Abstract

Potato production in the highlands is decreasing, therefore it is necessary to increase the yield. This research aims to obtain the interaction between doses of KCl and compost on the growth and yield of potato variety Nadia. The Nadia variety is one of the potato which is tolerate to high temperature and medium land. The research conducted on February until May 2016 in Klino, Bojonegoro, 750 m asl. The research method was using randomized block design that consist with two factors; organic and inorganic fertilization. There are two levels of compost fertilization: 10 ton ha-1 (K1), 20 ton ha-1 (K2) and KCl fertilizer consist of four levels; 100 kg KCl ha-1 (P0), 150 kg KCl ha-1 (P1), 200 kg KCl ha-1 (P2), 250 kg KCl ha-1 (P4). There were eight combinations with four replication. The results showed that there were interaction between the dose of KCl and compost on the parameters: number of leaves, number of stems, height of plant, leaf area, total content of chlorophyll, total number of tubers per plant, weight of tuber per plant, weight tuber per plot, and total harvest. The results showed combination of doses compost 20 ton ha-1 and dosage of KCl 150 kg ha-1 had the optimum result of total yield potato.

Abstract

Produksi kentang di dataran tinggi mengalami penurunan, oleh karena itu perlu upaya untuk meningkatkannya. Tujuan penelitian adalah untuk mengetahui interaksi pemberian kombinasi kompos dan pupuk KCl dalam peningkatan pertumbuhan dan hasil tanaman kentang varietas Nadia. Penelitian dilaksanakan pada bulan Februari-Mei 2016, di Desa Klino, Bojonegoro, dengan ketinggian 750 mdpl. Penelitian menggunaan metode Rancangan Acak Kelompok faktorial dengan 2 faktor yakni kompos yang terdiri dari 2 taraf: 10 ton ha-1 (K1), 20 ton ha-1 (K2) dan pupuk KCl yang terdiri dari 4 taraf: 100 kg KCl ha-1 (P0), 150 kg KCl ha-1 (P1), 200 kg KCl ha-1 (P2), 250 kg KCl ha-1 (P4). Terdapat 8 kombinasi perlakuan dan diulang empat kali. Hasil penelitian menunjukkan terjadi interaksi antara dosis pupuk KCl dan dosis kompos pada jumlah daun, jumlah batang, tinggi tanaman, luas daun, total klorofil jumlah umbi per tanaman, bobot umbi per tanaman, bobot umbi per petak, bobot umbi panen total. Kombinasi perlakuan kompos 10 ton ha-1 dengan dosis pupuk KCl  250 kg ha-1 menghasilkan rerata yang baik di dalam beberapa perlakuan, sementara itu perlakuan kompos 20 ton ha-1 menghasil-kan rerata yang baik dengan dosis KCl 150 kg ha-1.
