Abstract


This research aimed to evaluate the effect of the domestic waste of compost growing media and the
residual of waste pit and the combination of both on the contents of N, P, K also the production of
mustard (Brassica oleraceae L.) on inceptisol soil. This research was conducted in the compost
yard in Kecamatan Sunggal Kabupaten Deli Serdang and analysis continued in the riset and
technology laboratory of agricultural faculty of university of North Sumatera. This study used
Randomized Blok Design (RBD) which is consisted of 9 treatments and 3 replications. The
treatments are M1 (100% soil), M2 (75% soil + 25% compost), M3 (50% soil + 50% compost), M4
(25% soil + 75% compost), M5 (75% soil + 25% residues of the waste pit), M6 (50% soil + 50%
residues of the waste pit), M7 (25% soil + 75% residues of the waste pit), M8 (50% compost+ 50%
residues of the waste pit), M9 (100% residues of the waste pit). Where the result is that the
provision of domestic waste compost and residues of the waste pit and the combination of both,
very significantly increased value the pH of the soil, C-organic, N-total, P-available, K-exchange as
well as the production of the wet weight mustard plant on inceptisol soil.
