Abstract

The objectives of this study were to determine the effectiveness of LCC planting methods on replanting areal and to determine the best growth of LCC between lining, digging and broadcasting methods. This research was conducted in Ukui sub-district, Pelalawan district, Riau. This research was conducted by experimental method which was arranged in Randomized Complete Block Design (RCBD). The first factor is the method of planting which consists of lining system, digging system and broadcasting system. The second factor is land condition which consists of hilly area, flat area and low area. Each treatment combination with 3 replications. The data of the research were analyzed by analysis of variance at level of 5%. If there is a real difference, then tested by DMRT at 5% confidence level. The results showed that planting system gave the same effect to LCC growth. While the best condition of land for LCC growth is on flat area and low area than hilly area. Keywords : Lining, digging, broadcasting, hilly area, flat area, low area, LCC

Abstract

The study objective was to determine the response of growth and production of oil palm on frond fertilizer application. The duration experiment, from June 2017 to April 2018 at the Educational and Experimental Garden of the Stiper Agriculture Institute, Stiper Edu Agro Tourism (SEAT), Ungaran, Central Java, Indonesia. This study used an experimental method with a completely randomized factorial design. The first factor was the age of plants consisting of 2 levels for 6 years old plants and 12 years old plants. The second factor was the dose of frond fertilizer application with 3 levels of application. As control (5 kg/plant/year NPK fertilizer), 2 kg/plant/year frond fertilizer, 4 kg/plant/year frond fertilizer. The experiment using 7 replications for each combination treatment. The result on vegetative growth of oil palm showing the same effect on control and frond fertilizer applications. However, significant increase of production shown in the frond fertilizer application. The total weight of fresh bunches based on harvest observations in January, February, March and April 2018, the highest at the age of 6 years old oil palm which was given 2.0 kg/plant/year frond fertilizer (63.2 kg FFB/4 months). Oil palm productivity with an application of 2.0 kg/plant/year frond fertilizer showing result of 18.96 tons of FFB/ha/year. Compared this to the productivity of control with gain of 6 tons of FFB/ha/year. The highest average weight of fresh bunch in oil palm age 12 years in 4.0 kg frond fertilizer application, with average weight of fresh bunch was 14 kg. Keywords: oil palm, frond fertilizer, vegetative growth, productivity
