Abstract:

Coffee peel can be used as a potential organic fertilizer source for agricultural production, but the application of the coffee peel not rotten can inhibit the growth of coffee seedlings. Coffee peel and shattered coffee peel rotten with nothing or cellulase and pectinase were carried out to investigate the effects of different treatments on the coffee peel nutrient content and plant growth, and to provide basis for coffee peel fertilizer utilization. The results of laboratory tests showed that there was no significant difference on the nutrient content of coffee peel among the treatments, whereas the organic matter in the shattered coffee peel treated with cellulase and pectinase decreased by 7.90% compared with the coffee peel treated with no enzymes. Greenhouse pot experiments showed that the application of well-rotten coffee peel could significantly promote the growth of coffee seedlings, increase the leaf photosynthetic rate, chlorophyll content and nitrogen balance index. The application of shattered coffee peel treated with cellulase and pectinase increased the biomass production of coffee plant, leaf photosynthetic rate, chlorophyll content and nitrogen balance index over 50% compared with the control. Conclusively, shattered coffee peel treated with cellulase and pectinase was suggested to be used to promote the growth of coffee plants.

Key words: coffee peel, cellulase, pectinase, compost, growth of coffee plant
