Other claims from this paper (12)
- Association Increasing nematode population density reduced spring barley yield.
- Association Grain yield of spring barley was reduced by 3.5% for every 10 juveniles/g soil of nematode.
- Observation Fertile ear production was the major but not sole yield component of spring barley affected by the nematode.
- Observation The field trial indicated an equilibrium nematode density of about 40 juveniles/g soil in spring barley.
- Observation Yield loss in barley could be expected at small preplant nematode densities.
- Observation Economically significant barley yield loss occurred at initial nematode densities greater than 20 juveniles/g soil.
- Intervention effect Aldicarb at 5.6 kg a.i./ha prevented yield loss in pots at 98 juveniles/g soil of nematode.
- Intervention effect Aldicarb did not increase yield of spring barley in uninoculated pots.
- Intervention effect Aldicarb applied to field plots had neither a yield nor a final population density effect on spring barley and nematode.
- Association Changed cropping patterns in Wales were associated with increased field populations of the nematode in spring barley systems.
- Observation A glasshouse experiment confirmed the field trial results for spring barley.
- Association Significant linear regressions relate nematode population density to barley growth and yield.
