| Abstract/Contents: | "The effect of management practices on yield of cabbage (Brassica oleracea) in monocultures and living mulch systems using perennial ryegrass (Lolium perenne) was compared in a 1986 field study in Corvallis, Oregon. Cabbage yield was used as an indicator of the relative competitive ability of the five interrow treatments. Five water levels (20, 35, 63, 83 and 100%), imposed by a line source, were factorially combined with five interrow treatments. Cabbage at 41,667 plants/ha had half of the plot area in grass managed by mechanical (2 mowings), chemical (one application at .17 kg ai/ha of fluazifop-p-butyl {(±)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy] -phenoxy]propanoate} or no suppression. Cabbage monocultures had bare ground between rows or another row cabbage, doubling the density. Interrow cabbage decreased the yield of the remaining cabbages, doubling the density. Interrow cabbage decreased the yield of the remaining cabbages as much as the mechanically and unsuppressed grass - by 14% at the 100% water level, though total marketable yield for the double density plots was 64% higher than for the low density monoculture. Compared with the low density monoculture, chemically suppressed grass decreased the yield as much as the other treatments at the 65% water level, less so at the 83% water level and was no different at the 100% water level. Results suggest that cabbage and grass are equally competitive against cabbage. If enough water is available, a living mulch system may yield as well as monoculture. |
