Abstract

A research about effect of soil managment and organic mulch application on soil physical properties of psamment and conr production was conducted in Korong Muaro, Nagari Sunur Kecamatan Nan Sabaris Kabupaten Padang Pariaman, as well as in soil laboratory, Agriculture Faculty, Andalas University Padang.  This research was done from April – October 2009.  The objective of the research was to identify interaction effect between soil cultivation and organic mulch application on chemical properties of psamment and production of sweet corn.  This research was designed in two factors: 3 x 4 with three replications. The first factor was soil cultivation which consisted of 3 levels (Po = No-till, P1 = Minimum tillage, P2 = Conventional till).  The second factor was organic mulch application, which consisted of four levels: Z = without mulch addition, T = Titonia for 8 ton DW/ha, K = Chromolaena for 8 ton DW/ha, J = straw 8 ton DW/ha. The result showed that soil cultivation combined with rice straw mulch application could increase N, P, K elements in soil.  Soil N content increased from 0,17 % to  0,28 %, avail-P from 52,57 ppm to 88,60 ppm, and K-exch from 0,64 me/100g to 2,35 me/100g, however, minimum tillage gave the highest yield which was 7,68 ton weight  of corn seeds + the stalk /hektar, and rice straw mulch showed the highest among the organic mulch applied, which was 8,85 ton/ha.Keywords: Soil cultivation, organic mulch, psamment, sweet corn

Abstract

A research aiming to improve soil aggregate stability of Ultisol in terms of creating sustainable agriculture and environmental development was conducted by applying fresh organic matter (OM)  into soil.  Three types of  OM sources used were Titonia diversifolia, Chromolaena odorata, dan Gliricidia sepium.   This research was conducted in Ultisol Limau Manis Sumbar having annual rainfall > 5000 mm, in 2008.   The fresh OM used was cut, mixed with soil up to 20 cm depth, and then incubated for approximately one month before corn seeds were planted.  Soil was sampled before being treated with OM and then after harvesting corn (4 moths after applying OM).  Soil OM content as well as soil aggregate stability (AS) and several other soil physical properties wer analysed in laboratory.  The results showed that soil OM content and AS increased after one planting period.  Besides that, soil physical properties were also improved.  As soil physical properties became better, corn production was also higher at plot with than without OM application.  Among 3 species of OM added, Tithonia diversifolia gave highest corn biomass.  Level of land slope (0-8% dan 15-30%) did not show significant difference either for biomass or for soil OM content and soil AS.Key Words: marginal soil, green manure, soil aggregate stability, soil organic matter

Abstract

Changes of Soil Properties on Various Ages of Rubber Trees in Dhamasraya, West Sumatra, Indonesia (S Yasin, Adrinal, Junaidi, E Wahyudi, S Herlena and Darmawan): Although rubber has been planted in Indonesia from Holland era, but there is little information about the effect of rubber plantation on the rate of land degradation in Indonesia.  In order to examine the effect of rubber tree (Hevea brasiliansis) ages on land degradation status, a series experiment was done in Dhamasraya district as the main contributor of natural rubber in West Sumatra, Indonesia. Study site divide  into forest (A), crab grass (B), and rubber plantation with ages ranged from 1 (C), 5 (D), 10 (E), 15 (F) and 20 (G) years were selected as study sites and soil samples had been taken from each site, where forest soil  was used as a control. The result proved that the age of rubber tree has strongly affected physical and chemical properties of soil. Organic carbon and total nitrogen content decreased from 3.02%, 2.66%, 1.96%, in site A, B and C, and then increased to 2.33% and 2.49% in site D and E, respectively. This result was opposed with bulk density (BD) value of each site. The highest BD found in site C (1.26 g cm-3), followed by site D, E, B and A with 1.24, 1.14, 1.12 and 0.88 g cm-3, respectively. The similar pattern was also found for selected chemical properties of soil. Soil pH, available phosphorous, exchangeable base cations, cation exchange capacity and base saturation was likely to decrease from 1 to 10 years old plantation and then increased close the natural condition (reflected by forest soil) at 20 years old rubber tree. Since most of plantation was conversed from natural forest, this phenomenon might be because of contribution of organic matter from original condition and addition of fertilizer at the beginning of plantation establishment.

Abstract

Increased use of N fertilizer may substantially increase of nitrate nitrogen (NO3-N) leaching, which potentially pollutes groundwater.  Leaching behaviour of nitrogen (N) was observed in the paddy field of forage rice cultivation. Two kinds of animal manure, cattle manure (CM) and poultry manure (PM) at 5 levels of N application (0, 70, 140, 210, 280 kg N ha-1) as the organic N sources, and without any chemical fertilizers. “Tachisuzuka” forage rice variety was conducted in the experimental plot. Porous ceramic cups were installed in triplicate of each treatment at 45 cm depth to collect the percolation water samples during the cultivation rice periods. The concentration of total N, NH4-N, NO2-N and NO3-N of water (surface and percolation) and soil sample solution were analysed using a Hach DR/2800 spectrophotometer. Result showed that NO3-N leaching was higher than NH4-N in the percolation water during the cultivation of forage rice periods. The highest NO3-N leaching was found in 280 kg N ha-1 (6.3 mg L-1), that it was indicated on the polluted levels. The highest of biomass production was in N280 (16.22 t ha-1) and nearly similar result in N140, N210 and N280. It was concluded that the best application of N-fertilizer in 140 kg N ha-1 because it greatly enhanced N-fertilizer efficiency, and decreased steadily of NO3-N concentration leaching in the environment of the groundwater.Keywords: Ammonium (NH4-N), Forage rice, N behavior, Nitrate (NO3-N), N leaching[How to Cite: Gusmini, K Nishimura, Adrinal, and T Itani. 2013.

Abstract: The earthquake that occurred on 30 September 2009 had an impact on patterns of use of agricultural land and human settlements. Many agricultural lands are turned into residential land, especially the city of Padang. The purpose of this research ; (1). To see patterns and changes in the use of agricultural land in the city of Padang in the aftermath of the 2009 Padang earthquake; and (2) To see the population distribution pattern after the earthquake in Padang City. The method used is spatial and temporal analysis of changes in land use and population distribution before the earthquake and after the earthquake. The results of the study indicate that there has been a change in land use in the City of Padang from 2008-2012. Upland land that is widely used for agricultural business has decreased by 6%. Furthermore, there has been a change in land use in the city of Padang from 20012-2018. The decrease occurred on forest land by 38% and paddy fields by 41%. This decrease occurred due to the conversion of land into settlements which increased to 188%. In 2012, there was a decrease in population, especially in the districts of South Padang, North Padang, West Padang, East Padang and Bungus Teluk Kabung. In other Districts there was an increase, especially those that led eastward. Shifting land cover and the population of the city of Padang affect the Padang City Spatial Pattern.

Abstract

The soil physical properties are one of the components of soil fertility that function as a place for roots to penetrate. Different types of land uses affect the soil physical properties, especially on the availability of water and soil aeration which indirectly affects the availability of nutrients in the soil. Research on the soil physical properties of ex-gold mining, oil palm plantations and forests was carried out on Ultisol located in Tebing Tinggi Village, Dharmasraya Regency from April until October 2021. The objective of this study was to obtain the comparison of soil physics properties in ex-gold mining land with oil palm and forest land on Ultisol. The method on this study was a survey with purposive sampling on three different land uses (ex- gold mining land, oil palm land and forest) at a depth of 0-20 cm and 20-40 cm and it was replicated 3 times. The observed parameters were soil texture, organic matter, volume weight, soil pore space, soil water content, permeability, and soil aggregate stability. Based on soil analysis in the laboratory, it was obtained that the physical conditions of the soil in three different land uses, i.e the physical condition of the oil palm land and forest were better than the ex-gold mining land. The soil texture on ex-gold mining land was classified on sandy clay loam and sandy loam with a very low organic matter content (0,20-1,72 %) if compared with oil palm and forest land. The volume weight in each land use was relatively high with the total soil pore space was low except in oil palm land depths of 0-20 cm, which is 69,93 % vol (moderate). Permeability was slow to moderate with the soil aggregate stability classified as unstable to steady. Soil water content was relatively low except in forest land depths of 20-40 cm which very high criteria (33,93 %).

Abstract

The process of physical and chemical properties of the former gold mining soil which is caused by the transformation of different land conditions in natural rice fields, reclaimed rice fields, and mine fields. This study aims to determine the differences in the characteristics of the former gold mining soil in natural rice fields, reclaimed rice fields and mining fields in Sijunjung Regency. There were three sampling locations with three sample points each and the samples were analyzed physically and chemically. Results of this study showed that natural paddy soil has optimal conditions for the growth of rice plants followed by reclaimed lowland soil and the worst was in mining paddy soil based on soil physical and chemical properties. The difference in soil physical properties in the form of natural paddy soil texture was smoother compared to land conditions in reclaimed rice fields and mining rice fields. This was due to intensive inundation processes, which created a plough tread layer, low volume weight accompanied by a moderate total pore space. The difference in chemical properties was in the stable pH of natural paddy soil due to inundation and high organic carbon accompanied by rice reclamation and very low organic carbon in mining soils, which would affect the growth of rice plant.

Abstract

Penggerek buah kopi (PBKo) Hypothenemus hampei Ferr. adalah salah satu hama utama yang menyerang tanaman kopi Arabika di seluruh dunia termasuk Indonesia. Secara umum, Hypothenemus hampei dapat menyerang berbagai jenis kopi, tetapi kopi Arabika (Coffea arabica) cenderung lebih rentan terhadap serangan ini dibandingkan dengan kopi Robusta (Coffea canephora). Di Indonesia, jenis kopi yang banyak ditanam adalah kopi Arabika dan kopi Robusta. Kopi Arabika lebih banyak ditanam di dataran tinggi, sementara kopi Robusta lebih banyak ditanam di dataran rendah. Menarik untuk mengetahui kelimpahan populasi PBKo dan tingkat kerusakan pada kopi arabika di dataran tinggi. Penelitian ini bertujuan untuk mengetahui kelimpahan populasi dan tingkat kerusakan PBKo pada kopi arabika di dataran tinggi. Pengamatan dilakukan di perkebunan kopi rakyat di Kabupaten Kerinci dan Laboratorium Bioekologi Serangga Departemen Proteksi Tanaman, Fakultas Pertanian Universitas Andalas. Hasil penelitian menunjukkan kerusakan PBKo tertinggi terdapat di Desa Sungai Renah (1242 mdpl), Kecamatan Kayu Aro Barat (1242 mdpl) yakni 64,32% dan kerusakan terendah juga terdapat di Desa N1, Kecamatan Kayu Aro Barat yaitu 8,04% (1654 mdpl). Hal tersebut menunjukkan tingkat kerusakan PBKo berkurang dengan meningkatnya ketinggian lokasi. The coffee berry borer (CBB) Hypothenemus hampei Ferr. is one of the main pests that attacks Arabica coffee plants worldwide, including in Indonesia. Generally, Hypothenemus hampei can attack various types of coffee, but Arabica coffee (Coffea arabica) tends to be more susceptible to this pest compared to Robusta coffee (Coffea canephora). In Indonesia, the most commonly cultivated types of coffee are Arabica and Robusta. Arabica coffee is mainly grown in highland areas, while Robusta coffee is grown in lowland areas. It is interesting to know the population abundance and level of damage caused by CBB on Arabica coffee in highland areas. This study aims to determine the population abundance and level of damage caused by CBB on Arabica coffee in highland areas. Observations were conducted in smallholder coffee plantations in Kerinci District and the Insect Bioecology Laboratory of the Department of Plant Protection, Faculty of Agriculture, Andalas University. The results showed that the highest CBB damage was found in Sungai Renah Village (1242 mdpl), Kayu Aro Barat Sub-district (1242 mdpl), with a damage level of 64.32%, while the lowest damage was found in N1 Village, Kayu Aro Barat Sub-district, with a damage level of 8.04% (1654 masl). This indicates that the level of CBB damage decreases with increasing altitude.
