Abstract

The most damaging mammalian pests of oil palm plants are rats consisting of house mice (Rattus diardii), rice mice (Rattus argentiventer), and tree rats (Rattus tiomanicus). In controlling rat pest, a census is needed as a guideline for implementing good control. The common census method applied on plantations is 5% of the sample area, but there are obstacles in the implementation for high plants, and rat sporadic attacks. This research was conducted in May - July 2018 at Sei Merah Field with descriptive and correlation techniques. This study aims to evaluate census sample methods, at different attack rates. Another goal is to determine one indication of rat's attacked to represent other indications as a reference for the census method. Observation was made with a census of 100% (whole) trees in the 3 specified areas. Attacked tree category is if there was a damage on the fruit on the tree, the loose fruit (brondolan), and the male flowers on the tree. Then 100% census observation compared to the 50%, 30%, 20%, 10%, and 5% rate samples. The results of the observation showed that the census sample method carried out using a 5% sample was declared effective, because the regression ratio of the results of 5% rate sample (0.90) was not different from the regression of 100% rate sample (1.00) and indications of the tree that attacked by rats on oil palm.

Abstract

This research was conducted on September 2017 – March 2018, in the greenhouse and laboratory of STIPAP Medan. This study used a factorial randomized block design with three repetitions, with total sample was 27 samples. Parameters observed were plant height, stem base diameter, leaf number, leaf area, root number, root length, root dry weight, shoot dry weight, root volume and number of stomata. The data obtained were analyzed statistically by analysis of variance (ANOVA) with Duncan's advanced test of 5%. The results showed that the di erence in the provision of water in the Main Nursery nursery a ected to the growth of oil palm seedlings significantly a ected plant height, canopy dry weight, leaf chlorophyll and root volume except stem diameter, leaf number, leaf area, number of roots, root length, weight dry root and number of stomata. Oil palm is a plant that has shallow roots (root fibers), so it is easy to experience drought stress. Water availability is one of the main limiting factors for the growth and production of oil palm plants. In the vegetative phase lack of water availability can cause damage to plant tissue, while in the generative phase can reduce the production of oil palm plants.

Abstract

Preliminary trail using food poisoning technique obtained output that 0,2 g/L salicylic acid (SA) inhibited growth of leaf fall disease of rubber tree such as Colletotrichum gloeosporioides, Oidium heveae as well as Corynespora cassiicola.The SA inhibited growth of the third leaf fall desease more than 85% in in vitro. The next observation aimed to knowing the effect of SA in growth inhibitionof leaf desease onrubber tree in polybeg. Three level of SA concentration were spraied to the rubber tree young leaf after wo days inoculated with C. gloeosporioides spores. The optimal concentration was used for observation the response of rubber clones PB 260, IRR 122 and IRR 104 to C. gleiosporoides before and after SA spraying. The SA 0,5 g/L decreased the infection intensity of C. gloeosporioides via inducing of the systemic aquired resistance(SAR).There were variation of the infection intensity in the SA treated rubber clones to C. gloeosporioides between 10% to 18%.

Abstract

Oryctes rhinoceros is an important pest of oil palm that cause considerable losses and attack oil palm plants across Indonesia. The damage of beetle attacks can occur in immature plants, as well as the mature plants. The losses caused by these beetles is quite large because the beetles bore into the crown which can e ect to the broken stem. The research was conducted in Afdeling II Kebun Adolina PT. Perusahaan Nusantara IV, Serdang Bedagai Regency, North Sumatra Province on 11 – 27 August 2017. Research method used by traps the beetle using pheromone against the lengthof stick of the trap with four repetitions that are placed in immature plants. The conclusion from this research that the 2 meters of stick ferotrap length traps more Oryctes rhinoceros compared to 4 meters of stick ferotrap length. The large number of pheromones in traps do not a ect the interest of Oryctes rhinoceros.

Abstract

Oil palm nursery is a starting point in greatly determines for the success of planting in the field, while superior seeds are a large capital of the company to achieve high productivity and quality of palm oil. To get a really good, healthy, and uniform seed, strict sorting must be done. The study was conducted at the STIPAP Medan. The study period was 4 months, from April to August 2018. The study used Non Factorial Randomized Block Design (RBD) with 3 treatments and six replications, P1: Standard Fertilizer / Recommended PPKS, P2: Fertilizer Control Release Fertilizer (CRF) 1x application dose of 50 g / seed, P3: Fertilizer Control Release Fertilizer (CRF) 2x application, dose / application 50 g / seed. Parameter testing is compiled on the variance list with a level of 5% and 1% for the whole treatment. The best treatment found in P3 can increase plant height 59.29 cm (18%), stem circumference 15.88 cm (9%), leaf number 12.83 strands (7%), wet weight 188.56 gr (2%) and dry weight 52.45 gr (8%) were compared to the growth of IOPRI/PPKS Medan standard seedlings.

Abstract

This study aims to determine the total microbes, organic matter and soil respiration on application land and without the application of empty fruit bunches. The research was conducted at Begerpang, PT. London Sumatera as the location for taking soil samples, the soil is analyzed in the Soil Biology Laboratory of the Faculty of Agriculture, USU and the Soil and Fertilizer Laboratory, STIP-AP which runs from May to September 2018. The study used Factorial Randomized Block Design, consisting of two factors. Factor 1: sampling area, Factor depth of sampling from ground level. The results showed the average microbial total on the application of oil palm empty fruit bunches 17,05 CFU / ml, organic matter 7,25% and soil respiration 3,18 mg CO2 while on land without the application of oil palm empty bunches the total microbial 3,55 CFU / ml, organic matter 5,07% and soil respiration 2,75 mg CO2. The average total microbes, organic matter and soil respiration is highest at a depth of 0-10 cm. Total microbes are positively correlated with organic matter and soil respiration, the correlation coe cient between total microbes and organic matter is 0.977, between total microbes and soil respiration 0.868 .
