Abstract

Title : The Effect of Soil Sterilization Methods on Nutrient Status, Population of Microbiota, Potential Infectivity of Mycorrhiza and Plant Growth. The present study was aimed at elucidating the effectivity of soil sterilization methods and the effect on nutrient status, population of microbiota, potential infectivity of Vesicular-Arbuscular Mycorrhiza (VAM) and plant growth. The experimental design was Completely Randomized Design with single factor treatment. Inceptisol with VAM propagules was used for the experiment. The treatment of soil sterilization methods consisted of 8 levels with 4 replications: P1 (control, no sterilization), P2 (oven sterilization), P3 (autoclave sterilization), P4 (steam sterilization), P5 (methyl bromide sterilization), P6 (formaldehyde sterilization with cover), P7 (formaldehyde sterilization no cover), and P8 (burning sterilization). Data analyzed using Analysis of Variance and followed with Duncan’s Multiple Range Test (DMRT) with 5% of significance level. The results showed that the effectivity of total sterilization (to kill bacteria, fungi and actinomycetes) was demonstrated by burning, autoclave and steam sterilizations. The effectivity of selective sterilization (to only kill fungi) was demonstrated by formaldehyde sterilization with cover. Soil sterilization methods affected soil nutrient status with a variety of nutrients and intensities. Soil sterilization treatments affected the plant growth of soybeans. The plant growth was better in control. The exception was observed for autoclave sterilization which increased plant growth. The potential infectivity of VAM and nodulation were suppressed totally by burning, autoclave and steam sterilizations, followed by formaldehyde sterilizations with and without cover. Keywords: effectivity, nutrient status, plant growth, potential infectivity of Mycorrhiza, soil sterilization method

Abstract

Title : Hydrology of Land Site: The Changing of Land Cover and Water Absorption Level. The movement of water to the soil is called infiltration process. The process can be understood by infiltration model which developed by Phillips in 1960’s (I = st-0.5 + Kt). Phillips’s models can be explained as a function of time and are determined by soil sorptivity and hydraulic conductivity. Study of sorptivity and conductivity parameters on Teak land cover are to get more information about cumulative infiltration that accure during several times and coefficient of water absorption reference (Zref) in many kinds of land cover. Zref is the real soil potential for water moving and determines the soil macropores and reflects the water absorption ability. Coefficient of water absorption reference (Zref) with coefficient of water absorption (Z) from RAINS model (I = (Z Cos α/(1-λ)) P(1-λ)) can be used to estimate land cover index by the ratio of coefficient of water absorption and coefficient of water absorption reference, indirectly, show the function of land cover on certain area. The changing of land cover from Teak to agroforestry Teak+Soybean and monoculture system (Soybean and Maize) increase land cover index as big as 15% and 70%, respectively. On the other hand, the changing to agroforestry Teak+Maize decrease land cover index as big as 3.4%. The estimation of coefficient of water absorption reflects the function of land cover as the main point to get the ability of water soil movement. Keywords: Hydrology, Land Cover, Water Absorption Level

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.

Abstract

Title : Rice-field Cultivation Continuously was Accelerated Soil Weathering. This research was aimed to find out the existence of soil acceleration development indication as the result of the cultivation which was done continuously and for a long period. This research was done by analyzing soil samples which were taken from non-rice-field soil and cultivated soil which had been used for 20 years, 30 years, and 40 years in cultivation intensity once a year, twice a year and three times a year. Those analyzed soils had the same primary substances. The sand and clay content in the soil was chosen as the indicator of the soil weathering acceleration because of rice-field cultivation. From the data gathered, it was analyzed the connection with the cultivation length and cultivation pattern through the similarities of correlation and regression. The research result showed that: soil which was used continuously and for a long period would tend to decrease the sand content but increase the clay content in the soil. The increase of clay and the decrease of sand in the soil indicated the high soil weathering intensity which would fasten the soil development. Therefore, it is suggested that it is not needed to do puddling phase while land preparation phase, because puddling tend to mineral weathering, and if it is possible cultivation by no tillage soil system could be done. Keywords: sand and clay content in the soil, rice-field cultivation, and soil development

Abstract

Title : “Soil Suppresiveness” to Basal Plate Rot (Fusarium oxysporum  f. sp. cepae) of Garlic in Tawangmangu, Karanganyar. Since planting season in 2000, basal plate rot (Fusarium oxysporum f. sp. cepae) has been an important disease on garlic in Tawangmangu, Karanganyar, Central Java. More than 92 % of the garlic lands have been contaminated by the pathogen. However, there are some lands showing very mild disease incidence. The contaminated soil, in which the disease does not develop, is called suppressive soil. The phenomenon is interesting to investigate for understanding the occurrence of endemic of basal plate rot on the garlic in Tawangmangu and for developing control of the disease. The analysis results indicated that the suppressiveness of the soil was related to physical, chemical, and biological properties of the soil. Keywords: suppressive soil, Fusarium oxysporum f. sp. cepae, garlic
