Variety traits

Lodging — Cannabis sativa

Cannabis sativa L.

A trait representing the resistance of a hemp stand to mechanical stress, evaluated on a scoring scale prior to harvest. High lodging resistance is critical for maintaining bast quality and ensuring the efficiency of mechanized harvesting.

In the reference 31 varieties crop Hemp, where this is mentioned in the description.

The evaluation of lodging resistance in Cannabis sativa is conducted using scoring scales, where maximum values correspond to the maintenance of an upright stem position until the end of the vegetation period. During variety trials, the type of lodging, its pattern, and the dynamics of plant conditions following exposure to adverse conditions, such as wind or heavy precipitation, are recorded.

Lodging is a negative factor, as contact between stems and moist soil increases the risk of mold and disease development, reducing the technical properties of the fiber. Furthermore, lodged plants impede the operation of harvesting machinery and lead to significant yield losses.

Key agronomic causes of hemp lodging include excessive nitrogen fertilization during the stem elongation period and non-compliance with seeding rates, which leads to excessive density and thinning of the stems. Varieties with high stem strength are the most preferred for intensive cultivation technologies.
