The low annual growth rate of the stipe in oil palm progenies is desirable to increase these crops’ productive and economic life. Recurrent reciprocal selection (R.R.S.) has allowed the development of oil palm populations through several breeding cycles with an increased frequency of favorable alleles associated with traits of interest. The present study evaluated families derived from Deli dura × African dura crosses. For 12 years, the yield, vegetative characteristics, and the amount of oil in seven dura progenies were assessed to estimate, from the information collected, the genetic parameters, heritability, and phenotypic correlations among quantitative genetic traits of high-yielding dwarf progenies. The analysis was carried out using analysis of variance, followed by a comparison of means for all estimated traits. The effect of the progenies was highly significant (p ≤ 0.01) for most traits. The yield values, expressed in fresh fruit bunches (FFB) for the progenies, ranged from 165 to 208 kg per palm per year. The oil-to-bunch ratio (O/B) ranged from 17% to 19%, with an overall average of 18%. One of the essential characteristics in this study was the vertical growth of the stipe. Progenies P6 and P7 were identified as those with the lowest annual increase in height, with values of 0.29 and 0.33 m year−1. The values indicate that these are slow-growing cultivars with a high FFB yield and O/B. The highest heritabilities were found for the vegetative trait height (71.62%) and the number of leaflets (46.64%). The development of dura parents with slow growth characteristics in combination with a high bunch and oil production allows extending the productive life of the crop to more than 35 years, providing added value to obtaining differentiated cultivars of oil palm.

Abstract The objective of this work was to estimate the genetic parameters, correlations, and selection gains for the oil production of interspecific hybrids progenies between American oil palm, of ‘Manicoré’ origin, and oil palm, of ‘La Mé’ origin. Thirty-nine progenies were evaluated from the sixth to the ninth year after planting, for the productivity of fresh fruit bunches (PROD_FFB), oil content in the bunch (OCB), and palm oil productivity (PROD_OP). The genetic parameters and gains from direct (GDS) and indirect (GIS) selection were estimated for PROD_OP. High values of heritability for the CVg/CVe ratio indicated favorable conditions for the selection. With the selection of 20% of the progenies (selection in both sexes), the following estimates were obtained: 11.15% GDS for PROD_OP, 9.1% GIS for OCB, and 8.1% GIS for PROD_FFB. The PROD_OP of the progenies was of 6,175, 6,057, and 5,995 kg ha-1 per year with GDS and GIS for OCB and PROD_FFB, respectively. The restricted selection of the LM2T male genitor offspring resulted in 5.1% estimated GSD and in a mean of 5,800 kg ha-1 per year for PROD_OP. Selection gains for PROD_OP can be achieved immediately through the selection restricted to oil palm male genitors, and, in the medium and long term, through the interspecific reciprocal recurrent selection between American oil palm and oil palm populations.

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.

Physical damage to fruit on oil palm fresh fruit bunches due to harvest and postharvest activities include injured fruit mesocarp, fruit weight loss, and loss in fruit bunches. One of the postharvest handlings that can maintain the physical quality of the fruit is by giving gibberellins (GA3). This research aims to determine the effect of the concentration of gibberellins (GA3) whit application time before harvest on the physical quality of postharvest oil palm fresh fruit bunches. The research was conducted at Afdeling VI Garden Cot Girek PT. Perkebunan Nusantara I and in the Cot Girek Palm Oil Factory laboratory. The time of the research was conducted in June until July 2019. The study used a non factorial randomized block design method with 4 treatment levels (0 mg/l, 50 mg/l, 100 mg/l, and 150 mg/l) with 3 replications. The administration of gibberellins has a significant effect on fruit loss and fruit weight reduction with the best concentration of gibberellins is 50 ppm but does not have a significant effect on pH, moisture content, and fruit free fatty acids.

This study assessed the youths’ involvement in oil palm fruit processing activities in Ondo State, Nigeria. It described the socio-economic characteristics of youths involved in oil palm fruit processing activities, determined their level of involvement, examined their perception and identified constraints associated with their involvement. Multistage sampling procedure was employed to select 120 respondents from the study area. Interview schedule was employed to collect relevant data, which was analysed with SPSS software package. Descriptive statistics were used to summarise the data while inferential statistics were used to draw inference on hypothesis. The results show that majority (63.3%) were male, 95.8% had formal education with a mean age of 27.2 ± 2.7 years. Picking of fresh fruit bunches ( = 2.71), packaging ( = 2.60) and gathering of bunches ( = 2.50) were the major activities youth involved in. Higher percentage (57.9%) of the youth had favourable perception towards involvement in oil palm fruit processing activities. Lack of modern processing facilities ( =3.65) and funds/inadequate credit facilities ( = 3.65) were the prime constraints to their involvement. Number of labour (r = 0.7460; p≤0.01) and income (r = 0.601; p≤0.01) of the respondents were significantly related to youth involvement. The study concluded that youth had moderate involvement in oil palm processing activities. However, agricultural development stakeholders like government should provide adequate and functional credits facilities to these youths to encourage their involvement.

Palm oil is one of the plantation crops that have high economic value and is growing rapidly. The wider the area of oil palm plantations in Indonesia, the more palm oil mills will process palm fresh fruit marks and produce waste from processed palm oil, namely solid waste and liquid waste. Each tonne of fresh fruit bunches (FFB) processed at the plant will potentially leave waste of about 23% empty palm oil, 4% wet decanter solid, 6.5% shell, 13% fiber, and 50% liquid waste. This review will discuss the utilization of palm oil mill liquid waste (LCPKS) which is organic material that still contains many benefits such as nutrients, therefore the application of liquid waste is an effort to recycle some of the nutrients (recycling nutrients) which is followed by harvesting fresh fruit bunches (FFB) from oil palm so that it will reduce the cost of fertilization which is classified as very high for oil palm cultivation. During the processing of oil palm fruit into palm oil in the palm oil industry, the remaining process is obtained in the form of liquid waste. If done properly, the liquid waste of the palm oil industry is considerable potential and can increase the added value of waste itself.Keywords: liquid waste industry, palm oil, utilization

<p>ABSTRAK<br />Produktivitas kelapa sawit rakyat di Provinsi Lampung masih relatif<br />rendah dibanding potensi produktivitas optimal. Berkenaan dengan hal itu,<br />dari bulan Februari sampai dengan September 2012 dilakukan kajian<br />dengan tujuan mengidentifikasi karakteristik agroekologi dan teknis<br />pengelolaan kebun kelapa sawit rakyat yang berpeluang diperbaiki agar<br />produktivitas kebun kelapa sawit rakyat meningkat. Kebun kelapa sawit<br />rakyat yang diidentifikasi dipilih secara acak di tujuh kabupaten di<br />Provinsi Lampung. Pengumpulan data dilakukan melalui survei dan<br />wawancara petani. Rata-rata produksi tandan buah segar (TBS) kebun<br />kelapa sawit rakyat di Lampung masih rendah (15 ton/hektar/tahun).<br />Produksi ini berpeluang ditingkatkan melalui penerapan teknologi yang<br />dapat mengatasi sifat-sifat agroekologi sebagai faktor pembatas<br />pertumbuhan dan produksi kelapa sawit, seperti ketersediaan air, retensi<br />hara, dan bahaya erosi. Teknologi yang dibutuhkan untuk mengatasi<br />kendala tersebut antara lain membangun irigasi suplemen, meningkatkan<br />kemampuan tanah dalam menyimpan air, memperbanyak penggunaan<br />bahan organik dan kapur, serta mengaplikasikan teknologi konservasi<br />tanah dan air. Produktivitas kebun kelapa sawit rakyat akan berpeluang<br />meningkat  seiring  dengan  bertambahnya  umur  tanaman,  serta<br />meningkatnya penggunaan pupuk organik untuk tanaman yang telah<br />menghasilkan (TM) dan pupuk NPK untuk tanaman belum menghasilkan<br />(TBM). Pembinaan petani perlu diintensifkan untuk meningkatkan<br />kesadaran petani akan pentingnya memupuk TBM. Hasil analisis<br />mengindikasikan bahwa pemupukan NPK untuk TBM berkorelasi positif<br />dengan produktivitas kelapa sawit.<br />Kata kunci: Elaeis guineensis Jacq., agroekologi, pengelolaan kebun<br />kelapa sawit rakyat, produktivitas</p><p>ABSTRACT<br />Productivity of smallholder oil palm in Lampung province is still<br />relatively low compared to the potential for optimal productivity. A study<br />was conducted with regard to that, from February to September 2012 to<br />identify the agroecological characteristics and technical management of<br />smallholder oil palm plantations that likely to be improved in order to<br />increase the productivity of oil palm of smallholder. Smallholder<br />plantations studied were randomly selected, each 1 sites in seven districts<br />in Lampung Province and data collection was conducted through surveys<br />and interviews of farmers. Average production of fresh fruit bunches<br />(FFB) of smallholder oil palm plantations in Lampung are still low (15<br />tons/hectare/year). The production is likely to be enhanced through the<br />application of technology that is able to cope with the nature of<br />agroecology as the constraints of growth and production of oil palm,<br />namely the availability of water, nutrient retention, and erosion hazard.<br />The technology needed to overcome the obstacles include supplementing<br />irrigation, increasing the soil's ability to store water, multiplying the use<br />of organic materials and lime, and applying soil and water conservation<br />technologies. Besides that, oil palm productivity of smallholder likely<br />increase, along with the increasing age of the plant, the growing use of<br />organic fertilizer for plants that have produced (TM) and NPK fertilizer<br />for immature plants (TBM). Development of farmers needs to be<br />intensified to increase farmers' awareness of the importance of fertilizing<br />the TBM. The results of the analysis indicated that NPK fertilization for<br />TBM positively correlated with the productivity of oil palm.<br />Keywords: Elaeis guineens</p>

Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palm, primarily the African oil palm Elaeis guineensis. Oil palm is one of agriculture comodity that can increase farmers income, provide raw material on manufacture industry which can create added value.  The expansion of oil palm farming in Indonesia has shifted the use of mineral land to suboptimal land which is currently available in many place in Indonesia. Generally the aim of this research is to anylize the competitiveness sensitivity of oil palm farming. Specifically this research wants to anylize the sensitivity on input-output changing, and to anylize the impact of government policy on input-output when facing fluctuation price. In order to reach the goal of this research we used Policy Anlayisis Matrix (PAM). The result of this research shows that partially the declining of price, declining of output volume and increasing input price PCR value and DRCR < 1, which means that the oil palm farming on suboptimal land has competitivenes, and the absence of government policy on determaining input price nor output price on oil palm farming in at suboptimal land. While simultanously shows that the fluctuation of input and output price causes value of PCR dan DRCR  > 1 with PCR value 1,12 and DRCR value 1,04, means that oil palm farming on suboptimal land at Musi Rawas Regency not feasible and has no competitiveness.  It means that government policy needed to protect input price in oil palm farming on suboptimal land.  Therefore government support and guidence in oil palm farming technology on suboptimal land also needed to increase the production of oil palm farming on suboptimal land.

Objective: To determine potential and water-limited yields in oil palm producing areas in the State of Tabasco, México. Design/Methodology/Approach: The ERIC III v. 3.2 database (IMTA, 2009) was used to select climatological stations with daily precipitation and maximum and minimum temperature records, going back to more than 20 years. The methodology proposed by the FAO and improved by Fischer et al. (2012) was used to estimate the potential yield. The equation reported by Ruiz-Álvarez et al. (2012) was used to estimate the annual water deficit from the climatic water balance. Results: The average potential yield of oil palm with a high level of inputs varies from 35.8 to 40.6 t ha-1 of fresh fruit bunches. The average water-limited yield can vary from 15.6 to 23.5 t ha-1 in plantations of at least 8 years of age, under rainfed conditions. The reduction in the maximum average attainable yield was the result of 19.2-49.5% soil moisture deficits. Study limitations/Implications: In order to determine their impact on potential and water-limited yields, climate change horizons must be included in future studies; this would enable researchers to establish the future theoretical economic profitability of the crop. Findings/Conclusions: The analysis between the yields indicates that —if the gap between the current yields and water-limited yields is closed— output and percentage would be 6.5-14.4 t ha-1 and 72.8-129% higher than the potential yield.

Cultivation of oil palm is inseparable from pests. One of the main pests that attack oil palm plants is  the rat class which can cause  oil palm plantations get a high losses. The aim of this study was to determine the attacktion  intensity of  the bush rat (Rattus sp) in   Oil Palm smallholder at  Suko Awin Jaya Village, Muaro Jambi Regency. The research was carried out from February to April 2021 at the oil palm smallholder specifically  farmer group“Ridho Ilahi”. The experimental design was  unformated trials, and the location was purposively  chosen. The location determination of the sample was based on to  the initial survey that there was found     rats attacktion in this place. Sampling was carried out concurrently at the time  fresh fruit bunches harvesting,   fruit counting in the bunch, counting the number of fruits eaten by rats, counting good fruit (free from rat pest attacks), and weighing the weight of fresh fruit bunches. Parameters observed were the attacktion  level in the land, attacktion  intensity, production per hectare, environmental sanitation conditions. The rats attacktion  rate of  100%, means that all sample  in one stretch of   plantation  have been   attackted by rats, it was indicated by a bite scars on the harvested fresh fruit bunches. The attacktion intensity of the bush rat pest was 23%. The average production was 21.6 tons/hectare/year. The sanitation conditions on the land was partially overgrown with weeds and there were piles of midrib in the area between the certain two path of oil palm tree.
