Abstract: Jagung manis (Zea mays saccharata Sturt L.) merupakan salah satu komoditas pangan utama yang memiliki peran strategis dalam mendukung perekonomian nasional. Kebutuhan akan jagung terus meningkat, terutama untuk konsumsi langsung. Oleh karena itu, produktivitas jagung harus ditingkatkan. Salah satunya melalui metode pemupukan yang tepat. Pupuk NPK menjadi salah satu alternatif yang banyak digunakan karena mengandung unsur hara makro esensial seperti nitrogen (N), fosfor (P), dan kalium (K) yang dibutuhkan tanaman dalam jumlah besar. Pupuk NPK mampu meningkatkan pertumbuhan tanaman jagung secara signifikan karena membantu mencukupi kebutuhan unsur hara pada tanaman. Penelitian dilaksanakan di Kebun Percobaan IPB Sabisa Farm, Sindangbarang, Kecamatan Bogor Barat, Kota Bogor, Jawa Barat selama 4 bulan, dari bulan September 2022 hingga Desember 2022. Percobaan ini menggunakan rancangan kelompok lengkap teracak (RKLT) faktor tunggal. Perlakuan dosis pupuk disusun dalam 6 taraf pemupukan yaitu: (1) tanpa pemberian pupuk yang diuji (Kontrol); (2) pupuk NPK standar sebagai pembanding (NPK standar); (3) 0,5 dosis pupuk uji (0,5 NPK); (4) 1,0 dosis pupuk uji (1,0 NPK); (5) 1,5dosispupuk uji (1,5 NPK); (6) 2,0 dosis pupuk uji (2,0 NPK). Hasil dari penelitian ini menunjukkan bahwa pupuk uji berpengaruh nyata terhadap pertumbuhan vegetatif. Pada hasil generatif, hasil tertinggi dicapai oleh perlakuan P6, yang memiliki nilai efektivitas agronomi relatif (EAR) 114%. Nilai tersebut lebih tinggi dibandingkan perlakuan standar (P1) yang bernilai 100%.
Sweet corn (Zea mays saccharata Sturt L.) is one of the main food commodities with a strategic role in supporting the national economy. The demand for corn continues to increase, especially for direct consumption. Therefore, efforts to increase corn productivity are essential. One such effort is through the application of appropriate fertilization methods. NPK fertilizer has become a widely used alternative, as it contains essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), which are required by plants inlarge quantities. NPK fertilizer significantly enhances the growth of corn plants byfulfilling their nutrient needs.This study was conducted at the IPB Experimental Farm, Sabisa Farm, located in Sindangbarang, West Bogor District, Bogor City, West Java, for a duration of four months, from September 2022 to December 2022. The experiment used a single-factor randomized complete block design (RCBD). The fertilizer treatments consisted of six levels: (1) no fertilizer application(Control); (2) standard NPK fertilizer (Standard NPK); (3) 0.5 dosage of the testedNPK fertilizer (0.5 NPK); (4) 1.0 dosage of the tested NPK fertilizer (1.0 NPK); (5) 1.5 dosage of the tested NPK fertilizer (1.5 NPK); (6) 2.0 dosage of the testedNPK fertilizer (2.0 NPK).The results of this study indicated that the testedfertilizer had a significant effect on vegetative growth. For generative yield, the highest result was achieved by treatment P6, which had a relative agronomic effectiveness (RAE) value of 114%. This value was higher than the standardtreatment (P1), which had an RAE of 100%.
