Abstrak. Penelitian tujuan untuk mengetauhi pengaruh jarak tanam dan konsentrasi pupuk organik NASA, serta interaksi antara keduanya pertumbuhan dan hasil tanaman sawi. Penelitian ini dilaksanakan di Kampung Reje Pudung Kecamatan Terangun Kabupaten Gayo. Pada bulan Januari sampai April 2019. Penelitian ini menggunakan Rancangan acak kelompok (RAK) pola faktorial. Faktor pertama jarak tanam yang terdiri dari 3 taraf yaitu 15 m x10 cm, 15 cm x 15 cm, 15 cm x 25 cm. Sedangkan faktor kedua konsentrasi pupuk organik cair Nasa yang terdiri dari 4 tarap yaitu 0 cc /Liter air, 1 cc / Liter air, 2 cc/Liter air 3 cc/Liter air. Hasil penelitian menunjukkan bahwa perlakuan jarak tanam dan pengaruh nyata terhadap tinggi tanaman umur 16, 40 HTS, diameter batang umur 28 HST, jumlah daun 16,28,40 HST dan berat berangkasan kering tanaman sawi, tetapi tidak berpengaruh nyata terhadap tinggi tanaman umur 28 HST, diameter batang umur 16,40 HST, dan berat berangkasan basah tanaman sawi. Rata rata perlakuan terbaik terdapat pada jarak tanaman 15 cm x 15 cm ( J2), sedangkan perlakuan pupuk organik NASA berpengaruh nyata ter hadap tinggi tanam umur 16,40 HTS, diameter batang umur 16,28,40 HST berat berangkasan basah, berat berangkasan kering tanaman sawi. Dan tidak ber pengaruh nyata ter hadap tinggi tanaman umur 28 HST. Rata rata perlakuan terbaik ter dapat pada pupuk organik Nasa 3 cc / Liter air (P3) Ter dapat Interaksi yang nyata antara perlakuan jarak tanaman dan pupuk organik NASA ter hadap tinggi tanaman umur 16,28,40 HST, batang diameter umur 16,28,40 HST, daun jumlah umur 16,28,40 HST berat berangkasan basah, berat berangkasan kering tanaman sawi, dan tidak interaksi yang nyata ter hadap tinggi tanaman umur 28 HST. Rata-rata per lakuan interaksi ter baik ter dapat pada per lakuan jarak tanam 15 cm x 15 cm dengan konsentrasi pupuk organik Nasa 3 cc/liter air (J2P3) the effect of planting Distance end Concentration of nasa Organic fertilizer on the Growth an Yield Of Plants Mustard (Brassica sinensis L) Abstract. Thisms to determine the effect of plant spacing and concentration of Nasa organic fertilizer, as well as the contraction between the two to the growth and yeield of mustard greens plants. Group (RBD) factorial pattern. The first plant spacing consists of 3 levelsi, nameely 15 cm x 10 cm, 15 cm x 15 cm, 15 cm x 25cm, while the second factor is NASA's liquid organic fertilizer concentration which consists of 4 levels namely 0cc / liter of water, 1 cc / liter of water, 2 cc / liter of water and 3 cc / liter of water. The results showed that plant spacing treatment significantly affected plant height at age 16, 40 DAP, stem diameter at age 28 DAP, number of leaves 16, 28, 40 DAP and the weight of dried bunches of mustard plants, but had no significant effect on plant height at age 28 DAP , stem diameter age 16, 40 HAP and the wet weights of mustard plants. The best average treatmenti was foound ata spacing of 15 cm x 15 cm (J2). While NASA's organic fertilizer treatment significantly affected plant height age 16, 40 DAP, stem diameter age 16, 28, 40 HAP, number of leaves aged 16, 28, 40 DAP, wet wet weight, dry dry weight of mustard plants, and no siignificant effiect to plant height at 28 DAP. the average best treatment is found on NASA organic fertilizer 3 cc / liter of water (P3). Therei was a reali interaction betweeni plant spacing and NASA organic fertilizer on plant height age 16, 40 DAP, stem diameter age 16, 28, 40 DAP, number of leaves age 16, 28, 40 DAP, wet wet weight, dry dry weight of mustard plants , and no significant interaction with plant height.
