Uji Ketahanan Beberapa Varietas Padi (Oryza sativa L.) terhadap Hama Kepik Hitam Paraeucosmetus pallicornis Dallas. (Hemiptera: Lygaedae) di Rumah Kasa

Resistance Test of Rice (Oryza sativa) Varieties to Paraeucosmetus pallicornis Dallas. (Hemiptera: Lygaedae) in The Screen House

Abstract

The research was aimed to determine the resistance of rice varieties against Paraeucosmetus pallicornis in screen house. This research was conducted in the screen house of Universitas Sumatera Utara from July until November 2017 using factorial randomized block design (RBD) with two factors and four replications. The first factor was the time of introduction (4, 6, 8, 10 weeks after planting) and the second factor was rice varieties (Ciherang, Inpari 32, Mekongga, dan Mapan P-05). The results showed that all of varieties were classified as scale 1 (resistant) against P. pallicornis. The highest ratio the intensity of attack tested based on time introduction was 10, 4 , 8, and 6 week after planting respectively.

Penelitian ini bertujuan untuk mengetahui ketahanan beberapa varietas padi terhadap hama kepik hitam P. pallicornis di rumah kasa. Penelitian dilaksanakan di rumah kasa fakultas petanian Universitas Sumatera Utara pada bulan Juli sampai November 2017 menggunakan rancangan acak kelompok faktorial dengan dua faktor dan empat ulangan. Faktor pertama waktu introduksi hama (4, 6, 8, 10 minggu setelah tanam) dan faktor kedua yaitu varietas padi (Ciherang, Inpari 32, Mekongga, dan Mapan P-05). Hasil penelitian menunjukkan bahwa seluruh varietas tergolong skala 1 (tahan) terhadap P. pallicornis dan perbandingan intensitas serangan yang diuji berdasarkan waktu introduksi dari yang tertinggi yaitu 10, 4, 8, dan 6 minggu setelah tanam.
