Abstract

The productivity of oil palm plants is influenced by genetic factor planting materials, soil, climate, cultivation and plant maintenance. Nursery is the first step to prepare the prime plant material. In the implementation of the nursery, fertilization is one important maintenance factor and should be done with reference to 4T (Exactly Types, Dosage, Time and Method). Loss of fertilizer is an important thing to be controlled. This research is a conservation action by packing fertilizer in sachet bag and conservation treatment. The research was conducted in August 2016- June 2017 at STIPAP. The study used 2x2 Factorial Design with the first Factor of Broadcast System, Sachet and the second factor was with and without conservation. The best treatment was SK1 Sachet application and conservation increased leaf number 14,44 (6%), girth 18,60 cm (14%) and chlorophyll 63,16 (20%).

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

ABSTRACT White root disease (WRD) is a very harmful disease in rubber planting material preparation. The treatment method for infected budded stump has not been determined; therefore, the infected stump is usually directly eradicated through burning. This research aimed to understand the effect of the sulfuric compound to WRD rate and budded stump growth in polybag nursery. The research was arranged based on Completely Randomized Design (CRD) non-factorial with chemical concentration treatment using four levels i.e. 0 g/l (control), 2 g/l, 4 g/l, 6 g/l, dan 8 g/l that was carried out at Sungei Putih Research Center Greenhouse in Galang, Deli Serdang. The trial result indicated that the submersion of infected budded stump level two into sulfuric solution up to the concentration of 8 g/l for 15 minutes did not decrease WRD rate. The shoots growth showed was not significantly different than without submersion. The submersion method is seemed not proper to treat WRD on the budded stump since it only can be conducted once at the beginning of the stump planting into the polybag. Therefore, research on the effect of sulfur for WRD treatment on the budded stump has to be carried out variously from the dosage as well as application method viewpoint.

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.
