Abstract

Hasil jagung manis di Indonesia per hektarnya masih rendah. Untuk mendapatkan hasil yang maksimal, maka selain pupuk anorganik, tanaman jagung manis membutuhkan pupuk organik. Salah satu sumber pupuk organik adalah pupuk kandang kambing karena kambing merupakan bagian integral dari sistem usahatani yang diterapkan di pedesaan. Kandungan hara yang rendah dari pupuk kandang kambing menyebabkan kebutuhan per hektarnya menjadi sangat banyak dan kesulitan dalam penggadaannya. Untuk itu perlu dilakukan pengkayaan dengan menggunakan batuan fosfat, dan zeolit.  Sementara itu, nilai estetika pupuk organik diatasi dengan membentuk pupuk granul. Percobaan pengujiaan efektivitas pupuk organik di lapangan dengan menggunakan Rancangan Acak Kelompok (RAK) faktor tunggal dan diulang 3 kali. Hasil penelitian menunjukkan bahwa pengkayaan pupuk kandang kambing dengan BFA atau Zeolit dapat meningkat nilai pH, kadar C-organik dan bahan organik tanah. Zeolit meningkatkan pertumbuhan tanaman Jagung Manis pada parameter tinggi tanaman dan jumlah daun, sedangkan BFA meningkatkan diameter daun. Takaran Zeolit 4,5% dapat menghasilkan berat dan panjang tongkol paling tinggi dibandingkan perlakuan lainnya. Kata kunci: BFA, Jagung manis, pupuk organik, zeolite.

Abstract

The high soil acidity and low nutrient content in the peatland may inhibit the growth and yield of shallot and result low productivity. As consequence, the use of peat as a growing medium needs soil fertility improvement. One alternative to improve soil fertility, growth and yield of shallot is by applying coastal sediment and foliar seaweed extract which are easy to obtain and relatively inexpensive in West Kalimantan. This study aimed to investigate soil chemical properties, growth and yield of some shallot variety after the application of coastal sediment and foliar seaweed extract (Eucheuma cottonii). A field trial was carried out through the wet period of 2014 in West Kalimantan, Indonesia. The foliar seaweed extract was applied as the foliar fertilizer (0 and 3%), meanwhile the addition of coastal sediment was done at doses of 0 and 40 t/ha. The application of coastal sediment of 40 t/ha improved some chemical properties i.e. pH and the availability of K, Ca, Mg and Na of peat soil. The combination of foliar seaweed extract with 3% and 40 t/ha of coastal sediment increased growth and yield of all shallot variety in peatland compared to using foliar seaweed extract or coastal sediment only.

Abstract

Effect of Coated Urea with Humic-Calcium on Transformation of Nitrogen in Coastal Sandy Soil: A Soil Column Method (Sulakhudin, A  Syukur, D  Shiddieq and T  Yuwono):  In coastal sandy soil, mainly nitrogen losses due to leaching resulted to low fertilizer efficiency. Slow-release N fertilizers are proposed to minimize these losses, and humic-calcium coated urea has been examined. A soil column method was used to compare the effects of coated urea with humic-calcium on transformation and leaching loss of N in coastal sandy soil. The experiment aid to compare two kind source humic substances (cow manure and peat) which mixed with calcium as coated urea on transformation, vertical distribution and leaching N in coastal sandy soil. The concentration of humic-calcium coated urea i.e.1%, 5% and 10% based on their weight.  The results showed that urea coated with humic-calcium from cow manure (UCHM) and humic-calcium from peat (UCHP) increased the N total and available N in the soil and decreased leaching loss of N from the soil column. Compare to UCHP, UCHM in all concentration showed N-nitrate higher than N-ammonium on incubation length 2, 4 and 6 weeks. The N leached from a costal sandy soil with application coated urea with UCHM ranged from 21.18% to 23.72% of the total N added as fertilizer, for coated urea with UCHP they ranged between 21.44% and 23.25%, whereas for urea (control) reach 29.48%. Leaching losses of mineral N were lower when urea coated with UCHM compared to urea coated with UCHP or urea fertilizer.  The study concluded that the UCHM is better than UCHP in decreasing N leached from coastal sandy soil.

Abstract

Effect of NPK Fertilizer and Organic Matter on P Absorption, Growth and Yield of Soybean in Psamments Bantul. The research aimed to study combination of NPK fertilizer, and manure on P absorption, growth, and yield of soybean in Psamments Bantul. The research was done in green house, Soil Physical and Chemical Laboratory, Department of Soil, Agricultural Faculty, Gadjah Mada University Yogyakarta from February to May 2007. The factorial completely randomized design with 2 factors and 3 replications used in the research with the first factor was dosage of cow manure (O) with 3 levels: O0 (0 ton/ha), O1 (20 ton/ha), and O2 (30 ton/ha). The second factor was dose of NPK fertilizer (A) with 5 levels: A0 (0 kg/ha), A1 (75 kg/ha), A2 (150 kg/ha), A3 (225 kg/ha), A4 (300 kg/ha). They were separated into two parts, forty five polybags were observed until maximal vegetative and the others were observed on harvesting to observe amount of seed per plant and seed dry weight per plant. Data analyzed using Analysis of Variance with 5% significance of level and followed with Duncan`s Multiple Range Test (DMRT). The results indicated that interaction between NPK fertilizer and manure effected significantly on P content of shoot, P absorption of shoot and root wet weight with best dose combination of 300 kg/ha of NPK fertilizer and 30 ton/ha manure. Concentration of P in 300 kg/ha NPK equivalent to 35.25 kg/ha of SP‐36 can’t increased plant growth and yield of soybean due to the dose is lower than dose of SP‐36 fertilizer that generally used by farmer. Keywords: NPK fertilizer, organic matter, soybean, psamments
