Pertumbuhan tanaman pakcoy sering kali terhambat oleh berbagai faktor seperti faktor lingkungan. Upaya meningkatkan pertumbuhan dan hasil tanaman pakcoy menjadi sangat penting dilakukan. Tujuan penelitian, yaitu mengetahui pengaruh aplikasi konsorsium isolat bakteri, dosis biochar dan kombinasinya terhadap pertumbuhan dan hasil tanaman pakcoy. Penelitian ini dilaksanakan pada bulan Agustus hingga November 2023 di Screenhouse Desa Kebanggan Kecamatan Sumbang Kabupaten Banyumas. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor. Faktor pertama adalah perlakuan konsorsium bakteri yang terdiri dari perlakuan tanpa isolat bakteri, konsorsium isolat SJ3 dan CR1, dan konsorsium isolat BR2, SJ3 dan CR1. Faktor kedua adalah aplikasi biochar yang terdiri dari dosis 11,25 g, 22,5 g, dan 33,75 g. Variabel yang diamati meliputi jumlah populasi bakteri, kadar klorofil total, tinggi tanaman, jumlah daun, luas daun dan bobot segar tanaman pakcoy. Data hasil penelitian dianalisis menggunakan uji ANOVA kemudian uji lanjut Duncan (DMRT = Duncan Multiple Range Test) dengan taraf kepercayaan 95% jika data menunjukkan adanya pengaruh nyata. Hasil dari penelitian ini menunjukkan bahwa perlakuan konsorsium isolat bakteri berpengaruh nyata terhadap variabel kadar klorofil total. Namun, berpengaruh tidak nyata terhadap variabel tinggi tanaman, jumlah daun, luas daun dan bobot segar tanaman pakcoy. Perlakuan biochar berpengaruh tidak nyata terhadap variabel kadar klorofil total, tinggi tanaman, jumlah daun, luas daun dan bobot segar pakcoy. Kombinasi aplikasi konsorsium isolat bakteri dan biochar belum mampu meningkatkan kadar klorofil total, tinggi tanaman, jumlah daun, luas daun dan bobot segar tanaman pakcoy.

The growth of pakcoy plants is often hindered by various factors such as environmental factors. Efforts to improve the growth and yield of pakcoy plants are crucial. The aim of this research is to determine the effect of the application of a consortium of bacterial isolates, biochar dosage, and their combination on the growth and yield of pakcoy plants. This study was conducted from August to November 2023 at the Screenhouse of Kebanggan Village, Sumbang Subdistrict, Banyumas Regency. The method used in this research was a factorial Randomized Complete Block Design with 2 factors. The first factor was the bacterial consortium treatment consisting of treatments without bacterial isolates, consortium of isolates SJ3 and CR1, and consortium of isolates BR2, SJ3, and CR1. The second factor was the application of biochar consisting of doses of 11,25 g, 22,5 g, and 33,75 g. The observed variables included bacterial population, total chlorophyll content, plant height, number of leaves, leaf area, and fresh weight of pakcoy plants. The research data were analyzed using ANOVA and then further analyzed using Duncan's Multiple Range Test (DMRT) with a confidence level of 95% if the data showed a significant effect. The results of this study indicate that the treatment of bacterial isolate consortium significantly affects the variable of total chlorophyll content. However, it does not significantly affect the variables of plant height, number of leaves, leaf area, and fresh weight of pakcoy plants. Biochar treatment does not significantly affect the variables of total chlorophyll content, plant height, number of leaves, leaf area, and fresh weight of pakcoy. The combination of bacterial isolate consortium and biochar application has not been able to increase the total chlorophyll content, plant height, number of leaves, leaf area, and fresh weight of pakcoy plants.
