Abstract

Title : Residual Effect of Organic Fertilizer Utilization and Addition of Urea Fertilizer on The Yield of Corn on The  C-Excavation  Paddy Soil. The purposes of this study were to determine the effect of organic fertilizer residues and addition of urea fertilizers in improving soil fertility in the C excavation paddy soil and the yield of corn (Zea mays, L). Research was conducted by using completely randomized design (CRD) single factor, consisting of six treatments, as follows, P0: Control, residue treatment of : inorganic fertilizer (P1), Cow manure (P2), Bokhasi fertilizer (P3), manure and inorganic fertilizer (P4), Bokhasi and inorganic fertilizer (P5). Urea fertilizer was added a quarter of recommended dose for each treatment residue. It was given twice, except for the control treatment, and repeated 4 times, and placed randomly. Observations of soil chemical properties comprising: soil pH, C-organic, BS, CEC and the N-total crop land, while parameters of the plants, including components of the growth and yield of corn, were also observed. The results showed that the residue of organic fertilizer and the addition of urea fertilizer were able to increase the fertility of the C-excavation paddy soil. It has been proved by the growth and yield of corn were increased, such as plant height, fresh and dry weight of plant, weight and girth of the highest cob. Residual treatment obtained from the treatment of organic and inorganic fertilizer showed significantly different with the addition of urea fertilizer, as compared to control, however it showed not significantly different to other treatments.

Abstract

Title : The Analysis of Land Use Alternatives to Ensure Water Supply at Konaweha Watershed Southeast Sulawesi Province. Fenomena  of decreasing  water supply and increasing  water demand occurred at Konaweha watershed.   Konaweha  watershed  shed is a priority watershed  in Southeast  Sulawesi  Province due to its crucial function. Land use changes were suspected to be the cause of decreasing water supply. One effect of this condition  was maximum  discharge  increase  and minimum  discharge decrease of Konaweha River resulted in water deficit.   Research objectives were (1) to evaluate the effect of land use changes on hydrologic condition of Konaweha watershed;  (2) to evaluate the water supply and water demand as well as supply and demand water balance at Konaweha watershed,  and  (3) to  formulate  land  use  alternatives  and  management  policy  of Konaweha watershed.   This research had been conducted at Konaweha watershed for 10 months e.g. from June  2009  to March  2010.  The average  declining  of forest  width  during  1991‐1999  was  1.25 percent/year,  2001‐2005  was 0.52 percent/year  and 2006‐2011  was 0.90 percent/year.  In the same time the availability of minimum discharge as a water supply was decrease. There was no deficit on annual water supply until 2050 but monthly distribution  of hydrograph  caused water deficit in September started from 2016.  Proportion of maintenance  cost for watershed function at  Kendari  Municipality  was  35  percent  while  at  the  District  of  Konawe,  South  Konawe  and Kolaka were 28 percent,  15 percent, and 22 percent  respectively  from total economic  value of water  at  Konaweha   watershed.   Forest  economic   value  including   flora  and  fauna,  carbon absorption,  option value, bequest  value and existence  value was IDR 14,974,716/hectare.  Five alternative  of  land  use  at  Konaweha  watershed  were:  (1)  Scenario  1:  30  percent  forest,  45 percent plantation, 6 percent mix garden and 1 percent bush; (2) Scenario 2: 35 percent forest, 45 percent  plantation,  5 percent  mix  garden  and  1 percent  bush;  (3)  Scenario  3:  44  percent forest,  35  percent  plantation,  5  percent  mix  garden  and  1  percent  bush;  (4)  Scenario  4:  34 percent forest, 45 percent plantation, 7 percent mix garden and 1 percent bush; and (5) Scenario 5: 40 percent forest, 35 percent plantation, 5 percent mix garden and 2 percent bush. Scenario 4 were  not  appropriate   while  scenario  1,  2,  3  and  5  were  appropriate  to  applied  in  upper Konaweha  watershed.  Scenario 3 with a minimal of 44 percent of forest was the best land use alternative.Keywords: watershed, land use change, water supply, water demand

Abstract

Study of Organic and Inorganic Acid Capabilities in Solubilize Phosphatic Rock‐P. Phosphatic rock has been used as phosphate fertilizer for along time and now being an alternative of P fertilizer. But its low solubility making them uneffective source of P for plant. Many attempt to increases their solubility has been done i.e. by acidulated it with organic and inorganic acid. Inorganic acid solubilize mineral P by acidification while organic acid by acidification and maybe chelating mechanism. The aim of this research is to study the effectivity of the two kind of acid, organic (citric acid) and inorganic acid (sulphuric acid) in solubilizing phosphatic rock‐P. Research has conducted in May – Oct 2007 at Soil Biology Laboratory, Gadjah Mada University, Yogyakarta. The experiment arranged in Completely Randomized Design with three level of sulphuric acid concentration (0.00 M, 0.02 M and 0.04 M), three level of citric acid concentration (0.00 M, 0.02 M and 0.04M) and three kind of phosphatic rock (Christmas Island, Ciamis and Madura) origin. Each of combination treatment replicated three times. A gram of each phosphatic rock was added to 50 ml of aquades in 150 ml erlenmeyer flask and shoke continuously at 200 rpm in reciprocal shaker. Water soluble‐P and pH were analysed at 0, 3, 6 and 9 day after incubation time. All data was analysed for anova at 95% level of significance and continued with DMRT if any significance differences. Research show that inorganic acid (sulphuric acid) solubilize phosphatic rock‐P stronger than organic acid, except for high content Al phosphatic rock, where the two kind of acid have equal P‐solubilizing capacity. Maybe, the high P‐solubilizing capacity of organic acid for high Al‐phosphatic rock caused by its ability in chelating Al. Keywords: Fosfat, batuan fosfat alam, asam sitrat, asam sulfat

Abstract

Title : 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. Keyword: phosphate rocks, S oxidizing fungi, soluble P and sulphate

Abstract

Title : Efficiency of P Up Take and The Yield of Rice Plant (Oryza sativa L.) with Quail Manure and Inorganic Fertilizer at Paddy Soil, Palur, Sukoharjo (Season II). This research was conducted on January-August 2008. Used Randomized Completely Block Design (RCBD) that arranged in factorial with two factors. The first factor was 3 levels of inorganic fertilizer dosage i.e.: without inorganic fertilizer (A1), urea dosage 150 kg.ha-1, SP-36 dosage 75 kg.ha-1, KCl dosage 50 kg.ha-1, and ZA dosage 50 kg.ha-1 (A2), urea dosage 300 kg.ha-1, SP-36 dosage 150 kg.ha-1, KCl dosage 100 kg.ha-1, and ZA dosage 100 kg.ha-1 (A3). And second factor were 3 levels of quail manure dosage i.e.: without quail manure (O1), quail manure dosage 3 Mg.ha-1 (O2); quail manure dosage 6 Mg.ha-1 (O3). Statistical analysis that used was F test or Kruskal-Wallis test, Duncan Multiple Range (DMR) test at 5% in level, and Correlation test. The research result showed that the highest P uptake efficiency, agronomy efficiency, and the grain dry weight was achieved on 50% of inorganic fertilizer recommendation dosage (urea dosage 150 kg.ha-1, SP-36 dosage 75 kg.ha-1, KCl dosage 50 kg.ha-1, and ZA dosage 50 kg.ha-1) and 6 Mg.ha-1of quail manure treatment (A2O3) in mount of 38.83%, 30.40%, and 6.22 Mg.ha-1 respectively. P uptake efficiency in that treatment was increased as much 13.83% than the same treatment in session I. Generally, the grain dry weight on season II lower than season I. The significant decrease in mount of 2,33 Mg/ha-1 found on treatment of inorganic fertilizer present in 50% of recommendation dosage (urea dosage 150 kg.ha-1, SP-36 dosage 75 kg.ha-1, KCl dosage 50 kg. ha-1, and ZA dosage 50 kg.ha-1) and 3 Mg.ha-1 of quail manure treatment (A2O2).

Abstract

Title : The Balance of Organic and Inorganic Fertilizer on the Carrot Field (Daucus carota L.) at Andisols Tawangmangu. This experiment research was conducted on September – December 2007 in Blumbang, Sub district Tawangmangu, Karanganyar. The aim of this research was to know the effect of balance organic fertilizer and inorganic fertilizer to the carrot quality in Andisols, Tawangmangu. This experiment used RCBD (Randomized Complete Block Design) with organic fertilizer factor (0%, 50% and 100% organic fertilizer) and inorganic fertilizer factor (0%, 50% and 100% inorganic fertilizer). Statistical analysis for the influence of the treatment was variant analysis with F-test and Kruskal-Wallis test. Duncan Multiple Range Test (DMRT) was used to compare inter-treatment and for finding out of the relation inter-variable it was used correlation test. The result shows that the balance of organic and inorganic fertilizer have significant influence to the water content of carrot, the weight of carrot, the weight of dried carrot plant and the plant’s height, and have not significant influence to the carotene, carrot’s diameter, and carrot’s length. The lower water content of carrot was shown by the treatment of 100% organic fertilizer and 50% inorganic fertilizer. The treatment of 100% organic fertilizer and 100% inorganic fertilizer give the highest plant height and the weight of carrot per plant. To the soil, the balance of organic and inorganic fertilizer has significant influence to the total N of soil and to the available N of soil. It has not significant influence to the total P of soil and available P of soil, total K of soil and available K of soil. The result of correlation test showed there was positive correlation among carrot weight and water content of carrot. Keywords: Organic fertilizer, Inorganic Fertilizer, Carrot, Andisols.
