Abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh jarak tanam dan varietas serta intraksi antara kedua faktor tersebut terhadap pertumbuhan dan hasil tanaman kacang tanah. Penelitian ini dilaksanakan di Desa Gumpang Pekan, Kecamatan Putri Betung. Kabupaten Gayo Lues dan Laboratorium Dasar kampus PSDKU Gayo Lues Universitas Syiah Kuala, dimulai dari bulan Januari sampai April 2020. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) pola faktorial 4 x 2 dengan 3 ulangan. Faktor yang diteliti yaitu jarak tanam terdiri dari 4 taraf J1= 20 cm x 25 cm , J2= 30 cm x 20 cm, J3= 35 cm x 20 cm, dan J4= 40 cm x 20 cm, dan varietas yang terdiri 2 taraf yaitu, varietas lokal, dan varietas Unggul. Hasil penelitian menunjukkan bahwa, perlakuan jarak tanam berpengaruh tidak nyata terhadap pertumbuhan dan hasil tanaman kacang tanah, akan tetapi tinggi tanaman cenderung tertinggi pada perlakuan (30 cm x 20 cm), jumlah cabang cenderung lebih banyak pada perlakuan (35 cm x 20 cm), berat polong, jumlah polong bernas, jumlah polong hampa, berat biji, berat biji kering/tanaman, dan berat 100 biji kering cenderung terbaik pada perlakuan ( 40 cm x 20 cm), berat plot netto dan potensi hasil cenderung terbaik dijumpai pada perlakuan (20 cm x 25 cm). Perlakuan varietas berpengaruh sangat nyata terhadap tinggi tanaman umur 15, 30 HST, jumlah cabang umur 15, 30 HST, berat polong per tanaman, dan berpengaruh nyata terhadap berat 100 biji kering, akan tetapi berpengaruh tidak nyata terhadap tinggi tanaman umur 45 HST, jumlah cabang umur 45 HST, jumlah polong bernas pertanaman, jumlah polong hampa per tanaman, berat biji per tanaman, berat per plot netto dan potensi hasil tanaman kacang tanah. Interaksi antara jarak tanam dengan varietas berpengaruh tidak nyata terhadap pertumbuhan dan hasil tanaman kacang tanah.

The Influence of Varieties and Spacing on Growth and Yield of Peanut (Arachis hypogaea L.)
Abstract. This study aims to determine the effect of spacing and varieties and the interaction between these two factors on the growth and yield of peanut plants. This research conducted in Gumpang Pekan Village, Putri Betung District. Gayo Lues Regency and Basic Laboratory of the Gayo Lues PSDKU campus, Syiah Kuala University, starting from January to April 2020. The research design used was a factorial randomized block design (RBD) 4 x 2 with 3 replications. The factors studied were spacing consisting of 4 levels J1= 20 cm x 25 cm, J2= 30 cm x 20 cm, J3= 35 cm x 20 cm, and J4= 40 cm x 20 cm, and varieties consisting of 2 levels, namely, local varieties and high yielding varieties. The results showed that spacing did not have a significant effect on the growth and yield of peanut plants, but the plant height tended to be the highest in treatment (30 cm x 20 cm), the number of branches tended to be more in the treatment (35 cm x 20 cm), pod weight, number of well-contained pods, number of empty pods, seed weight, dry seed / plant weight, and 100 dry seeds weight tended to be the best in the treatment (40 cm x 20 cm), net plot weight and yield potential tended to be the best in treatment (20 cm x 25 cm). varieties had a very significant effect on plant height at 15, 30 DAS, the number of branches aged 15, 30 DAS, pod weight per plant, and had a significant effect on the weight of 100 dry seeds, but had no significant effect on plant height at 45 DAS, the number of aged branches 45 DAS, number of well-pithed pods per plant, number of empty pods per plant, seed weight per plant, weight per net plot and yield potential of peanut. The interaction between spacing and varieties had no significant effect on the growth and yield of peanut.
