Plants are essential to life on earth. Either directly or indirectly, they are the primary food source for humans and other animals. Additionally, they provide fuel, replenish the earth's oxygen supply, prevent soil erosion, slow down wind movement, cool the atmosphere, provide wildlife habitat, supply medicinal compounds, and beautify our surroundings.

Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.
PR-798: 2021 Fruit and Vegetable Research Report
Ric Bessin, Win Dunwell, Nicole Ward Gauthier, Krista Jacobsen, Rachel Rudolph, John Strang, Raul Villanueva, Shawn Wright | Dec. 13, 2021 (New)
The 2021 Fruit and Vegetable Crops research report includes results from 12 different projects. The majority of projects were conducted on research farms, but a few were conducted on commercial farms with the assistance of grower-cooperators. We are truly grateful to the growers who invest their time, energy, and land in supporting research. Their contributions help other growers, and that is of immeasurable value. Research was conducted by University of Kentucky faculty and staff from the horticulture, plant pathology, and entomology departments, as well as faculty and staff of Kentucky State University.
