Usage management of inorganic fertilizers into organic fertilizers can reduce the attack level of brown planthopper. The organic matter can increase tolerance of plants to pest attacks. The objective of this research was to determine the cow manure dosage against the attack level of brown planthopper on several paddy plants varieties. This research was conducted on paddy fields in Serdang Village, Beringin Sub-District, Deli Serdang District from March to July 2018. This study used a two-factor randomized block design (RBD) with three replications. The First Factor was the dosage of fertilizer which consisted of 4 treatments (inorganic fertilizer, 50 kg/plot of manure, 100 kg/plot of manure and 150 kg/plot of manure). The second Factor was the varieties which consisted of 2 varieties treatment (Ciherang and Inpari 10). Result showed that P 2  fertilizer dosage (100 kg/plot) was able to reduce the percentage of brown planthopper attack. V 2  variety (Inpari 10) was a treatment that can reduce the percentage of brown planthopper attack. The interaction between fertilizer dosage and variety of V 2 P 2  (Inpari 10 + 100 kg/plot) was the best treatment in suppressing the percentage of brown planthopper attack.
