Abstract

Abstract Land is one of the determining factors for the success of plant cultivation, because the availability of nutrients is determined by the level of land resources. Agricultural land in general can be in the form of wet and dry land. Wetlands have been optimally potential, generally used for growing food crops, vegetables and secondary crops. Dry land is a stretch of land that is not saturated with water throughout the year, or has never been flooded for a certain period of time. The condition of agricultural land, especially dry land, is strongly influenced by climate change. Climate change such as El Nino has caused a long dry season with below normal rainfall intensity. Long-term El Nino events result in a lack of water availability in the soil, causing the land to dry out. This phenomenon has had a negative impact on agricultural land and crops. One of the plants that can be cultivated on dry land is citronella which is given the arbuscula mycorrhizal fungus. Utilization of arbuscular mycorrhizal fungi is intended to help the function of roots to absorb water and take up nutrients, which is a limiting factor for citronella in dry land. The method used in this research is a literature study by collecting data to see various study results that are relevant to the problem being studied. References used as data sources are books, scientific journals, scientific magazines, newspapers, research reports and interviews with various resource persons. The purpose of this study was to determine the potential of dry land to be used as land for the cultivation of citronella plants and the use of arbuscular mycorrhizal fungi to increase the growth and yield of citronella plants in dry land. The results of the research are dry land has great potential to be used as land for cultivation of citronella plants and the use of arbuscular mycorrhizal fungi can increase the growth and yield of citronella plants in dry land. Keywords : Optimization, dry land, citronella, inoculated, arbuscular mycorrhizal fungi
