Other claims from this paper (11)

Intervention effect White mulch increased rice grain yield about 10-15% in standard and late cultivation.
Intervention effect White mulch did not increase grain yield in early cultivation.
Intervention effect White mulch lowered daily maximum soil temperature.
Intervention effect White mulch increased reflection of radiation at the soil surface.
Intervention effect White mulch maintained higher root respiratory activity at later growth stages.
Intervention effect White mulch did not enhance leaf photosynthetic activity.
Intervention effect After heading, treated rice plots had more assimilated products than untreated plots.
Mechanism The authors attributed increased assimilated products to greater radiation reflection from the soil.
Intervention effect White mulch before panicle formation was unfavorable for growth.
Intervention effect White mulch before panicle formation was unfavorable for grain yield.

Other claims from this paper (17)

Observation Flower thrips feeding injures flower filaments and causes premature pollen loss and reduced pollination and seed set.
Observation About 10 thrips per flower or floret were needed for meaningful injury.
Observation An estimated 9,000 to 10,000 thrips per seed head would be needed for economic injury and seed loss.
Observation Observed infestations reached 1900, 2400 and 3600 thrips per head.
Observation These thrips densities did not reduce onion seed set, yield, size or viability.
Intervention effect Thrips increased pollination and seed set over controls in every experiment.
Intervention effect Adding pollinators increased seed production and viability relative to thrips alone.
Observation Fly pollinators and two heads per replicate cage were needed for adequate seed set.
Observation Across three years, thrips density never caused economic onion seed loss.
Intervention effect Two or three parathion applications satisfactorily controlled thrips.
Intervention effect Two or three diazinon applications satisfactorily controlled thrips.
Intervention effect Those insecticide treatments did not alter seed set or yield.
Intervention effect Parathion during bloom reduced bee and fly pollinators for about three days.
Intervention effect One prebloom dimethoate application gave outstanding thrips control.
Intervention effect The single prebloom dimethoate application did not reduce pollinators.
Intervention effect An additional bloom dimethoate application reduced pollinators for up to ten days.
