In Africa, oil palm is grown in 25 countries supported by corporate investors. In Uganda, commercial oil palm cultivation began in 2005 in Bugala Islands. Seedlings were imported from countries with established breeding programs. These seedlings were grown in areas with different environmental conditions which have resulted in a number of physiological disorders. The aim of this research was to determine the major physiological disorders in oil palm fruit bunches in Uganda. The study was carried out in the adaptive trials in Kagadi, Bugiri, Buvuma and Masaka Districts and in the different smallholder farmer blocks in Kalangala District. Data was collected on bunch rot, bunch failure and uneven ripening. Sampling was carried out in oil palm plantations above five years of age. Three fields were selected from each unit and three units from each block by the help of the Agricultural Extension Officers (AEOs). Palms were randomly sampled and assessed for presence of bunch rot, bunch failure and uneven ripening symptoms. The incidence was expressed as a percentage of the total number of palms sampled while the severity of bunch rot disease was scored on a scale of 0-4. From the results, the differences in bunch rot and bunch failure in adaptive trials were statistically significant as well as across seasons (P < 0.05). Uneven ripening was not statistically significant and severity of bunch rot in the different farmer blocks in Kalangala was statistically significant (P = 0.03). Uneven ripening was high across smallholder farmer blocks in Kalangala and was statistically significant (P = 0.05) even across seasons (P < 0.05). These results are important for sensitization of farmers on management of oil palm disorders and essential for guiding policy makers and investors as the oil palm industrial sector is being developed in Uganda. This study calls for determination of water deficit at the various ecological zones and its relationship to physiological disorders as a guide for further oil palm estate development.

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.

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.

Basically, oil palm has three types of fruit, namely the dura, pisifera, and tenera varieties. These three varieties have different characteristics, likewise with resulting Crude Palm Oil (CPO) levels. Generally, palm oil contains 500–700 ppm of carotenoid compounds, and the amount is equivalent to 15 times the carotenoids in carrots and 300 times in tomatoes. This is a study of information about the carotenoid composition of three varieties of oil palm fruit and applying the most superior analytical methods to obtain carotenoids from CPO. The purpose of this review is to examine the carotenoid composition of three varieties of oil palm fruit and carotenoid analysis methods presented for consideration as a reference. The method used in this review is the inclusion and exclusion criteria in literary search. The results showed that the carotenoid composition of the three varieties of oil palm in the presence of 11 types of carotene and the highest percentage composition was β-carotene with a content range of 54.39–56.02%. As for the development of new methods for carotenoid analysis from CPO, namely Raman and FT-NIR spectroscopy with the advantages of being environmentally friendly, not using solvents, and fast measurement compared to methods UV-Vis Spectrophotometry, UPLC, and HPLC.

The purpose of this research is to know the influence of compost TKKS and NPK 16:16:16 on the breeding of oil palm (Elaeis guineensis Jacq.) in Main Breeding with Sub Soil Ultisol Media. This research has been conducted in the field of Agriculture Faculty of the Islamic University of Riau. for 4 months, starting from April to August 2017. The design used in this research is Factorial Random Design (RAL) consisting of two factors, the first factor is Giving of empty palm fruit bunch compost (Factor K) consisting of 4 levels ie not giving empty bunches of palm oil (K0), giving compost of oil palm empty bunch 90 gr/plant (K1), 180 gr/plant (K2) and 270 gr/plant (K3), and NPK 16:16:16 Fertilizer (Factor P) consisting of 4 levels ie not giving fertilizer (P0), NPK 16:16:16 15 g/plant (P1), 30 gr/plant (P2), 45 gr/plant (P3) and 60 gr/plant (P4). The parameters observed in this study were the increase of plant height (cm), the increase of the number of stem (strands), the length of the longest stem length (cm), the increase of girth (cm), the number of root root (root) and root length (cm). The result of the research showed that the interaction of TKKS compost and NPK 16:16:16 fertilizer gave a significant effect on the plant height increase, the increase of midrib, the length of the longest bark and the increase of girth. Combination of best treatment on compost TKKS 270 g/plant and NPK 16:16:16 60 g/plant (K3P4) fertilizer. The main effect of TKKS compost and NPK 16:16:16 fertilizer gave a significant effect on all parameters in the range of plant height, the increase of midrib, the length of the longest stem, the increase of girth, the number of root roots and the longest root length. With the best treatment is the compost TKKS 270 g/plant (P3) and fertilizer NPK 16:16:16 60 g/plant (P4).
