| Judul Artikel | Pengaruh Pemupukan Silika (Si) dan Kondisi Stres Air Terhadap Pertumbuhan dan Hasil Tanaman Pakcoy (Brassica rapa L.) pada Tanah Inceptisol”. |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk: 1) mengetahui pengaruh pemupukan Silika (Si) terhadap pertumbuhan dan hasil tanaman pakcoy, 2) mengetahui pengaruh kondisi stress air terhadap pertumbuhan dan hasil tanaman pakcoy, dan 3) mengetahui interaksi anatara pemupukan Silika (Si) dengan kondisi stres air terhadap pertumbuhan dan hasil tanaman pakcoy. Penelitian ini dilaksanakan di Screen House, Fakultas Pertanian Universitas Jenderal Soedirman, dari bulan Mei 2019 sampai Agustus 2019. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan dua perlakuan, yaitu pupuk Silika (kontrol, 5 g/polybag, 4 g/polybag, 10 g/polybag dan 15 g/polybag) dan kondisi stress air (100%, 90%, dan 80%) yang diulang sebanyak 3 kali dengan masing – masing unit percobaan terdapat 2 polybag. Variabel pengamatan meliputi tinggi tanaman, jumlah daun, luas daun, kehijauan daun, panjang akar, bobot tajuk segar, bobot tajuk kering, bobot akar segar, bobot akar kering, bobot tanaman segar dan bobot tanaman kering. Data dianalisis dengan uji F (ANOVA) dan uji lanjut dengan Duncan’s Multiple Range Test (DMRT) dengan tingkat kesalahan 5%. Hasil penelitian menunjukkan bahwa pemupukan Silika yang berasal dari Zeolit dan kompos ampas tebu (bagasse) dapat meningkatkan tinggi tanaman sebesar 16,28 cm, jumlah daun sebesar 11,89 helai dan kehijauan daun 56,84 unit/cm2. Perlakuan kondisi stress air dapat meningkatkan jumlah daun sebesar 11,92 helai dan kehijauan daun sebesar 55,79 unit/cm2. Tidak terdapat interaksi antara pemberian pupuk Silika (Si) dan kondisi stress air. Kata kunci : Silika (Si), Kompos Ampas Tebu, Zeolit, Stress Air, Pakcoy (Brassica rapa L.) |
| Abtrak (Bhs. Inggris) | The purpose of this research is: 1) to know the effect of Silica (Si) fertilization on the gowth and yield of pakcoy; 2) to know the effect of water stress conditions on the gowth and yield of pakcoy; and 3) to know the interactions between Silica fertization and water stress conditions on the gowth and yield of pakcoy. The research was conducted at the Screen house, Faculty of Agiculture, Jenderal Soedirman University, from May 2019 to August 2019. This study used a Randimized Block Design (RBD) with two treatments namely Silica fertilizer (control, 5 g/polybag, 10 g/polybag, 15 g/polybag) and (100%, 90%, and 80% water stress conditions) were repeated 3 times with each treatment containing 2 polybags. Observation variables included plant height, number of leaves, leaf area, leaf geenness, root length, fresh crown weight, dry crown weight, fresh root weight, dry weight, fresh plant weight and dry plant weight. Data were analyzed by F test (ANOVA) and further tests by Duncan’s Multiple Range Test (DMRT) with an error rate of 5%. The result of this research showed that Silica fertilization derived from Zeolite and bagasse compost could increase height by 16.28 cm, number of leaves by 1189 strands and leaf geening by 56.84 units/cm2. The treatment of water stress conditions can increase the number of leaves of 11.92 strands and the geenness of the leaves by 55.79 units/cm2. There is no interaction between giving Silica (Si) fertier and water stress conditions. Both treatments affect the gowth variable. |
