Title
Effect of tillage systems, mulches and nitrogen fertilization on spring barley (Hordeum vulgare)
I. Małecka; A. Blecharczyk Agronomy Research 2008
Other claims from this paper (13)
- Intervention effect Cover crops raised spring barley grain yield by 10-31% compared with no mulch.
- Intervention effect Straw mulch reduced barley grain yield compared with no mulch.
- Intervention effect Reduced tillage reduced spring barley grain yield by 7% against conventional tillage.
- Intervention effect No-tillage reduced spring barley grain yield by 12% against conventional tillage.
- Intervention effect Sowing spring barley after oat-pea mixture decreased the adverse yield response under reduced and no tillage.
- Observation Without nitrogen fertilizer, legume cover crops gave similar grain yield to 50 kg N ha -1 after white mustard or phacelia and 100 kg N ha -1 without mulch.
- Observation No tillage-by-nitrogen interaction was evident for grain yield, dry matter production and plant-N uptake.
- Intervention effect Cover crops decreased total weed populations relative to no mulch.
- Observation Total weed density under no-tillage was 108 plants per m 2.
- Observation Total weed density under reduced tillage was 322 plants per m 2.
- Observation Total weed density under conventional tillage was 416 plants per m 2.
- Intervention effect Stem base and root disease infestation was higher under reduced and no tillage than conventional tillage.
- Intervention effect Stem base and root disease infestation was higher after straw mulch and no mulch than cover crops.
