Description
Salah satu faktor yang mempengaruhi pertumbuhan dan produksi kopi adalah intensitas cahaya. Intensitas cahaya berhubungan dengan jenis naungan yang digunakan. Tujuan penelitian adalah mengevaluasi pengaruh berbagai jenis tanaman penaung terhadap pertumbuhan dan produksi kopi Arabika. Penelitian dilaksanakan di Kebun Percobaan (KP) Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar Sukabumi dari bulan Februari sampai dengan Desember 2011. Rancangan penelitian yang digunakan adalah acak lengkap dengan 6 ulangan. Perlakuan yang diuji adalah jenis pohon penaung, yaitu: (1) ceremai, (2) belimbing wuluh, (3) kayumanis, dan (4) gliricidia. Pengamatan dilakukan terhadap parameter tinggi tanaman, jumlah buku cabang primer, jumlah cabang primer, diameter batang, diameter tajuk, jarak antar cabang, dan persentase tanaman berbuah. Hasil penelitian menunjukkan bahwa gliricidia merupakan jenis tanaman penaung yang cocok bagi pertumbuhan dan persentase pembuahan tanaman kopi Arabika varietas Kartika 1 di KP Pakuwon. Effect of Various of Shading Plant on Growth And Percentage Of Fruiting of Arabica Coffee Variety Kartika 1 ABSTRACT One of many factors that affects to growth and yields of coffee is light intensity. Light intensity will vary with type of shading trees used. The objective of this study was to find out a suitable shading trees for coffea growth and production . The study was carried at The Indonesian Research Institute for Industrial and Beverages Crops (IRIIBC), Sukabumi from Pebruary until December 2011. A randomized complete design with six replications was used in this study. Planting material used in this study was Arabica Coffee (var.

The shading trees of coffee examined were: (1) Otaheite gooseberry, (2) Bilimbi, (3) Cassiavera, and (4) Gliricidia. Observations made were plant height, number of primary branches internodes, primary branch number, stem diameter, canopy diameter, distance between branches, and percentage of fruiting set. Result showed that Gliricidia was the most suitable of shading trees for growth and fruiting set of arabica coffea variety Kartika 1. Keywords :
