Abstract :

This study was carried out at the Demonstration Farm, Agricultural Research Corporation, Shambat, Khartoum North, Sudan in 2014/2015 and 2015 /2016 seasons. The objective was to come up with a compost preparation procedure to improve the quality of the compost and hence crop productivity. Farm yard (FYM) and Chicken manures (CHM) were collected from the Top Farm and the Faculty of Animal Production, University of Khartoum, respectively and were mixed at a ratio of 10:1 (FYM:CHM) and moistened to 50% of its volume. The mixed material was divided and composted into four preparations; aerobic, forced aeration at the rate of 10 CFM, anaerobic (buried in 90cm auger holes) and vermin (1kg vermin/2kg organic matter). The experiment was laid out in a completely randomized design (CRD). The composts prepared were sampled every month and analyzed for organic carbon (OC); nitrogen (N); phosphorus (P) and potassium (K). Microbiological examinations were made every month. Compost maturation was reached by reduced volume, brown color and crumbly with earthy smell. It was observed that the best and appropriate time of opening compost was after three months. The results obtained showed that the best treatment was the aerobic, followed by forced aeration in the two seasons. The results illustrated that the bacteria population was significantly (P<0.05) different from the aerobic and the vermin treatments. The nitrogen, phosphorus and potassium were significantly (P<0.05) different in the two seasons in the aerobic treatment compared with other treatments, whilst potassium and phosphorus were significantly (P<0.05) lower for the anaerobic treatment in the first season.
