Respon Pertumbuhan Bibit Kopi Arabika (Coffea arabica L.) terhadap Pemberian Bahan Organik di Kebun Kayumas

Abstract

Pertumbuhan tanaman kopi Arabika (Coffea arabica L.) sangat dipengaruhi oleh tersedianya unsur hara makro dan mikro, salah satunya bisa didapatkan dari bahan organik. Penelitian ini bertujuan untuk mengukur dan mengidentifikasi respon pertumbuhan bibit kopi Arabika (Coffea arabica L.) terhadap pemberian bahan – bahan organik. Rancangan percobaan penelitian dilakukan dengan percobaan rancangan acak kelompok (RAK) yang memiliki 4 perlakuan dan 3 ulangan atau kelompok. Perlakukan tersebut terdiri dari K: kontrol dengan tanah top soil; P: tanah top soil dan pupuk kendang (1:1); V: tanah top soil dan vermicompost (1:1); dan B: tanah top soil dan biochar (1:1). Perlakuan pemberian bahan organik berpengaruh nyata terhadap terhadap parameter pertambahan tinggi tanaman, jumlah daun, dan pertambahan diameter batang tanaman, akan tetapi tidak berpengaruh nyata terhadap pertambahan jumlah daun. Pemberian vermicompost memberikan hasil rata – rata tertinggi pada parameter pertambahan tinggi tanaman (0,48 cm) dan pertambahan diameter batang (0,10 mm). Pada parameter jumlah daun perlakuan P memberikan hasil rata – rata tertinggi (2,63 helai). Pemberian vermicompost menyebabkan bibit terbaik dibandingkan pemberian pupuk kandang dan biochar.

Plant of arabica coffee (Coffea arabica L.) growth is also greatly influenced by the availability of macro and micro nutrients, one of which can be obtained from organic materials. This research aims to measure and identify the growth response of arabica coffee seedlings (Coffea arabica L.) to the provision of organic materials. The research experimental design was carried out using a randomized block design experiment which had 4 treatments and 3 replications or groups. The treatments consisted of K: control with top soil; P: top soil and manure (1:1); V: top soil and vermicompost (1:1); and B: top soil and biochar (1:1). The treatment of providing organic material had a significant effect on the parameters of increasing plant height, number of leaves, and increasing plant stem diameter, but had no significant effect on increasing the number of leaves. Application of vermicompost gave the highest average results in the parameters of increasing plant height (0,48 cm) and increasing stem diameter (0,10 mm). In terms of number of leaves, P treatment gave the highest average yield (2,63 pieces). Providing vermicompost produces better seeds compared to providing manure and biochar.
