Abstract

Oil palm (Elaeis guineensis Jacq.) is one of the higher multi-purpose crop in the plantation sector in Indonesia, especially Riau Province. To support the growth and development of oil palm seedlings needed a good planting medium that serves as a place of growth and development of roots and place the plant absorb nutrients and water. One of them is the provision of boiler ash and phosphate as well as utilize the peat soil as a medium. This study aims to determine the effect of boiler ash and rock phosphate on the growth of palm oil (Elaeis guineensis Jacq) in the main nursery. The design used in this research is completely randomized design (CRD) factorial consisting of two factors. The first factor is the provision of boiler ash treatment with 4 levels. The second factor is the natural phosphate treatment with 4 levels and each unit is repeated 3 times. The study states that increased doses of boiler ash and rock phosphate given to plant oil palm seedlings showed no significant effect on plant height increase, in the number of leaves, the increase in diameter tubers, plant dry weight and ratio root crown.   Keywords: Abu Boiler, Phosphate, Oil Palm

Abstract

This researchaims to know the species amountd, total individual, calculate population density (K) and relative density (KR)  soil macrofauna in oil palm plantation (Elais guineensis Jacq) in peatland by giving organic matter in water level is different.This research are conducted by observation, sampling for soil macrofauna of data is determined by purposive random sampling method, and data soil macrofauna results to analyzed statistic descriptive. The results showed that the  amountd species, total individual, population density and relative density of soil macrofauna were higher in water levels of 40-50 cm. The  giving organic matter in the soil water level is different in the first month, giving palm fronds and Mucunna bracteata produces the number of species, the total individual, population density, and density of the soil macrofauna relative higher than that of oil palm empty fruit bunches,while in the third month the  species, the total individual, population density, and density of the soil makorfauna ralatif higher in the provision of oil palm empty fruit bunches and palm fronds.In water levels same produce  the  amountd species, total individual, population density,  and relative density of soil macrofauna higher ground in water levels of 40-50 cm except amountd species in the third month. key words : soil macrofana, water level, organic metter

Abstract

The purpose of this research was to determine the physical properties of acid Dystrudepts in the circle area of palm oil plant applied the organic mulch of Mucuna bracteata. Soil physical analysis carried out in the soil laboratory of Agriculture Faculty, University of Riau, on October 2014 to February 2015. Application of organic mulch Mucuna bracteata. This research was arranged on using Completely Rendomized Design (CDR) nonfactorial that consists of            4 treatments and 4 replications . The treatments consisted of M0 (0 kg/plant), M1 (15 kg/plant), M2 (30 kg/plant) and M3 (45 kg/ plant). Parameters measured were soil moisture, soil temperature, organic matter, bulk density, total of pore space and  infiltration. Research suggests that the application of organic mulch Mucuna bracteata increase soil organic matter and improving soil physical. Keywords : Soil Physical properties, Dystrudepts, Mucuna bracteata

Abstract

One effort to improve chemical properties of Dystrudepts is to use an organic mulch Mucuna bracteata (MB). The study aims to determine the effect of application of organic mulch MB on soil chemical properties and plant root growth of oil palm. The research was conducted in experimental station and the soil laboratory, Faculty of Agriculture, Riau University, Pekanbaru. The research was conducted in September 2014 – February 2015. The research was non factorial experiment that arrangge by Randomized Complete Design (RAL) with treatment control, M1 (15 kg of organic mulch/plant), M2 (30 kg organic mulch/plant), and M3 (45 kg organic mulch/plant). The results showed that application of an organic mulch MB with more increasing dose resulted more increasing of pH value, C-organic, N-total, KTK, KB and root growth.   Keywords: organic mulch, Dystrudepts, Mucuna bracteata

Abstract

This research was aimed to  know biomass production, nitrogen fixation and root nodules by LCC on Dystrudepts. The research was conducted at the greenhouse of Faculty of Agriculture University of  Riau  from December 2013 to Maret 2014.This research was an experimental with 5 treatments (Mucuna pruriens, Pueraria javanica, Calopogonium mucunoides, Centrosema pubescens and Mucuna bracteata) with 4 replications and each  replications consist of 4 plants. Data obtained from this study were analyzed by ANOVA and continued with Duncan’s New Multiple Range Test at 5%. The results showed that LCC panted on Dystrudepts produce different biomass, nitrogen fixation and  also root nodules on Dystrudepts and Mucuna pruriens is better than Calopogonium mucunoides, Pueraria javanica, Centrosema pubescens and Mucuna bracteata.   Key words: LCC, Dystrudepts, Mucuna pruriens.

Abstract

This researh aimed to determine the effect of water level and organic mulch on physical and chemical properties of peatland in palm oil plantation. Research was conducted for four months which is started on November 2014 to February 2015 at palm oil plantation of ​​PT. Teguh Karsa Wana Lestari (TKWL) in Buantan Besar village, sub district Bungaraya, Siak District. By used 8 years old of palm oil plant. This research used Split Plot Design, consist of 2 factors. The first factor is the water level as main plot, were: the level of 40-50 cm water, 60-70 cm water level and 80-90 cm water level. The second factor is giving organic mulch as sub plot, were: without giving organic mulch, giving palm oil empty fruit bunch (POEFB), palm frond and Mucuna Bracteata. Therefore obtained 12 combinations of treatments and 3 replications, so obtained 36 units experiment. Parameters observed were physical and chemical properties. Data were analyzed by Analysis of Variance (ANOVA) and were further tested by Least Significant Diference (LSD) at5 % level. Based on statistical data obtained non significant effects by water level and organic mulch in physical and chemical properties of peatland. The result of single factor by organic mulch obtained significant effects in physical and chemical properties of peatland. The result of single factor by water level  obtained significant effects in peatland water content parameters.   Keywords : Physical and chemical properties, water level, organic mulch in peatland
