Nutsedge: Weedy Pest or rake of the Future?
Yellow nut grass (genus Cyperus esculentus L.) is an invasive weed in the United States. It is often regarded as a uneffective pest to home gardeners as well(p) as commercial growers. Along with being a useless weed it is difficult to control. Several commercial herbicides have been labeled for use exclusively on lily-livered nut grass and ar available at local retailers. This, of course, indicates oft research has foregone into the development of chemicals to eradicate it. In a country that spends much of its time and money on programs focusing on the publicity of crop production has the yellow nutgrass been labeled unfairly? Could the U.S. find use for Cyperus esculentus L.? A look into its aside and present might reveal a profitable future.
Cyperus esculentus is in the order Commelinales and the family Cyperaceae. Cyperus esculentus keep be distinguished from other species of New World nutsedge by its persistent linear brown spiklets that have close appressed overlapping scales. This perennial plant is self-incompatible. The stem of yellow nutsedge is triangularand has a light green-yellow color. Rhizomes that terminate in tubers be the main means of reproduction, although it does produce viable seed.
It is interesting to note that the name Linnaeus chose for this sedge, esculentus, means edible in latin (6).
The two varieties of interest to us are Cyperus esculentus var. esculentus (weedy) and Cyperus esculentus var. sativus (cultivated). Most literature uses the name Cyperus esculentus for two the weedy and the useful sedge.
The weedy compartmentalization esculentus produces many seeds although the cultivated variety sativus produces few. Yellow nutsedge (weedy) has been account to produce 605 million seeds per hectare in Massachusetts (4). Both manifold ve discoveratively in great numbers. Research indicates that a single nutsedge tuber can produce about 1900 plants...
