Plant Height — Smooth Brome

Bromus inermis Leyss.

Plant height in smooth brome is a key morphological trait influencing biomass productivity and forage quality, typically ranging from 60 to 160 cm.

In the reference 5 varieties crop Smooth brome, where this is mentioned in the description.

The stem height range of smooth brome depends on varietal characteristics, agroclimatic conditions, and the age of the stand. Maximum plant development is typical for the third year of growth, whereas in the year of sowing, values depend significantly on moisture availability, reaching 86–114.5 cm under favorable conditions. Varieties with stem heights of 100–150 cm are traditionally classified as highly productive and most leafy.

This trait has a direct correlation with dry matter yield, making it a determining factor in evaluating breeding lines and selecting varieties for specific soil and climatic zones. Plant height also dictates the timing of agrotechnical measures: excessive prolongation of the vegetation period leads to stem coarsening and a reduction in forage quality; therefore, the optimal mowing stage is closely linked to the crop's growth dynamics.
