Agronomy is a branch of agriculture that focuses on soil management and crop production. It mostly deals with large fields and requires relatively little management. Agronomy resolves the challenges related to crop yield, crop diseases, pest control, plant breeding, cultivation, weed management, climate change, and soil. Crop science is another major branch of agricultural science that deals with developing new crop types and protecting plants from diseases and climate stress. Several companies are investing hugely in crop science research and development. The rising demand for food and agricultural products has driven the demand for advancements in crop sciences, including biotechnology and marker-assisted plant breeding, RNA interference, next-generation sequencing, nanotechnology, and many more.
