Inorganic fertilizers is associated with reduction in some soil properties and crop yields over time. Application of organic fertilizer has positive effects in maintaining the soil properties. The aim of this research was to study the growth and physiology of peanuts on different doses of cow manure and NPK 16 fertilizers. The study was carried out in research field of the Laboratory of Ecology and Plant Production, Agriculture Department, Faculty of Animal and Agricultural Sciences Diponegoro University, Semarang. The design used was split plot. As the main plot was doses of cow manure (0, 5 and 10 tons / ha), subplots was NPK 16 fertilizer (0, 25, 50, 75, and 100 kg N / ha), with three times replications. Parameters observed were plant height, number of leaves, activity of nitrate reductase (ANR) and chlorophyll contents. There was interaction between manure and NPK 16 doses to total chlorophyll content of leaves. Separately, cow manure and NPK 16 significantly affected the plant height, ANR and total chlorophyll but not significantly effect on number of leaves. Cow manure and NPK 16 affected on increasing of plant height, ANR and total chlorophyll contents of peanuts.
