Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian persentase naungan terhadap pertumbuhan bibit kopi liberika Tungkal Jambi (Coffea liberica W. Bull Ex Hiern) dan untuk mendapatkan persentase naungan yang dapat meningkatkan pertumbuhan kopi liberika Tungkal Jambi (Coffea liberica W. Bull Ex Hiern). Penelitian dilakukan di Teaching and Research Farm Fakultas Pertanian Universitas Jambi. Waktu pelaksanaan selama tiga bulan dari Maret 2021 sampai Mei 2021. Penelitian ini dilaksanakan dengan menggunakan Rancangan Acak Kelompok (RAK) Satu Faktor yaitu pemberian naungan (N) yang terdiri dari 6 perlakuan yaitu: N0 = Tanpa Naungan, N1 = Persentase Naungan 40%, N2 = Persentase Naungan 50%, N3 = Persentase Naungan 60%, N4 = Persentase Naungan 70%, N5 = Persentase Naungan 80%, dan setiap perlakuan diulang sebanyak 4 kali. Setiap unit terdiri dari 4 tanaman. Variabel yang diamati adalah tinggi tanaman, diameter batang, luas daun total, berat kering tajuk, berat basah akar, berat kering akar, rasio tajuk akar dan intensitas cahaya. Hasil penelitian menunjukkan bahwa pemberian berbagai persentase naungan memberikan pengaruh terhadap terhadap pertumbuhan bibit kopi liberika Tungkal Jambi (Coffea liberica W. Bull Ex Hiern). Persentase naungan 80% memberikan perbedaan yang nyata terhadap variabel pengamatan tinggi tanaman, diameter batang, luas daun total, berat kering tajuk, berat basah akar dan intensitas cahaya yang masuk pada kopi liberika, namun tidak berbeda nyata terhadap berat kering akar dan rasio tajuk akar kopi liberika. Berdasarkan hasil penelitian ini dapat disarankan untuk menggunakan persentase naungan 80% pada pembibitan kopi liberika terutama bagi para penakar bibit kopi liberika. The objective of this research is to know the effect of providing shade percentage on the growth of Jambi Tungkal liberica coffee seedlings (Coffea liberica W. Bull Ex Hiern) and to obtain the percentage of shade that can increase the growth of Jambi Tungkal liberica coffee seeds (Coffea liberica W. Bull Ex Hiern). The research was conducted at the Teaching and Research Farm, Faculty of Agriculture, Jambi University. The implementation time is three months from March 2021 to May 2021. This research was carried out using a One Factor Randomized Block Design (RAK) namely providing shade (N) which consisted of 6 treatments, namely: N0 = No Shade, N1 = 40% Shade Percentage, N2 = 50% Shade Percentage, N3 = 60% Shade Percentage, N4 = 70% Shade Percentage, N5 = 80% Shade Percentage, and each treatment was repeated 4 times. Each unit consists of 4 plants. The variables observed were plant height, stem diameter, total leaf area, crown dry weight, root wet weight, root dry weight, root crown ratio and light intensity. The results showed that the provision of various percentages of shade had an effect on the growth of Jambi Tungkal liberica coffee seedlings (Coffea liberica W. Bull Ex Hiern). The percentage of shade 80% gave a significant difference to the observed variables of plant height, stem diameter, total leaf area, shoot dry weight, root wet weight and light intensity in liberica coffee, but not significantly different to root dry weight and root crown ratio liberica. Based on the results of this study, it can be suggested to use a shade percentage of 80% in liberica coffee nurseries, especially for liberica coffee seed breeders.
