Kebutuhan tanaman sawi mengalami peningkatan sebesar 4-7% disebabkan karena peningkatan jumlah penduduk dan pendapatan masyarakat. Penelitian ini bertujuan untuk mengetahui kombinasi konsentrasi nutrisi AB Mix dan POC NASA terbaik terhadap pertumbuhan dan hasil dua jenis varietas tanaman sawi secara hidroponik FHS. Penelitian ini dilaksanakan di Rumah Kaca Fakultas Pertanian, Universitas Syiah Kuala yang berlangsung dari bulan 30 Desember 2021 sampai 24 Februari 2022. Rancangan yang digunakan yaitu Rancangan Petak Terpisah 4x2 dengan 3 ulangan. Parameter yang diamati, yaitu tinggi tanaman dan jumlah daun umur 21, 28, dan 35 HST, panjang akar, bobot basah per tanaman, bobot basah per plot, bobot basah bagian konsumsi, panjang daun, dan lebar daun. Hasil penelitian menunjukkan perlakuan kombinasi konsentrasi nutrisi AB Mix dan POC NASA berpengaruh nyata terhadap bobot basah per tanaman, bobot basah per plot, dan bobot basah bagian konsumsi. Pertumbuhan tanaman sawi terbaik dijumpai pada kombinasi konsentrasi nutrisi 9 ml/L AB Mix + 2 ml/L POC NASA. Perlakuan varietas berpengaruh sangat nyata terhadap tinggi tanaman dan jumlah daun umur 21, 28, dan 35 HST, dan lebar daun, berpengaruh nyata terhadap panjang daun. Pertumbuhan tanaman sawi terbaik dijumpai pada varietas Tosaka. Hasil penelitian juga menunjukkan adanya interaksi antara perlakuan kombinasi konsentrasi nutrisi AB Mix dan POC NASA dengan varietas berpengaruh nyata terhadap bobot basah per tanaman, bobot basah per plot, dan bobot basah bagian konsumsi. Hasil tanaman sawi terbaik dijumpai pada kombinasi konsentrasi nutrisi 9 ml/L AB Mix + 2 ml/L POC NASA pada varietas Nauli F1.

The need for mustard plants has increased by 4-7% due to an increase in population and community income. This study aims to determine the best combination of nutrient concentrations of AB Mix and POC NASA on the growth and yield of two types of mustard plant varieties using FHS hydroponics. This research was conducted at the Greenhouse of the Faculty of Agriculture, Syiah Kuala University which took place from December 30, 2021 to February 24, 2022. The design used was a 4x2 Split Plot Design with 3 replications. Parameters observed were plant height and number of leaves aged 21, 28, and 35 DAP, root length, wet weight per plant, wet weight per plot, wet weight of consumption portion, leaf length, and leaf width. The results showed that the combination treatment of nutrient concentrations of AB Mix and NASA POC had a significant effect on wet weight per plant, wet weight per plot, and wet weight for consumption. The best growth of mustard plants was found in the combination of 9 ml/L AB Mix + 2 ml/L POC NASA nutrient concentrations. Varieties treatment had a very significant effect on plant height and number of leaves aged 21, 28, and 35 DAP, and leaf width had a significant effect on leaf length. The best growth of mustard plants was found in the Tosaka variety. The results also showed that there was an interaction between the combination treatment of nutrient concentrations of AB Mix and NASA POC with varieties that significantly affected wet weight per plant, wet weight per plot, and wet weight of the consumption portion. The best mustard plant yields were found in the combination of 9 ml/L AB Mix + 2 ml/L NASA POC nutrient concentration on the Nauli F1 variety.
