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 .
BBCH-scales have been developed for a range of crop species where similar growth stages of each plant are given the same code. Phenological development stages of plants are used in a number of scientific disciplines ( crop physiology , phytopathology , entomology and plant breeding ) and in the agriculture industry ( risk assessment of ...
This template presents a comparison table for major staple foods. It is intended to be transcluded into other pages. If it is transcluded into an article for one of the staple foods listed in the table e.g., the Wheat article, then the column for that food will be automatically highlighted.
The first documented Africans were brought to Maryland in 1642, as 13 slaves at St. Mary's City, the first English settlement in the Province. [1] Slave labor made possible the export-driven plantation economy. The English observer William Strickland wrote of agriculture in Virginia and Maryland in the 1790s:
Some of the traditional tools of cultivated plant taxonomy including: microscope, camera, flowers and book to assist identification. Cultivated plant taxonomy is the study of the theory and practice of the science that identifies, describes, classifies, and names cultigens—those plants whose origin or selection is primarily due to intentional human activity.
Early in the season, many species of birds and rodents feed upon wheat crops. These animals can cause significant damage to a crop by digging up and eating newly planted seeds or young plants. They can also damage the crop late in the season by eating the grain from the mature spike.
Harvesting a cereal with a combine harvester accompanied by a tractor and trailer. Cereal grains: (top) pearl millet, rice, barley (middle) sorghum, maize, oats (bottom) millet, wheat, rye, triticale. A cereal is a grass cultivated for its edible grain. Cereals are the world's largest crops, and are therefore staple foods.
This is a list of countries by cereal production in 2023 based on the Food and Agriculture Organization Corporate Statistical Database. The total world cereal production for 2023 was over three billion metric tons. The per-capita world cereal production for that year was about or nearly 400 kilograms per person. [citation needed]
