Penelitian ini bertujuan untuk 1) mengetahui pengaruh komposisi media tanam terhadap pertumbuhan dan hasil tanaman kailan, 2) mengetahui pengaruh dosis pupuk nitrogen terhadap pertumbuhan dan hasil tanaman kailan, 3) mengetahui pengaruh  kombinasi komposisi media tanam dan dosis pupuk nitrogen terhadap pertumbuhan dan hasil tanaman kailan. Penelitian dilaksanakan di screen house Fakultas Pertanian, Universitas Jenderal Soedirman dengan ketinggian 110 mdpl pada bulan Januari sampai Februari 2016. Rancangan yang digunakan adalah Rancangan Acak Kelompok dengan 2 faktor dan 3 kali ulangan. Variabel yang diamati adalah tinggi tanaman, jumlah daun, luas daun, bobot tanaman segar, bobot tajuk segar, bobot tajuk kering, bobot akar segar, dan bobot akar kering. Hasil penelitian menunjukkan bahwa komposisi media tanam meningkatkan tinggi tanaman, jumlah daun, luas daun, bobot tajuk segar dan bobot tanaman segar. Komposisi media tanam terbaik adalah media tanah, cocopeat dan arang sekam dengan perbandingan 2:1:1. Dosis pupuk nitrogen meningkatkan semua variabel. Dosis pupuk nitrogen yang tepat adalah 100 kg N/ha. Kombinasi komposisi media tanam dan dosis pupuk nitrogen meningkatkan tinggi tanaman dan jumlah daun. Kombinasi perlakuan yang tepat terdapat pada komposisi media tanah, cocopeat dan arang sekam dengan perbandingan 2:1:1 dan dosis pupuk nitrogen 100 kg N/ha.

This research aims to 1) know the effect of the composition of growing media on growth and yields of chinese kale, 2) know the effect of dosage of nitrogen fertilizer on growth and yields of Chinese kale, 3) know the effect of combination between composition of growing media and dosage of nitrogen fertilizer on growth and yields of chinese kale. Research had been conducted in screen house the Faculty of Agriculture, University of Jenderal Soedirman with altitude 110 metres above sea level from January to February 2016. The design used was Randomized Block Design (RBD) with 2 factors and 3 replications. The observed variables were plant height, number of leaves, leaf area, fresh plant weight, fresh canopy weight, dry canopy weight, fresh root weight, and dry root weight. The results of research showed that composition of growing media increased plant height, number of leaves, leaf area, fresh plant weight, fresh canopy weight. The best composition of media was in the type of soil,cocopeat and chaff charcoal in the ratio 2:1:1. Dosage of nitrogen fertilizer increased all observed variables. The accurate dosage of nitrogen fertilizer was 100 kg N/ha. Combination between of composition of growing media and dosage of nitrogen fertilizer increased plant height and number of leaves. The accurate combination between of composition of growing media and dosage of nitrogen contained  soil, cocopeat and chaff charcoal in the ratio 2:1:1 and dosage of nitrogen fertilizer was 100 kg N/ha.
