Fig 6. Average surface area (cm²), volume of root (%), number of laterals and lateral angle (°) of tillage radish root systems.

(A) Average surface area of tillage radish root (cm²). (B) Average volume of tillage radish root as a percentage of the soil volumes. Due to extreme range of data values data was not subject to ANOVA. (C) Average number of lateral roots observed protruding from the taproot. (D) Average angle of lateral roots protruding from taproot. For all graphs data is presented for both the compacted and uncompacted zones over two time periods. Bars denote means, whiskers pooled (A, C, D) or individual (B) s.e.
