The progress in agriculture technology have been able to develop worthwhile soil microbial to increase crop productivity and peaceful to environment. The purpose of this research is to study the effect of the use of bio fertilizers Illetrinut on peanuts variety Jerapah, and its interaction with the addition of manure to reduce the use of chemical fertilizers. Design of experiments carried out was factorial randomized block design, with the factor I was organic fertilizer comprised of (1) without any animal manure, and (2) given manure, and the factor II was awarding Illetrinut inoculant of, comprised of (1) without inoculant, given inorganic fertilizer P, K, (2) without inoculant, given inorganic fertilizer N, P and K, (3) inoculation Illetrinut A, and (4) inoculation Illetrinut B. The result shows that bio fertilizer Illetrinut may use on peanuts, which can provide quite good result be coupled with manure application by dosage 1.6 t/ha. On the application of bio fertilizer Illtrinut for the crops of peanut variety Jerapah are able to form pretty much root nodules (>100 nodules/plant), and produce the yield average 10.50-15.84 pods/plant and 41.00-64.33 seeds/plant.
