Claim · model-written summary

The authors explain the yield increase through fewer and lighter O. foetida attachments and a slight reduction in Najeh shoot dry weight.

Taxon: faba beanVicia fabae2
Interactor: O. foetidaOrobanche foetidae0parasite
Outcome: Seed yielde1
Qualifier: reduced number and dry weight of O. foetida attachments and a slight decrease in shoot dry weighte0

Verbatim

e0
“This can be explained by the reduced number and dry weight of O. foetida attachments and a slight decrease in shoot dry weight of the resistant cultivar.”

Title

Effect of sowing date onOrobanche foetidainfection and seed yield of resistant and susceptible faba bean cultivars

Z. Abbes; F. Sellami; M. Amri; et al. Acta Phytopathologica et Entomologica Hungarica 2010. doi:10.1556/aphyt.45.2010.2.3

Other claims from this paper (8)

Intervention effect Late sowing significantly reduced emerged O. foetida shoot number in resistant Najeh.
Intervention effect Late sowing significantly reduced emerged O. foetida shoot dry weight in Najeh.
Intervention effect Late sowing did not significantly reduce emerged O. foetida shoots in Badi.
Intervention effect December sowing reduced underground tubercle number in both cultivars.
Observation With December sowing, attachments emerged on Badi but not Najeh, indicating delayed parasite growth on Najeh.
Intervention effect Late sowing significantly increased faba bean seed yield.
Observation Najeh produced much higher seed yield than Badi.
Recommendation The authors recommend combining resistance and late sowing to control O. foetida in Tunisia.

Title

Mycorrhizal colonization and nutrient uptake of dry bean in manure and compost manure treated subsoil and untreated topsoil and subsoil

David D. Tarkalson; Von D. Jolley; Charles W. Robbins; et al. Journal of Plant Nutrition 1998. doi:10.1080/01904169809365529

Other claims from this paper (10)

Association Soil organic matter and leaf zinc concentration correlated with improved bean yield.
Intervention effect Manure had no significant effect on mycorrhizal spore numbers.
Observation Root colonization increased from under 5% at day 21 to 58% at day 56.
Intervention effect Manure or composted manure increased root colonization relative to untreated subsoil; topsoil had the highest colonization.
Intervention effect Topsoil promoted the greatest early colonization and zinc uptake.
Intervention effect At day 56, manured subsoil gave zinc absorption equal to topsoil and above the subsoil control.
Observation Compost manured subsoil did not show the increased zinc uptake.
Intervention effect Composted manure decreased bean root and shoot weight.
Association Uptake of other nutrients was unrelated or negatively related to mycorrhizal infection.
Mechanism Manure-stimulated mycorrhizal colonization could explain higher bean yield and zinc in manured subsoil.

Title

Dryness, wetness and temporary flooding reduce floral resources of plant communities with adverse consequences for pollinator attraction

Julia Walter Journal of Ecology 2020. doi:10.1111/1365-2745.13364

Other claims from this paper (8)

Intervention effect Wetness and especially dryness decreased the species richness and biomass proportion of insect-pollinated herbaceous species.
Intervention effect Flowering herbaceous plant individuals occurred less frequently under wetness and especially dryness.
Intervention effect Permanent wetness decreased the floral sugar content of Trifolium pratense.
Intervention effect Wet, temporarily flooded and especially dry communities were visited by pollinators less often.
Intervention effect Active pollinators spent less time within wet and flooded communities.
Intervention effect Active pollinators did not visit dry communities at all.
Intervention effect Seed and flower weight of T. pratense decreased in flooded and dry communities.
Mechanism Negative effects of wetness and temporary flooding on floral resources were mostly caused by a decrease of insect-pollinated herbaceous species.
