Abstract

The research aimed to find out 1) the best growing media for growth and flowering of Dendrobium orchid, 2) the best dosage of mycorrhizal biofertilizer for growth and flowering of Dendrobium orchid, 3) the best combination type of growing media and mycorrhizal biofertilizer for growth and flowering of Dendrobium orchid. The research was conducted at Screen house of Datar Village, Sumbang Subdistrict, Banyumas Regency from May 2017 to November 2017. The research design was using Randomized Block Design (RBD) method with 2 factors and 3 replicates:(1) Growing media with 3 treatment types; wood charcoal, fern (Cyathea contaminans), root of the bird’s net fern (Asplenium nidus), and (2) dosage of mycorrhizal biofertilizer with 3 levels; without mycorrhizal, 10g /plant (20 spores), 20g /plant (40 spores). Data were analyzed by analysis of variance followed by Duncan’s Multiple Range Test (DMRT) at 5% level. The observed variables were the increase of plant height, number of leaves, the increase of leaf area, number of buds, number of roots, number of root length, the appearing of first primordia flower, the first flower blossom, number of flower per stalk, number of flower stalk per plant, length of flower stalk, and percent of mycorrhizal infections. The result of the research showed that root of the bird’s net fern is the best of growing media for variables of the number of leaves and the number of buds for each 5,63 leaves and 1,37buds, as well as the percentage of mycorrhizal infections by 54,44%. Result also showed that the best dosage of mycorrhizal biofertilizer is 10 g/plant for variables of the number of root and the percentage of mycorrhizal infections for each 20,78 roots and 64,44%. The highest number of flowers per stalk was obtained on the combination of growing media using fern (Cyathea contaminans) without mycorrhizal biofertilizer by 8 flowers.Anggrek merupakan tanaman hias yang potensial untuk dibudidayakan, karena mem-punyai nilai ekonomis tinggi. Penelitian ini bertujuan untuk mengetahui jenis media tanam dan dosis mikoria terbaik pada pertumbuhan dan pembungaan anggrek dendrobium serta mem-pelajari interaksi antara pemberian jenis media tanam dan dosis pupuk hayati mikoriza terhadap pertumbuhan, pembungaan anggrek Dendrobium sp. dan infeksi mikoriza. Penelitian dilaksanakan di Screen house Desa Datar, Kecamatan Sumbang, Kabupaten Banyumas mulai Mei hingga November 2017. Rancangan penelitian meng-gunakan rancangan acak kelompok pola faktorial dengan 2 faktor dan 3 ulangan, yaitu (1) media tanam dengan 3 jenis media; arang kayu, pakis (Cyathea contaminans), akar kadaka (Asplenium nidus), dan (2) dosis pupuk hayati mikoriza dengan 3 taraf; tanpa mikoriza, 10 g tanaman-1 (20 spora), 20 g tanaman-1 (40 spora) Hasil penelitian menunjukkan media akar kadaka merupakan media terbaik untuk variabel pertambahan jumlah daun dan jumlah tunas anggrek Dendrobium masing-masing yaitu sebanyak 5,63 helai dan 1,37 tunas, serta persen infeksi mikoriza sebesar 54,44%. Pupuk hayati mikoriza 10 g/tanaman merupakan dosis terbaik untuk variabel pertambahan jumlah akar dan persen infeksi mikoriza anggrek Dendrobium masing-masing sebanyak 20,78 akar dan 64,44%. Jumlah bunga per tangkai tertinggi diperoleh pada kombinasi jenis media tanam pakis dengan tanpa pupuk hayati mikoriza sebanyak 8 kuntum. Kata Kunci : Dendrobium sp., media tanam, pupuk hayati mikoriza, pertumbuhan dan pembungaa

Abstract

Abstract. The decrease in mushroom produc-tivity due to openings at the top of the baglog needs to be balanced with phosphor to increase the mushroom harvest. The research study the interaction effect of opening position plastic baglogs and concentration of phosphor fertilizers to growth and yield of oyster mushroom. The experiment has been done in Mushrooms House, Faculty of Agriculture, Winaya Mukti University, Sumedang with altitude of 850 m above sea level. It was carried out  from  September until December 2015. The experimental design used in this experiment was completely randomized design and treatment design was factorial. The treatment consisted of two factors: the opening position of plastic baglogs and fertilizer concentrations of phosphor fertilizer. Opening position of plastic baglogs consists of a 6 levels that b1 = vertically baglog, the top of baglog opened entirely, b2 = vertically baglog, left side baglog opened at areas 3cm x 1cm, b3 = vertically baglog, left and right side baglog opened at areas 3cm x 1cm, b4 = horizontally baglog, left and right side baglog opened entirely, b5 =  the left side baglog  opened at areas 3cm x 1cm, and b6 = left and right side baglog opened at areas 3cm x 1cm. The concentration of phosphor fertilizer consisted of 3 levels that p0 = 0 g L-1 solution, p1 = 0.25 g L-1 solution, and p2 = 0.50 g L-1 solution. All treatment was replicated 2 times. The results showed that there was interaction between  opening position of plastic baglog and a concentration of phosphor fertilizer to height of mushroom fruiting bodies.Keywords: Baglog, Oyster Mushrooms, Phosphor Sari. Penurunan produktivitas jamur akibat bukaan plastik pada bagian atas baglog perlu diimbangi dengan pemberian fosfor untuk meningkatkan hasil panen jamur tiram. Penelitian bertujuan untuk mempelajari pengaruh interaksi  posisi bukaan plastik baglog dan konsentrasi pupuk fosfor terhadap pertumbuhan dan hasil jamur tiram putih. Percobaan telah dilakukan di Kumbung Jamur Fakultas Pertanian Universitas Winaya Mukti (UNWIM), Kabupaten Sumedang dengan ketinggian tempat 850 m di atas permukaan laut dan dilaksanakan mulai dari bulan  September  sampai bulan Desember 2015. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan rancangan perlakuan adalah faktorial. Perlakuan terdiri dari dua faktor yaitu posisi bukaan plastik  baglog dan konsentrasi pupuk fosfor.  Posisi bukaan plastik baglog  terdiri dari 6 taraf faktor yaitu b1 = baglog diberdirikan, bagian atas baglog dibuka  seluruhnya, b2  = baglog diberdirikan, samping kiri baglog bagian tengahnya dibuka seluas 3cm x 1cm, b3  = baglog diberdirikan, samping kiri dan kanan baglog bagian tengahnya dibuka seluas 3cm x 1cm,  b4  = baglog ditidurkan, samping kiri dan kanan baglog dibuka seluruhnya, b5 = baglog ditidurkan, samping kiri baglog bagian tengahnya dibuka seluas 3cm x 1 cm, dan b6 = baglog ditidurkan, samping kiri dan kanan baglog bagian tengahnya dibuka seluas 3cm x 1 cm  . Konsentrasi pupuk fosfor terdiri dari 3 taraf faktor yaitu p0 = 0 g L-1 Larutan, p1  = 0,25 g L-1 Larutan , dan p2 = 0,50 g L-1 Larutan, sehingga terdiri dari 18 kombinasi perlakuan yang diulang sebanyak 2 kali. Hasil percobaan menunjukkan terjadi interaksi antara posisi bukaan plastik baglog dengan konsentrasi pupuk fosfor terhadap tinggi tubuh buah jamur.Kata kunci : Baglog, Fosfor, Jamur Tiram
