In-field agronomic management practices mentioned include which of the following?

• A. In-field agronomic practices include 4R nutrient management, cover crops, tillage, and crop rotation.
• B. In-field practices include only irrigation management.
• C. In-field practices are unrelated to nutrient management.
• D. In-field practices focus on pest control exclusively.

Answer: (B)

In-field agronomic management practices are actions applied directly in the field to influence crop growth, with irrigation management often highlighted as a primary example because it directly controls water availability and soil moisture. When the material mentions in-field practices, irrigation management is the specific area called out, since water status strongly affects plant health, nutrient use efficiency, and yield. The other options list additional practices that can be part of comprehensive field management—such as nutrient strategies, soil cover, soil disturbance, and crop sequencing—but if the source text focuses on irrigation as the described in-field practice, that is the best match for what was mentioned in that context.
