| Abstract: | Two experiments, comparing the effects of direct-drilling openers and residue on barley seedling establishment in a saturated soil were conducted. One was in the absence of earthworms and the other in the presence of earthworms. In the absence of earthworms overall seed/seedling performance was poorer than that in the presence of earthworms. The absence of earthworms caused lower oxygen diffusion rates, higher soil bulk density and soil moisture content compared to the presence of earthworms and negated any effect of opener type or crop residue. By contrast, in the presence of earthworms opener type and crop residue conditions had significant effects on seed/seedling performance, with hoe and winged openers in residue recording the highest counts, and a triple disc opener in residue and winged opener without residue recording the lowest counts. |
