Pemberian Pupuk Silikat dan Pupuk Kandang Terhadap Pertumbuhan, Kadar Brix, dan Hasil Tanaman Sorgum (Sorghum bicolor (L.) Moench)

Abstract

Research on the application of silicate fertilizer and manure to growth, brix level, and yield of sorghum (Sorghum bicolor (L.) Moench) was investigated to find ways to increase sorghum productivity in the dry land. The research method used was an experimental method that was set in a randomized block design consisting of 9 treatments namely control (Si0P0), without silicate and manure, 5 tones/ha (Si0P5), without silicate and manure 10 tones/ha (Si0P10), silicate 100 kg/ha and without manure (Si100P0), silicate 100 kg/ha and manure 5 tones/ha (Si100P5), silicate 100 kg/ha and manure 10 tones/ha (Si100P10), silicate 200 kg/ha and without manure (Si200P0), silicate 200 kg/ha and manure 5 tones/ha (Si200P5), and silicate 200 kg/ha and manure 10 tones/ha (Si200P10). Each treatment was replicated 3 times and the size of the plot was 6x6 m2. The results indicated that the application of silicate fertilizer and manure could significantly increase yield and brix levels. Application of silicate fertilizer of 200 kg/ha and manure 5 tonnes/ha gave higher results for the production of sorghum was 6056 kg/ha. However, the growth of sorghum was not affected significantly to the growth of sorghum plants.

The Role of Biochar and Combination of Inorganic Fertilizers and Biological Fertilizers in Increasing Yield and Levels of Brix Sorghum (Sorghum bicolor (L.) Moench) in Dry Land

“…Reduction of phosphatase activity provides a greater supply of essential high energy required for optimal sugar growth and production. This is in line with the research results of Apliza et al (2020), who concluded that the addition of Si fertilizer could significantly increase the yield and brix content of sorghum.…”

Efisiensi Pupuk Nitrogen Dan Pertumbuhan Sorgum Pada Tanah Ultisol Dengan Pemanfaatan Kompos Baglog Jamur

“…Meskipun pada fase awal pertumbuhan, pemberian kompos baglog tidak menujukkan pengaruhnya, namun pada fase generatif pengaruhnya terlihat jelas. Menurut Apliza et al (2020), pupuk kadang mengalami mineralisasi menjadi bentuk hara yang dapat diserap tanaman memerlukan waktu yang cukup lama sehingga tanaman sorgum baru menunjukkan respons pada saat memasuki fase generatif. Pengaruh kompos baglog terbaik (4,55 g) didapatkan dari dosis 30 ton/ha.…”

Produktivitas dan Kualitas Galur Mutan Sorgum Bmr Pada Aplikasi Pupuk Organik Kelompok Tani Sumber Sari Desa Aunupe Sebagai Pakan Ternak

“…Pengukuran dilakukan pada saat panen adalah hasil hijauan segar tanaman sorgum BMR. Semua sampel sorgum BMR yang sudah dipanen (batang dan daun) kemudian dimasukkan dalam kantong koran (koran sudah diketahui beratnya) sehingga diketahui berat segarnya [2]. Tahap pengambilan data produktivitas tanaman sorgum meliputi pengukuran tinggi tanaman, diameter batang, rasio daun/batang, biomassa segar individu, kadar gula (brix), kandungan bahan kering dan produksi bahan kering (ton/ha).…”

“…Nilai brix meningkat pada fase pembungaan hingga fase matang fisiologis yang diduga terjadi karena penurunan kandungan air di batang. Selain itu, [11] menambahkan bahwa semakin mendekati umur panen maka kadar gula akan semakin meningkat, dan mengalami penurunan kadar gula setelah melewati masa umur panen akibat aktivitas enzim envertase pada tanaman.…”
