Tillering coefficient
An agronomic index representing the average number of productive stems or tillers produced by a single plant in cereal crops.
Также говорят: tillering capacity, number of tillers per plant
The tillering coefficient is a vital metric for assessing crop development and potential yield. It measures the plant's ability to branch out from the basal node, which directly influences the number of spikes or panicles per unit area.
Factors such as seeding rate, nutrient availability, and light penetration significantly affect this process. If the seeding rate is too high, competition for resources increases, which suppresses tillering and results in weaker plants. Conversely, proper management encourages the development of productive stems.
A common mistake is neglecting early nitrogen application, which is crucial for stimulating tiller formation. Farmers should monitor field density closely to ensure that the tillering coefficient aligns with the agronomic target for specific environmental conditions.
