“…Yasari et al (2012), studying rice plant density and silica application, observed an increase of 11.6% in the total number of tillers and 14.2% in the number of tillers per plant, with the application of 250 kg ha -1 of pure silica. The different results in the present study may be due to the use of high silicon doses, since the dose promoting the lowest tillering (460 mg dm -3 ) is approximately twice the dose used by the previously mentioned authors.…”

A B S T R A C TThe cultivation of upland rice (Oryza sativa) in Brazil occurs mainly in the Cerrado, a region with adverse weather conditions. The use of silicon in its cultivation becomes important, since this nutrient provides higher rigidity, lower transpiration and higher resistance to dry spells in rice plants. The objective of the present study was to evaluate the effect of silicon fertilization and soil water tensions on upland rice development and yield in a Cerrado Oxisol. A 5 x 5 fractionated factorial with five soil water tensions (0, 15, 30, 45 and 60 kPa) and five silicon doses (0, 120, 240, 480 and 960 mg dm -3 ) was used, which were distributed in a randomized block design, with four replicates. Plant height, number of tillers, number of panicles, number of grains per panicle, numbers of full and empty grains and percentage of empty grains were evaluated. Silicon fertilization promotes increased tillering in rice plants at the dose of 960 mg dm , respectively. The increase in soil water tensions reduced plant height and the number of full grains, and increased the percentage of empty grains of upland rice.Adubação silicatada e tensões de água no solo no desenvolvimento e rendimento do arroz R E S U M O O cultivo de arroz (Oryza sativa) de terras altas no Brasil ocorre principalmente em área de Cerrado, região que apresenta condições climáticas adversas. A utilização do silício em seu cultivo torna-se importante de vez que este nutriente proporciona maior rigidez, menor transpiração e maior resistência a veranicos em plantas de arroz. No presente estudo, objetivou-se avaliar o efeito da adubação silicatada e tensões de água do solo no desenvolvimento e rendimento de arroz de terras altas em Latossolo Vermelho do Cerrado. Utilizou-se esquema fatorial 5 x 5 fracionado com cinco manejos de irrigação baseados nas tensões de água no solo (0, 15, 30, 45 e 60 kPa) e cinco doses de silício (0, 120, 240, 480 e 960 mg dm -3 ) as quais foram distribuídas segundo delineamento de blocos ao acaso, com quatro repetições. Foram avaliados: altura de plantas, número de perfilhos, número de panículas, número de grãos por panícula, número de grãos cheios e chochos e porcentagem de grãos chochos. Adubação silicatada promove o aumento do perfilhamento em plantas de arroz com a dose de 960 mg dm . Ocorreu um decréscimo de produção de perfilhos e número de panículas com a aplicação de silício até as doses de 460 e 490 mg dm -3 , respectivamente. O aumento das tensões de água no solo reduziu a altura e o número de grãos cheios, e aumentou a porcentagem de grãos chochos de arroz de terras altas.

“…Pemberian biosilika pada tanaman sorgum yang ditanam pada lahan kering mampu meningkatkan produksi biji sorgum antara 32% sampai 78%. Menurut Yasari et al (2012), bahwa pemberian silika meningkatkan pertumbuhan dan produksi, karena silika di dalam tanah mempengaruhi penyerapan unsur nitrogen, posfor, dan kalium bagi tanaman (Akter dan Shirin, 2012). Silika menghasilkan daun lebih keras dan tegak (Hosseini et al, 2012), sehingga efektif menerima sinar matahari untuk fotosintesis (Yasari et al, 2012) yang menyebabkan produksi menjadi meningkat.…”

Tanaman sorgum merupakan sereal yang tergolong akumulator silika, sehingga membutuhkan banyak silika dalam pertumbuhannya. Peningkatan ketersediaan silika dalam tanah dapat dilakukan dengan penambahan biosilika dari jerami padi yang diolah menjadi kompos. Penelitian bertujuan untuk menganalisis manfaat biosilika yang berasal dari kompos jerami padi terhadap pertumbuhan dan produksi tanaman sorgum yang dibudidayakan pada lahan kering. Percobaan dilaksanakan di lahan kering Desa Air Satan Kabupaten Musi Rawas dari bulan Juni sampai September 2019, menggunakan metode eksperimental dengan Rancangan Acak Kelompok non factorial yang diulang 4 kali. Biosilika yang dicobakan: B0 = tanpa biosilika, B1 = 50 kg Si ha-1, B2 = 100 kg Si ha-1, B3 = 150 kg Si ha-1, B4 = 200 kg ha-1, dan B5 = 250 kg Si ha-1. Sorgum varietas Samurai ditanam dengan jarak 25 cm x 60 cm pada petakan yang berukuran 1m x 5 m sebanyak 24 petakan dan diberi pupuk NPK (15:15:15) dengan dosis 300 kg ha-1, tanaman dipanen 110 hari setelah tanam. Peubah penelitian meliputi waktu berbunga (hst), tinggi tanaman (cm), jumlah daun (helai), produksi per ha (ton), bobot 1.000 biji (g), dan bobot biomas basah (kg). Data dianalisis dengan analisis keragaman pada taraf uji 1% dengan uji beda nyata jujur (BNJ). Kesimpulan penelitian ini menunjukkan bahwa biosilika dari kompos jerami padi sangat nyata meningkatkan pertumbuhan dan produksi tanaman sorgum. Pemberian biosilika pada tanaman sorgum di lahan kering sebanyak 250 kg ha-1 meningkatkan produksi sebesar 78%.

“…Agostinho (2016) also reported no significant increase in tiller number with foliar or soil application of Si. On the other hand, the increased tiller number of rice plant was recorded by Yasari et al (2012) and Gholami and Falah (2013).…”

Plants absorb silicon (Si) from soil solution in the form of monosilicic acid, also called orthosilicic acid (H 4 SiO 4 ). Application of organic and inorganic materials containing readily soluble Si can increase Si supply in the soil and its uptake by plant. The study aimed to evaluate the release of Si from organic and inorganic material sources and its uptake by rice plant. The released phosphorus (P) from those materials was also evaluated. The inorganic materials evaluated included fly ash, steel slag, silica gel and Japanese silica gel (JSG), while the organic materials consisted of rice husk ash (RHA), rice husk burnt (RHB), media of mushroom (MM), cacao shell biochar (cacao SB) and rice straw compost (RSC). The dynamics of Si and P were observed by periodical samplings at 7, 17, 24 and 34 days after transplanting (DAT). Tiller number and plant height were measured at 16, 21 and 36 DAT. The results showed that Si concentration in solution derived from inorganic material was highest for JSG followed by silica gel (1.107 and 0.806 mmol L -1 , respectively). The release of Si from organic material was higher for RHB and RHA (0.618 and 0.539 mmol L -1 , respectively). Cacao SB, silica gel, JSG and RHB significantly increased plant height at 36 DAT. Meanwhile, Si materials did not significantly affect the tiller number. Of the materials used, steel slag and JSG significantly affected Si uptake by rice plant.[Keywords: rice, silicate materials, silicon, silicon uptake] ABSTRAK Tanaman menyerap silikon dari larutan tanah dalam bentuk asam monosilikat, yang juga disebut asam ortosilikat (H 4 SiO4
