Abstract

Sorgum belum banyak ditanam di daerah Sumatera Utara, sehingga perlu diteliti untuk mengetahui kemampuannya beradaptasi pada lingkungan yang berbeda. Penelitian ini bertujuan untuk melihat kemampuan adaptasi enam varietas sorgum dengan menanam sorgum pada dua kondisi lingkungan dan ketinggian tempat yang berbeda, yaitu di dataran rendah dan dataran tinggi. Penelitian ini dilakukan di dataran rendah dan dataran tinggi, yaitu Lubuk Pakam (200 mdpl) dan Tongkoh Berastagi (1450 mdpl). Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non faktorial, yaitu varietas sorgum yaitu Numbu, Super 1, Super 2, Soper 7, Soper 9 dan Suri 4 dengan empat kali ulangan. Parameter yang diamati adalah karakter morfologi, karakteristik stomata dan kandungan klorofil. Hasil penelitian menunjukkan bahwa semua tanaman di Lubuk Pakam lebih tinggi dibandingkan dengan tanaman sorgum di Berastagi dimana tanaman tertinggi terdapat pada varietas V3, Super 2, diikuti oleh Super 1 dan Soper 9. Jumlah klorofil a, b dan total klorofil tidak dipengaruhi secara nyata oleh perbedaan varietas, baik di dataran tinggi maupun dataran rendah. Namun demikian, terdapat perbedaan pola respon tanaman dalam menghadapi lokasi lingkungan yang berbeda melalui jumlah klorofil a dan klorofil b.

Abstract

Maize is one of the staple food crops in the world, but the entry of Spodoptera frugiperda pests has reduced national maize production. Most farmers control these pests by using pesticides that cause harm to human health and the environment, so that other environmentally friendly control alternatives are needed, namely the use of resistant varieties. This study aims to obtain maize varieties that are resistant to Spodoptera frugiperda attacks. This study used a one-factor Randomized Block Design (RBD), namely maize varieties, consisting of five varieties, namely: Bisi 2, Bisi 18, Pertiwi 3, Pioneer 32, and NK 212. Each variety was repeated five times. Based on the results of observations of vegetative and generative growth parameters, it was obtained that the NK 212 variety had the best growth and production compared to other varieties. Meanwhile, the results of observations of Spodoptera frugiperda attacks showed that Pioneer 32 was a resistant variety with the lowest attack intensity. Although the NK 212 variety showed the best growth and yield, the Pioneer 32 variety proved to be more resistant to pest attacks. Therefore, variety selection must consider the balance between pest resistance and potential production results.
