Abstract

The Variability of Soil Macrofauna on Palawija Cropping of Dry Land in The Rainfall Season. The variability of Soil macrofauna is the one of biological natural resources that very useful for the environment. Their existence affected by biotic and abiotic factors around them. Soil macrofauna variability that exists on the dry land in palawija cropping will be different from the vegetation of forest. The aim of this research is to know the effect of the palawija cropping to soil macrofauna variability on the dry land in the rainfall season. The research was conducted on November 2006‐April 2007. This research is descriptive explorative that has quantitative and qualitative ones with the field survey and laboratory analysis approach. The technique of determination sampling location based on purposive sampling system. The taking of sample has been done in 3 locations under 3 palawija cropping (maize, peanut, and soybean) as much 3 times replication in the rainfall times (December 2006‐Februari 2007). The result shows that palawija cropping influences non significantly to the macrofauna variability on the soil surface, soil macrofauna variability under soil surface and environment variables that have been observed unless to bulk density (influences significantly). The highest macrofauna variability on the soil surface occurs in maize cropping. Whether under soil surface macrofauna variability occurs in peanut cropping. There were five Ordos of macrofauna on the soil surface that found in maize cropping, Hymenoptera, Araneida, Orthoptera, Diplura, and Collembola (mesofauna). Ten Ordos of macrofauna under soil surface that found under peanut cropping were Hymenoptera, Isoptera, Oligochaeta, Diptera, Homoptera, Hemiptera, Orthoptera, Araneida, Lepidoptera and Collembola (mesofauna). It was found that dominancy of the ordo of macrofauna on the soil surface from ordo Hymenoptera in maize cropping and ordo Orthoptera in peanut and soybean cropping. The dominancy of soil macrofauna under soil surface was from ordo Hymenoptera and was found under maize and peanut cropping and Oligochaeta in soybean cropping. There were positive and negative functions of soil macrofauna. The positive ones are as a predator and decomposer of organic material. Whether the negative are as virus vector and plant disease. Key word: macrofauna variability, palawija cropping, and ordo of macrofauna

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 : 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. Key words: fertilizer proportion, epigeic macrofauna,  caroten, Hymenoptera, ecological service
