ABSTRACT
The study was conducted in Keputran village, Tanggamus District, Lampung Province. The aim of this study was to examine a proper combination of NPK fertilizer and chicken manure for the vegetable crops, especially chinese mustard (Brassica campetris Var. Chinensis L.) in order to increase the production. A randomized completely block design was used in this experiment with ten treatments and three replications. The results showed that the application of chicken manure with the dosage of less than 5 Mg ha-1 combined with NPK fertilizer did not effective to affect the increasing of growth and production of chinese mustard. Meanwhile, application of chicken manure more than 5 Mg ha-1 combined with NPK fertilizer was significantly affected the growth, production of chinese mustard and soil properties i.e. total-C, total-N, available P , exchangeable K, and humic and fulvic acid. The application of chicken manure effective to reduce NPK fertilizer. The best yield was found in using 50% of NPK fertilizer and 50% of chicken manure (10 Mg ha-1).
