Get PDFTitle : Effect of Bio-Natural Fertilizer on Phosphorus Uptake and Growth of Peanut in Alfisols, Entisols, and Vertisols. Development of bio-natural fertilizer was needed to overcome the scarcity of fertilizer in Indonesia, the deficiency of soil nutrient, and low efficiency of fertilizer use. The research purposed to study the effect of bio-natural fertilizer formula and find out of best formula on P uptake and growth of peanuts in various soils ordo. The experiment used a completely randomized design with three factors. The first factor was bio-natural fertilizer P1 (vermicompost 100% without enrichment material, without microbial inoculums), P2 (vermicompost 66,67%, enrichment material 33,33% and microbial inoculum of NPKS with proportion of 2:2:1:1), and P3 (vermicompost 33,33%, enrichment material 66,67% and microbial inoculum of NPKS with proportion of 2:2:1:1). The second factor was peanut varieties, Elephant and Rabbit varieties. The third factor was soil ordo, Alfisols, Entisols, and Vertisols. The variables observed were av-P, P uptake, shoot dry weight, soil pH, population of P-solubilizing fungi, plant height, and shoot fresh weight. Data was analyzed by F test at 95% level confidence. The results showed that formula of bio-natural fertilizer influence significantly on P uptake and growth of peanuts in various soils. The formula of bio-natural fertilizer P2 is the best formula to increased P uptake of peanut on Alfisols, Entisol, and Vertisol, as well as for highest peanut growth on Alfisols.Pengembangan pupuk alami bermikroba diperlukan untuk mengatasi kelangkaan pupuk di Indonesia, kekahatan unsur hara, dan efisiensi pemupukan yang rendah. Penelitian bertujuan untuk mengetahui pengaruh formula pupuk alami bermikroba dan formula pupuk terbaik terhadap serapan P dan pertumbuhan kacang tanah pada berbagai macam tanah. Percobaan menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 3 faktor. Faktor pertama berupa formula pupuk alami bermikroba, yaitu P1 (vermikompos 100% tanpa bahan pengaya, tanpa inokulum mikrobia), P2 (vermikompos 66,67%, bahan pengaya 33,33% dan inokulum mikrobia fungsional NPKS dengan perbandingan 2:2:1:1), dan P3 (vermikompos 33,33%, bahan pengaya 66,67% dan inokulum mikrobia fungsional NPKS dengan perbandingan 2:2:1:1). Faktor kedua berupa varietas kacang tanah, yaitu Gajah dan Kelinci. Faktor ketiga berupa ordo tanah, yaitu Alfisols, Entisols, dan Vertisols. Variabel yang diamati meliputi P tersedia, serapan P, berat kering tanaman, pH tanah, populasi FPF, tinggi tanaman, dan berat segar tanaman. Data yang diperoleh dianalisis menggunakan uji F dan uji jarak berganda Duncan dengan taraf kepercayaan 95%. Hasil penelitian menunjukkan formula pupuk alami bermikroba berpengaruh terhadap pertumbuhan dan serapan P oleh kacang tanah pada berbagai macam tanah. Formula pupuk alami bermikroba P2 merupakan yang terbaik dalam meningkatkan serapan P oleh kacang tanah pada tanah Alfisol, Entisol, dan Vertisol, dan untuk pertumbuhan tanaman kacang tanah pada tanah Alfisol

Get PDFTitle : The Study of Land Capability on Tobacco-Based Upland Farming at Progo Hulu Sub-Watershed. The recent and also the future problems for Indonesian concerning with agricultural environment resources are land degradation and water resources restrictiveness. Agricultural technique without awareness to concerning to soil and water conservation principles on steep and high rainfall area had caused severe erosion and land degradation at upland area of Progo Hulu sub-watershed. Land Degradation that promoted by erosion at Progo Hulu sub-watershed contributed negative effects at on-site and out-site area. The land capability analysis shows that tobacco-based farming system at Progo Hulu sub watershed dominated by class IV (3,624.93 ha; 49.00%), followed with class VI (2,488.82 ha; 33.64%), class III (697.99 ha; 9.43%), class V (450.73 ha; 6.09%), and class VII (136.06 ha; 1.84%). The main resistance factors are slope and erosion for class III; erosion, slope and surface rocks for class VI; and slope for class VII.

Get PDFTitle : Fertilizing Time Effect of Urea in Dual System Azolla‐Rice Paddy to Soil Capital Nitrogen and Rice Yield on Entisol. The purposed of research was to study the effect of urea use in dual system azolla‐rice paddy to soil capital nitrogen and rice yield on Entisol. Research was conducted on rice paddy field at Colomadu, Karanganyar district, Central Java. The experiment arranged in single factor randomized completely block design (RCBD), with eight treatments says D1 (azolla + 100 kg urea /ha at 0 day after planting‐dap), D2 (azolla + 100 kg urea /ha at 30 dap), D3 (azolla + 100 kg urea /ha at 60 dap), D4 (azolla + 50 kg urea /ha at 0 and 30 dap), D5 (azolla + 50 kg urea /ha at 30 and 60 dap), D6 (azolla + 50 kg urea /ha at 0 and 60 dap), D7 (control treatment ‐ without azolla nor NPK fertilizer), and D8 (lokal farmer treatment ‐ 250 kg urea /ha split three times, 50 kg/ha at 0 dap, 100 kg/ha at 30 dap and 100 kg/ha at 60 dap). Azolla inoculums spreaded 7 dap at rates 500 g/m2. Variables observed were soil capital nitrogen, soil total‐N, tissue total‐N, soil organic matter content and rice yield. Data taken was analyzed with anova and followed with Duncan Multiple Range Test (DMRT) at 5 % level of significant. The results show that the use of urea in dual system azolla‐rice paddy increase soil capital nitrogen, soil total‐N, tissue total‐N, soil organic matter content and rice yield at Entisol. The highest soil capital nitrogen (0,953 kg/ha) and rice yield (8 ton/ha) were taken from the treatment of D8 and D3 respectively.Keywords: azolla‐rice paddy, rice yield, soil capital nitrogen, UreaThe purposed of research was to study the effect of urea use in dual system azolla‐rice paddy to soil capital nitrogen and rice yield on Entisol.

Get PDFTitle : Diversity and Ecological Services of Epigeic Macrofauna in Carrot Crop (Daucus carota L.) with Some Proportions of Organic and Inorganic Fertilizers. Recently ecological services by macrofauna diversity to sustainable production function of agroecosystem got a lot of attention. Epigeic macrofauna is diverse of macrofaunas which their life and activities are on the land surface, act as decomposer, litter transformer, and`predator, so they are important to keep ecosystem stability. Inorganic fertilizer usage continually on carrot crop without organic fertilizer can reduce soil macrofauna diversity. Improvement can be done by the use of organic and inorganic fertilizer equally. The aim of this research was to measure epigeic macrofauna diversity and their ecological services to carrot production by giving some proportions of organic and anorganic fertilizer. The research conducted in the end of December 2007 in a farmer field in Tawangmangu. It use RAKL (Random Completly Block Design) with single factor treatment. The treatment was fertilizer type usage proportion of organic and inorganic fertilizer. They were composed of 9 proporsition composition as follows: control, 50% inorganic fertilizer, 100% inorganic fertilizer, 50% organic fertilizer, 50% organic fertilizer added by 50% inorganic fertilizer, 50% organic fertilizer added by 100% inorganic fertilizer, 100% organic fertilizer, 100% organic fertilizer added by 50% inorganic fertilizer, 100% organic fertilizer added by 100% inorganic fertilizer. 100% inorganic fertilizer were composed of Urea 150 kg ha-1, SP 36 200 kg ha-1, and KCL 100 kg ha-1. 100% dosage organic fertilizer was 20 tons ha-1. To recognize the treatment effect is done by F test and close relationship among variables tested by corelation analysis. The result showed that organic and inorganic fertilizer proportion didn’t significant to diversity, population dencity and biomass epigeic macrofauna, but affected to β caroten content of carrot. Hymenoptera was dominant macrofauna in carrot crop. Macrofauna function to increase β caroten of carrot is indirect.

This study aims to analyze the protected areas Samin watershed which use for agriculture. Research done by interpretation of the Rupa Bumi Indonesian Map, Aerial Photos and Google Earth, continued by the field observation. From this study were concluded that the protected area with slope > 45% majority have used by agriculture, while the soil is dominated by Alfisol and Andisol,which have easily eroded and prone to landslides. Most of local protected areas (rivers basin) had disfunction and it is dominated by Entisol.The mentioned cause Samin watershed gristle of floods, dryness dan landslide disaster.
