|---|
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan: 1) mengetahui pengaruh pemupukan silicon terhadap sifat kimia tanah Inceptisol, 2) mengetahui pengaruh kondisi stress air terhadap sifat kimia tanah Inceptisol, dan 3) mengetahui interaksi antara pemupukan silicon dengan kondisi stres air terhadap sifat kimia tanah Inceptisol. Penelitian ini dilaksanakan di Screen House dan laboratorium ilmu tanah, Fakultas Pertanian UNSOED, dari bulan November 2019 sampai Juli 2020. Penelitian ini menggunakan Rancangan Acak Kelompok dengan dua perlakuan, yaitu pupuk silicon (kontrol, 5 g/polybag, 10 g/polybag dan 15 g/polybag) dan kondisi stress air (100%, 90%, 80%, dan 70%) yang diulang sebanyak 3 kali. Variabel pengamatan meliputi kandungan Si oksalat tanah, pH H2O, pH KCl, N tersedia, N total, P tersedia, P total, K tersedia, K total, KTK, Al-dd tanah. Data dianalisis dengan uji F dan uji lanjut dengan DMRT dengan tingkat kesalahan 5%. Hasil penelitian menunjukkan pemupukan silicon meningkatkan K tersedia dan K-total tetapi tidak meningkatkan Si oksalat tanah, pH H2O, pH KCl, N tersedia, N total, P tersedia, P total, KTK, dan Al-dd tanah. Kondisi stress air menurunkan pH H2O, pH KCl, dan Al-dd tetapi tidak mempengaruhi kandungan Si oksalat tanah, N tersedia, N total, P tersedia, P total, K tersedia dan K-total, serta KTK. Tidak terdapat interaksi antara pemberian pupuk silicon dan kondisi stress air. |

| Abtrak (Bhs. Inggris) | This study aims: 1) to determine the effect of silicon fertilization on the chemical properties of Inceptisol soil, 2) to determine the effect of water stress conditions on the chemical properties of Inceptisol soil, and 3) to determine the interaction between silicon fertilization and water stress conditions on the chemical properties of Inceptisol soil. This research was conducted at the Screen House and soil science laboratory, Faculty of Agriculture, UNSOED, from November 2019 to July 2020. This research used a randomized block design with two treatments, namely silicon fertilizer (control, 5 g / polybag, 10 g / polybag and 15 g / polybag) and water stress conditions (100%, 90%, 80%, and 70%) which were repeated 3 times. The observation variables included soil Si oxalate content, pH H2O, pH KCl, available N, total N, available P, total P, available K, total K, CEC, soil Al-dd. Data were analyzed by F test and further test with DMRT with an error rate of 5%. The results showed that silicon fertilization increased available K and total K but did not increase soil Si oxalate, pH H2O, pH KCl, available N, total N, available P, total P, CEC, and Al-dd. Water stress conditions lowered the pH of H2O, pH of KCl, and Al-dd of the soil but did not affect the Si oxalate content of the soil, available N, total N, available P, total P, available K and K-total, and CEC. There is no interaction between the application of silicon fertilizer and water stress conditions. |
