Effect of Plant Spacing and NPK Fertilizer Application on Plant Growth and Yield of Soybean(Glycine max L. Merril) of Kaba VarietyThis study aim was to determine the effect of plant spacing and NPK fertilizer application on thegrowth and yield of soybean of Kaba variety. The experiment was conducted in the field of theUPTD Balai Pengembangan Benih Palawija (BPBP), Plumbon Sub district, Cirebon District, WestJava from April to July 2014. The experimental method used was an experimental method withRandomized Block Design (RAK) with factorial arrangement of two treatment factors that wasrepeated three times. The first factor was the plant spacing consisted of three levels of 40x10, 40x15and 40x20 cm of plant spacing, while the second factor was the dose of NPK fertilizer whichconsisted of four levels of 200, 250, 300 and 350 kg/ha. Result showed that there was interactionbetween plant spacing and dose of NPK fertilizer to the average of leaf area index of soybean Kabavariety at the age of 21 days after planting. The treatment of Phonska NPK fertilizer in the dose of350 kg/ha gave the best soybean production of 1.44 kg/plot or the equivalent of 1.91 tons/ha(assuming of effective land conversion of 80%/ha), while the plant spacing did not show anysignificant effects the soybean production.Keywords: soybean, plant spacing, NPK fertilizerABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh jarak tanam dan aplikasi pupuk NPK terhadappertumbuhan dan hasil tanaman kedelai (Glycine max) varietas Kaba. Penelitian dilaksanakan dilahan di UPTD Balai Pengembangan Benih Palawija (BPBP), Plumbon, Cirebon, Jawa Barat daribulan April sampai dengan Juli 2014. Metode percobaan yang digunakan yaitu metode eksperimendengan Rancangan Acak Kelompok (RAK) pola faktorial dengan perlakuan terdiri dari dua faktoryang diulang tiga kali. Faktor yang pertama adalah jarak tanam yang terdiri dari tiga taraf yaitu40x10, 40x15 dan 40x20 cm, sedangkan faktor yang kedua adalah dosis pupuk NPK yang terdiri dariempat taraf yaitu 200, 250, 300 dan 350 kg/ha. Hasil penelitian menunjukkan adanya interaksiantara jarak tanam dan dosis pupuk NPK terhadap rata-rata indeks luas daun tanaman kedelaivarietas Kaba pada umur 21 hari setelah tanam. Dosis pupuk NPK Phonska 350 kg/hamenghasilkan produksi terbaik sebanyak 1,44 kg/petak atau setara dengan 1,91 ton/ha (asumsikonfersi lahan efektif 80%/ha), sedangkan jarak tanam pada perlakuan tidak menunjukkan adanyapengaruh nyata terhadap produksi kedelai.Kata kunci: kedelai, jarak tanam, pupuk NPK
