Pertumbuhan bibit yang baik mempunyai pengaruh yang sangat besar terhadap pertumbuhan dan perkembangan tanaman. Penelitian bertujuan mengetahui pengaruh komposisi media tanam organik yang berbeda terhadap pertumbuhan bibit tanaman pacar air (Impatiens balsamina L.). Penelitian dilaksanakan di desa Kamal, Madura dengan ketinggian tempat 5 mdpl pada bulan Maret - April 2017. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap dengan 7 perlakuan yaitu A = tanah mediteran (kontrol), B = tanah mediteran : pupuk kandang sapi (1:1), C = tanah mediteran: pupuk kandang sapi (1:2), D = tanah mediteran : pupuk kandang kambing (1:1), tanah mediteran : pupuk kandang kambing (1:2), F = tanah mediteran: kompos (1:1), G = tanah mediteran : kompos (1:2). Hasil penelitian menunjukkan bahwa perlakuan media tanah mediteran : kompos (1:2) memberikan hasil terbaik pada variabel tinggi tanaman dan jumlah daun pada awal pengamatan namun pada akhir pengamatan perlakuan media tanah mediteran : pupuk kandang sapi (1:2) memberikan hasil terbaik. Perlakuan media tanah mediteran: kompos (1:2) memberikan hasil terbaik pada variabel pengamatan potensi tumbuh maksimum, indeks vigor, sedangkan perlakuan media tanam tanah mediteran : pupuk kandang sapi (1:2) memberikan hasil terbaik pada variabel pengamatan bobot basah tanaman dan bobot kering tanaman. Kata Kunci : Pacar air (Impatiens balsamina L.), pertumbuhan bibit, tanah mediteran, pupuk kandang sapi, pupuk kandang kambing, kompos.

Growth of good seedlings has a very large influence on the growth and development of plants. The aim of this research is to know the infuence of different organic plant media composition on the growth of seedlings of balsam (Impatiens balsamina L.). The research was conducted in Kamal village, Madura with the height of 5 mdpl place in March - April 2017. The research design used was Completely Randomized Design with 7 treatments is A = mediteran land (control), B = mediteran soil: cow manure (1:1), C = mediteran soil : cow manure (1:2), D = mediteran soil : goat manure (1:1), E = mediteran soil: cow manure (1:2) F = mediteran soil: compost (1:1), G = mediteran soil : compost (1:2). The results showed that mediteran soil media treatment: compost (1:2) gave the best result on plant height variable and leaf number at the beginning of observation but at the end of observation mediteran soil media treatment: cow manure (1:2) gave the best result. The mediteran soil media treatment: compost (1:2) gives the best result on observation variable of maximum growth potential,vigor index, mediteran medication treatment : cow manure (1:2) gives best result on observation variable of wet weight of plant and weight dry plants. Keywords: Balsam (Impatiens balsamina L.), seedling growth, mediteran land, cow manure, goat manure, compost.
