Blocked Design

In Indonesia, Inceptisols is the largest soil order on which intensive agriculture is done. The fertility of this soil order is low, so that it is necessary to improve the soil fertility by using biofertilizers and organic matter. The objectives of this experiment were to determine the effect of a biofertilizer that contains microbe Azotobacter sp., Vermicompost and N, P, K Fertilizer on N content, the population of Azotobacter sp., and the yield of the Edamame soybeans at Inceptisols Jatinangor. A Field experiment was conducted by using Randomized Blocked Design consisted of 10 treatments and three replication. The combinations of these treatments consisted of: control (no treatment), the dose recommendation Urea 100 kg ha-1 + SP36 150 kg ha-1 + KCl 125 kg ha-1, 5 ton ha-1 vermicompost + ½ recommendation ha-1 N, P, K, 5 ton ha-1 vermicompost + 1 recommendation ha-1 N, P, K, 5 ton ha-1 vermicompost + 1½ recommendation ha-1 N, P, K, 10 ton ha-1 vermicompost + ½ recommendation ha-1 N, P, K, 10 ton ha-1 vermicompost + 1 recommendation ha-1 N, P, K, 10 ton ha-1 vermicompost + 1½ recommendation ha-1 N, P, K, 5 ton ha-1 vermicompost +  ½ recommendation ha-1 N, P, K + liquid biofertilizers 5 L ha-1, 10 ton ha-1 Vermicompost + ½ recommendation ha-1 N, P, K + liquid biofertilizers 5 L ha-1.  The experimental results showed that the combined treatment of liquid biofertilizer, Vermicompost and N, P, K fertilizer enhanced the population of Azotobacter sp. and weight of soybean but did not significantly influence N uptake.

The Relationship

ABSTRACT: This study aimed to evaluate the relationship between economic indicators of soybean crops ( Glycine max L.) cultivated with Crop-Livestock Integration (CLI) or with grain production in winter, and the chemical, physical and biological attributes of the soil. It was selected ten agricultural sites in Santa Catarina to measure economic results and edaphic attributes, data was submitted to a Principal Components Analysis (PCA). Results indicated that soybean production in the summer and grain production in the winter yielded better economic results compared with summer soybean and CLI in winter. This reflects the higher productivity of the crops (9.1%) and the improved chemical, physical, and biological attributes of the soil (with the exception of organic matter content and macroporosity, which were better under the soybean system with CLI).

Glycine Max L

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.

Penelitian tentang pengaruh pemberian Pupuk organik cair (POC) asal limbah tumbuhan terhadap serapan hara N dan P serta produksi tanaman kedelai (Glycine max (L) Merrill) di lahan gambut telah dilaksanakan di kampus II Unisi Fakultas Pertanian Jl. Lintas Propinsi Parit 01, Desa Pulau Palas, Kecamatan Tembilahan Hulu, Kabupaten Indragiri Hilir Propinsi Riau. Dimulai dari bulan Agustus sampai bulan Oktober 2013. Tujuan dari penelitian ini untuk mendapatkan POC asal limbah tumbuhan yang terbaik untuk serapan hara N dan P serta produksi tanaman kedelai di lahan gambut. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktor tunggal dengan 7 perlakuan dan 4 ulangan, 2 tanaman dijadikan sampel. Perlakuan dosis POC limbah tanaman pisang dan POC limbah sayur kol yang diberikan yaitu 0 L/Ha, 200 L/Ha, 400 L/Ha dan 600 L/Ha. Parameter pengamatan yaitu : serapan hara N dan P pada fase awal generatif, tinggi tanaman, jumlah bintil akar, polong hampa, produksi perplot, berat 100 biji dan brangkasan kering. Data pengamatan dianalisis dengan sidik ragam (ANOVA) dan dilanjutkan dengan Uji Lanjut Tukey HSD pada taraf 5%. Berdasarkan penelitian yang telah dilaksanakan dapat disimpulkan bahwa pemberian POC asal limbah tumbuhan tidak berpengaruh nyata terhadap serapan hara N dan P, tinggi tanaman, jumlah bintil akar, polong hampa, brangkasan kering tetapi berpengaruh nyata terhadap produksi perplot dan berat 100 biji.

Soil Humic Acid

The Hot Water Percolation (HWP) technique for preparing soil extracts has several advantages: it is easily carried out, fast, and several parameters can be measured from the same solution. The object of this study was to examine the possible use of HWP extracts for the characterization of soil organic matter. The HPLC-SEC chromatograms, UV-VIS and fluorescence properties of the HWP extracts were studied and the results were compared with those of the International Humic Substances Society (IHSS) Soil Humic Acid (HA), IHSS Soil Fulvic Acid (FA) and IHSS Suwannee Natural Organic Matter (NOM) standards as well as their HA counterparts isolated by traditional extraction methods from the original soil samples. The DOM of the HWP solution is probably a mixture of organic materials, which have some characteristics similar to the Soil FA fractions and NOM. The HWP extracted organic material can be studied and characterized using simple techniques, like UV-VIS and fluorescence spectroscopy.
