classified as genetic or environmental.
A. Genetic Factor
1. Field crops - Yield potential is determined by genes of the plant. A large part of the increase in yield over the years has been due to hybrids and improved varieties. Other characteristics such as quality, disease resistance, drought hardiness are determined by the genetic makeup. Corn hybrids are an example of a dramatic yiel incease resulting from genetics. Genetic engineering is now becoming an important tool in changing a plants potential.
2. Nursery crops and turf - not interested in total growth as much as appearance. Ex. is Bermudagrass
1. Coastal bermudagass- As a forage the grower is interested in yield and feed quality.
2. Tifdwarf - Golf greens - interested in appearance, cover, wear resistance not how much total growth occurs.
3. Variety and Plant Nutrient needs-Hybrid corn producing 200 bu/ac requires more plant nutrients than a hybrid producing 100 bu/ac. As potential crop yields are increased, the plant nutrients required are increased. Current research in the Soil Science and Genetics department is concerned with developing corn hybrids that use nitrogen more efficiently - Produce more grain per pound of N - fertilizer.
4. A producer has control over the genetic factor by his choice of variety.
