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.
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. [43]
The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre. Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution .

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.
Rapeseed, alfalfa, barley, canola, flax, rye, and oats are other popularly grown grain crops. Wheat is a staple crop from Canada. To help homesteaders attain an abundance harvest in a foreshortened growing season, varieties of wheat were developed at the beginning of the twentieth century.
A seed rate of about 100 kg of seed per hectare (2 bushels per acre) is typical, though rates vary considerably depending on crop species, soil conditions, and farmer's preference. Excessive rates can cause the crop to lodge, while too thin a rate will result in poor utilisation of the land, competition with weeds and a reduction in the yield.
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 .
Western US – One of the best spring forage sources for honeybees. Blooms 45–60 days and continuously produces nectar throughout the day. Can be seeded several times per year. Prefers 3 ft of topsoil. 180–1,500 pounds honey per acre, depending on soil quality and depth; 300–1000 pounds of pollen. [9] G, H Plantain: Plantago Major ...
