Abstract

The rubber plant (Hevea brasiliensis) comes from Brazil. The first rubber tree grew only in South America. Rubber plantations in Indonesia were introduced in 1864, since Hofland established a rubber plantation company in Tanah Panunukan and Ciasem, West Java. Attacks caused by Pestalotiopsis sp. showed brown spots on rubber leaves and a clear boundary between the spots and the healthy leaves. Infected leaves fall prematurely. Generally, those that are heavily attacked are rubber plants that have produced and are not maintained. The aim of the study was to determine the resistance level of introduced clones (PB 217, PB 260, PB 330, PB 340, RRIC 100, IRR 220 and GT 1) to leaf fall disease, namely Pestalotiopsis sp. The research was conducted at the Plant Protection Laboratory of the Sungai Putih Research Institute, using a non-factorial Completely Randomized Design (CRD). The observation result showed that clones PB 217 and GT 1 had the highest attack intensity after 8 days of inoculation namely 89.96% and 89.96%. The lowest attack intensity was found on clone IRR 220 namely 81.64%.

Abstract

In terms of felling the old palms, there are two techniques for oil palm replanting: conventional and underplanting. The conventional method involves felling all of the old palms at once. Under the underplanting technique, on the other hand, the old palms are felled in stages, and the new palms are planted among the remaining old palms. The purpose of this study was to compare the performance of immature oil palms when replanting old palms using conventional and underplanting techniques. The research was conducted in Kebun Rambutan, PT Perkebunan Nusantara III. In comparison to the conventional technique, immature oil palms underplanting required more insertion plants, displayed etiolation symptoms, and had a lower average bunch weight. When using underplanting techniques for oil palm replanting, it is necessary to be disciplined in the application of Best Agronomic Practices in all stages of plant maintenance.

Abstract

The establishment of oil palm plantations is starting from nursery which criteria has been standardized by the seeds produced. Nitrogen is one of the essential nutrients which determine the growth of oil palm (Elaeis guinensis Jacq) at the main nursery. Nitrogen has many sources which are produced from synthetics or natural sources, but on the other side, the pricing of fertilizers was increased any time and then must find an alternative which one is more effective and efficient. The effects of few nitrogen sources to the growth of oil palm in the main nursery is the objective of this research. The experiment was non factorial in a randomized complete block design comparing between N1 (urea Fertilizer), N2 (ZA Fertilizer), N3 (liquid organic fertilizer 60 ml/liter H2O had been extracted from Azolla microphylla), N4 (Azolla microphylla green manure 50 g/polybag) and N5 (Azolla microphylla composted 50 g/polybag) with five replications. The research showed that the height of oil palm in the nursery was not significantly affected by five nitrogen sources 2 and 4 weeks after treatment but significantly on 6, 8, 10 and 12 weeks, the higher plant found at N4 on12 weeks after treatment. Five Nitrogen sources were used not significantly affected amounts of leaves on 2 and 4 weeks but significantly affected on 6, 8, 10 and 12 weeks after applications. In the 12th week applications showed the most leaves on N3 but not significantly different from N4. Circumference of the stem after 2, 4, 6, 8 and 12 weeks after applications were not affected by five nitrogen sources but weight of the roots on fresh and dry conditions were affected by the treatment on 12th weeks which was N5 showed the highest but not different with N3 and N4; longs of the roots was not affected by the treatment. Composted, green manure as good as liquid organic fertilizer from Azolla microphylla had effects on amounts of leaves, height of plant, fresh and dry root weight. Azolla microphylla has the potential to be used as a source of nitrogen fertilizer on fertilizing oil palm at the main nursery.

Abstract

This study was conducted to determine the effect of application of coconut shell biochar on planting media on the growth and uptake of leaf and soil nutrients in oil palm main nurseries. To get good and healthy seeds, soil conditioner is also needed to increase land productivity. One of the soil improvement materials is biochar. This research was conducted in the STIPAP Medan experimental garden. This research was conducted for 6 months. Starting in August 2020 - February 2021. This study used a Factorial Randomized Block Design (RAK) method consisting of 9 treatments with 4 replications, so the total sample was 36 seedlings. Parameters observed were seedling height, stem diameter, number of leaves, shoot dry weight, root dry weight and nutrient N content in leaves and soil. The data obtained were analyzed statistically by analysis of variance (ANOVA) with the F test. The results of this study indicate that the application of coconut shell biochar and compound fertilizer in oil palm nurseries can use the best combination dose of 1.8 kg of biochar and 75% compound fertilizer of the dose. The standard gave several significant and very significant effects on stem height, stem diameter, number of leaves, shoot dry weight and root dry weight. And the interaction of coconut shell biochar treatment and compound fertilizer did not significantly affect all observation parameters.

Banana hump contains water, iron, phosphorus, calcium, carbohydrates, calories and protein, which are potential as organic fertilizers. Application of banana weevil fertilizer is expected to increase the carrying capacity of the soil for the availability of organic matter and nutrients. The purpose of this study was to determine the best concentration or dose of organic liquid fertilizer for banana weevil on the vegetative growth of oil palm (Elaeis guineensis Jacq.) seedlings in the Main Nursery. Based on this statement, this research was compiled with the object of oil palm in the Main Nursery. This research was conducted in the Nursery Practice Garden area at STIP-AP Medan. Soil analysis was carried out at the Soil Laboratory of the Agricultural Technology Research Institute (BPTP) of North Sumatra. The time of the study was carried out for 8 months, from January 2021 - August 2021. This study used a Randomized Block Design (RAK) with 2 factors, namely Factor (1) Liquid Organic Fertilizer Banana Cobs and Factor (2) Compound Fertilizer (NPK) 16:16 :16. The treatment was repeated 3 times, with the number of samples being 2 plants so that the sample population was 54 plants. Parameters observed were seedling height, stem circumference, number of leaves, leaf width, root wet weight, shoot wet weight, shoot dry weight, root dry weight, total nitrogen nutrient content and C-organic nutrient content. The data obtained were analyzed statistically by analysis of variance (ANOVA) with 5% and 1% significant difference tests. The results showed that the treatment of banana weevil liquid organic fertilizer and compound fertilizer had no significant effect on the observed parameters. However, the biomass formed was significantly affected as indicated by the weight parameter. The availability of total nitrogen and C-organic nutrients in Ultisol soil showed a very low classification with total nitrogen values of 0.07 – 0.09% and C-organic values of 0.22 – 0.54%.

Abstract

Oil palm plantations are often damaged by pests, especially the horn beetle (Oryctes rhinoceros) The damage caused can potentially suffer losses, either directly or indirectly. This study aims to determine the effectiveness and intensity of the horn beetle catch obtained by combining fruit traps with various colors of lights in the Immature Plants (TBM) area, the lights used are 18 watt emergency lights. This study used a non- factorial Randomized Block Design (RAK) research method with five levels of treatment, namely: P0 (white light + pineapple), P1 (yellow light + pineapple), P2 (blue light + pineapple), P3 (green light + pineapple). . light + pineapple). light + pineapple). , P4 (red light + pineapple) with four replications to obtain 20 treatment samples. The parameter observed was the number of beetles (O. rhinoceros) trapped. The results of this study showed that P1 was significantly different from treatment P2, P3 and P4 but not significantly different from treatment P0, in general, treatment P1 was the most effective treatment with the acquisition of horn beetles trapped as many as 146 tails. This is because yellow light has a color spectrum length of 560-590 nm which best corresponds to the wavelength of the color spectrum that is acceptable to insects, which is 300-650 nm. In addition, yellow light is more unified and gives a more dominant light reflection in the dark.
