Other claims from this paper (16)
- Intervention effect Weed competition reduced canopy volume by 16% to 38% in highbush blueberry.
- Intervention effect Weed competition reduced leaf nitrogen concentration in highbush blueberry.
- Intervention effect Weed competition reduced berry yields by up to 92% in highbush blueberry.
- Intervention effect Weed competition reduced berry number by up to 91% in highbush blueberry.
- Intervention effect Weed competition reduced berry specific weight by up to 21% in highbush blueberry.
- Intervention effect Pine needle mulch (PN) reduced aboveground weed biomass by 55% compared with the control in 2005.
- Intervention effect Pine needle mulch (PN) reduced aboveground weed biomass by 73% compared with the control in 2006.
- Intervention effect Mulch treatment substantially altered the distribution of weed species.
- Intervention effect Both composts prevented some weed emergence, including sheep sorrel.
- Mechanism Weed seeds germinating in composts, especially SC, likely grew prolifically because of available nutrients in the composts.
- Observation No detrimental effect on short-term plant productivity of highbush blueberry was noted under mulches with high C:N ratios.
- Intervention effect Composts increased leaf tissue elemental (NPK) composition in highbush blueberry.
- Intervention effect Fruit soluble solid (sugar) content was significantly lower under pine needle and manure-sawdust compost mulches than under seafood waste compost.
- Intervention effect Total phenolic content of highbush blueberry was unaffected by mulches.
- Recommendation Mulch application is recommended to improve organic highbush blueberry productivity through soil properties, nutrient availability and weed suppression.
- Recommendation Precautions are recommended to avoid excess nutrient loading and weed seed contamination of mulches.
