Abstract

Dieng is a plateau region, with an altitude about ± 2095 meters above sea level. Dieng Plateau is unique land because that has low air temperature and soil dominated Andisol and has various land slope from 0 percent until >40 percent. Therefore, Dieng Plateau is ideal land for horticultural cultivations. The serious problem in Dieng Plateau was conducted intensively conversion the forest area to the various land use system, to example for land potatoes cultivation, settlements and tourist activity. These conditions increasing hazard for the rate soil erosion. High soil erosion rate will decrease the soil fertility.This study aims to determine the level of soil fertility with indicators of soil microorganisms in a various of land use, given the high levels of soil erosion. The layout design of the research used is a Randomized Complete Block Design (RCBD). Analysis of the data used is Analysist of Variance – ANOVA (F test), Honestly Significant Analysis (5%) and Stepwise Regressiont. To determination the number of carbon biomass of microorganisms is applied with fumigation-extraction method. Fordetermination of total soil microorganisms using NA media, where as the determination of soil respiration using Verstraete method.The results showed that the land is sloping physiography (tourist land and residential) have higher fertility than high physiographic area, as a result of soil erosion. Different case for protected forests, although a high physiographic land, forests have higher fertility than the land potatos cultivation. Forest area are still natural, and its has a vegetation litter and diversity of vegetations, therefor the forest area has good barrier water runoff that carries organik material and soil salts.

Abstract

Puccinia horiana P. Henn. is the pathogen which caused of white rust on chrysanthemum. It is the most serious disease on chrysanthemum. Study on the effect of varieties, defoliation, and fungicide application against rust diseases (Puccinia horiana) was carried out under plastic house of Institute of Ornamental Crop Research at Segunung (alt. 1100 m asl) from July - November 2008, using Split-split plot design in three (3) replications. The main plot was chrysanthemum cultivar (cv. ILK.6B1, cv. Giant and cv. Cat eye); sub-plot was defoliation and sub-sub plot was application of fungicide. The results indicated that a) cv. Cat Eye, cv. ILK.6B1 (aster/Reagent) and cv. Giant were resistant, moderately resistant, and susceptible against rust caused by Puccinia horiana respectively; b) defoliation was able to reduce disease intensity of rust as much as 44 percent at the beginning, but only 3-21 percent on the further observations; c) fungicide application was able to reduce disease intensity as much as 20-49 percent; d) defoliation and fungicide application did not significantly influence the number of flowers, plant height and flower diameter.
