Effect of Biochar Application on the Growth of Cassava and Maize, Maize Yield and Soil Erosion in Cassava+Maize Intercropping System

Abstract:
Background and Objective: In the tropical soil, soil organic matter is important not only to provide nutrients and improve soil fertility, but also enhance soil physical properties to reduce soil erosion. Biochar as a recalcitrant organic matter provides opportunity to improve soil physical, chemical and biology properties for a longer period compare to other organic matter. A field experiment was carried out to investigate the effect of biochar application in soil erosion, cassava growth and maize yield in cassava+maize intercropping system. Materials and Methods: The tested treatments consisted of two factors, i.e.,: biochar applications (no biochar, with biochar) and cropping system (cassava monoculture, maize monoculture and cassava+maize intercropping). There were two replications of each treatment. Results: The experimental result showed that the biochar application improved cassava growth both in the monoculture and the intercropping system. Maize yield was found to be increased with biochar application in both cropping systems, however there was no significant difference between cropping systems. The highest maize yield in this experiment (4.626 t ha1) was obtained by maize monoculture applied with biochar. The higher plant growth under biochar resulted in better land cover, thus reduce the surface runoff and subsequently soil erosion. Conclusion: Biochar used in this study showed improvements not only to increase maize yield, but also improve soil physical properties such as soil aggregate stability. Hence, due to better land cover and higher soil aggregate stability, the loss of soil from erosion was lower in biochar treatment compare to the no biochar treatment.
