Tóm tắt

The effect of soil compaction on photosynthesis, plant growth and root rot severity of white bean was investigated in a controlled environment using healthy and root rot diseased soil. There was a highly significant reduction in root biomass, shoot growth and total leaf area of plants grown in compacted soil. Soil compaction also significantly reduced photosynthetic rate and increased root rot severity. The reduction in growth for plants subjected to soil compaction is attributable partly due to a decrease in photosynthetic rate and to an increase in root rot severity. Key words: Phaseolus vulgaris L., Fusarium root rot, bean (white)
