Corn is a type of plant that contains high carbohydrate. It can grow in dry season. Current climate change causes disadvantages in climatic condition such as short rainy season and long dry season. The purpose of this research is to study the effect of rhizobacteria to the yield of several corn varieties. The research was conducted in Kalasan, Sleman, Yogyakarta, Indonesia. The research used a Split Plot Design. The first factor as main factor showed a high variety of corn yield, namely Hybrid 1, Hybrid 2, Hybrid 3, and Hybrid 4. The second factor as sub-factor was rhizobacteria level (0% and 15%). The data was analyzed using Analysis of Variance. Based on the research results, there was a long dry season and short rainy season which were caused by climate change. Corn variety did not affect growth rate, yield and yield index for it’s resistant to climate change. Rhizobacteria increases the growth rate and tolerance index and making yield index to be higher than non-rhizobacteria which can help corn to survive in climate change.
