【 摘 要 】

Dryland lacks water, unfulfilled nutrient supply, lack of abiotic and biotic elements, and very little rainfall. The area of dry 6 6land in Indonesia reaches 144.47 × 10 ha. About 99.65 × 10 ha are dry land with potential for agriculture, and around 44.82 6× 10 ha are dry land with no possibility for agriculture. Many arid lands in Indonesia cause significant problems, especially in the agricultural sector. The problem often occurs due to the constraints of plant growth factors, including planting media, water, light, wind, and nutrients. This study aims to determine the resistance of bacteria to drought stress and high salinity as well as their ability to produce IAA (Indole Acetic Acid). The method used is in vitro. The results obtained are various kinds of bacteria, the nature of bacteria in binding gram, and osmoprotectant bacteria. Bacteria tested from the dry land of annual plants could effectively survive on PEG 6000 media NaCl even at high concentrations. The best bacteria that can survive in the saline conditions were B7, B8, B9, B10, while the potential as plant growth hormone bacteria are B6, B7, B8, B9, B10.
