Abstract

The research of the effect of shading and mycorrhyza inoculations on the growth of cacao seedlings on the Red-yellow Podzolic soil and Andosol had been conducted in Microbiology laboratory of Agriculture Faculty, Gadjah Mada University, and a field experiment in Pogung, subdistrict of Sinduadi, Mlati,  Sleman, Yogyakarta. The research aimed to determine the best combination that can increase the quality of the cacao seedling. The research was conducted using a Split-split plot design, the experimen was done with three factors and three replicates. The first factor was the shading level that consisted of no shading, shading in 25%; 50% and 75%. The second factor was the type of soils (red-yellow podzolic soil and andosol),  The third factor was the mycorrhyza inoculations (no-mycorrhyza inoculation, Gigaspora margaritainoculation and Glomus manihotis inoculation). Results of this research showed that the interaction effect between the three factors wassignificant.  Interaction occurred between the shading and the soil type and also between the shading and the mycorrhyza inoculation, meanwhile each single factor had also significant effect on all variable observed.  The interaction between shading and soil significantly affected stem diameter, root dry-weight, root volume, root shoot ratio, relative growth rate (RGR), and P absorption.  The interaction between the shading and the mycorrhyza had significant influence on plant height and specific leaf weight (SLW). The shading level of 25% on the andosol soil inoculated with the Glomus manihotismycorrhyza is the best treatment for growing cacao seedlings. Keywords: Andosol, Cacao seedling, Mycorrhyza, Red-yellow Podzolic soil, Shading.

Abstract

Orange is one of important agricultural commodities with highest position in agroindustry sectors; therefore it is needed a considerable effort to develop the orange plants in a large scale.  One of technologies supporting such effort is plant propagation via tissue culture technique. The aim of this experiment was to obtain the most suitable type and concentration of cytokinins for the growth of orange. This experiment was conducted in Plant Biotechnology Laboratory, Faculty of Agriculture, Tadulako University from June to November 2014.  This experiment used a Completely Randomized Design with six treatments, namely 0.5 ppm BAP, 1.0 ppm BAP, 1.5 ppm BAP, 0.5 ppm Kinetin, 1.0 ppm Kinetin and 1.5 ppm Kinetin.  Data was analyzed using analysis of variance and differences between means of the treatments were determined by Honestly Significant Difference test at 5% level.  Results of this experiment indicated that the most suitable type and concentration of cytokinin for the growth of orange was the medium culture supplemented with 1.0 ppm BAP. In such medium composition, the quickest and the highest number of shoot formation was obtained as well as the highest number of leaf formation at 6 weeks after culture, namely 3.40 days after culture, 2.12 shoots and 5.00 leaves per explant, respectively. Keywords :  Cytokinin, In Vitro,Orange.

Abstract

This research aimed to determinefactors influencing the production of clove farmingsand their income at Ogodeide district ofTolitoli regency. This research was conducted from August to October 2015. Data wasobtainedfrom 84 clove farmers who were selected using a simple random technique. The data was processed and analyzed by using production function of Cobb-Douglass. The results showed that simultaneously, the independent variables (X) significantly influence the dependent variable (Y) and the coefficient of determination (R2) was 0.90. Based on the partial test, it is obvious that there are four variables significantly influence the cloves production including the number of productive trees (X1), the use of ZA fertilizers (X3), the use of ponska fertilizer(X4), and the labors (X5) while the age of cloves variable (X2) has no significant influence to the clove production at Ogodeide district of Tolitoli regency. The income analysis suggests that the income generated by the farmer was IDR58,102,598.98/year, in average. Keywords: Clove farming, income, production factors.

Abstract

            The study on soil formation based on toposequenceof granite parent rock at LoreLinduNational Park is a pedology study to understand specific characteristics of soil developed on graniteparent rock. The study began from October to December 2015, and conducted in three phases, namely field study, laboratory analysis, and descriptive data analysis. On the same parent material, three representative profiles were investigated, and then the chemistry, physic, and mineralogy were analyzed. The representative profile determination was based on geological map, topographical map, and general vegetation condition in field. Comparison between one profile and others used similarity index calculation. The field profiling showed that the same horizon on the three representative profiles, namely Ah, Bw, BC, C, and similarity index indicated that there are more similaritiesamongprofiles G1, G2, and G3. It islikely due to the rock formation existed in one toposequence tract of land was mutually continued, so that a part of soil of rock profile existing in the upper position was transported into the lower profile. All soil profiles began to develop on early phase characterized by dominant montmorillonite clay mineral of 2:1 type. The soils of the G1, G2, and G3 profiles are classified into Humic Cambisols according to FAO/UNESCO (1997) whereas according to PPT (1983) they are classified into Cambisols Distric and according to the Soil Taxonomy System (1998) classified into Humid Dystrudept. Keywords: Classification, Genesis, Granite, Lore Lindu, Soil, Topography.

Abstract

This research was conducted at Dungingis and Kapas Villages, Dako Pemean Sub District, Tolitoli Regency. The objective of the research is to determine the influence of production input uses and their efficiency in clove farming.  The inputs included number of productive trees, urea fertilizer, ZA fertilizer, phonska fertilizer, and labor. This research use Slovin equation in determining the number of respondents. The number of respondents was 75 clove farmers. Data was analyzed using multi linier function analysis of Cobb Douglas. The results of the research showed that the independent variables (Xi) such as the number of productive trees (X1), urea fertilizer (X2), ZA fertilizer (X3), phonska fertilizer (X4), and labour (X5) simultaneously had significant effect on the production as the dependent variable (Y). The coefficient of determination was 0.975 indicating that the fluctuation in the clove production can be explained by its independent variables by 97.5% while the other variables not including in the model was by 2.5%.  The efficiency analysis showed that the k value of the variable of the productive tree number (X1)was < 1 suggesting that this variable is not efficient from the point of price view. By contrast the other variable such as urea fertilizer (X2), ZA fertilizer (X3), phonska fertilizer (X4) and labor (X5) had k values> 1 indicating that the use of these inputs is not efficient yet from the point of price view, as well. Keywords :Clove production, efficiency, and production input.
