Weed Tolerance and Suppressive Ability of Potato Cultivars to Natural Weed Infestations

Ahmad Omid Siddiqui; Khawar Jabran Journal of Crop Health 2025. doi:10.1007/s10343-025-01117-9

Other claims from this paper (10)

Intervention effect Weeds reduced potato plant height by 10–37%.
Intervention effect Weeds reduced potato fresh weight by 21–44%.
Intervention effect Weeds reduced potato yield by 15–48%.
Observation Weed dry weight ranged from 146.7 g m −2 for Lady Olympia to 428.3 g m −2 for Arizona.
Observation Under weeds, Electra tuber yield was 13.84 t ha −1.
Observation Under weeds, Agria tuber yield was 25.15 t ha −1.
Association Early emergence, rapid canopy development and greater biomass characterized weed-suppressive cultivars.
Association Taller cultivars with higher yields were more weed tolerant.
Observation Lady Olympia suppressed weed dry weight by at least 60%, the highest suppression.
Observation Agria had superior weed tolerance with minimal yield loss.

AN ANALYSIS OF THE EFFECTS OF INFECTION WITH LEAF‐ROLL VIRUS ON THE GROWTH AND YIELD OF POTATO PLANTS, AND OF ITS INTERACTIONS WITH NUTRIENT SUPPLY AND SHADING

D. J. WATSON; J. H. WILSON Annals of Applied Biology 1956. doi:10.1111/j.1744-7348.1956.tb02134.x

Other claims from this paper (19)

Intervention effect Infection increased leaf and stem dry weight.
Intervention effect Infection slightly decreased root and stolon dry weight.
Intervention effect Nitrogenous fertilizer reduced virus-related tuber dry weight loss.
Intervention effect Phosphorus and potassium did not affect virus-related tuber loss.
Intervention effect Infection decreased net assimilation rate through early July.
Observation Infected plants had higher later net assimilation rate.
Intervention effect Infection decreased leaf area until early July.
Intervention effect Infection delayed leaf senescence and increased late leaf area.
Observation Mean infection-related net assimilation rate decrease was about 20%.
Observation Mean infection-related leaf area decrease was 4%.
Mechanism Older rolled leaves had diminished photosynthetic efficiency underlying lower net assimilation.
Observation Nutrient effects on net assimilation and interactions with infection were small and rarely significant.
Intervention effect Nitrogenous fertilizer increased leaf area throughout growth.
Intervention effect Phosphorus increased early leaf area.
Intervention effect Phosphorus hastened senescence and decreased August leaf area.
Intervention effect Potassium increased leaf area particularly later in growth.
Observation Infected plants had more leaves than healthy plants beyond early growth.
Intervention effect Shading decreased net assimilation rate and increased leaf area without affecting yield.
Observation Virus-related yield loss was smaller in Up-to-Date than Craig’s Defiance.
