Agronomy Fundamentals Quiz

Seed Quality

• High-quality seeds have high germination percentage, are free from diseases and pests, and have good genetic purity.
• They also have proper moisture content, are free from mechanical damage, and have a good seed coat.

Nutrient Use Efficiency

• Nutrient use efficiency (NUE) is the ability of a crop to absorb and utilize applied nutrients from the soil.
• It is a critical aspect of sustainable agriculture as it minimizes nutrient loss and reduces environmental pollution.

Tilth

• Tilth refers to the physical condition of soil in relation to its suitability for plant growth.
• It is a measure of soil structure, including its texture, porosity, and aeration, which affect root growth and water infiltration.

Puddling

• Puddling is a tillage operation that creates a shallow, flooded condition in the soil, which helps to control weeds and reduce soil erosion.
• It is an important aspect of modern tillage practices, particularly in rice cultivation, as it allows for better water management and soil aeration.

Planting Geometry

• Planting geometry refers to the arrangement of plants in a field, including the spacing between rows and plants.
• The types of planting geometry mentioned in the text include:
  • Square planting: where plants are spaced equally in all directions.
  • Rectangular planting: where plants are spaced more closely in rows than between rows.
  • Triangular planting: where plants are spaced equally in all directions, but with a triangular pattern.
