✓ located verbatim in the source · abstract, characters 3515–3827 Other claims from this paper (19) Intervention effect Full-season sicklepod competition made soybean plants less branched, with fewer leaves and thinner stems than the control. Intervention effect The presence of sicklepod did not affect soybean plant height. Intervention effect Under weed competition, soybean node number decreased in one of the two experiments. Intervention effect Under weed competition, number of pods, number of seeds and seed yield per plant were all similarly reduced. Intervention effect Under weed competition, seeds per pod decreased to a lesser extent than the other yield components. Intervention effect Increasing sicklepod infestation significantly diminished soybean seed yield per unit area. Intervention effect At 25,000 sicklepod plants/ha, soybean seed yield was reduced by 47% relative to the control. Intervention effect At 53,000 sicklepod plants/ha, soybean seed yield was reduced by 65% relative to the control. Intervention effect At 77,000 sicklepod plants/ha, soybean seed yield was reduced by 73% relative to the control. Intervention effect As soybean row distance decreased, branch number, leaf number and stem diameter decreased. Intervention effect As row width narrowed, soybean plant height increased. Intervention effect As row spacing was reduced, number of pods, number of seeds and seed yield per plant diminished. Association The maximum difference between row distances for these yield attributes was found in soybean under weed-free conditions. Intervention effect As row width decreased, soybean seed yield per unit area increased. Intervention effect Soybean in 90-cm rows yielded less than soybean in 60- and 30-60-cm rows in the variable pattern. Intervention effect Soil phosphorus, potassium, calcium and magnesium contents were not affected by sicklepod levels or soybean populations. Intervention effect Neither sicklepod densities nor soybean row distances influenced seed germination and seedling vigor in the next soybean generation. Observation Sicklepod was a strong competitor with soybean at all density ranges investigated. Intervention effect Varying row spacing alone gives only limited success in managing sicklepod in soybean. Observation observed original result measured Claim · model-written summary
