Abstract :
Background and objective: Baggass of sugarcane and wheat straw are the most available material for composting in Khuzestan province. Baggass has the self-inflammable property. This baggass property is a source of environmental pollution. It is important that a method is introduced to proper baggass compost as fast as possible in order to make it to a usefull and safe production. Therefore, this study was conducted to compare the quality of compost from two types of plant residues bagasse and wheat and their consumption and also to minimize the time period of compost preparation using different methods. Material and Methodology: for this purpose, a trail was carried out in a factorial CRB design at three replications during two years in Shavoor (Khuzestan) Agricultural Research Station. In this experiment, preparing duration and compost quality were investigated in two kinds (wheat straw and baggass of sugarcane) and two amounts (20 and 40%) of raw materials and the three preparing methods (Traditional, Rapid, and Bio-enriched). Findings: Results showed that the bio-enriched method was the fastest method to propering in comparison with the others (2 months vs. 4 months). And the best composition also is 40% baggass, 50% filtercack of sugarcane and 10% cow manure. Discussion and Conclusion: Therefore, it is recommended to use wheat straw or sugarcane bagasse to prepare compost and the enriched method, ie using Trichoderma and Azotobacter bacteria. It is better to use a combination of 40% straw or bagasse, 40% sugarcane filter cake, less than 20% cow manure and the rest of sheep manure or poultry manure. Conversion of sugarcane bagasse prevents the self-igniting dangers of this substance in the depot and as a result of the resulting environmental pollution.
