Other claims from this paper (17)
- Observation A total of 35 weed species in 18 families were recorded in jackfruit orchards.
- Observation Asteraceae and Cyperaceae followed Poaceae as weed families, with 4 species (11.4%) each.
- Observation Ludwigia octovalvis was among a consistent group of dominant weed species identified by density, cover and dominance metrics.
- Observation Ageratum conyzoides was among a consistent group of dominant weed species identified by density, cover and dominance metrics.
- Observation Axonopus compressus was among a consistent group of dominant weed species identified by density, cover and dominance metrics.
- Observation Sedges such as Fimbristylis quinquangularis also contributed significantly to the weed community.
- Observation The hygrophilous weed Peperomia pellucida showed high mean occurrence field density.
- Observation The hygrophilous weed Centella asiatica showed high mean occurrence field density.
- Observation The hygrophilous weed Pouzolzia zeylanica showed high mean occurrence field density.
- Observation Ageratum conyzoides dominated relative mean field density, indicating adaptation to high-light environments.
- Observation Ludwigia octovalvis dominated relative mean field density, indicating adaptation to high-light environments.
- Observation Diversity indices of the weed community differed modestly among agroecological regions.
- Observation Ordination analysis grouped weed species along a gradient primarily associated with density and cover.
- Observation Jaccard and Sorensen similarity indices of weed communities were uniformly high, mostly above 0.75, suggesting strong species overlap between regions.
- Observation Weed community composition varied across orchards, with some orchards showing lower species mixing than others.
- Observation Weedy rice was detected in the jackfruit orchards but was relatively infrequent.
- Recommendation The authors state the results support moving away from routine herbicide use toward ecologically based practices such as mowing before flowering and selective suppression of high-importance weeds.
