Jointing
The developmental stage in cereal crops where the first stem node appears above the soil surface and internodes begin to elongate.
Также говорят: stem elongation, shooting
Jointing is a vital growth stage determining the yield potential of cereal crops. During this period, the plant undergoes rapid stem elongation and differentiation of reproductive structures, requiring optimal nutrient availability and moisture levels.
Practically, this phase marks the timing for critical field operations such as top-dressing fertilizers and applying plant growth regulators to prevent lodging. Monitoring the crop precisely at this time is essential to manage weed pressure and pest infestations before the canopy closes.
A common management error is failing to provide adequate nitrogen supplies, which restricts the potential number of grains per spike. Additionally, late application of certain herbicides can cause physiological stress, negatively impacting the crop's development and total yield.
