Abstract

Penelitian ini bertujuan untuk mengevaluasi kesesuaian lahan untuk tanaman kopi arabika, kentang, kubis dan jeruk Di Kecamatan Harian Kabupaten Samosir. Diperoleh 9 (sembilan) SPL (satuan peta lahan) yang ditentukan berdasarkan peta jenis tanah, peta kemiringan lereng dan peta ketinggian tempat yang dihasilkan dari peta topografi dengan skala 1 : 50.000, kemudian dilakukan overlay. Penilaian kelas kesesuaian lahan berdasarkan kriteria Staf Pusat Penelitian Tanah Bogor Tahun 1993 dan metode evaluasi lahan adalah metode limit berdasarkan Djaenuddin, 2011.

Abstract

The objective of this study is to determine the effect of SP-36 fertilizer application and cow manure on the availability and P uptake on Inceptisol taken from Kwala Bekala. This research conducted in gauze house, Soil Fertility Chemical Laboratory, Faculty of Agriculture, University of North Sumatra and PT. Nusa Pusaka Kencana & QC Analytical Laboratory (Asian Agri Group). This study used Randomized Block Design which consist of two factors with three replications Factor I: SP-36 fertilizer (P) with 4 levels dose (ppm / 10 kg BTKO) ie: P0 (0), P1 (100), P2 (200), P3 (300) and factor II: cow manure (S) with 4 levels dose (g / 10 kg BTKO), namely: S0 (0), S1 (50), S2 (100) and S3 (150). The results showed that SP-36 fertilizer application significantly increased soil available P and P-plant uptake. Cow manure significantly increased P-plant uptake. The interaction between SP-36 fertilizer and cow manure significantly increased P-plant uptake. The best treatment was the application 300 ppm P2O5 SP-36 and cow manure 20 tons/ha

Abstract

Pemanfaatan sludge pabrik pengolahan kelapa sawit masih belum optimal, oleh sebab itu perlu pengkajian pemanfaatan sludge sebagai alternatif penyediaan unsur hara di tanah Ultisol. Penelitian dilaksanakan selama 4 bulan dimulai pada bulan November 2015 hingga Maret 2016 di rumah kasa Fakultas Pertanian Universitas Sumatera Utara dan analisis tanah serta tanaman dilakukan di Laboratorium Riset dan Teknologi Fakultas Pertanian USU. Penelitian ini menggunakan rancangan acak kelompok non faktorial dengan tanpa perlakuan (Z0), 21,25 g sludge/pot (Z1), 42,50 g sludge/pot (Z2), 63,275 g sludge/pot (Z3), 85,00 g sludge/pot (Z4), 106,25 g sludge/pot (Z5), 127,50 g sludge/pot (Z6), 148,75 g sludge/pot (Z7), dan 3 ulangan. Hasil penelitian menunjukkan pemberian sludge berpengaruh nyata dalam meningkatkan unsur hara dan pertumbuhan tanaman jagung di tanah Ultisol yaitu : pH tanah, C-organik, P tersedia, tinggi tanaman, jumlah daun, diameter batang, berat kering tajuk dan serapan P tanaman. Akan tetapi tidak berpengaruh nyata dalam meningkatkan N total, K tukar, dan KTK tanah Ultisol. Kata Kunci : sludge, Ultisol,unsur hara

Abstract

Penelitian bertujuan untuk mengetahui kandungan logam berat Pb daun kol dan buah tomat di tiga Kecamatan Kabupaten Karo yaitu Kecamatan Simpang Empat, Kabanjahe dan Tiga Panah. Analisis tanaman dilakukan di Laboratorium Pusat Penelitian Kelapa Sawit (PPKS) Medan, pada bulan April - Mei 2016, menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan 3 ulangan. Faktor pertama jenis tanaman yaitu: daun kol dan kulit buah tomat, faktor kedua jarak dari jalan raya yaitu 5 m dan 10 m serta faktor ketiga adalah pencucian yaitu tanpa dicuci dan dicuci dengan air mengalir. Parameter yang diamati kandungan logam berat Pb pada daun tanaman kol dan kulit buah tanaman tomat. Hasil penelitian menunjukkan bahwa jenis tanaman, jarak dari jalan raya dan pencucian berpengaruh terhadap kadar Pb. Kadar Pb daun kol pada jarak 5 m dan 10 m tanpa pencucian masing-masing 6,19 ppm dan 4,79 ppm dan dengan pencucian 4,48 ppm dan 3,86 ppm. Sedangkan kadar Pb pada buah tomat pada jarak 5 m dan 10 m tanpa pencucian 4,01 ppm dan 3,10 ppm dan dengan pencucian 3,08 ppm dan 2,26 ppm.

Abstract

The research was aimed to know that accumulation of lead in soil and mustard due to urban waste compost application. The researh was held in gauze house and analyzed in Balai Pengkajian Teknologi Pertanian (BPTP) Laboratory, North Sumatera in April -July 2016. The research used randomized block design factorial with two treatment factors those are the depth of layers of urban waste compost with 3 level of treatment ; S1 (upper layer), S2 (middle layer), S3 (bottom layer) and growing media composition with 5 level of treatment ; M0 (100% soil), M1 (25% compots + 75% soil), M2 (50% compost and 50% soil), M3 (75% compost + 25% soil), M4 (100% compost) with 3 replications. The result showed that giving25% urban waste compost can increase of production of mustard, soil pH, soil C-organic, total Pbsoil and Pb in plants and it’s value exceeds the threshold. The depth of layers of urban waste compost significant effect on total Pb soil and Pb in plants and it’s value exceeds the threshold. Interaction amount of compost and the depth of layers of urban waste compost were not significant increased of production of mustard, but significant increased of soil pH, soil C-organic, total Pbsoil and Pb in plants.

Abstract

The research was conducted at rice field in Medan Tuntungan which about ± 25 metres above sea level, begun from March until June 2017 using completly randomized design with two factors, i.e: the number of seeds (1,2,3) and plant population based on modified jajar legowo planting system (conventional planting system with population of 48 clumps per plot, jajar legowo planting system with population of  60 clumps per plot, jajar legowo planting system with population of 114 clumps per plot, jajar legowo planting system with population of 154 clumps per plot, jajar legowo planting system with population of 190 clumps per plot). The results showed that 1 seed of clumps with conventional planting system with population of 48 clumps per plot significantly influence the increase of rice production (Oryza sativa L.). The interaction between number of seeds dan plant population significantly increased growth but did not significantly increase rice production (Oryza sativa L.).

Abstract

The study was performed in order to investigate the influence of organic matter of  kirinyuh (Eupathorium odoratum) and that of organic matter of paitan (Tithonia diversifolia) on some soil chemical properties and maize yield on Ultisols of  Village Huta Ginjang. The experiment was in a non-factorial randomized complete block design. The treatments included control, inorganic NPK 100 %, fresh bitter bush 10 t/ha, fresh wild sunflower 10 t/ha, decayed bitter bush 10 ton/ha, decayed wild sunflower 10 ton/ha, fresh bitter bush 10 ton/ha + 50 % NPK, fresh wild sunflower 10 ton/ha + 50 % NPK, decayed bitter bush 10 ton/ha + 50 % NPK, and decayed wild sunflower 10 ton/ha + 50 % NPK. The treatments was replicated three times. The results showed that the applications of fresh bitter bush (Euphatorium odoratum), decayed bitter bush, fresh bitter bush + 50 % NPK and fresh wild sunflower (Tithonia diversifolia), decayed wild sunflower, fresh wild sunflower + 50 % NPK significantly increased soil pH, N-total of soil, exchangeable K of soil, fresh fruit weight, and the 1,000 maize seed weight. However, the application of decayed wild sunflower combined with NPK was the most appropriate one since it generated the extraordinary value on parameters: soil pH, exchangeable K, fresh fruit weight and the 1,000 maize seed weight with their values in turn: 5,41; 2,53 me/100g; 357,33 g/plot dan 303,33 g/plot.   Keywords :kirinyuh, maize production, organic matter, tithonia, Ultisol
