Abstract

The Sequence of Horizons of Paddy Soils in a Toposequence of Latosol on Volcanic Parent Materials in the Bogor – Jakarta AreaABSTRACT. The sequence of horizons of paddy soils is different from non paddy cultivated. The aim of the research were: (1) to study the sequence of horizons of paddy soils in a toposequence of Latosol on Volcanic materials in the Bogor – Jakarta Area; (2) to study the sequence of paddy cultivated intensity to sequence of horizons. Twelve pedons of different altitude (90 – 650 m above sea level) and different paddy cultivated intensity (0/year, 1/year, 2/year) were investigated sequence of horizons in the field. The result of the research showed that the horizons sequence, on non paddy cultivated soils consist of: tillage layers and the original soil layers. On 1x paddy/year consist of: plow pan layer, and iron/manganese/nodule Mn illuviation layer. On 2x paddy /year consist of: tillage layer of surface reduction, plow pan layer, Fe/Mn illuviation layer, and reduce subsurface layer.

Abstract

Eksplorasi fungi mikoriza arbuskula (FMA) dilakukan dengan kultur trapping menggunakan jagung sebagai tanaman inang dan beberapa media pembawa (pasir, biochar, zeolit). Sampel tanah yang digunakan berasal dari rizosfer berbagai umur kelapa sawit (1, 5, dan 10 tahun) dari PT. Nafasindo Aceh Singkil. Jumlah spora FMA terbanyak dijumpai pada rizosfer kelapa sawit umur  10 tahun (33,94) yang berbeda nyata dengan umur 1 tahun (14,94) dan tidak berbeda nyata dengan 5 tahun (21,88), sedangkan berbagai media tidak menunjukkan pengaruh nyata terhadap jumlah spora. Terdapat dua genus FMA  yang ditemukan di perkebunan kelapa sawit PT. Nafasindo Kabupaten Aceh Singkil, yaitu Glomus (enam spesies) dan Acaulospora (satu spesies), Glomus merupakan spesies yang dominan. Persentase kolonisasi FMA tidak nyata dipengaruhi oleh umur kelapa sawit dan dan media pembawa pada kultur trapping. Kolonisasi FMA kelapa sawit berumur 1 tahun, 5 tahun, dan 10 tahun tergolong rendah . Seperti halnya umur tanaman, kolonisasi FMA pada berbagai media pembawa tergolong rendah.Exploration of Arbuscular Mycorrhizal Fungi on Histosol at Oil Palm Plantation Of PT. Nafasindo Aceh Singkil District with Trapping CultureExploration of Arbuskular Mychoriza Fungi (AMF) by trapping culture used maize as host plant and some carrier mediums (sand, biochar, zeolite). The soil samples used were derived from the various age rhizosphere of oil palm (1, 5, and 10 years) from PT. Nafasindo Aceh Singkil. The results showed that highest number of FMA spores were found in the 10-year-old palm oil rhizosphere (33.94) which was significantly different from the age of 1 year (14.94) and was not significantly different from 5 years (21.88), while the media showed no significant effect on Number of spores. There were two genera of FMA found in oil palm plantation PT. Nafasindo of Aceh Singkil Regency, namely Glomus (six species) and Acaulospora (one species), Glomus is the dominant genus. The percentage of AMF colonization was not significantly affected by the age of oil palm and carrier media in trapping culture. AMF colonization of oil palm aged 1 year, 5 years, and 10 years was low. As like the age, FMA colonization of various carrier media was low.

Abstract

(The Pedological Features of Paddy Soils from a Toposequence on Volcanic Parent Materials in the Bogor – Jakarta Area)ABSTRACT. The pedological feature of paddy soils are different from the non paddy cultivated. The aim of the research were: to study the pedofeatures of paddy soils in a toposequence on volcanic materials in the Bogor – Jakarta area; to study the influence of paddy cultivated intensity of pedofeatures. Twelve pedons of different altitude (90 – 650 m above see level) and different paddy cultivated intensity (0/year, 1/year, 2/year) were investigated, each horizons were sampled for laboratory analysis to study the pedofeatures. The result of the research showed that on non paddy cultivated, pedofeature observed at B horizon is indicating rock weathering. On 1x paddy, at tillage layer nodules and hypocoating were found. On 2x paddy, at plow plan layer clay infilling dense complete was found.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian jenis mikoriza arbuskular spesifik lokal dan kompos serta interaksinya terhadap pertumbuhan dan hasil tanaman jagung pada tanah marginal Ultisol. Penelitian ini berlangsung dari bulan Juni  hingga Oktober 2016, di Rumah Kasa Fakultas Pertanian Universitas Syiah Kuala. Penelitian ini menggunakan Rancangan Acak Kelompok pola faktorial dengan sembilan kombinasi perlakuan dan tiga ulangan, sehingga diperoleh 27 satuan percobaan. Faktor yang diteliti yaitu pemberian jenis mikoriza arbuskular (FMA) yang terdiri dari tiga taraf yaitu: tanpa FMA, Glomus sp. dan Acoulospora sp. sedangkan dosis kompos dengan tiga taraf  yaitu: tanpa kompos, 25 g pot-1,50 g pot-1. Peubah yang diamati dalam penelitian ini jumlah biji per tongkol, berat biji kering per tongkol, berat 100 butir biji kering, dan hasil per hektar. Hasil penelitian menunjukkan bahwa perlakuan baik pemberian jenis mikoriza arbuskular (FMA) dan dosis kompos tidak berpengaruh nyata terhadap jumlah biji per tongkol, berat biji kering per tongkol, berat 100 butir biji kering dan hasil per hektar. Terdapat interaksi yang sangat nyata antara perlakuan pemberian jenis FMA dengan dosis kompos terhadap hasil per hektar serta berpengaruh nyata terhadap berat biji kering per tongkol. Efffect Of Specific Local Arbuscular Mycorrhizas Fungi and Compost Towards Corn (Zea mays L.) On Marginal Land UltisolThe aim of this research was to obtain information about the effect of local and compost specification arbuscular mycorrhizal fungi distribution and the relation towards the growth and result of corn crops on the ultisol marginal land. This research was conducted at Greenhouse of Agriculture Faculty Syiah Kuala University, from June to October 2016. This research used factorial pattern of Cluster Random Plan with nine combinations of treatment and three repetition, thus, 27 attempt of experimentation was obtained. The factors which were inspected in this research are the distribution of arbuscular mycorrhizal fungi which consist of three categories; without arbuscular mycorrhizal fungi, Glomus sp., and Acoulospora sp. while the dosage of compost in three categories; without compost, 25 g pot, 50 g pot. The variables which are observed in this research are the number of corn kernels, the weight of corn kernels per corncob, the weight of 100 dried seeds and the yields of corn crop per hectare. The result of the research conclude that the distribution of abuscular mycorrhiza fungi and the dose of compost  this treatment did not have real effect on the height of the number of corn kernels per cob, the weight of dried seeds per corncob, the weight of 100 dried seeds, and the yields of corn crop per hectare. There are relation between the distribution of AMF treatment and the dosage of the compost to the length the yields of the corn crop per hectare, and also have a real effect on weight of dried seeds per corncob

Abstract

Abstrak: Untuk mengantisipasi menurunnya luas panen dan produksi jagung di Aceh serta untuk tercapainya swasembada jagung nasional di tahun 2017 pemanfaatan lahan-lahan sub-optimal seperti Ultisol dapat dijadikan alternatif. Namun penanganan khusus perlu dilakukan untuk mengatasi permasalahan-permasalahan yang dapat menghambat pertumbuhan tanaman. Dewasa ini, keinginan yang kuat terhadap pertanian berkelanjutan telah mendorong peningkatan pemanfaatan mikrobia tanah indigenus dan aplikasi bahan organik ke tanah. Penelitian ini bertujuan untuk mengetahui pengaruh fungi mikoriza arbuskula spesifik lokal dan kompos terhadap pertumbuhan jagung pada tanah sub-optimal Ultisol. Rancangan yang digunakan adalah rancangan acak kelompok (RAK) faktorial 3 x 3 dengan 3 ulangan. Faktor yang diuji adalah jenis fungi mikoriza arbuskula (kontrol, Glomus sp. dan Acoulospora sp), dosis kompos (0, 25, dan 50 g pot-1). Peubah yang diamati dalam penelitian ini adalah tinggi tanaman dan jumlah daun pada umur 15, 30, dan 45 hari setelah tanam (HST). Hasil analisis ragam menunjukkan bahwa tidak terjadi pengaruh yang nyata baik secara tunggal maupun interaksi antara pemberian mikoriza asbuskula spesifik lokal dan kompos terhadap tinggi tanaman dan jumlah daun 15, 30 dan 45 hari setelah tanam (HST) pada Ultisol. Abstract: To anticipate the decline in harvested area and production of maize in Aceh as well as to achieve national self-sufficiency in maize in 2017 the use of sub-optimal land as Ultisols can be used as an alternative. However, special care needs to be done to address issues that can inhibit plant growth. Today, a strong desire to sustainable agriculture has prompted increased use of soil microbial indigenus and application of organic material to the soil. This study aims to determine the effect of arbuscular mycorrhizal fungi (AMF) specific local and compost on the growth of maize in sub-optimal soil Ultisols. The design used was a randomized block design (RBD) factorial 3 x 3 with three replications. Factors to be examined is the type of AMF (control, Glomus sp., and Acoulospora sp.), the dose of compost (0, 25, and 50 g pot-1). The parameters observed in this study were plant height and number of leaves at 15, 30, and 45 days after planting (DAP). The results showed that there was no significant effect either singly or interaction between local specific of mycorrhizal asbuscular and compost application on plant height and number of leaves at 15, 30 and 45 DAP.
