Pengaruh Aplikasi Media Arang Sekam dan Pupuk Organik Cair terhadap Hasil Tanaman Pakcoy (Brassica rapa L.)

This research aimed to determine: 1) the effect of the use of rice husk growing media with soil on the yield of pakcoy plants, 2) the effect of the application of liquid organic fertilizer (SO-Kontan Fert) on the yield of pakcoy plants, 3) the effect of the combination of rice husk planting media with soil and application of liquid organic fertilizer (SO-Kontan Fert) to the yield of pakcoy plants. This research was conducted from January to March 2021 at the screen house of Melung Village, Baturraden District, Banyumas Regency, Central Java and the Agronomy and Horticulture Laboratory of the Faculty of Agriculture, Jenderal Soedirman University. The experimental design used was RAKL. The first factor is M0 = without husk charcoal, M1 = soil + husk charcoal (1: 1), M2 = soil (2: 1), soil + husk charcoal (3: 1). The second factor is P0 = 0 ml POC SO-Kontan Fert/Lt water, P1 = 5 ml POC SO-Kontan Fert/Lt water, P2 = 10 ml POC SO-Kontan Fert/Lt water, P3 = 15 ml POC SO-Kontan Fert/Lt water. Results of the research showed that giving husk charcoal to pakcoy plant media at a ratio of 3:1 increased the dry crown weight.  The ratio of 2:1 increased fresh plant, dry plant weight, and fresh shoot weight. The application of liquid organic fertilizer (SO-Kontan Fert) with a concentration of 5 ml/l increased the root length.Penelitian  bertujuan untuk mengetahui pengaruh media tanam arang sekam dan pupuk organik cair (SO-Kontan Fert) terhadap hasil tanaman pakcoy. Penelitian dilaksanakan pada Januari sampai Maret 2021 di screen house Desa Melung, Kecamatan Baturraden, Kabupaten Banyumas, Jawa Tengah dan Laboratorium Agronomi dan Hortikultura Fakultas Pertanian Universitas Jenderal Soedirman. Penelitian dengan percobaan faktorial dalam Rancangan Acak Kelompok Lengkap dengan 3 ulangan sebagai blok.  Faktor pertama yaitu tanpa arang sekam, tanah + arang sekam (1:1), tanah (2:1), tanah + arang sekam (3:1). Faktor kedua konsentrasi  POC SO-Kontan Fert yaitu, 0 , 5, 10 dan 15 ml/l. Hasil penelitian menunjukkan pemberian arang sekam pada perbandingan 3 : 1 meningkatkan bobot tajuk kering. Perbandingan 2 : 1 meningkatkan bobot tanaman segar, bobot tanaman kering dan bobot tajuk segar. Pemberian pupuk organik cair (SO-Kontan Fert) konsentrasi 5 ml/l meningkatkan panjang akar. &nbsp
