Abstract

This research aimed to study the influence of phosphate fertilizer and plant growth regulator applications on the growth and yield of ratoon rice grown on swampland. The research was conducted in September 2016 to January 2017 at the greenhouse of Department of Soil Science, Faculty of Agriculture, Sriwijaya University. Soil characteristics were analyzed in the Laboratory of Chemistry, Biology and Soil Fertility, Department of Soil Science, Faculty of Agriculture, Sriwijaya University. The experiment was arranged in a factorial Completely Randomized Design.  The first factor was the phospate fertilizer dosages, i.e. 150 kg ha-1 (P1), 200 kg ha-1 (P2), 250 kg ha-1 (P3). The second factor was the plant growth regulator treatments, consisting of control (Z0), Cytokinin 20 ppm (Z1), Gibberellin 60 ppm (Z3). The results showed that the application of P fertilizer did not affect the yield and growth of ratoon rice. However, the application of Plant Growth Regulators resulted in a significant effect on the growth and yield of ratoon rice. The application of Plant Growth Regulator of Gibberellin with the dosage of 60 ppm was able to increase the percentage of filled grains (84.93%), decrease the percentage of empty grains (15.07%), increase the weight of 100 grains (3.63 g) and increase the dry weight of  milled grains (7.80 Mg ha-1). It is suggested that the treatment resulted in better plant growth and yield obtained in the current study might be recommended for ratoon cultivation in swampland.

Abstract

Nuryenti, et al. Content of Hara N, P, K on Gawangan and Harvest Road Oil Palm Plantation. JLSO 5(2):219-224. Differences in the location of oil palm plantations cause differences in nutrient content contained in the soil. This study aims to analyze the nutrient content of N, P, K of soil on gawangan and harvest road in PT. Sawit Mas Sejahtera. The method used is a detailed survey method with an observed area of 3 ha. Soil analysis results in nutrient content of N, P, K on harvest road showed higher yield compared to gawangan. N-total value on gawangan 0.11% and 0.16%  harvest road, P-bray value on gawangan 6.15 ppm and 15 ppm harvest road, K-dd value on gawangan 0.10 me/100 g and 0.41 me/100 g harvest road. Soil pH on harvest road and gawangan is a very low pH soil ranging from 3.84 to 4.22. Palm oil production may increase by adding calcification first before the application of N, P, K fertilizer especially on harvest road to improve soil fertility and produce optimal production.

Abstract

Bernas et al. 2012. Bamboo Floated-cultivation Model for Upland Kangkung (Ipomoea reptans Poir.)  in Tidal Lowland Area. JLSO 1(2):177-185. South Sumatra Province has a high potential of swampland for expansion of floating agriculture system. Swampland in Palembang, for instance, can be adapted for floating vegetable cultivation.  The experiments on floating agricultural system have been done by using wasted plastic glass, bamboo for rice and glutinous rice with the application of Hycinth and water Fern compost.  The purpose of this research was to build bamboo rafts which were suitable for growing kangkong (Ipomoea reptans).  Previous rafts which contained water saturated soil for rice growing needed to be adjusted for kankong cultivation which prefer unsaturated soil.  Two bamboo rafts were built using four plastic containers in bottom corners.The first raft was filled with soil plus compost (ratio 1:1) and the other was filled only with swamp soil.  Kankong seeds were planted with the distance of 25 cm by 25 cm.  Data were collected weekly and analysed statistically using t-test.  Results showed that when the rafts were supported by two bamboos, plants were died due to excessive water.  Plants grew well after the rafts were supported by plastic containers.   Composting significantly increased plant height, number of leaves, plants fresh and dried weight.  Plant height treated with compost was 38 cm compared to that without compost treatment which was 28 cm. Fresh plant weight was 149 g/bunch with compost treatment and 25 g/bunch without.  Thus, low fertility of swamp soil only required compost to increase nutrients content for plant growth.This research concluded that plant can be cultivated cheaply and environmentally safe in swampland.  Further experiments such as replacing plastic container in raft construction and growing other vegetables on the raft were proposed.

Abstract

The purpose of this study was to study how the physical properties of peat change due to the conversion of secondary forest into oil palm plantations.  It was done by comparing the three conversion stages of the secondary forest into shrubs and oil palm plantations.  The study was conducted in Ogan Komering Ilir District, South Sumatera Province, about 100 km south of Palembang, Indonesia from August to December 2016.  Data collection was done randomly at all sites, each of five points for field sampling, observation of soil profile and measurement of hydraulic conductivity and water table depth.  The samples were collected at a depth of 0-30 cm, both for undisturbed cores and bulk samples.  The hydraulic conductivity was measured in the field using the auger holes method.  The peat strength was determined by using the hand operated cone penetrometer.  Data analysis was done descriptively and regression correlation test.  The results showed that conversion of secondary forests into oil palm plantations has led to the decline in the quality of some of the physical properties of peat by decreasing total porosity, water table depth, hydraulic conductivity, organic matter content, moisture content and increasing the bulk density and peat strength.
