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 microorganisms Pseudomonas fluorecense: Azotobacter chroococum 1: 2 and urea. Plant growth on day 25 is higher (32.8cm) than other variables and the number of grains is 80.
Highlights
In the modern era like today the use of fertilizer has become the norm especially inorganic fertilizer to increase nutrient on soil .Many use of fertilizer very affect in agricultural progress in indonesia .Various companies fertilizer urea increase production to meet agricultural needs in indonesia .But, the use of excessive fertilizer can have a negative impact on the ground and environment
Bacterial leaf blight disease (BB) disease caused by bacteria Xanthomonas oryzae .The bacteria is can infect of paddy starting from a nursery to harvest
Agricultural waste corn put into rotary drum composter with additional aktivator em4 and bacteria Azotobacter chrocooccum and Pseudomonas flourescens composed in accordance with a variable that set before
Summary
In the modern era like today the use of fertilizer has become the norm especially inorganic fertilizer to increase nutrient on soil .Many use of fertilizer very affect in agricultural progress in indonesia .Various companies fertilizer urea increase production to meet agricultural needs in indonesia .But , the use of excessive fertilizer can have a negative impact on the ground and environment. This negative impact it should be stopped or at least reduced , because if they do not dismissed or reduced as slowly so the structure of the soil be broken . BB disease can reduce rice productivity to 60 % . [3]
