Do the previous crop and top-dressing nitrogen fertilization change the yield and physiological and sanitary quality of common bean seeds?

Abstract: The aim was to evaluate the effects of previous crop and top-dressing nitrogen fertilization on yield physiological sanitary quality common bean seeds. design used in randomized blocks a split-plot scheme, with four replications. plots were represented by three crops (sole maize, maize + Urochloa ruziziensis sole U. ruziziensis), preceding bean. subplots consisted N doses (urea) applied as (0, 40, 80, 120 160 kg N.ha-1) when had expanded leaves. Physiological seeds evaluated through germination tests, first count, emergence speed index, accelerated aging, seedling field pathogen incidence, addition crude protein content, 100-seed weight yield. study factors did not interfere Under straw, highest seed obtained dose 115 kg.ha-1, while under intercropping increase linear. Previous ruziziensis, whether cultivated or intercropped promotes greater seeds, does quality, content
