Taxon: potato ✕

A claim can belong to several research areas, so group counts add up to more than the total.

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Organism groups follow NCBI Taxonomy: the spellings of one organism are merged, a claim naming several organisms sits in each group, and claims whose value names no organism are under “not stated”.

Biochar-Poultry Manure Compost Alters Temperature and Nitrogen Dynamics during Composting and Improves Potato Growth Following Field Application

Other claims from this paper (12)

Intervention effect Compost with 40% biochar addition reduced N loss from the compost mass compared to the control, to 29.9%.
Intervention effect Compost with 20% biochar addition reduced N loss from the compost mass compared to the control, to 32.3%.
Intervention effect Biochar addition caused a more rapid temperature increase during composting.
Intervention effect Biochar addition truncated the thermophilic phase of composting.
Intervention effect Finished compost with 40% biochar had greater NO3--N concentration.
Intervention effect Finished compost with 40% biochar had lower electrical conductivity.
Intervention effect Finished compost with 40% biochar had greater carbon to nitrogen ratio.
Intervention effect Finished compost with 40% biochar had greater total carbon content.
Intervention effect Application of composted biochar at 40% increased potato tuber weight by 40% relative to an unamended control.
Intervention effect High application rates of compost tended to increase total N in soil relative to an unamended control.
Intervention effect No differences in soil properties were detected between compost and composted biochar treatments.
Intervention effect Assuming no N was lost from the added biochar, the difference in N loss was not significant at P = 0.100.

Title

Seasonal Variation in Pathogenicity of Phytophthora infestans

Other claims from this paper (10)

Association Potato leaflet lesion area varied periodically during the year after inoculation.
Association Symptoms ranged from pinpoint necroses to sporulating lesions by season and cultivar.
Association Lesion size differed significantly among seasons.
Association Lesion area was largest in late spring or autumn.
Association The autumn lesion-area increase was usually significantly lower than the spring increase.
Observation In-vitro P. infestans sporulation density showed periodicity.
Association Sporulation and lesion-area peaks occurred in different seasons.
Association Highest disease level coincided with lower in-vitro sporulation density.
Association Lesion-area variation seemed unrelated to variation in plant reaction.
Mechanism The authors hypothesized that fungal pathogenicity variation caused lesion-area changes.
