<![CDATA[Abstrak. Talas (Colocasia esculenta L. Schott var. Antiquorum) merupakan tanaman pangan yang dapat dikonsumsi oleh masyarakat. Kompos adalah bahan organikk yang dapat memperbaiki sifat fisika, biologi dan kimia tanah. Pupuk KCl dapat membantu dalam pembesaran umbi. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian dosis kompos dan pupuk KCl serta interaksi keduanya terhadap pertumbuhan dan hasil tanaman talas. Penelitian ini dilakukan di Kebun Percobaan II dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian Universitas Syiah Kuala Darussalam Banda Aceh, yang dilaksanakan pada bulan Maret sampai Agustus 2018. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok Pola Faktorial 3 x 3 dengan 3 ulangan. Adapun faktor yang diteliti adalah dosis kompos dengan 3 taraf yaitu 20, 30 dan 40 ton ha-1 dan dosis pupuk KCl dengan 3 taraf yaitu 200, 300, dan 400 kg ha-1. Parameter yang diteliti yaitu tinggi tanaman dan jumlah daun pada umur 2, 4, 6, 8, 10, dan 12 MST, diameter batang pada umur 12 MST, bobot berangkasan basah, bobot berangkasan kering, bobot umbi basah, jumlah umbi dan diameter umbi. Data yang diperoleh dianalisis dengan menggunakan uji F, dilanjutkan dengan uji BNT pada taraf 5%. Hasil penelitian menunjukkan bahwa dosis kompos berpengaruh nyata terhadap jumlah daun tanaman talas pada umur 2 dan 10 MST, bobot umbi segar, dan jumlah umbi tanaman talas. Pertumbuhan dan hasil tanaman talas terbaik dijumpai pada dosis kompos 40 ton ha-1. Dosis pupuk KCl berpengaruh nyata terhadap tinggi tanaman talas umur 2 MST, jumlah daun tanaman talas umur 4 MST, bobot berangkasan basah, bobot umbi basah dan jumlah umbi tanaman talas,. Pertumbuhan tanaman talas terbaik dijumpai pada dosis pupuk KCl 300 kg ha-1 dan hasil tanaman talas terbaik dijumpai pada pada dosis pupuk KCl 400 kg ha-1.The Effect Of Compost and KCl fertilizer on the Growth and Yield of Taro Plants (Colocasia esculenta L. Schott var. Antiquorum) Abstract. Talas (Colocasia esculenta L. Schott var. Antiquorum) is a food crop that can be used by the community. KCl fertilizer can help in enlarging tubers. The purpose of this study was to determine the effect of fertilizer and KCl fertilizers and interactions on growth and yield of taro plants. This research was conducted at Experimental Garden II and Laboratory of Plant Physiology, Faculty of Agriculture, Syiah Kuala Darussalam University, Banda Aceh, which was held from March to August 2018. The design used in this study was a Factorial 3 x 3 Randomized Group Design with 3 replications. The factors examined were compost doses with 3 levels, namely 20, 30 and 40 tons ha-1 and KCl fertilizer dosages with 3 levels, namely 200, 300, and 400 kg ha-1. The parameters studied were plant height and number of leaves at 2, 4, 6, 8, 10, and 12 MST, stem diameter at age 12 MST, wet weighted weight, dry weighted weight, wet tuber weight, number of tubers and tuber diameter. The data obtained were analyzed using the F test, followed by the LSD test at the level of 5%. The results showed that compost dosage was as significant as the number of leaves of taro plants at age 2 and 10 MST, weight of fresh bulbs, and the number of taro tubers. Growth and yield of taro plants at a temperature level of 40 tons ha-1. The results showed that the dose of KCl fertilizer significantly affected the height of taro plants aged 2 MST, the number of leaves of taro plants aged 4 MST, wet weighted weight, weight of tubers and the number of taro tubers, and not even on plant heights of 4, 6 8, 10, and 12 MST, number of leaves aged 2, 6, 8, 10 and 12 MST, stem diameter, dry weight, and tuber diameter of taro plants. The best growth of taro plants when the fertilizer dose of KCl 300 kg ha-1 fertilizer and the results of the best taro plants found at the time of heating KCl 400 kg ha-1 fertilizer.The Effect Of Compost and KCl fertilizer on the Growth and Yield of Taro Plants (Colocasia esculenta L.
