Respon Pertumbuhan Bibit Kopi Arabika (Coffea arabica L.) Varietas Ateng Keumala akibat Pemberian Pupuk Organik Cair Buah-buahan dan Dosis Pupuk Fosfor

Abstract

Tujuan penelitian ini untuk mengetahui pengaruh konsentrasi pupuk organik cair dari  buah-buahan dan dosis pupuk fosfor terhadap pertumbuhan bibit kopi arabika varietas Ateng Keumala, serta interaksi antara konsentrasi pupuk organik cair dan dosis pupuk fosfor. Penelitian ini dilaksanakan di Batang Beranun Kecamatan Bandar Bener Meriah dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian Universitas Syiah Kuala Darussalam Banda Aceh pada tanggal 1 Juli sampai 30 September 2018. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola faktorial dengan 2 faktor yaitu pengaruh konsentrasi pupuk organik cair buah-buahan dengan 3 taraf yaitu, Kontrol, 40 ml/L air dan 80 ml/L air. Dosis pupuk fosfat terdiri atas 3 taraf yaitu, 2 g/polibag, 4 g/polibag, dan 6 g/polibag. Hasil penelitian menunjukkan bahwa pupuk organik cair berpengaruh sangat nyata terhadap berat berangkasan basah akar, berpengaruh nyata terhadap tinggi tanaman umur 30, 60, 90 HSPT, panjang akar, berat berangkasan kering tajuk. Berpengaruh tidak nyata pada diameter pangkal batang, berat berangkasan basah tajuk dan berat berangkasan kering akar. Pertumbuhan bibit Kopi Arabika terbaik terdapat pada perlakuan pupuk organik cair konsentrasi 80 ml/L air. Dosis pupuk fosfat berpengaruh sangat nyata terhadap tinggi tanaman umur 60 dan 90 HSPT dan berat berangkasan basah akar, berpengaruh nyata terhadap berat berangkasan basah tajuk. Namun berpengaruh tidak nyata  terhadap tinggi tanaman umur 30 HSPT, diameter pangkal batang, panjang akar, berat berangkasan kering tajuk dan berat berangkasan kering akar. Pertumbuhan bibit Kopi Arabika terbaik terdapat pada perlakuan dosis pupuk fosfat 6 g/polybag. Terdapat interaksi yang tidak nyata antara konsentrasi pupuk organik cair dan dosis pupuk fosfat pada semua parameter.

Response to Growth of Arabika Coffee Seeds with Varieties (Coffea arabica L.) or Keumala by Giving Liquid Organic Fertilizer and Phosphorus Fertilizer Dosage

Abstract. The purpose of this study was to determine the effect of the concentration of liquid organic fertilizer from fruits and phosphorus fertilizer dosage on the growth of Arabica coffee seeds at the Ateng Keumala variety, as well as the interaction between the concentration of liquid organic fertilizer and phosphorus fertilizer dose. This research was carried out in Batang Beranun, Bandar Bener Meriah Subdistrict and Laboratory of Plant Physiology, Faculty of Agriculture, Syiah Kuala Darussalam University, Banda Aceh on July 1 to September 30, 2018. This study used a factorial randomized block design with 2 factors namely the effect of organic fertilizer concentration liquid fruits with 3 levels, namely, Control, 40 ml / L water and 80 ml / L water. The dose of phosphate fertilizer consists of 3 levels, namely, 2 g / polybag, 4 g / polybag, and 6 g / polybag. The results showed that liquid organic fertilizer had a very significant effect on the weight of wet root roots, significantly affected plant age 30, 60, 90 HSPT, root length, canopy dry weight. Not significant effect on stem diameter, canopy wet weight and root dry weight. The best growth of Arabica Coffee seeds is found in the 80 ml / L water concentration of liquid organic fertilizer. The dose of phosphate fertilizer has a very significant effect on plant age 60 and 90 HSPT and the weight of wet rooted roots, has a significant effect on canopy wet weight. However, it did not affect plant height at 30 HSPT, stem diameter, root length, canopy dry weight and root dry weight. The best growth of Arabica Coffee seedlings is found in the treatment of 6 g phosphate fertilizer / poly bag. There was no significant interaction between the concentration of liquid organic fertilizer and phosphate fertilizer dosage on all parameters.
