Get PDFTitle : Study of Paddy Soil Makro Nutrient Ca, Mg, and S StatusIn The Industrial Zona in Karanganyar Regency. This research was aimed to mapping Ca, Mg, S nutrient status. soil analysis was done in the soil chemistry and fertility, Department Soil science of agriculture faculty sebelas maret university on May until July 2008. This research is descriptive explorative research trough soil survey and the soil analysis was executed in laboratory. Soil sampling is based on grid sampling technique by soil aspect and administration maps. Work maps for these research used scale 1:100.000. Making of land unit maps was base on overlay between soil ordo, slope, and soil texture maps. From the overlay was resulted 9 landscape. Nutrient status rating is base on Pusat Penelitian Tanah (1980). Data analysis can be done by calculating base on laboratory analysis result, then matching with the level of each nutrient. The result of this research show that Ca nutrient status is between low and high.

Get PDFTitle : The Effect of Media Various and Concentration of Tofu Waste Fermentation Manure to Growth and Yield of Celery (Apium graveolens L.) by Hydroponic. Celery Apium graveolens L.) is a kind of leave vegetable which has a function to be an aroma addition in vegetables. This plant can grow in upland and low land. The best planting time at the first rain has fallen or the end of rain season. For to get continue yield, celery can cultured by hydroponic with use some plant media. Besides that, organic manure can used for increase plant growth and to get safety product. The aims of this research is to know the effect of the kind of media and manure concentration of tofu waste fermentation to growth and yield of celery plant that is planted in hydroponics media. The research was conducted from August until November 2007, at the Green House in Agriculture Faculty of Sebelas Maret University. The research used Complete Random Design (RAD) in factorial, it consists of two factors with three repeating. The first factor is manure concentration of tofu waste fermentation which consist of 0,00kg/l, 0,25 kg/l, 0,50 kg/l, 0,75 kg/l, 1,00 kg/l, and the concentration of 1,25 kg/l. The second factor is the kind of media which consist of sand media, husk charcoal media, and the mixing of sand and husk charcoal media. The result of the research showed that the use of sand and husk charcoal mixing produces the highest level of plant height, leave number, leave wide, wet and dry weight of straw. The treatment of 1 kg/l manure concentration given the best level of plant height, leaf number, leaf wide, root volume, as well as the weight of wet and dry weight of straw. The best combination for celery plant’s growth and development is in the combined of 1 kg/l manure concentration, with the plant media using the mixing of sand and husk charcoal.

Get PDFTitle: Kinds and doses of organic fertilizers on the yield and anthocyanin content of Roselle calyx (Hibiscus sabdariffa). A Roselle petal has fresh taste and attractive red color. In addition to containing high vitamin C which also contains the pigment anthocyanin, can be processed into several products that have high economic value. Drug efficacy from Rosella interest include lowering high blood pressure, lower levels of fat and cholesterol, blood circulation, stop cough and facilitate defecation. Increasing crop productivity can be done by providing additional nutrients through the selection of appropriate types of fertilizer, effective and efficient. Vermicompost and fermented organic fertilizer, besides containing the elements necessary macro plants also contains elements such as micro-and growth hormone auxin, cytokinin and gibberellins. The research aims to find out kind of organic fertilizer and the correct dosage to improve results rosella flower petals with high anthocyanin content. Research was done in Jumantono Village, Karanganyar. Is a field trial, RAKL nested with treatment: Various Organic Fertilizers: Bokhasi, Casting, and compost.

EFISIENSI PUPUK P DAN HASIL PADI (Oryza sativa L.) PADA SAWAH PASIR PANTAI KULONPROGO YANG DIBERI ZEOLIT
Get PDFTitle : Efficiency of P Fertilizer and Yield of Rice (Oryza sativa L.) at Sandy Soil Paddy Field Kulonprogo that Added Zeolite. The aim of this research were to study the effect of Zeolite to the efficiency of P fertilizer at Sandy Soil Paddy Field Kulonprogo and to know the rate of P fertilizer that gives the highest yield of rice (Oryza sativa L.) . This research was conducted at Krembangan, Panjatan, Kulonprogo from October 2006 to January 2007. This field experiment was arranged in Split Plot Design. Zeolite as a main plot consists of no Zeolite and 750 kgha-1 Zeolite. P fertilizer as sub plot consist of five levels of P fertilizer, i.e. 0, 20, 40, 60, 80 kg SP 36 ha-1. Each treatment was replicated three times so there are 30 plot treatments. Data were analyzed with F test, Kruskal-Wallis Test, DMRT and Correlation test. There is no interaction effect of P fertilizer and Zeolite to P uptake and Physiological Efficiency. Added 750 kg ha-1 Zeolite can increase P uptake 3.04 g/plant and increase efficiency of P fertilizer up to 62.99% in comparison with control. P Fertilizer has significant effect on total tiller number, weight of rice, weight of 1,000 seeds and percentage of rice empty. Until dosage that used in the experiment, response to P fertilizer is linier. P fertilizer 80 kg ha-1 gives the highest rice yield (6.12 kg/7 m2).

INOKULASI JAMUR PENGOKSIDASI BELERANG PADA PUPUK FOSFAT ALAM UNTUK MENINGKATKAN FOSFAT DAN SULFAT TERSEDIA BAGI TANAMAN
Get PDFTitle : The Inoculation of Sulfur Oxidizing Fungi on Phosphate Rocks Fertilizer to Increase Their Available Phosphate and Sulfate. Phosphate rocks as an alternative sources of P fertilizer are cheaper than SP-36. The main problem was their low of total and available P that must be increased to make them more effective source of P for plants. Inoculate them with S oxidizing fungi will increase their available-P. The research aim was to study the potency of two S oxidizing fungi Aspergillus japonicus and Penicillium nalgiovensis to increase available-P of phosphate rocks. Experimental research done at the Lab. of Soil Biology and Lab. of Soil Chemistry and Fertility, Department of Soil Science, Faculty of Agriculture, UNS, Surakarta, at March – Mei 2008. The experiment arranged in completely randomized design with four factors i.e. the origin of elemental sulphur (from G. Welirang, East Java and from USA), the origin of phosphate rocks (Christmas Island, Ciamis and Madura), kind of inoculums fungi (A. japonicus and P. nalgiovensis) and inoculums densities (0; 106 and 107 spore/g of phosphate rock). Each treatment combinations were replicated three times. Fifty grams mixture of phosphate rocks, cassava solid waste, tapioca and rice bran was poured in 250 ml Erlenmeyer, sterilized with autoclave at 121 oC for 30 minutes, three times alternately in 5 days, then inoculated with fungus spores and incubated at field capacity in room temperature for 3 months. Samples were taken at 1, 2 and 3 months after incubation time for analysis of water soluble-P, soluble sulphate, pH and total fungus. Data analyzed statistically with F test and Duncan Multiple Range Test at 5% of level significance. The result show that the two of S oxidizing fungi Aspergillus japonicus and Penicillium nalgiovensis were be able to increases available-P of phosphate rocks, as well as soluble sulphate more than 200 % of control treatment. Penicillium nalgiovensis was more effective than Aspergillus japonicus. As P sources, phosphate rock from Christmas Island was better than from Ciamis and Madura, while elemental S imported from USA was better than local So from G. Welirang. The increase of inoculums densities and length of incubation times increase soluble P and sulphate.
