Daftar Isi:
- Corn (Zea mays L.) is an important food because corn is the second source of carbohydrates after rice. Seeds are one of the important components in the successful increase of agricultural production. This study aims to determine the type of fungi associated to corn seed (Zea mays L.) conducted from April to May 2017 at the faculty of agriculture, Timor University. Using Completely Randomized Design (RAL) Factorials and methods used are sampling, observation and pathogen identification performed by morphological characterization, Seedling power testing and maximum growth potential by the UKDdp method. The seeds used are small white local varieties, large white local varieties and hybrids, derived from several localities based on the locality of Eban 1000 meters above sea level, Mamsena 400-800 meters above sea level, Wini 100-200 meters above sea level. The results of identification were obtained by two genera of Aspergillus sp1, Aspergillus sp2, Aspergillus sp3 and Fusarium sp, Aspergillus sp1 highest fungal attack on small local varieties 7.78% and height of place T2 (Wini), Fusarium sp highest on hybrid corn varieties 40.00% and height of the highest place on T1 (Eban) 8.67%. The test of seed germination in the three varieties ranged between 16.44% -26.00%.
- Jagung merupakan bahan pangan yang penting karena jagung merupakan sumber karbohidrat kedua setelah beras. Benih salah satu komponen penting dalam keberhasilan peningkatan produksi pertanian. Penelitian ini bertujuan untuk mengetahui jenis cendawan yang berasosiasi pada benih jagung, dilakukan bulan April sampai bulan Mei 2017 di laboratorium Fakultas Pertanian Universitas Timor. Penelitian menggunakan Rancangan Acak Lengkap (RAL) Faktorial. Identifikasi patogen dilakukan dengan karakterisasi morfologi, selain itu dilakukan pengujian daya berkecambah benih dan potensi tumbuh maksimum dengan metode UKDdp. Benih yang digunakan adalah varietas Lokal Putih kecil, varietas lokal putih besar dan hibrida, berasal dari beberapa daerah berdasarkan ketinggian tempat yakni Eban 1000 mdpl, Mamsena 400-800 mdpl, Wini 100-200 mdpl. Hasil identifikasi didapatkan dua genus yaitu Aspergillus sp1, Aspergillus sp2, Aspergillus sp3 dan Fusarium sp, serangan cendawan Aspergillus sp1 tertinggi pada varietas lokal kecil 7,78% dan ketinggian tempat T2 (Wini), Fusarium sp tertinggi pada varietas jagung hibrida 40,00% dan ketinggian tempat tertinggi pada T1 (Eban) 8,67%. Pengujian daya kecambah benih pada ketiga varietas berkisar antara 16,44%-26,00%.
