Abstract: Background and Objectives: Vegetable soybean has been developed rapidly due to its capability to fulfilling not only nutritious food but also fodder forage. The research aims to observe the responses of vegetable soybean as a functional food and forage feed in volcanic soil which were planted and fertilized by using cow manure and chemical fertilizers. Materials and Methods: The research was arranged in a factorial randomized complete block design with 3 replications. The first factor was 3 various rates of cow manure fertilizer (10, 20 and 30 t ha–1). The second factor was source and dosages of nitrogen: consists of urea dosages (50, 75 and 100 kg ha–1) and Ammonium Sulphate (AS) dosages (100, 150 and 200 kg ha–1). Plant responses that had been observed were: growth components, pod yields and yield of forage feed. Results: It obtained that there was no interaction between cow manure rates with nitrogen fertilizer sources on all observational variables. The rate 10-30 t ha–1 of cow manure does not affect the growth, pod yields and forage feed. Conclusion: The application of cow manure 10 t ha–1 rate and nitrogen ammonium sulphate source dosage of 200 kg ha–1 increases plant growth, yield of pods functional food and vegetable soybean forage feed.
