Abstract

Tujuan penelitian ini untuk menentukan pengaruh rhizobakteri pada pertumbuhan, klorofil dan kandungan allicin tanaman bawang merah (Allium ascalonicum L.) dalam kondisi salin. Penelitian ini dilakukan di Rumah Kaca di Agrotechnopark Universitas Brawijaya, Desa Jatikerto, Malang-Indonesia yang dilaksanakan mulai bulan Februari hingga Juni 2018. Strain rhizobakteri yang digunakan terdiri dari isolat-isolat bakteri toleran salin berasal dari tanah salin di pesisir Lamongan, Jawa Timur, Indonesia dengan kode isolat SN13 (Streptomyces sp.), SN22 (Bacillus sp.) and SN23 (Corynebacterium sp.). Rancangan percobaan yang digunakan dalam penelitian ini adalah rancangan petak terbagi (split plot), terdiri dari kondisi salin sebagai petak utama dan konsentrasi bakteri toleran salin sebagai anak petak. Hasil penelitian menunjukkan bahwa tanaman yang diinokulasi bakteri mempunyai bobot kering akar yang sangat nyata lebih tinggi (22.10 - 30%), jumlah klorofil (mencapai 26.03%) lebih tinggi dibandingkan tanpa inokulasi, tetapi memiliki allicin pada umbinya lebih rendah. Aplikasi bakteri toleran salin dapat memperbaiki pertumbuhan tanaman dalam kondisi salin. Kondisi salin menurunkan baik pertumbuhan dan hasil tanaman bawang merah, namun meningkatkan kandungan prolin. Peningkatan konsentrasi prolin pada daun merupakan respon fisiologis dari tanaman bawang merah pada kondisi salin. Kata kunci: allisin, klorofil, prolin, salinitas, umbi

Abstract

Tomatoes are a horticultural commodity and the main priority to be developed in Indonesia. To improve the production of tomatoes, land expansion is needed. Managing marginal land to grow tomatoes can be an option. Marginal land such as saline land has the potential to be developed as an alternative. This research is aimed to investigate the effect of K fertilizer on the growth and yield of tomato plants at different levels of salinity. The experiment was conducted in a greenhouse located in the rural area of Bendosari in Kediri, East Java, using factorial randomized block design. The first factor was NaCl concentration (0, 3000, 6000 and 9000 ppm) while the second factor was the dosage of ZK fertilizer (75, 150 and 225 kg/ha). The results Showed that salinity level reduced growth and yield of tomato while the dosage of ZK fertilizer did not affect. Salinity level on 3000 ppm reduced leaf area 20.35 %, shoot dry weight 27.18%, root dry weight 28 %, number of fruit 24.14 %, fruit weight per fruit 29.82 % and fruit weight per plant 12.42 %. However, salinity level on 6000 and 9000 ppm ware not significantly different at all variables except 6000 ppm in leaf area (reduced 37.06%) and 9000 ppm on the number of fruit (reduced 43.01%).
