Abstract

Sugarcane is proved to absorb more Si than any other nutrient from soil; therefore continuous cropping of the plant at the same soil would bring consequences of more Si and organic matter depletion. Silicon (Si) is considered a beneficial nutrient for sugarcane production. Field study was carried out in 2013-2014 at Kempleng village; Purwoasri sub district; Kediri district; East Java. The objective was to find out the effect of frequency and concentration of Si liquid fertilizer on Si and N absorptions, stem diameter and length, yield and commercial cane sugar (CCS) of sugarcane var PSBM 901. Split plot design with three replicates was employed to arrange the treatments. As main plots were frequency of spraying (one time, two times, three times, and four times with interval of 20 days started at 30 days after planting), while as sub plots were concentration of Si fertilizer (0, 15% Si, 30% Si). Results showed that interaction between frequency and concentration of Si affected on all parameters observed. Spraying of sugarcane four times with 30% Si gave highest value of cane yield, rendement, and sugar yield, i.e. 184.16 tons/ha and 8.36%, 15.37 ton/ha respectively.Keywords: sugarcane, yield, commercial cane sugar AbstrakTebu tergolong jenis tanaman akumulator unsur Si, sehingga penanaman secara terus menerus pada lahan yang sama akan berakibat semakin terkurasnya unsur Si dan menurunnya bahan organik dalam tanah. Unsur Si berperan penting terhadap pertumbuhan tebu terutama pada tanah-tanah tropis. Untuk mengetahui efektivitas pupuk Si cair pada tebu, telah dilakukan penelitian lapang pada tahun 2013-2014, yang berlokasi di Desa Kempleng, Kecamatan Purwoasri, Kabupaten Kediri, Jawa Timur. Tujuannya untuk mengetahui pengaruh frekuensi dan konsentrasi pemberian pupuk cair Si terhadap serapan Si dan N, pertumbuhan, produksi dan rendemen tebu varietas PSBM 901. Penelitian disusun dengan Rancangan Petak Terbagi dengan tiga ulangan. Sebagai petak utama adalah frekuensi penyemprotan (1 kali, 2 kali, 3 kali, 4 kali dengan interval 20 hari sekali sejak umur tebu 30 hari). Sebagai anak petak adalah konsentrasi pupuk Si (0, 15%, 30%). Hasil penelitian menunjukkan bahwa interaksi antara frekuensi penyemprotan dan konsentrasi pupuk Si berpengaruh terhadap peningkatan serapan Si dan N, diameter batang, panjang batang, produksi dan rendemen tebu. Penyemprotan pupuk Si pada tebu sebanyak 4 kali (umur 30, 50, 70 dan 90 hari) dengan konsentrasi 30% Si menghasilkan tebu dengan bobot dan rendemen tertinggi serta gula hablur, yaitu masing-masing sebesar 184,16 ton/ha dan 8,36% serta 15.37 ton/ha.Kata kunci: Tebu, Si, produksi, rendemen

Abstract

Program intensifikasi tebu dalam rangka meningkatkan produksi dan hablur dapat dilakukan dengan penambahan hara tanah melalui aplikasi pupuk.  Penelitian ini bertujuan mengevaluasi efektivitas  pupuk majemuk NPK (22% N:12% P2O5:12% K2O) berbentuk granul dan briket terhadap pertumbuhan, produktivitas, dan rendemen tebu.  Penelitian dilakukan pada bulan November 2012-Oktober 2013 di Kebun Percobaan  Kalipare, Kabupaten Malang. Perlakuan meliputi (1) 600 kg/ha NPK granul (G1), (2) 700 kg/ha NPK granul (G2), (3) 800 kg/ha NPK granul (G3), (4) 1.000 kg/ha NPK granul (G4), (5)  600 kg/ha NPK granul (G5) + 300 kg/ha Ammonium Sulfat (AS), (6) 700 kg/ha NPK granul (G6) + 300 kg/ha AS, (7) 800 kg/ha NPK granul (G7) + 300 kg/ha AS, (8) 1.000 kg/ha NPK granul (G8) + 300 kg/ha AS, (9) 600 kg/ha NPK briket (B1), (10) 700 kg/ha NPK briket (B2), (11) 800 kg/ha NPK briket (B3), (12) 1000 kg/ha NPK briket (B4), (13) 600 kg/ha NPK briket (B5) + 300 kg/ha AS, (14) 700 kg/ha NPK briket (B6) + 300 kg/ha AS, (15) 800 kg/ha NPK briket (B7) + 300 kg/ha AS, (16)  1.000 kg/ha NPK briket (B8) + 300 kg/ha AS, (17) 600 kg/ha (N15, P15, K15) + 500 kg/ha AS (pembanding/aplikasi petani). Rancangan disusun secara acak kelompok dan diulang tiga kali. Hasil penelitian menunjukkan bahwa perlakuan B8,  B6, B7, dan G8 menghasilkan pertumbuhan, produktivitas, rendemen, dan hasil hablur lebih tinggi dibanding dengan pembandingnya. Perlakuan B6 paling efisien dalam meningkatkan produktivitas (22,29 ton/ha), hasil hablur (2,03 ton/ha) dan keuntungan (Rp11.013.120,00/ha).The Influence of Granular and Briquette Compound Fertilizers on Growth, Productivity,and Sugar Content of SugarcaneIntensification program of sugarcane in order to increase production and sugar crystal can be done with the addition of soil nutrient through fertilizer application. This study aims to evaluate the effectiveness of NPK compound fertilizer (22% N:12% P2O5:12% K2O) in the form of granular and briquettes to growth, productivity, and sugar content. The research was conducted on November 2012–October 2013 at Kalipare Experiment Station, Malang. The treatments include (1) 600 kg/ha granule NPK (G1), (2) 700 kg/ha granule NPK (G2), (3) 800 kg/ha granule NPK (G3), (4) 1,000 kg/ha NPK granule (G6) + 300 kg/ha NPK granule (G5) + 300 kg/ha Ammonium Sulphate (US), (6) 700 kg/ha NPK granule (G6) + 300 kg / ha US, (7) 800 kg / ha NPK granule (G7) + 300 kg / ha US, (8) 1,000 kg / ha granule NPK (G8) + 300 kg/ha US, (9) 600 kg/ha NPK briquettes (B1), (10) 700 kg/ha NPK briquettes (B3), (12) 1.000 kg/ha NPK briquettes (B4), (13) 600 kg/ha NPK briquettes (B5) + 300 kg/ha US, (14) 700 kg/ha NPK briquette (B6) + 300 kg/ha US, (15) 800 kg/ha NPK briquette (B7) + 300 kg/ha US, (16) 1,000 kg/ha NPK briquettes (B8) + 300 kg/ha US, (17) 600 kg/ha (N15, P15, K15) + 500 kg/ha AS (famer’s application). The experiment was arranged design in randomized block design and repeated three times. The results showed that treatments B8, B6, B7, and G8 resulted in higher growth, productivity, and sugar production compared to farmer’s application.

Abstract

Improvement of cultivation technology is a part of the sugarcane intensification programs to supply the national sugar demand. Fertilization package is one component in of the of cultivation technology improvement. The research aims to obtain the information on (1) the role of Ca + Mg versus Sulfur nutrients, (2) the integration of low-dosage compound fertilizers with manure versus high-dosage compound fertilizers without manure, and (3) moderate-dosage versus very high-dosage of compound fertilizer without manure in improving productivity, sugar yield and economic benefits in sandy upland. The research was conducted in November 2012 - October 2013 at Asembagus Experimental Station, Situbondo, East Java. Four fertilizer packages was arranged in a Randomized Block Design and replicated three times. Data were analyzed by orthogonal contrast. The results showed that package of compound fertilizer containing Ca + Mg inccreased productivity (11,67%), sugar yield (15,51%) and economic benefit (293,3%) from the package of fertilizer without containing Ca + Mg with high-dosage Sulfur. Package of high-dosage compound fertilizer containing Ca + Mg without manure inccreased productivity (5.82%), sugar yield (8.26%) and economic benefit (54%) from package of low-dose fertilizer + manure. Package of very high-dosage compound fertilizer containing Ca + Mg inccreased productivity (32%), sugar yield (31,32%) and economic benefit (347,7%) from moderate-dosage fertilizer package.
