A research on crabgrass and its importance as a forage and crop throughout history

However, for pitted, sharppod, and the hybrid morningglories, pubescence on leaves and petioles varied among and within accessions. The crop—weed interaction is not quite this simple for several reasons. European colonists carried common lambsquarters Chenopodium album to the New World as a vital source of early season greens that prevented scurvy and other nutritional deficiency conditions.

However, the major use area is Kansas and states south and east to the coasts. By 12 to 14 DAT, most dry bean classes started to out grow the injury; however injury in the adzuki beans increased. Defoliation heights can be tolerated to as low as 3 inches, stands can be ready to graze at 6 inches, and cutting for hay should occur during early boot or about 18 inches high.

References and Citations Altieri, M. But, it too, can be used for chopped forage, silage and hay or straw feeds. Pour full strength vinegar or a heavy amount of sugar on each clump, but physical removal is usually needed. In units including bermudagrass, it will gradually take over. In both surveys, mean plant density was greater for populations found along railways than roads.

Dry matter yield typically ranges from 2 to 5 tons per acre. Of course, crude protein CP is critical. Developing methods for detection of glyphosate drift on corn would allow producers to determine potential crop damage and make appropriate management decisions.

Imazamox injury reduced alfalfa yield at the first harvest in the clear seeded system in both establishment years. There are many variations. The primary objective of this study was to document their occurrence along roads and railways in the province of Saskatchewan, where half of all canola is grown, and at the port of Vancouver, British Columbia on the west coast of Canada where most canola destined for export is transported by rail.

No glyphosate injury was observed in The crude protein CP concentration of crabgrass declined in a narrow range from 21 percent in the vegetative stage in July to Seed were then hand thrashed, seed were then sown in pots containing standard potting media which were then placed in a growth chamber with diurnal settings of 30 C for 16 h and 20 C for 8 h.

An Ecological Understanding of Weeds

We are assuming here that volunteer crabgrass is already in place and that rotational grazing of all forage is the usual. Glyphosate injury was minimal, short-lived and no longer evident at the first harvest in This alters the tillage and fall planting techniques.

In addition, the effects of tillage, a rye Secale cereale L. Similarly, ethofumesate effects on kochia control were negligible when triflusulfuron was included in the postemergence herbicide combinations.

With a little diligence and timely weeding, the home gardener can turn most weeds into beneficial organic matter. It possesses the highest nutritive value of all commonly grown forage plants. In an examination of 23 varieties of pearl millet, forage pearl millet seems to be more sensitive than the grain pearl millet varieties.

Protect the soil from erosion Replenish organic matter, and feed and restore soil life Absorb, conserve, and recycle soluble nutrients that would otherwise leach away Absorb carbon dioxide from the atmosphere see sidebar Restore biodiversity Provide habitat for insects and animals It is important to understand that this flush of weed growth is, in effect, a healing response to land disturbance after either natural disaster or human activity leaves the soil vulnerable to erosion or degradation.Crabgrass as a Forage and Hay Crop 2 forage yields can range from only 1 to more than 5 tons/ acre, typically dry matter ranges from 3 to 5 tons/acre.

On going research at the Southern Piedmont AREC is evaluating the yield, nutritive value, and persistence of both sprigged and seeded bermudagrasses. Crabgrass It is commonly considered a weed due to its prolific growth habit.

Crabgrass has a much maligned history but has gained favor as a high-quality forage over the past couple decades. For years, producers noticed that livestock readily grazed this “weedy grass,” but work from the Noble Research Institute brought it to the forefront as a valued forage when the variety “Red River” was released.

Extension publications including fact sheets, GardenNotes, and publications for sale. Topics include: agriculture crops, agriculture and farm management, agriculture and livestock; energy; Family, Home & Consumer including energy, kids, elderly and relationships, finances and work, and housing; Insects including Exotic (non-established in Colorado), field and forage crop.

Dairymen using good crabgrass pasture as a lactating cow forage repeatedly state that milk production increases 25 to 30 percent when the cows graze the pasture or are fed good crabgrass hay or silage, apparently because of higher palatability and digestibility and good protein content.

Meeting Abstracts

annual summer pasture throughout the south-central and southeastern United States. During its history, Red River became the main commercial cul- tivar promoting the use of crabgrass as an important warm-sea-son annual grass for forage and livestock operations, initially in.
