Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh jarak tanam dan dosis pupuk NPK terhadap pertumbuhan dan
hasil jagung manis pada pertanaman pisang cavendish. Penelitian dilaksanakan pada bulan Agustus sampai November 2021
di Kebun Percobaan Fakultas Pertanian Universitas Mulawarman, L2, Tenggarong Seberang. Penelitian ini disusun dalam
Rancangan Acak Kelompok (RAK) dibagi dalam tiga kelompok yang terdiri dari dua faktor perlakuan, faktor 1 yaitu jarak
tanam (J) terdiri dari : J1 = 50 x 25 cm, J2 = 75 x 25 cm, dan J3 = 100 x 25 cm. Faktor 2 yaitu dosis pupuk NPK (P) terdiri
dari : P1 = 250 kg.ha-1, P2 = 500 kg.ha-1, dan P3 = 750 kg.ha-1. Hasil uji lanjut menunjukkan bahwa perlakuan jarak tanam
memberikan pengaruh yang berbeda terhadap umur berbunga betina, hasil bobot tongkol berkelobot dan tanpa kelobot per ha.
Hasil bobot tongkol berkelobot tertinggi diperoleh pada perlakuan J1 (50 x 25 cm), yaitu 2.16 Mg. Perlakuan dosis pupuk
NPK memberikan pengaruh yang berbeda terhadap umur berbunga betina, panjang tongkol tanpa kelobot, bobot tongkol tanpa
kelobot per petak, hasil bobot tongkol berkelobot dan tanpa kelobot per ha. Hasil bobot tongkol berkelobot tertinggi diperoleh
pada perlakuan P3 (750 kg.ha-1), yaitu 1.96 Mg. Interaksi antara perlakuan jarak tanam dan dosis pupuk NPK memberikan
pengaruh yang berbeda terhadap seluruh parameter pengamatan, kecuali hasil bobot tongkol jagung manis berkelobot per ha.
