Livestock grazing comparison is a method of comparing the numbers and density of livestock grazing in agriculture. Various units of measurement are used, usually based on the grazing equivalent of one adult cow, or in some areas on that of one sheep. Many different schemes exist, giving various values to the grazing effect of different types of ...
Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
It is the principal grazing grass in New Zealand where some 10 million kilograms of certified seed are produced every year. There is a large range of cultivars . The primary species found worldwide and used both for lawns and as a forage crop is perennial ryegrass ( Lolium perenne ).
On US federal grazing land, the grazing fee for 2012 (as for 2011) is $1.35 per AUM. [3] As of 2015, the grazing fee has been increased to $1.69. [ 3 ] Over several decades, the fees charged on US federal rangelands have generally been substantially lower than rates charged on private lands in the US. [ 4 ]
Ryegrasses have high sugars and respond to nitrogen fertiliser better than any other grass species. These two qualities have made ryegrass the most popular grass for silage-making for the last sixty years. [timeframe?] There are three ryegrasses in seed form and commonly used: Italian, Perennial and Hybrid. [11]
In northwestern Nevada from 1984–1997 cheatgrass density was altered by changing the seeding rates of a variety of native and non-native perennial grass and forb seed mixes. Cheatgrass densities were reduced to 2.6 plants per sq. m with seeding rates of 22.5 – 25 PLS per sq ft. Cheatgrass densities of 4.07 and 3.58 plants per sq. m were ...
The seed ratio is another way of calculating yields. Cereal yield in tons per hectare and kilograms of nitrogenous fertilizer applied per hectare of cropland. Innovations, such as the use of fertilizer , the creation of better farming tools, and new methods of farming and improved crop varieties have improved yields.
Rye is a tall grass grown for its seeds; it can be an annual or a biennial. Depending on environmental conditions and variety it reaches 1 to 3 metres (3 ft 3 in to 9 ft 10 in) in height. Its leaves are blue-green, long, and pointed. The seeds are carried in a curved head or spike some 7 to 15 centimetres (2.8 to 5.9 in) long.
