Nitrogen Rate, Vine Density, and Weed Management Affect Colonization of Cranberry Beds following Disturbance

摘要: Abstract The interactive effects of nitrogen rate (0, 28, 56, and 112 kg/ha), vine density 1.8, 3.6, 5.4 t/ha the cultivar ‘Stevens’), weed management (preemergence herbicide, postemergence control, inoculation with seeds, untreated) were determined on recolonization open spaces caused by localized biomass removal in a newly planted commercial cranberry bed. To assess effect 64 treatment combinations initial colonization, all was removed from randomly selected 930-cm2 area each plot Year 1. quantify disturbed area, same quadrat resampled plant collected 2. Cranberry production increased quadratic fashion increasing N rates for densities except zero. year after disturbance positively correlated present previous year. Weed stem disturban...
