Abstract

This study aims to determine soil physical properties and palm oil productivity in different of water levels (TMA) in peatland. This study conducted in palm oil plantation area in PT. Tabung Haji Indo Plantation Indragiri Hilir Regency, and Laboratory of Soil Science Faculty of Agriculture, University of Riau. This study was carried out started from July until October 2017 by using survey method. Sampling Location conducted by purposive sampling, and sampling point was determined by stratified random sampling. Analysed data used analyse of variance, followed by further test by Duncan’s new multiple range test level of 5%. Parameters observed in physical properties ware bulk density, porosity, water content of maximum occupied capacity, particles size distribution, and palm oil productivity. The result of this study showed that peatland with water levels (20-40) cm (TMA1) showed higher water content of maximum occupied capacity than water levels (>40-60) cm (TMA2), and >60 cm (TMA3). Peat soil with water level TMA2 owned bulk density, the particle size (≤63 µm) higher compared to TMA1 and TMA3. Peat soil with TMA3 showed higher porosity compared to TMA1 and TMA2. Peat soil TMA1 showed higher palm oil productivity compared to TMA2 and TMA3. Palm oil productivity TMA2 and TMA3 showed lower compared to TMA1 is caused by Ganoderma attack.

Abstract

The aims of this study to be determine the soil chemical properties and productivity of oil palm (Elaeis guineensis Jacq.) at different water levels on peatlands. The research was carried out in PT. Tabung Haji Indo Plantation (PT. THIP) Indragiri Hilir and the analys of soil chemical properties were conducted at the Laboratory of Soil Science, Faculty of Agriculture, Universitas Riau, Tampan District, Pekanbaru. This research was held started July to October 2017. This research conducted used survey method. The sampling location in this research are divided into 3 strata in 3 difference blocks and 3 samples that had been determined are named: TMA1 = 20- 40 cm, TMA2 = 41-60 cm and TMA3 => 60 cm carried out experimental used completely randomized design (CRD). There are three times repeatation treatments and 27 samples units in total. The observation data that obtained are analyzed statistically using analysis of variance (ANOVA). The results of variance analysis were continued by Duncan's multiple range test at the 5% level. The parameters of observation carried out include soil chemical properties: pH, C-organic, N-total, P-total, K-total, cation exchange capacity (CEC), saturation of bases (KB) and productivity of oil palm. The results showed that peatland with a water level of > 60 cm had soil pH, organic C, N-total, P-total, K-total, and CEC was higher than the water level of 20-40 cm and 41-60 cm, while KB at a depth of 20-40 cm had a higher KB value than the water level of 41-60 cm and > 60 cm.

Abstract

The research aims to study the response of upland rice on the application of silicates and phosphate fertilizer on Ultisol. The study was conducted in land Ultisol in Pematang Berangan Village, Rokan Hulu Regency, Riau Province. Research in the form of experimental factorial completely randomized design consisting of two factors. The first factor is silicate consists of four levels (0, 50, 75, and 100 kg SiO2/ha), while the second factor that phosphate fertilizer consists of four levels (0, 36, 54, and 72 kg P2O5/ha), each combination was repeated three times. The results showed that application of silicates and phosphates increase the growth and yield of upland rice. The application of 100 kg SiO2 and 36 kg P2O5 per hectare increasing of the percentage of grain pithy and weight of dry grain per square meter, about 21% and 117% respectively compared to without silicates and phosphates.
