Abstract

Agricultural intensification program in Indonesia which is carried out by using high yield variety, high chemicals use and soil disturbances tends to trigger land exploitation. Land exploitation, performed without considering the lands capability can generate degradations on the land itself. Various methods have been used to determine land exploitation level, including evaluation of soil microbe resources as on soil component. This research is aimed to assess land exploitation level, based on the amount of microbial population. The result of this research is expected to add the soil quality standard criteria. In the case study performed in Dieng plateau, representative soil sampling method was used. The amount of microbial population can be enumerated using plating and MPN method. Based on nutrient availability to indicate the soil biological characteristics, the soil under the trees, shrub, and Colocasia were classified as “below normal”, and the soil under the grass, tobacco, cabbage and potato were classified as normal. It shows that the land exploitation at the agricultural soils were still in the range of its land capability.

Abstract

Pseudomonas fluorescensandP. putida are Plant Growth Promoting Rhizobacteria (PGPR) that can produce growth hormone. The objective of this study is to know the effects of those two combined species of PGPR on seedling root growth of Jatrophacurcas. The condition of the seedling root determines the success of dry land cultivation. The root which has wider coverage, is larger in number, and is bigger in diameter makes seedling more resistant to stress in dry land environment. In the experiment, two kinds of plant materials are used for seedling, the Jatropha seed and stem material, which are treated in a mixed culture of PGPR. For the Jatropha seed, this mixed culture of PGPR is given at the same time of cultivating the sprout on the seedling medium. For the stem cutting, the PGPR is poured in together during the first watering of the seedling cultivation medium. In the fourthweek, the observed growth parameters are root length, root diameter, primary and secondary lateral root numbers, Root Length Density (RLD), Frequency of Lateral Root (FLR), and Specific Root Length (SRL). These data are analyzed using analysis of variant with DMRT test at 0.05 level of significance. The result of this study shows that PGPR tend to reduce FLR values on the seedling root made from seeds. On the seedling root made from stem cutting, PGPR increase the root length, primary and secondary lateral root numbers, root diameter, FLR and SRL values as well. Keywords: Pseudomonas, PGPR, root, Jatropha
