Interaction Between Oryctes Rhinoceros and Leaves’ Nutrient Content in Oil Palm

A study meant to evaluate the relationship between the presence of Oryctes rhinoceros to the oil palm in relation to the leaves’ nutrient content which is Phosphorus (P) and Potassium (K). Appropriate fertilization is one of the methods that can help to suppress the pests’ presence in the field. In general, insects’ pests are attracted to the plants that are supplied with excess supply of nutrient as it can help them to develop better in future as these nutrient play their roles in aiding through growths and insects’ fecundity. Data on nutrient status were collected were Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Copper (Cu) and Zinc (Zn). These data had been collected twice per month which were at the middle and at the end of each month. Four samples of leaves were taken from four sampling oil palm trees of each treatment. Leaves from ninth or seventeenth fronds were chosen as it is the best most ideal fronds to be used for leaf analysis to identify the nutrient content. The result of this study showed that Phosphorus (P) exerted a strong positive relationship with the presence of Oryctes rhinoceros in the oil palm while Potassium (K) showed a strong negative relationship between the two variables. Thus, developing awareness to the growers to this nutrients-balancing issue would be good for future agriculture in future as it is clear now that balanced nutrition is primordial to ensure availability of nutrients uptake by plants.

The availability of nutrients in seagrass beds can act as growth limiting factors. Absorption of nutrients in the water column is carried out by the leaves while the absorption of nutrients from the sediment is carried out by the roots but does not rule out the transport of nutrients by the roots will also arrive at the leaves of the seagrass. If the nutrient requirement is not met properly, then the growth will be disrupted. Like the difference in distribution and density of seagrass itself. Nutrient concentrations in waters vary. Nitrate and phosphate levels in the waters are strongly influenced by sources of organic material from outside/land (allochthonous) or from the water itself (autocthonous). This research was conducted with the aim of nothing: to determine the relationship between nutrient content (nitrate and phosphate) in sediment to seagrass cover in Teluk Awur and Pantai Blebak, JeparaData collection of seagrass and sediment was carried out on March 2018 in the waters of Teluk Awur and Blebak Beach, Kabupaten Jepara. Type identification, density, and coverage are carried out at the research location. Nitrate and phosphate analysis in sediments is carried out in Laboratorium Pengujian dan Peralatan. Based on the results of research that has been carried out, it can be concluded that there is a very strong positive relationship between nutrients and seagrass closure in the two research locations, each of which is 0.955 (91.1%) in Teluk Awur waters and 0.962 (92.6%) in Blebak Beach.Ketersediaan nutrien di perairan padang lamun dapat berperan sebagai faktor pembatas pertumbuhan. Penyerapan nutrien pada lamun pada kolom air dilakukan oleh daun sedangkan penyerapan nutrien dari sedimen dilakukan oleh akar namun tidak menutup kemungkinan pengangkutan nutrien oleh akar juga akan sampai pada bagian daun. Jika kebutuhan nutrien tidak terpenuhi dengan baik, maka pertumbuhannya mengalami gangguan. Seperti perbedaan sebaran dan kepadatan lamun itu sendiri. Konsentrasi nutrien di perairan bervariasi. Kadar nitrat dan fosfat di perairan sangat dipengaruhi oleh sumber bahan organik yang berasal dari luar/ daratan (allochthonous) maupun dari dalam perairan itu sendiri (autocthonous). Penelitian ini dilakukan dengan tujuan: untuk mengetahui hubungan antara kandungan nutrien (nitrat dan fosfat) pada sedimen terhadap tutupan lamun di Teluk Awur dan Pantai Blebak, Jepara. Identifikasi jenis, kepadatan dan penutupan dilakukan pada lokasi penelitian. Analisa nitrat dan fosfat dalam sedimen dilakukan di Laboratorium Pengujian dan Peralatan. Berdasarkan hasil penelitian yang telah dilakukan dapat di ambil kesimpulan bahwa terdapat hubungan sangat kuat positif antara nutrien dengan penutupan lamun pada dua lokasi penelitian, nilainya masing-masing sebesar 0,955 (91,1%) di Perairan Teluk Awur dan 0,962 (92,6%) di Pantai Blebak.

Abstract Oil palm produces the most consumed vegetable oil in the world. In addition to being economically viable and having multiple uses, the crop has a strong ecological appeal, given its high level of carbon sequestration, its low environmental impact, and a low mechanization level in the harvest process, generating income and financial sustainability for the inhabitants of that biome. However, despite the large areas suitable for cultivation in harmony with the forest in Brazil, oil palm production has been limited by a disease known as fatal Yellowing (FY). In 30 years of research to determine the causal agent of this disease, many epidemiology studies with insects and plant pathogens have been performed, but there is no consensus on its cause. Abiotic factors have also started to be considered a possible cause of these symptoms. Therefore, to clarify the relationship of this disease to environmental variables, we studied the nutritional status of the plant, the soil class and fertility, the climatic variables and attempted to verify the set of proteins and their isoforms expressed in diseased palms showing FY symptoms and healthy palms. FY occurred under constant rain and in clay soils; consequently, the roots of these palm trees suffered anoxia, which caused nutritional problems and the accumulation of stress-related proteins. Under these conditions, the usually observed symptom was yellowing, which can lead to the death of the plant, giving the disease its name. In other words, the symptomatic picture is not associated with only a biotic cause. Thus, a pedological survey of the area, planting in soils not subject to waterlogging or with good drainage conditions, and the correct maintenance of soil fertility and plant nutrition may certainly contribute to the management of and reduction in fatal yellowing without the use of agrochemicals.

Reproductive Activities

The using of palm oil waste had not been optimal lately. It could be seen in oil empty fruit bunches (EFB). It was placed along the oil palm plantations. The condition was not only the trigger of air pollution but also could invite rhinoceros beetle pests (Oryctes rhinoceros) to lay their eggs and carry out reproductive activities due to availability organic matter of the trees. Oil palm plants required large amounts of macro nutrients, especially potassium. However, the potassium nutrient was found in EFB was too slow available because of its relatively long breakdown. That was the reason why it was needed a method of using EFB waste into a capable of high use value product, environmentally friendly, and could give a lot of benefits to oil palm farmers. The purpose of this study was to determine the availability of nutrient content in EFB composting by the using of symbiont bacteria from larvae O. rhinoceros. The research was experimentally conducted a factorial randomized block design (RBD) with 2 factors, namely the type of bacteria and the time of decomposition. The composting stage was carried out by coarsely chopping the EFB then 75 ml of bacterial culture was applied to 1 kg of EFB. Analysis, results indicated C/N ratio (35.56% and 36.97%) and high K content (1.64% and 1.48%). The EFB composting method is achievable in 6 weeks with activators of Bacillus stratosphericus and Bacillus siamensis.

Faktor kedua (B) adalah dosis pupuk, yaitu 1) 500 g Urea, 200 g SP 36, 500 g KCl, 1000 g Kiserit, 2) 500 g Urea, 100 g SP36, 500 g KCl, 750 g Kiserit, 3) 1500 g Urea, 750 g SP36, 1375 g KCl, 1250 g Kiserit, 4) 500 g Urea, 200 g SP36, 500 g KCl, 1750 g Kiserit, 5) 250 g Urea, 100 g SP36, 250 KCl, 500 g Kiserit dan 6) 750 g Urea, 300 g SP36, 750 KCl, 1500 g Kiserit. Analisis kandungan unsur hara N, P, K, dan Mg menggunakan daun nomor sembilan dan tanah diambil pada kedalaman 30 cm secara komposit, masing-masing sebanyak 32 contoh daun dan tanah sebelum pemupukan dan 24 contoh daun dan tanah setelah pemupukan. Hasil penelitian menunjukkan bahwa sebelum pemupukan kandungan unsur hara N dan P pada lahan penelitian dalam taraf defisiensi, K pada taraf defisiensi hingga optimum, dan Mg pada taraf optimum. Setelah pemupukan, kandungan unsur hara N pada sebagian besar lahan masih tetap defisiensi. Kalium pada sebagian besar lahan dan Mg pada semua lahan penelitian pada taraf optimum. Sebelum pemupukan, kandungan unsur hara K dalam jaringan daun delapan varietas kelapa sawit dalam taraf defisiensi, P pada taraf defisiensi hingga berlebihan dan Mg pada taraf optimum. Setelah pemupukan, kandungan unsur hara N pada sebagian besar varietas masih pada taraf defisiensi, P pada sebagian besar varietas berlebihan serta K dan Mg pada semua varietas pada taraf optimum. Hasil penelitian ini mengindikasikan bahwa respons tanaman kelapa sawit terhadap pemupukan berbeda menurut varietas. Tingkat kemasaman (pH) tanah tergolong sangat rendah atau tanah bersifat sangat masam, sehingga dilakukan pengapuran menggunakan dolomit sebelum pemupukan. Setelah pengapuran terjadi peningkatan pH tanah, tetapi masih tergolong rendah, atau tanah masih bersifat sangat masam. Oleh karena itu, pengapuran perlu dilakukan di lokasi penelitian.Kata kunci : Status hara, kelapa sawit, analisa tanah, analisa daun, defisiensi hara. Response of N, P, K and Mg Fertilization to Nutrients Contents in Soil and Leaf Young Oil Palm ABSTRACT The research was conducted in order to determine the nutrients content of N, P, K, and Mg in the soil and leaf tissue of young oil palm. The study was conducted in 2014 for one year at the Sitiung Experimental Garden, Darmasraya regency, West Sumatra Province. The study was using a randomized block design with two factors. The first factor (A) were eight superior varieties with age two years-old, namely DMP, DMK, PPKS-Dumpy, PPKS-LTC, PPKS-SMB, PPKS-540, TS1 and TS3. The second factor is fertilizer dosages 1) 500 g Urea, 200 g SP 36, 500 g KCl, 1000 g Kiserit, 2) 500 g Urea, 100 g SP36, 500 g KCl, 750 g Kiserit, 3) 1500 g Urea, 750 g SP36, 1375 g KCl, 1250 g Kiserit, 4) 500 g Urea, 200 g SP36, 500 g KCl, 1750 g Kiserit, 5) 250 g Urea, 100 g SP36, 250 KCl, 500 g Kiserit dan 6) 750 g Urea, 300 g SP36, 750 KCl, 1500 g Kiserit. For the analysis of the nutrient content of N, P, K and Mg, leaf samples were taken on leaf number nine and soil samples were taken at a depth of 30 cm in the composite method, 32 leaf and soil samples before fertilization and 24 leaf samples soil. The results showed that before fertilization the nutrient content of N and P in the soil in deficiency level, K on the deficiency to optimum levels, and Mg at an optimum level. After fertilization, the nutrient content of N in the almost all of the area is still deficient. Potassium at most area and Mg in all area of research at the optimum level. Before fertilization, the nutrient content of K in the leaf tissue of eight varieties of oil palm in the deficiency level, P deficiency to excessive level and Mg at the optimum level. After fertilization, the nutrient content of N in most varieties are still at the level of deficiency, P on most varieties in the excessive level as well as, K and Mg in all varieties at optimum level. Results of this study indicated that the response of oil palm to fertilization differs according to varieties. The level of soil acidity (pH) is very low or the soil is very acidic, therefore liming using dolomite were done before fertilization. After liming increased soil pH, but is still relatively low, or the soil is still very acidic. Therefore, liming in the area need to be done again.Keywords : Nutrien status, oil palm, soil analysis, leaf analysis, nutrient content.

Heart Disease Risk

Purpose: Modifications to the amount and type of fat in the diet are recommended as strategies to help reduce heart disease risk. Individuals can choose from a variety of margarines and oils to alter their intakes of different types of fats, and nutrient content claims on product labels (e.g., ‘low in saturated fat’) can help them quickly identify healthful products. However, margarines and oils vary in price. Methods: To examine the relationship between the price and amounts of saturated and trans fats in margarines and oils, and the relationship between price and the presence of nutrient content claims, price and label information were recorded for margarines (n=229) and oils (n=342) sold in the major supermarkets within the Greater Toronto Area. Results: Linear regression analysis revealed a negative relationship between the price and amounts of saturated fat and trans fats in margarines, but not in oils. Margarines with a nutrient content claim were significantly more expensive than were those without a claim. Conclusions: The findings for margarines are of particular concern for lower income groups for whom budgetary constraints result in the purchase of lower priced foods, and also raise important questions about the usefulness of nutrient content claims in guiding food selections.

ABSTRACT The assessment of the nutritional status of plants by leaf diagnosis such as the Diagnosis and Recommendation Integrated System (DRIS) has stood out among traditional methods of interpreting the results of plant tissue analysis. For coconut, nutritional monitoring through foliar analysis has been pointed as an efficient method for fertilizer recommendation, and the results have been traditionally interpreted using the critical level of sufficiency ranges criteria. The aim of this study was to evaluate the nutritional status and establish nutritional standards for the cultivation of hybrid coconut in the municipality of Moju, Pará, using DRIS. The leaf analysis and productivity results of 134 observations for the period 2001-2011 were used to form the database. The most common deficiencies found were lack of K, and possibly excess of Mg. The order of nutrient limitation was K> P> Ca> Fe> N> O> B> Zn> Cu> Mn> Mg. Ca, Fe and K nutrients are more likely to positively respond to fertilization, since Mg, Cu and Mn were diagnosed as having the greatest likelihood of negative response to fertilization. It was also found that N and P are elements that are in the best nutritional balance condition. Regression equations for the relationship between nutrient content in hybrid coconut leaves and its DRIS indexes were adjusted, which allowed establishing nutrient reference values based on DRIS.

The Relationship

To ensure good fertilization, it is necessary to know the optimum nutrient levels for each crop. The most common method for obtaining this information for almond trees is to perform a foliar analysis coupled with the use of interpretive tools such as the traditional range of normality. However, currently, there are other, more sophisticated methods such as the DRIS (Diagnosis and Recommendation Integrated System) and the CND (Compositional Nutrient Diagnosis) which take into account the relationship between nutrients. However, little information is available with respect to these methods in the case of almond trees. In the present work, 288 samples of three contrasting varieties of almond were analyzed—Ferraduel, Ferragnes, and Garrigues (Prunus dulcis, Mill.)—corresponding to bi-weekly sampling between the months of May and September. Leaf analysis data, run with different mathematical and statistical models, lead to knowledge of the optimum period for harvesting samples and the determination of the ranges of normality and norms of DRIS and CND for the Ferraduel, Ferragnes, and Garrigues varieties. Data gained from the leaf nutrient content reported that the best season to harvest and interpret leaf samples was July. In addition, Ferraduel and Ferragnes had higher N, P, and K (2.22, 0.14, and 1.04 mg Kg−1 dw, respectively) than Garrigues (2.00, 0.09. 0.67 mg Kg−1 dw). The norms obtained with the leaf mineral data showed similar values between the Ferraduel and Ferragnes varieties but different values for Garrigues variety. Therefore, Garriges had the highest N/P, N/K, P/K, and P × Mg norms in the DRIS method and the highest VN and VCa norms in the CND method.
