Abstract

A biotest with Brassia juncea L .vegetable as a test plant was used to evaluate chicken manure composted with native microorganism (NM), Bio-plant product and fresh water.

Brassica juncea L

The mixture of native microorganisms (NM) was easy to make, was stable and low cost in comparison with the commercial Bio-plant product. The populations of micro-organisms were much higher in compost inoculated with both " NM"  and " Bio-plant" compared with the control (Figures 1-3).  The yield of Brassica juncea increased curvilinearly with level of application of the " NM"  compost with the peak occurring at 30 tonnes/ha of compost (Figure 4).
