Maize is one of the staple food crops in Indonesianthat must be developed its genetic diversity. The objective of this study was to obtain the appearance of vegetative and reproductive character of some F1 maize populations on peat soil stress with pH criteria of 5.9 and peat soil with sludge and ash of oil palm. The research was conducted at Setiabudi field, Tanjung Rejo sub-district, Medan city from April to August 2017. This research used Randomized Block Design (RAK) with 2 treatment factors. The first factor is the population consisting of 5 levels:A (NEI9008 x CLA46), B: (NEI9008 x CLA106), C: (CLA106 x NEI9008),D: (CLA16 x CLA84), E: (CLA84 x NEI9008) and the second factor was planting medium consisting of 3 levels is M1 (peat soil), M2 (peat soil + ash of oil palm), M3 (peat soil + sludge). The results showed that the interaction of planting media with F1 population of maize plant had significant effect on plant height character. The best media was found in M3 (peat soil + sludge).
Jagung merupakan salah satu tanaman pangan pokok di Indonesia yang harus dikembangkan keanekaragaman genetiknya. Tujuan dari penelitian ini untuk memperoleh penampilan karakter vegetatif dan reproduktif beberapa populasi F1 jagung pada cekaman tanah gambut dengan kriteria pH 5.9 dan tanah gambut yang diberi sludge dan abu janjang kelapa sawit. Penelitian dilaksanakan di daerah Setiabudi, kecamatan Tanjung Rejo, kota Medan pada April sampai Agustus 2017. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 2 faktor perlakuan. Faktor pertama adalah populasi yang terdiri dari 5 taraf yaitu : A(NEI9008 x CLA46), B : (NEI9008 x CLA106), C : (CLA106 x NEI9008), D : (CLA16 x CLA84), E : (CLA84 x NEI9008)dan faktor kedua adalah media tanam terdiri dari 3 taraf yaitu M1 (gambut), M2 (gambut+abu janjang), M3 (gambut+sludge). Hasil penelitian menunjukkan bahwa Interaksi media tanam dengan populasi F1 tanaman jagung berpengaruh nyata terhadap karakter tinggi tanaman. Media terbaik terdapat pada M3 (gambut+sludge).
