Abstract

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 Indonesia. 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, namely 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. Parameters were observed, then analyzed for variance and continued with Duncan's multiple range test based on Steel and Torrie (1990). There was interaction between manure dosage and NPK 16 to total chlorophyll content of leaves. Dose of cow manure and NPK 16 each significantly affected for plant height, ANR and total chlorophyll but no significantly effect on number of leaves. Cow manure and NPK 16 affected on increasing of plant height, ANR and total chlorophyll contents of peanuts. Keywords: organic fertilizer, cow manure, inorganic fertilizer, NPK 16, peanut plant
