💡Agronomy

Agronomy is the scientific study of soil management and crop production. In the context of the video, agronomy is defined as the agricultural science that deals with the principles and practices of crop production and field management. The script emphasizes how agronomy incorporates aspects like irrigation, fertilizers, pesticides, and sustainable farming techniques to maximize crop yields and maintain field health.

💡Crop Production

Crop production refers to the process of growing crops for food, fiber, or fuel. In the video, the topic of crop production is discussed in terms of practices that ensure better field management, the use of irrigation, and the right application of pesticides and fertilizers to increase yield. The explanation highlights how agronomists focus on efficient crop production methods to improve farming outcomes.

💡Field Management

Field management involves the careful planning and control of crop cultivation areas to enhance productivity. The video explains how agronomy focuses on proper field management techniques such as the construction of field channels and crop rotation practices to ensure soil fertility and water distribution. Effective field management ensures the sustainable use of resources, maximizing agricultural outputs.
