Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati Azotobacter terhadap pertumbuhan jagung manis varietas SD3 IPB. Penelitian dilaksanakan di Kebun Cikabayan Kampus IPB Dramaga- Bogor pada bulan Juni-Agustus 2018. Perlakuan yang diuji terdiri dari enam perlakuan yaitu: P0: 50% NPK, P1: 100% NPK, P2: 50% NPK + 1 ml /pot pupuk hayati cair, P3: 50% NPK + 1 ml/pot Pupuk Hayati cair steril, P4: 50% NPK +5 gram /pot Pupuk Hayati Padat, P5: 50% NPK + 5 gram/pot Pupuk Hayati Padat Steril. Enam perlakuan tersebut disusun dalam Rancangan Acak Lengkap (RAL) dengan lima ulangan. Parameter pertumbuhan tanaman yang diamati meliputi jumlah daun, tinggi tanaman, berat brangkasan basah dan brangkasan kering dan bobot akar jagung. Data yang diperoleh dianalisis menggunakan ragam ANOVA dan DMRT taraf 5%. Hasil penelitian menunjukkan perlakuan P4 (50% NPK +5 gram /pot pupuk hayati padat) memiliki rata-rata tinggi tanaman yang lebih baik jika dibandingkan dengan perlakuan lain, terdapat peningkatan tinggi tanaman sebesar 4,4% jika dibandingkan dengan perlakuan P1 (100% NPK). Perlakuan P2 (50% NPK +I ml/pot pupuk hayati cair) memiliki nilai terbaik pada pembentukan jumlah helai daun dan pembentukan biomassa akar baik basah dan kering dengan nilai berurutan 15,23 gram dan 2,25 gram. Penggunaan kombinasi pupuk hayati yang diperkaya Azotobacter 33 dan NPK memberikan pengaruh yang signifikan terhadap pertumbuhan tanaman jagung pada fase vegetatif
