Presentation of Pioneer's "PR39F58" maize at Werktuigendagen, Belgium 2009 Presentation of Pioneer's corn seeds near Lahr in Germany. The headquarters of Dupont Pioneer are located in Johnston, Iowa, with additional offices around the world. Pioneer produces, markets and sells hybrid seed corn in nearly 70 countries worldwide.
Fallow syndrome is when a crop has insufficient nutrient uptake due to the lack of arbuscular mycorhizae (AM fungi) in the soil following a fallow period. Crops such as corn that are prone to fallow syndrome should not follow a period of fallow, but instead should follow a cover crop which is a host for AM fungi, such as oats or other small grain crops.
Seeds yielded $264 million in 2012, supporting 1,400 workers. Seeds exceeded the value of the state's next several largest crops combined—including sugarcane and macadamia nuts. [4] As of 2008 genetically engineered corn seed was the top crop by value in Hawaii. It made up 92 percent of the state's GM seed industry. [citation needed]
Cutting down on wasted seed was important because the yield of seeds harvested to seeds planted at that time was around four or five. The seed drill was introduced from China to Italy in the mid-16th century where it was patented by the Venetian Senate. [65] Jethro Tull invented an improved seed drill in 1701. It was a mechanical seeder which ...

A four-ox-team plough, circa 1330. The ploughman is using a mouldboard plough to cut through the heavy soils. A team could plough about one acre (0.4 ha) per day. The typical planting scheme in a three-field system was that barley, oats, or legumes would be planted in one field in spring, wheat or rye in the second field in the fall and the third field would be left fallow.
Pioneer species tend to be fast-growing, shade-intolerant, and tend to reproduce large numbers of offspring quickly. The seeds of pioneer species can sometimes remain viable for years or decades in the soil seed bank and often are triggered to sprout by disturbance. [19] Mycorrhizal fungi have a powerful influence on the growth of pioneer ...
Exact dates are hard to determine, as people collected and ate seeds before domesticating them, and plant characteristics may have changed during this period without human selection. An example is the semi-tough rachis and larger seeds of cereals from just after the Younger Dryas (about 9500 BC) in the early Holocene in the Levant region of the ...
