| Judul Artikel | Respons Tiga Varietas Sawi Hijau (Brassica juncea L.) pada Berbagai Media Tanam terhadap Fisiologi dan Hasil secara Hidroponik Deep Flow Technique (DFT) |
| Abstrak (Bhs. Indonesia) | Sawi hijau (Brassica juncea L.) pada sistem hidroponik Deep Flow Technique (DFT) dapat menunjukkan respons fisiologi dan hasil yang berbeda akibat perbedaan media tanam dan varietas. Penelitian ini bertujuan mengetahui pengaruh media tanam, varietas, serta interaksi keduanya terhadap fisiologi dan hasil tanaman sawi hijau pada sistem hidroponik DFT. Penelitian dilaksanakan pada Februari– Maret 2026 di Greenhouse Dusun Gupakan, Desa Srowot, Kecamatan Kalibagor, Kabupaten Banyumas dan Laboratorium Agronomi dan Hortikultura Fakultas Pertanian Universitas Jenderal Soedirman. Penelitian menggunakan Rancangan Petak Terbagi (Split-Plot) dengan media tanam sebagai petak utama, yaitu rockwool (M1), arang sekam (M2), dan cocopeat (M3), serta varietas sebagai anak petak, yaitu Shinta (V1), Tosakan (V2), dan Kumala (V3). Sembilan kombinasi perlakuan diulang tiga kali sehingga diperoleh 27 unit percobaan. Data dianalisis menggunakan ANOVA dan DMRT taraf 5%. Media tanam berpengaruh nyata terhadap ILD 21 HST, LPT, volume akar, dan bobot kering tajuk. Rockwool menghasilkan ILD 0,89, LPT 6,66 g m⁻² hari⁻¹, dan bobot kering tajuk 2,53 g, sedangkan volume akar tertinggi diperoleh pada cocopeat sebesar 3,54 cm³. Varietas berpengaruh sangat nyata terhadap SPAD 21 dan 28 HST serta nyata terhadap ILD 21 HST dan kerapatan stomata. Shinta menghasilkan SPAD 33,17 dan 35,26 pada 21 dan 28 HST, ILD 0,64, serta kerapatan stomata 413,45 stomata mm⁻². Interaksi media tanam × varietas berpengaruh nyata terhadap LAB, dengan M1V3 tertinggi sebesar 1,31 mg cm⁻² hari⁻¹ dan M3V3 terendah sebesar 0,40 mg cm⁻² hari⁻¹. |
| Abtrak (Bhs. Inggris) | Mustard green (Brassica juncea L.) under Deep Flow Technique (DFT) hydroponics may show different physiological and yield responses due to differences in growing media and varieties. This study aimed to determine the effects of growing media, varieties, and their interaction on the physiology and yield of mustard green under DFT hydroponics. The experiment was conducted from February to March 2026 in a greenhouse in Gupakan Hamlet, Srowot Village, Kalibagor District, Banyumas Regency, and at the Agronomy and Horticulture Laboratory, Faculty of Agriculture, Universitas Jenderal Soedirman. A Split- Plot Design was used, with rockwool (M1), rice husk charcoal (M2), and cocopeat (M3) as main plots and Shinta (V1), Tosakan (V2), and Kumala (V3) as subplots. Nine treatment combinations were replicated three times, resulting in 27 experimental units. Data were analyzed using ANOVA and DMRT at 5%. Growing media significantly affected LAI at 21 days after planting, crop growth rate, root volume, and shoot dry weight. Rockwool produced LAI of 0.89, crop growth rate of 6.66 g m⁻² day⁻¹, and shoot dry weight of 2.53 g, whereas cocopeat produced the highest root volume of 3.54 cm³. Variety had highly significant effects on SPAD at 21 and 28 days after planting and significant effects on LAI at 21 days and stomatal density. Shinta produced SPAD values of 33.17 and 35.26, LAI of 0.64, and stomatal density of 413.45 stomata mm⁻². The interaction between growing media and variety significantly affected net assimilation rate, with M1V3 producing 1.31 mg cm⁻² day⁻¹ and M3V3 producing 0.40 mg cm⁻² day⁻¹. |
