FFB or 2.6 times from the trade-offs of FFB production by companies (0.33 kg CO2-eq/kg FFB). Several changes in nutrient management such as adjusting the fertilizers rate at smallholders in Sumatera, improving the OER from 0.20 to 0.22 for smallholders and from 0.21 to 0.22 for companies, and applying biochar technology are the most promising practices to minimize the trade-off up to 81%.

Oil palm (Elaeis guineensis Jacq) is an important crop for Indonesia as one of non fuel export commodities. Development, improvement of quality and productivity of oil palm is influenced by a lot of factors, among others are land characteristics. This research was aimed to know the relationship between oil palm productivity and physical land characteristic including soil, slope and the crop age. The results of this research were expected to be useful to improve oil palm productivity and the oil palm plantation development.This research was done within the site of PT. Perkebunan Nusantara VIII at Cimulang, Bogor. In this research, analyzing correlation between productivity of blocks that have homogenous land characteristic with physical land characteristic parameter including soil and slope. Block with homogenous land characteristic was block which 75% or more of it’s area had similar characteristics. These blocks were determined by overlying block map, slope map and soil map. The result show that were 20 homogenous blocks out of all the 38 blocks of the site the PT. Perkebunan Nusantara VIII at Cimulang. Average production was depend on crop age. At study areas, the highest average fresh fruit bunch production obtained from plants 5 years, which was equal to 22.87 tons acre-1 year-1 and the lowest average fresh fruit bunch production obtained from plants 3 years, which was equal to 0.66 tons acre-1 year-1.  Based on soil, the highest average fresh fruit bunch production obtained from the SPT 11 (Typic Eutrudox), which was equal to 12.54 tons/acre/year and the lowest average fresh fruit bunch production obtained from SPT 1 (Oxic Dystropept), which was equal to 9.51 tons/acre/year. Based on slope class, the highest average fresh fruit bunch production obtained from block with slope class B (8-15%), which was equal to 12.54 tons/acre/year, and the lowest average production was equal to 9.98 tons/acre/year from the slope class.
