Information from related Agronomy events

Contest Purpose:  To create interest and promote understanding of agronomy through the demonstration of skills and proficiencies.


  1. To demonstrate basic knowledge of agronomic principles and practices.
  2. To explore career opportunities, skills, and proficiencies in the agronomy industry.
  3. To determine the ability to identify agronomic:
Crops Diseases
Weeds Plant nutrient deficiencies
Seeds Grain and seed grading
                   . Insects         . Crop inputs
  1. To evaluate real world scenarios and make sound agronomic decisions.
  2. To demonstrate an understanding of integrated pest management and best management.

The event will consist of three parts. An Agronomic Quiz and Calculations section will test general knowledge. An Annual Practicum of plant identification, soils, and grain grading will be used every year. A Rotational Practicum of seed grading, general fertilizer knowledge, and insect identification were used in 2001 and odd years thereafter. In even years (i.e. 2002), nutrient deficiency, herbicide and pesticides, and plant diseases will be emphasized.

The three parts of the contest and their point values are shown:
                     . Part 1       . Agronomic quiz and calculations 20 questions      . 200 pts
Part 2 Annual Practicum 250 pts
Part 3 Rotational Practicum 250 pts
