Managing water use and growth of a perennial ryegrass living mulch in Christmas trees

Creator:: Murray, Helene
Abstract:: A living mulch system consists of growing a regulated cover crop with an economic crop. Living mulches are often interplanted with horticultural crops, but competition for water can adversely affect crop production. Various management practices may limit the negative effects. Studies were conducted for two purposes: (1) to determine if...

Interaction of crop plant population with weed competition in corn (Zea mays L.), bush snap beans (Phaseolus vulgaris L.), and onion (Allium cepa L.) at differing stages of development

Creator:: Williams, Clarence Frank
Abstract:: Yield reductions due to competition of weeds with crop plants can be extremely important. Early weed competition can be as important in reducing crop yield as weed competition for the entire season. The objectives of this study were (1) to determine the weed control achieved by narrow row-cropping patterns, (2)...

Techniques for studying the effects of various cropping systems on the germination of buried weed seeds

Creator:: Thorsen, Jack Arlen
Abstract:: The study of the effects of cropping systems on buried weed seed is very costly. Most of the experiments of this nature were conducted prior to the introduction of herbicides. New techniques, material and methods are needed and could result in more research in this area of study. A polyester...

Beans, cabbage, and sugar beets in a chemically suppressed sod of Manhattan II perennial ryegrass

Creator:: Rinehold, John W.
Abstract:: Crops were planted into tilled strips in an established perennial ryegrass (Lolium perenne L. 'Manhattan II'), sod covering various portions (55%, 66%, 77%) of the row width. Italian beans (Phaseolus vulgaris L. 'Romano II') biomass and yields showed a trend among sod strips with lower yields produced in plots with...
