Abstract

Jagung mempunyai peran strategis bagi perekonomian nasional, jagung penyumbang terbesar kedua setelah padi dalam subsektor tanaman pangan. Uji adaptasi merupakan kegiatan uji lapangan terhadap tanaman dibeberapa agroekologi bagi tanaman untuk mengetahui keunggulan dan interaksi varietas terhadap lingkungan. Tujuan penelitian ini adalah mengetahui galur jagung hibrida rakitan Politeknik Negeri Lampung yang mampu beradaptasi di dataran menengah. Penelitian ini dilaksanakan di Desa Gisting Kabupaten Tanggamus pada bulan September 2017 – Februari 2018 dengan metode Rancangan Kelompok Teracak Sempurna (RKTS) yang terdiri dari 1 faktor yaitu galur, 3 ulangan, 5 genotipe yaitu 4 galur A (PL 300 X PL 403), B (PL 101 X PL 401), C (PL 401 X PL 101), D (PL 403 X PL 300) dan varietas NK 22 sebagai pembanding. Hasil penelitian uji adaptasi pada dataran menengah Tanggamus menunjukkan bahwa galur A, B, C, dan D mampu beradaptasi pada dataran menengah dapat dilihat dari hasil biji per hektar yang setara dengan varietas pembanding.Kata kunci : Dataran menengah, jagung, uji adaptasi.

Abstract

In addition to plant treatment in the field, the processing method also effects to the quality of chili seeds. Information on this matter is still limited. This research was conducted to determine the effects of chili type and processing method on chili seed quality. The treatments of three types of chillies (big, curly and cayenne) with two processing methods (manual wet and by machine) was carried out at the Vegetables Crops Research Institute from February to May 2018. Seed quality observations were carried out using the ISTA method for parameters of seed moisture content and germination. The result showed that the seed water content was affected by the type of chili and the processing method. Manual processing of chili seeds produces seeds with lower seed moisture content (7.86%) compared to machine processing (8.44%). Seed moisture content from the lowest to the highest was successively produced by curly chili, big chili and cayenne chili at 7.39%, 8.01%, and 9.05%. The germination of seeds from manual processing was significantly higher than that from machine processing (39.83%). The germination of curly chili seeds (53.13%) was not significantly different from that of big chili (49.63%) but significantly different from that of cayenne pepper (33.00%).
