Pengaruh Pupuk Silika Terhadap Pertumbuhan dan Produksi Kedelai pada Tanah Salin

Abstract

<p>Silica fertilizer is applied to the soil for the purpose of reducing the effects of salinity stress. This research study was conducted to examine the effect of fertilization ratio with different sources of silica to soybean growth and production on saline soil. The methods used was Completely Randomized Factorial Designs 2 x 6 with 3 replications. The first factor was soil salinity levels (A), consists of A1 (±3 dS/m) and A2 (±6 dS/m). The second factor was different silica fertilizer aplications (B) which consists of B0 (without silica), B1 (100% zeolite), B2 (75% zeolite, 25% liquid silica), B3 (50% zeolite, 50 % liquid silica), B4 (25% zeolite, 75% liquid silica), and B5 (100% liquid silica). Parameters observed in this research were plant height, number of leaves, number of pods, pod weight, number of seed and seed weight. Data was analyzed by analysis of variance followed by Duncan's Multiple Range Test. The result showed that the application of silica fertilizer through soil and leaves (50% zeolite, 50 % liquid silica) improved the growth and yield of soybean on soil with moderately saline (3 dS/m). application of silica fertilizer (50% zeolite, 50 % liquid silica) improved the growth and yield of soybean. The higher soil salinity reduced soybean growth and yield. Moreover, the utilization of silica minimized the decrease in soybean growth and yield.</p>

Exploration, Screening, and Application of Silica Solubilizing Bacteria and Silica Fertilizer to Suppress Fusarium Wilt Disease in Abaca

“…Hal ini diduga karena kemampuan BPS yang rendah dalam melarutkan silika sehingga silika kurang optimal diserap tanaman. Pemberian pupuk silika tidak berpengaruh nyata terhadap peubah pertumbuhan tanaman pakcoy (Taufiq et al 2020), sedangkan Adhikari et al (2020) melaporkan perlakuan BPS Enterobacter ludwigii dan silika dapat meningkatkan pertumbuhan tanaman padi karena menghasilkan hormon IAA serta giberelin. Menurut Marschner (2012) peningkatan diameter batang disebabkan silika pada dinding sel primer mengikat pektin dan polifenol sehingga meningkatkan elastisitas sel selama pembesaran organ.…”

Pengaruh Silika (Si) pada Arang Sekam Padi sebagai Adsorben terhadap Tanaman Holtikultura

“…Silika yang membantu dalam menyerap unsur hara membentuk silikat (Si(OH)4) oleh tanamam, sehingga meningkatkan aktivitas enzim antioksidan selama salinitas. Silika yang terdapat pada arang sekam padi membantu dalam menghambat senyawa oksidatif yang menyebabkan salinitas serta dapat meningkatkan enzim antioksidan yang membantu pertumbuhan tanaman secara maksimal (Taufiq et al, 2020).…”

Modification of The Synthesis of Silica from Litter Ori Bambusa (Bambusa blumeana) Leaves Using Sodium and Potassium With The Hydrothermal Sol-Gel Method As Agricultural Fertilizer

“…Silika diperlukan tanaman untuk meningkatkan pertumbuhan dan menjaga tanaman dari serangan hama penyakit, terutama tanaman famili graminae dan tanaman akumulator silika. Silika meningkatkan hasil biji kedelai pada tanah salin (Taufiq et al, 2020). Silika mampu menekan perkembangan penyakit hawar pelepah daun padi., karena silika meningkatkan kandungan senyawa fenolik dan ketebalan epidermis daun padi (Suharti et al, 2021).…”
