Information from related Agronomy events
Contest Purpose: To create interest and promote understanding of agronomy through the demonstration of skills and proficiencies.
Objectives:
| Crops | Diseases | |
| Weeds | Plant nutrient deficiencies | |
| Seeds | Grain and seed grading | |
| . | Insects . | Crop inputs |
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 |
