Study Notes
Agronomy and Applied Sciences
- Agronomy applies biological, physical, and social sciences, including biology, chemistry, physics, and economics, to understand and manage agricultural systems.
Plant Breeding in Agronomy
- The focus of plant breeding in agronomy is to develop crop varieties with desirable traits, such as increased yield, disease resistance, and improved nutritional quality.
Impact of Plant Breeding on Crop Yields
- Plant breeding has significantly impacted crop yields by increasing them through the development of high-yielding crop varieties, which has contributed to global food security.
Scope of Agronomy
- Agronomy encompasses the study of crops, soil, and water management, as well as the interaction between these components and the environment.
Example of Hybrid Grain
- An example of a hybrid grain resulting from plant breeding is hybrid corn, which has been developed to have higher yields, improved disease resistance, and increased tolerance to environmental stresses.
