| Abstract | ||||
| A pot experiment was conducted using a calcareous soil in pots (6 kg capacity) receiving either half, same or double the recommended dose (10 ton /fed) of either aerobic or anaerobic compost. The compost was subjected to one of three composting periods; 3, 6 or 9 months. Wheat was planted up to maturity followed by sudangrass which was cut three times to study the concurrent and residual effects of compost. Re-sults obtained could be summarized in the following: Dry matter yield of wheat and sudangrass were affected by period of composting and ap-plication rate treatments revealing the significant superiority of 6 month composting period under aerobic conditions and 4% dose of application. • Uptake of nitrogen, phosphorus and potassium by plant was improved by increasing the dose of application for the 6 month aerobic compost-ing and 4% dose of compost. However, for practical recommendation, the studied factors should be tested in field. | ||||
