Abstract

The research was conducted in Pancasari Village, District Sukasada, Buleleng regency from July to November 2013. Purpose of this study was to determine the effectiveness of combination of bio urine with biological control agent in improving productivity and control pests and diseases in greens mustard plants. This study used a randomized block design (RBD) with one bio urine treatment factors, namely bio urine added crushed with Balinese spices (base genep), crushed mimba leaves, crushed leaves of the sour sop, chopped tobacco leaves, Bacillus thuringiensis, Trichoderma viride, Beauveria sp., bio urine without a mixture of biological control agents, chemical pesticides and is equipped with controls (just doused with water).
