Abstract

Farmers too often use chemical fertilizers to help rice production, but in the long run fertilizer detrimental to land. Xanthomonas Oryzae Pv Oryzae (Xoo) is a microorganism that causes the disease of Bacterial Leaf Blight (BLB) in rice that harms farmers. Pseudomonas flourescens (Pf) is potentially the controller of Xoo and Azotobacter chrococcum (Az) causing rice to be more resistant to disease so as to help reduce the impact of BLB on rice plants in the form of organic fertilizers. The purpose of this research is to utilize corn farm waste into organic fertilizer that is resistant to BLB plant disease (bacterial leaf blight) caused by Xanthomonas Oryzae microorganism. In this research will be made of organic fertilizer from corn farm waste using rotary drum composting method with the help of Bioactivator EM4, Pf and Az bacteria. The results of this study found that the best plant growth in the variable comparison of …
