The results show that planting more pounds per acre of rye increased the cover crop's production as well as decreased the amount of weeds. The same was true when scientists tested seeding rates on legumes and oats; a higher density of seeds planted per acre decreased the amount of weeds and increased the yield of legume and oat production.
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.
Usually a seeding rate of 13–20 kg/ha (12–18 lb/acre) is recommended, with differences based upon region, soil type, and seeding method. [42] A nurse crop is sometimes used, particularly for spring plantings, to reduce weed problems and soil erosion, but can lead to competition for light, water, and nutrients.

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.
The Feekes scale is a system to identify the growth and development of cereal crops introduced by the Dutch agronomists Willem Feekes (1907-1979) in 1941. [ 1 ] [ 2 ] This scale is more widely used in the United States [ 3 ] than other similar and more descriptive [ 4 ] [ 5 ] scales such as the Zadoks scale or the BBCH scale .
In Brazil, conversion to no-till methods combined with intensive crop rotations has been shown an SOC sequestration rate of 0.41 tonnes per hectare per year. [ 25 ] In addition to enhancing crop productivity, sequestration of atmospheric carbon has great implications in reducing rates of climate change by removing carbon dioxide from the air.
AC Hazlet rye is a fall rye variety that was developed by Canadian breeder Dr. Grant Macleod of Agriculture and Agri-Food Canada. [1] AC Hazlet rye is a medium-sized fall rye variety whose seed crop is produced and distributed through SeCan, a not-for-profit Canadian commodity crop seed distribution cooperative, and is then grown on a commodity scale in Canada [1]
