1. the growth and development processes of the rice plant, particularly the interdependence
between tillering and root growth, and how this enhances grain
formation;
2. how these processes may be affected by environmental factors such as temperature,
light intensity, day length, humidity, soil moisture and aeration, and
plant nutrient availability; and
3. how the various agronomic management practices, when taken together, can
benefit the development and yield of a rice crop through synergistic effects.
