Abstract

ABSTRAK

 

Tujuan penelitian ini adalah mengamati daya tumbuh benih jagung hibrida varietas P31, varietas P35 dan varietas kompetitor, dan mengamati daya tahan benih jagung hibrida varietas P31, varietas P35 dan varietas kompetitor terhadap serangan penyakit Bulai. Metode pengamatan yang dilakukan di perusahaan yang pertama adalah penanaman benih jagung meliputi persiapan alat dan bahan sebelum tanam, persiapan lahan pengamatan, penanaman, pemberian pupuk pertama, dan penyiangan. Langkah kedua adalah pengamatan dan pengambilan data meliputi pengamatan daya tumbuh, proses inokulasi dan pengambilan data intensitas serangan penyakit Bulai. Dari hasil pengamatan pada 10 HST (Hari Setelah Tanam) diketahui bahwa daya tumbuh varietas P31 (93%), varietas P35 (98%) dan varietas kompetitor (92%). Kemudian tanaman jagung yang tergolong sangat tahan bulai adalah varietas P35 (9,18%), tanaman varietas P31 (13,98%) tergolong tahan dan varietas kompetitor agak tahan (36,94%), pada pengamatan intensitas serangan penyakit Bulai 40 HST.
